@section Installing RHIDE

There are two archives

@table @file
@titem rhide??b.zip
This contains the executable and the documentation for RHIDE

@titem rhide??s.zip
This contains the sources for RHIDE.

@end table

where @file{??} in the above filenames stand for the digits of the actual
version of RHIDE.

@paragraph{}

These archives can be found at
@www{The RHIDE home page, www.tu-chemnitz.de/~rho/rhide.html}
or at any ftp site, which mirrors DJGPP.
@paragraph{}

To install these archives, you have to unzip them in the DJGPP-root
directory, like any other DJGPP package.
@paragraph{}

@subsection Configuring RHIDE
@cindex Configuring RHIDE

In most cases you have to do nothing for configuring RHIDE. But there are
some special things, which must be configured which have mostly to do with
the editor (or better) the keyboard layout.
@paragraph{}

The editor of RHIDE is configurable for the keyboard. For this it uses a
text file @file{keybind.txt}, which is searched in the following
directories (in that order). If it was not found in any of these
directories RHIDE uses builtin defaults. For more information about
creating (customizing) the file and about the syntax of that file
@extref{Keyboard,Documentation about the keyboard,editor.inf,SET's editor,editor.html}

@itemize @bullet
@item The current directory
@item @file{%DJDIR%/data}
@item The directory, where @file{rhide.exe} is stored
@end itemize
@paragraph{}

The binary archive of RHIDE includes already the config files for
the US keyboard layout (@file{us.txt}) and many others, which are based
on the Linux keytables. If you have problems with the keyboard layout
try to copy one of the files to @file{keybind.txt} (probably the one,
which has a name similar to your country).
@paragraph{}

RHIDE also contains the file @file{keybind.txt} which IS @file{us.txt}.
@paragraph{}

As an example,
if your are using a german keyboard, and you have installed @file{keyb.com}
as your keybord driver program, you need to copy @file{de.txt} to
@file{keybind.txt} otherwise (for example) the keys @key{y} and @key{z}
are exchanged.
@paragraph{}

If you are using a keyboard driver (like I), which converts the scancodes
of the keys (@file{keyb.com} does that NOT) you will probably not need
the file @file{de.txt} (but the default @file{keybind.txt}).
@paragraph{}


@section What is RHIDE?

What is RHIDE? RHIDE is an Integrated Development Environment for 
compiling C- or C++-files (GNU-Assembler source files also supported)
in an environment, which has an integrated editor where you can edit your
source files and a project management, where you can define, which
files are needed to build a program or a library.
@paragraph{}

For what stands the name RHIDE? This has nothing mystic in it. It comes
simply from my initials RH and IDE (Integrated Development Environment).
@paragraph{}

RHIDE works like the IDE from Borland, which comes with Turbo C++ 3.1 and
is written with the Turbo Vision library, which I have ported to use with
DJGPP. Features of this IDE are:
@itemize @minus

@item
Syntaxhighlighting is now supported and you can customize all
colors on your desktop.

@item
You can redirect the stdout and stderr from your program to
a window in the IDE.

@item
You can generate a makefile for your project, so you can build
the program also without the IDE.

@item
Most of the commandline-options of gcc can be customized.

@item
You can also build a library instead of an executable.

@item
When saving a file to disk, the modification time of this file
will be set to the time of the last modification in the editor.

@item
You can interrupt external programs (the compilers or your
program) by pressing @ikey{Ctrl+C,Ignoring} or
@ikey{Ctrl+Break,Interrupting the compilers},
which are ignored by the IDE. That means also, that you cannot interrupt the
IDE by pressing these keys. If you want to enable this, compile
the IDE without the @samp{-DNO_BREAK}-flag.

@item
The integrated debugger. You can debug your program within RHIDE by
executing each source line of your code and evaluating/modifying variables
and expressions.

@item
You can define other compliler to compile your source files.

@end itemize
@paragraph{}

In addition to RHIDE I have included a standalone debugger
(called @file{rhgdb.exe}), which is GDB 4.16 with a Turbo Vision user
interface.
@paragraph{}

@section Requirements

RHIDE works under and is compiled with DJGPP V2.01.
To compile your programs you need
a working GCC-configuration, that means, gcc must be found in your 
path. Because DJGPP works only under DPMI you need a DPMI-Server.
If you run it under Windows 3.1(1)/95, you have DPMI. Under MS-DOS you
need either a memory-manager, which give you DPMI-services (I think QEMM is
it, EMM386 has no DPMI-support), or you use CWSDPMI, the free DPMI-server
from Charles Sandman, which you can find on SimTel-ftp-sites. I use it
and it works fine for me.
@paragraph{}

The builtin editor uses a simple heuristic to check, if a file
is in UNIX or DOS text format. It checks the first 1024 Bytes, and if
there is a lf without a cr, all lf's will be translated to cr/lf's. This
is done at first only in memory. But if you save your file to disk,
it will be saved in DOS text format.
@paragraph{}

At this time the program is only
tested with a SVGA-video card (et4000), I don't know if it works with
other cards, but I think so.
@paragraph{}

@section Getting started
@cindex Start
@cindex Commandline options

To run RHIDE type
@display
rhide [options] ['file-name']
@end display
or 
@display
rhide [options] 'project-name' [options]
@end display
Here stands 'file-name', for a file, which you want to open at start up.
If it has no suffix it is assumed to be a 'project-name'.
@paragraph{}

'project-name' stands for a name of your project. If you don't type
it, RHIDE searches the current directory for a project file. If there exists
only one, it will be opened. If there exist more than one or none, RHIDE
will not open a project, you have to do it manually 
(@xref{Open project})
@paragraph{}

Possible options are
for debugging RHIDE itself (@xref{Debugging RHIDE}).
If no project was open, you will see an empty desktop.
At the top-line of the screen you can see the menu. This is activated by
pressing @ikey{F10,Menu} or by clicking with the mouse at this line.
Alternatively
you can press @key{Alt} plus the highlighted character of a pull-down
menu. e.g. to activate the @emph{File} menu, press @key{Alt+F}. At the
bottom-line you can see the statusline with some hotkeys and it functions.
@paragraph{}

Other options are:

@table @samp
@titem -y
Use long filenames (only under Windows 95)

@titem -n
Do not use long filenames (only under Windows 95)

@titem -c
Do not convert the case of any file name

@titem -h
Show a short help about all the possible options.

@titem -b
Use BIOS calls for setting and resetting the behaviour of the
7th bit in a color attribute (blinking or 16 background colors) instead of
direct outputs to the VGA registers.

@titem -k KEY_FILE
The editor in RHIDE is now configurable also for the keyboard.
The file, where the key bindings are stored is searched at
first in the current directory, then in the directory
@file{%DJDIR%/data}, and then in the directory where the
executable is. If all this fails default values are taken.
@paragraph{}

With this switch you can override the default name of @file{keybind.txt}
to whatever you want.

@titem -p
Normally RHIDE converts all the numpad keys to the equivalent keys on the
other keyboard (of course also by checking the num-lock key). With this
switch you can disable this.

@titem -G n
Select which methode is used for swapping the display. Currently there
are two little different functions are implemented.

If you have problems with display swapping when in graphics mode, try
to use an other methode and see if that helps.

@end table

At the upper right corner of the screen you can see the free virtual/physical
memory (where M stands for Megabytes, K for Kilobytes and B for Bytes), if
enabled (@xref{Preferences}).
@paragraph{}

If you try to open a project, which does not exist, RHIDE will create a
new one.
The way for creating a new project is done by RHIDE as follows.
If there exist in the directory of RHIDE (usually in %DJDIR%/bin) a
project file with the root name of the executable and the suffix @file{.gpr},
this file is copied as your new project file with all customizations, which
you have done in it. If this standard project file doesn't exist, a new
project file is created with the hardcoded defaults.
@paragraph{}

To create such a standard project file, change to the directory, where the
executable is and call the exe-file with the argument of its name without
the suffix @file{.exe}. After leaving the program, the standard project file
is created.
@paragraph{}

@subsection Supported languages
@cindex Languages

There is also support for multiple languages. For this RHIDE uses the
GNU gettext library. With this lib it is possible to support multiple
languages without changing any code of RHIDE, when adding a new language.
@paragraph{}

There are two ways for selecting the language. Either you set the environment
variable @var{LANGUAGE} to the language you want or give it as a commandline
argument to RHIDE. The normal way is by setting @var{LANGUAGE}. If you
have installed RHIDE like described in the @file{readme}, you should
specify the language with a two character shortcut. Here is the list of
the current supported languages together with the two character code:

@table @samp

@titem da
Danish maintained by @DANISH

@titem de
German maintained by @GERMAN

@titem es
Spanish maintained by @SPANISH

@titem fi
Finnish maintained by @FINNISH

@titem fr
Frensh maintained by @FRENSH

@titem it
Italian maintained by @ITALIAN

@titem nl
Dutch maintained by @DUTCH

@ignore
@titem pl
Polish maintained by @POLISH
@end ignore

@titem pt
Portuguese maintained by @PORTUGUESE

@ignore
@titem ru
Russian maintained by @RUSSIAN
@end ignore

@titem sv
Swedish maintained by @SWEDISH

@end table

When you want to specify the language on the commandline, use the following
syntax:
@format
rhide -L LANGUAGE
@end format
where LANGUAGE represents the language code.
@paragraph{}

If you do not specify any language, English is assumed.
@paragraph{}

Because it was not possible to get all the translations at the time
when RHIDE was ready, I included only the
message files (that are the files with the @file{.mo} suffix) as they
are ready in the binary archive. That means, that it is possible, that
you see some strings
in English instead of your language.
@paragraph{}

I will update the language files at the RHIDE homepage when they
are complete. You can then download and use them without recompiling
RHIDE simply by installing them in the correct directory.
@paragraph{}

@subsection Debugging RHIDE
@cindex Debugging

I have added some commandline options, to debug the IDE itself. These options
are the following:

@table @samp

@titem -dt
Do not remove the temporary files, which the IDE creates. The
names of these files will be printed to stderr.

@titem -dc
Print to stderr the commands which the IDE executes.

@titem -dd
Print to stderr how the IDE checks the dependencies.

@titem -df
Print to stderr how the IDE searches for files.

@titem -da
Turns on all of the above

@end table

You can also combine these options like @samp{-dct}, which is the same as
@samp{-dc -dt}.
@paragraph{}

To examine this debugging information, it is the best to use the redir
command, to redirect the stderr to a file like
@format
redir -e err rhide -da project
@end format
which will redirect stderr to the file @file{err}.
@paragraph{}

If you want to supply certain switches for RHIDE as a default,
you may put them into the environment variable @samp{$(RHIDEOPT)}.
The contents of
this variable is used before the the real commandline is parsed.
That means you can overwrite the switches from the environment variable.
@paragraph{}

@section The program GPR2MAK.EXE
@cindex Creating a makefile
This program can be used to create a makefile from your projectfile.
It does exctly the same like the function which is selectable from
the RHIDE menu (@xref{Write Makefile}).
@paragraph{}

In RHIDE you have only the possibility to say, if in the generated
makefile all dependencies should be included or not. With
@file{gpr2mak.exe} you can tell also to create recursively all the
needed makefiles. This makes sense only if you have included other
projects in your project.
@paragraph{}

Here are the possible commandline options for @file{gpr2mak.exe}.
@table @samp
@titem -d
Include all dependencies in the makefile

@titem -d-
Include only the needed dependencies to create the final program or
library.

@titem -r
Call @file{gpr2mak.exe} recursively, if there are other projects part
of the project.

@titem -r-
Do not call @file{gpr2mak.exe} recursively.

@titem -o OUTFILE
Use @samp{OUTFILE} instead of the project name (with the suffix @file{.mak})
as the created makefile. If you want to write the makefile to @code{stdout},
use @samp{-} as @samp{OUTFILE}.

@end table

And the complete syntax for calling @file{gpr2mak.exe} is also:

@display
@samp{gpr2mak.exe [-d[-]] [-r[-]] [-o OUTFILE] project-file}
@end display
@paragraph{}

If you give no options (the project-file must be given), @file{gpr2mak.exe}
assumes the flags @samp{-d- -r-} as default.
@paragraph{}


@chapter General information about how RHIDE works

In this section I will give you some comments about the concept of RHIDE.
RHIDE works with the GNU compilers. As a result of this, most of the
options are fixed and they are mostly also specific only for these
compiler. If I speak about compilers, I mean GCC, which calls the right
compilers for you.
(@file{cpp} for preprocessing your input files,
@file{cc1} for compiling C programs, @file{cc1plus} for
compiling C++ programs and @file{as} for compiling assembler files and so on)
@paragraph{}

Selecting the right compiler for a specific file is done by RHIDE in the
same way as GCC it does. It looks for the extension of the file
and determines the language of this file.
@paragraph{}

@section Known suffixes

The list of the known suffixes is taken from gcc. Remember the fact, that
gcc and RHIDE check the suffixes in a case sensitive way especially when
running under Windows 95 (@xref{Running under Windows 95}).

@itemize @bullet

@item Valid suffixes for C source files are
@table @file

@titem .c
Normal C source file

@titem .i
C source file, which doesn't need the preprocessor

@end table

@item Valid suffixes for C++ source files are
@table @file

@titem .cc
@titemx .cpp
@titemx .cxx
@titemx .C
Normal C++ source file

@titem .ii
C++ source file, which doesn't need the preprocessor

@end table

@item Valid suffixes for Objective C source files
@table @file

@titem .m
Normal Objective C source file

@end table

@item Valid suffixes for Pascal source files
@table @file

@titem .p
@titemx .pas
Normal Pascal source file

@end table

@item Valid suffixes for object files
@table @file

@titem .o
Normal object file

@titem
any other suffix,
which has no predefined meaning

@end table

@item Valid suffixes for libraries
@table @file

@titem .a
Normal library file

@end table

@item Valid suffixes for executable files
@table @file

@titem .exe
Normal executable file for MS-DOS

@titem .
No suffix means the raw COFF image of an executable file. These
can be handled only by programs, which know about this format.
(DJGPP programs know this)

@end table

@item Valid suffixes for include files
@table @file

@titem .h
Normal include files

@titem .hpp
Some people telled me, that this suffix should be treated also
as a valid suffix for header files, so I applied it.

@titem
Theoretically there is no restriction for such a suffix, but
RHIDE searches and finds only files with the above suffixes
in the specified directories (@xref{Include directories})

@end table
@ignore

@item Valid suffixes for flex source files
@table @file

@titem .l
Normal flex source file

@end table

@item Valid suffixes for bison source files
@table @file

@titem .y
Normal bison source file

@end table
@end ignore

@cindex Preprocessing Assembler files
@cindex Assembler files, which must be preprocessed
@item Valid suffixes for Assembler source files
@table @file

@titem .s
Normal Assembler source file

@titem .S
Assembler source file, which must be preprocessed
by @file{cpp}. If you have such files, there is a problem, when
long filenames are not enabled (default in MS-DOS), because
RHIDE converts all filenames in this situation to lower case. But you
can add to the local options for this item (@xref{Local options})
the commandline argument @var{-x assembler-with-cpp}, to tell
@file{gcc} to preprocess this file first before assembling it.

@end table
@end itemize

@section Syntax of arguments
@cindex Space as part of an argument

In RHIDE you can specify some arguments to other programs. These arguments
must be a space separated list of strings. If you want to have one or
more spaces as part of an argument, you have to enclose the whole argument
in single or double quotes.
@paragraph{}

@section Running under Windows 95
@cindex Windows 95
@cindex Long filenames
@cindex LFN
@cindex Temp directory
@cindex Directory for temp files

With DJGPP 2.01 were many bugs fixed, which caused problems under
Windows 95 with the long (and case sensetive) filenames. Now all filenames
are shown in lower case, except they contain characters
with different case. That means, all normal 8+3 DOS filenames, which
are normaly reported in Windows 95 in upper cases, are automatically
converted to lower case. For more information about  filename
conversion look at the libc reference.
@paragraph{}

If you really need the filenames exactly  as they are reported by the
OS, you can use the @var{-c} switch (@xref{Getting started}).
@paragraph{}

You can also run more than one instance of RHIDE at once, in several DOS-boxes,
because RHIDE creates and uses its own temp directory every time it starts to
disable conflicts, when running multiple compilers at the same time. This is
done by creating a directory in the directory pointed at by the environment
variables %TMPDIR%, %TEMP% or %TMP%, in that order, until one of them exists. If
none of them exists, the current directory is assumed. Then RHIDE puts the value
of this directory into the environment variable %TMPDIR%. After leaving RHIDE
this directory will be removed, if it is empty. @paragraph{}

@section Running under OS/2
@cindex OS/2

Because I have no access to OS/2, I cannot say anything about it. But
some people said  that they run RHIDE under OS/2 successfully, but there
must be the exclusive mouse access to the DOS window disabled.
@paragraph{}

@section General use of RHIDE

@subsection Creating a program

For creating a program, RHIDE allows you to define multiple source
files which should be compiled and linked to your final program. This
is done by creating a project. In this project you insert your source
files (and not all the include files).
@paragraph{}

After a source file (which is inserted in your project) compiled at least
once, RHIDE knows about all dependencies of this file, so this file will
be compiled again only, if one of the include files have changed.
@paragraph{}


@subsubsection Creating a program without a project

Because of many requests of users I made RHIDE to work also without
using a project. This may be good, if you have a single file, but if
your program should be build from more than one file I suggest you to
use a project.
@paragraph{}

If you have only one editor window opened, the name of the resulting
program is taken from the name of the source file by removing the suffix
and appending @file{.exe}.
@paragraph{}

If you have more than one files opened, I saw no other way for determining
the name of the produced program, than naming it @file{aout.exe}.

@subsection Creating a library

You can also create libraries (a collection of object files,
which can be linked with other programs) with RHIDE. The way for doing this is
very simple. Because RHIDE knows about the meaning of file suffixes, you can
change the name of the main target (@xref{Main targetname}) to have a suffix
@file{.a} and that's all. Now RHIDE will run @file{ar.exe} instead of linking

@paragraph{}

@subsection Saving/Loading the options
@cindex Save options
@cindex Load options
RHIDE supports two different ways for saving the options which you
have customized.
@paragraph{}

The first one (which I prefer) is the use of the so called default
project. This is the project @file{rhide.gpr} and must be located
in the same directory where @file{rhide.exe} is. To create or modify
this default project change to that directory (normally %DJDIR%/bin)
and type there

@format
rhide rhide
@end format

Now chnage any options you want and exit RHIDE. From now on these
options are used for any newly created project or when running
RHIDE without a project.
@paragraph{}

The second way is to save your options to a project file
(@xref{Save options}) or to load them from any existing project
file (@xref{Load options}).
@paragraph{}

@chapter Description of the pull-down menus

This chapter describes the pull-down menus and all their sub-menus.
The main menu bar, the topmost line of the screen, is selected with the
hotkey @ikey{F10,Menu} or by clicking with the mouse at this line. You can walk
through the menu with the cursor keys and a menu entry is selected with
@ikey{ENTER,Select menu item} or by clicking with the mouse on it.
@paragraph{}

@section System menu

This menu has its name only that one can speak about it. The symbol for this
menu is the leftmost symbol in the menu bar and can be selected by
@ikey{Alt+SPACE,System Menu}.
@paragraph{}

@subsection About
@cindex Version of RHIDE

This brings up a window with information about the author and the version
of RHIDE.
@paragraph{}

@subsection Bug report
@cindex Bug report
@cindex Reporting bugs
This menu entry opens an editor with some important information which
should be part of a bug report and where you can describe the problem.
@paragraph{}

@subsection FSDB
With this menu item you can call the FSDB debugger, which comes with
DJGPP. But remember, this runs the debugger as an external program and
it is not integrated in RHIDE.
@paragraph{}

@subsection GREP

This is a very useful function. You can type the arguments for grep
in the input line, which will be shown, and after this the program
grep is called. The messages from grep are redirected to the
message window (@xref{Message window}).
@paragraph{}

@subsection GDB

This is analog to the call of FSDB (@xref{FSDB}).
@paragraph{}

@subsection Refresh Desktop

This function is sometimes useful, if you had run your program and
it wrote some things to the screen (for redirecting @code{stdout}
and @code{stderr} from your program to a window in RHIDE
(@xref{Preferences})).
@paragraph{}

@subsection Calculator
@cindex Calculator
This brings up a dialog, where you can do some calcualtions. This
dialog is similar to the evaluate dialog (@xref{Evaluate/Modify}), but it
uses not the feature of gdb, but it is a separate calculator.
@paragraph{}

There can be used also some of the standard functions like
@samp{log}, @samp{sin} and so on and it can convert also integer
values between different bases (@samp{hex}, @samp{oct}, @samp{dec}).
@paragraph{}

@subsection Puzzle
This will open a small window, where you can play a little puzzle
game. The "stones" are moved with the cursor keys or by clicking
with the mouse on it.
@paragraph{}

@subsection Calender
This will open a little calender. With the cursor keys @key{Up} and
@key{Down} you can switch to the next/previous month or click with
the mouse the small symbols int the upper corners.
@paragraph{}

@subsection ASCII table
This will open a window with all the ASCII characters. Move around
with the curser keys or press any key to select any wanted charcter.
In the bottom line you will see the the character and the value
of it (decimal and hexadecimal). The decimal value can be used to
create that character for instance in the editor by holding the
@key{Alt} key down and typing the value on the numeric key pad.
@paragraph{}

@section File

In this menu you can find functions, which deal with files like open, close,
save and so on.
@paragraph{}

@subsection Open
@cindex Open a file
@cindex Loading a file
@cindex Edit a file

Brings up the file-open dialog, where you can select a
file to open (hotkey @ikey{F3,open a file}). This dialog
contains an inputline for the filename, a list of filenames, an information
window and the buttons for opening and canceling.
@paragraph{}

@cindex File open dialog
@cindex Default file mask
In the filename inputline you can type direct the file, which you want to
open or you can type any mask to list only some files. The default
mask is @file{*.cc}, but you can change this to anything and your last
typed mask is stored as the default mask for the next use. There is also
a history of your previous typed inputs available. This is selected when
you hit the down key or click at the small symbol at the end of the inputline
with your mouse.
@paragraph{}

The list of filenames shows all the files that correspond to the mask.
If this list is selected you can choose a file with the cursor keys, or
you can type the first letters of the filename you want, and the
bar is located at the first file, which has these letters as the first
characters. To open the file simply press @key{ENTER} or double click
with the mouse on it.
@paragraph{}

Below the list of filenames there is a small window with information
about the selected file (complete path, size, modification time).
@paragraph{}

To leave the dialog without opening a file press @ikey{ESC,Leaving a dialog}
@paragraph{}

@subsection New
@cindex Creating a new file

This is the menu entry for creating a new file to edit. This file gets
the title 'Untitled'. If you save or close it, you will be prompted
for a new name of this file by opening the file-open dialog.
@paragraph{}

@subsection Save
@cindex Save the file to disk
@cindex Store a file

Save the file in the current editor-window to disk. If
the name of the current file is 'Untitled' you will be prompted for
a new name. This function has the hotkey @ikey{F2,saving a file}.
The modification of the file on disk is set to the time of the last
modification of this file and not to the time when saving to disk.
@paragraph{}

If the file was not modified, it is not saved!!
@paragraph{}

@subsection Save as
@cindex Save the file under a different name

Save the file in the current editor-window to disk under
a different name, for which you will be prompted. For choosing the
new name the file-open dialog will be opened.
@paragraph{}

@subsection Save all
@cindex Save all files to disk

Save all the editor files to disk. If they are not
modified, they will not be saved. 
@paragraph{}

@subsection DOS Shell
@cindex DOS
@cindex temporary do to DOS
@cindex MS-DOS
@cindex COMSPEC

This executes a DOS-Shell. This is done by calling the program,
which is set in the environment variable COMSPEC. If this variable
does not exist, the program @file{c:/command.com} is executed.
To return to the IDE type
@kbd{exit} at the DOS-prompt. Before calling DOS, the program does
a @emph{Save all} (@xref{Save all}) automatically.
@paragraph{}

@subsection Exit
@cindex Exit
@cindex Quit
@cindex Leaving RHIDE

Here you can quit the IDE. If there are any unsaved editor-files,
you will be prompted for saving them. (hotkey @ikey{Alt+X,Leaving RHIDE})
@paragraph{}

@section Edit

In this menu you can activate functions, which are related to the integrated
editor. Most of them have a hotkey.
@paragraph{}

@subsection Undo
@cindex Undo

This undoes your last change in the current editor-window. The hotkey for
this function is @ikey{Alt+Backspace,Undo}.
@paragraph{}

@subsection Redo
@cindex Redo
This does the reverse to undo (@xref{Undo}). That means, it is the undo
of the undo.

@subsection Cut
@cindex Cut

This @emph{moves} the selected text in the current editor-window to
the clipboard. (hotkey @ikey{Shift+Del,Cut})
@paragraph{}

@subsection Copy
@cindex Copy

This @emph{copys} the selected text in the current editor-window to
the clipboard. (hotkey @ikey{Ctrl+Ins,Copy})
@paragraph{}

@subsection Paste
@cindex Paste

This inserts the selected text in the clipboard in the current
editor-window at the current cursor-position. (hotkey @ikey{Shift+Ins,Paste})
@paragraph{}

the clipboard. The contents of the clipboard will be lost, if you 
exit the IDE.
@paragraph{}

@subsection Clear
@cindex Clear
@cindex Delete the selected text

This erases the selected text in the current editor-window.
@paragraph{}

@subsection Expand all tabs
@cindex Expanding tabs
@cindex Tabs to spaces
When selecting this menu entry, all real tabs (all characters with
the code @code{0x9}) are expaned to as many spaces as defined as
the tabsize (@xref{Preferences}).

@subsection Compact text
This function is the reverse to (@xref{Expand all tabs}). That means,
RHIDE tries to make as many as possible spaces (count is taken from
the defined tabsize) to real tabs.

@subsection Macro
@cindex Macros
Here is a submenu for handling macros. Currently there is
only one recordable macro available and it is NOT stored anywhere. That
means it is lost when you leave RHIDE and restart it. There is an other
way of using macros (@xref{Defining macros}).

@subsubsection Record
@cindex Starting a macro
@cindex Macro recording
After selecting this function, all your keystrokes are recorded to
reproduce them later.

(hotkey @ikey{Shift+F10,Macro start})

@subsubsection Stop
@cindex Stopping a macro
@cindex Macro stop recording
This stops the recording of a macro.

(hotkey @ikey{Alt+F10,Macro stop})

@subsubsection Play
@cindex Using the macro
@cindex Playing the macro
@cindex Macro executing
This executes the recorded macro.

(hotkey @ikey{Ctrl+F10,Macro play})

@section Search

Menu for searching and replacing strings in the editor-window. These functions
have also hotkeys.
@paragraph{}

@subsection Find
@cindex Searching text
@cindex Finding text

Find a string in the current editor-window. You can type the string for
searching in an inputline and you can also select, if the search is
case sensitive or not and to search for whole words only or not.
@paragraph{}

(hotkey @ikey{Ctrl+Q+F,Find})
@paragraph{}

@subsection Replace
@cindex Replacing text

Find and replace a string in the current editor-window. This works in the
same way like searching text, but additionally you can give a string, with
which the found text will be replaced.
@paragraph{}

(hotkey @ikey{Ctrl+Q+A,Replace})
@paragraph{}

@subsection Search again
@cindex Repeat of searching
@cindex Repeat of replacing

This function repeats the last search or replace operation.
@paragraph{}

(hotkey @ikey{Ctrl+L,Search again})
@paragraph{}

@subsection Goto line
@cindex Goto a line number

After prompting for a line number (with range checking),
the cursor will be located at this line.
@paragraph{}

(hotkey @ikey{Ctrl+J,Goto line})
@paragraph{}

@subsection Jump to function
@cindex Search a function
With this feature you can easily jump to the source line of a function
to edit or see it. This is only a heuristic by parsing your source
file and does not take the information from the debugging symbols.
@paragraph{}

After selecting it you will get a dialog, from where you can select the
function to which you want to jump.
@paragraph{}

(hotkey @ikey{Alt+F2,Jump to function})

@subsection Next message
@cindex Next message

This selects the next message in the message window (@xref{Message window}),
but only, if there is a next message available.
@paragraph{}

(hotkey @ikey{Alt+F8,Next message})
@paragraph{}

@subsection Previous message
@cindex Previous message

This selects the previous message in the message window (@xref{Message window}),
but only, if there is a previous message available.
@paragraph{}

(hotkey @ikey{Alt+F7,Previous message})
@paragraph{}

@node RUN
@section Run

In this menu you find the functions for running your program.
@paragraph{}

@subsection Run
@cindex Running your program
@cindex Starting your program
@cindex Executing your program

If your project-target is an executable, this will be run after doing
a Make (@xref{Make}). (hotkey @ikey{Ctrl+F9,Run}) If building the program was
not successful, the programm will not be started. The debugging functions
are only available if @samp{-g} was used for compiling.
(@xref{Syntax of arguments})
@paragraph{}

@subsection Step over
This executes the code for exactly on source line. If there is a function
call at the current line this function is executed at once without
stepping through this function.

(hotkey @ikey{F8,Step over})

@subsection Trace into
This is the same as Step over (@xref{Step over}), except when there is a
function call at the current line and for this function debugging
information is available, RHIDE steps into this function.

(hotkey @ikey{F7,Trace into})

@subsection Go to cursor
This will execute your program until the execution comes to the line,
where the cursor is. If the program is stopped at any other place
by a breakpoint the program will stop there and not at the cursor
position.

(hotkey @ikey{F4,Go to cursor})

@subsection Program reset
This 'kills' your debuggee at the current execution point without
executing any other code of your program

(hotkey @ikey{Ctrl+F2,Program reset})

@subsection Arguments
@cindex Arguments for your program
@cindex Commandline arguments for your program

Here you can type the arguments, which will be passed to
your program when you do a @emph{run}. (@xref{Run}) and 
(@xref{Syntax of arguments}).
@paragraph{}

@section Compile menu

Here are the functions to translate your source files and for updating your
project.
@paragraph{}

@subsection Compile
@cindex Compile

Compile the file in the current editor-window or the selected
entry in the project-window if you are there. The IDE chooses automatically the
correct compiler, depending on the suffix of the file. 
(@xref{Known suffixes})
@paragraph{}

(hotkey @ikey{Alt+F9,Compile})
@paragraph{}

@subsection Make
@cindex Make

This makes your project up to date. It works like MAKE on commandline
with a makefile. (hotkey @ikey{F9,Make}) This is done by checking the dependencies
for each item of the project. These dependencies are automatically generated,
if you compile a file within the IDE.
@paragraph{}

@subsection Link
@cindex Link the program
@cindex Build the library

This function has two different results depending on the type of your
project. If your project is an executable (@xref{Known suffixes}), the linker
is started. But if it is a library, all the object files are taken to
build a library.
@paragraph{}

@subsection Build all
@cindex Build

This builds the project completely new with compiling and linking
all of the project-items.
@paragraph{}

@section Debug
@cindex Debugging with RHIDE
This menu conatains the functions for debugging your program. Most of them
have hotkeys and they are described more detailed later
(@xref{Debugging with RHIDE}).

@subsection Set/Reset Breakpoint
@xref{Setting a breakpoint}
@paragraph{}

(hotkey @ikey{Ctrl+F8,Toggle a breakpoint})

@subsection Evaluate/Modify
@xref{Evaluating the contents of variables}
@paragraph{}

(hotkey @ikey{Ctrl+F4,Evaluate/Modify})

@subsection Watch an expression
@xref{Watching the contents of variables}
@paragraph{}

(hotkey @ikey{Ctrl+F7,Watch an expression})

@subsection Breakpoints
@xref{Modifying and setting a breakpoint}
@paragraph{}

@subsection Call stack
@cindex Function call stack
@cindex Call stack
This shows a window with a list of functions, from which the current
execution point in the debugged program are called from. If
you hit @key{Enter} on a function which has line number debugging
information, you will go to the source line which is shown in the
window.
@paragraph{}

(hotkey @ikey{Ctrl+F3,Call stack})

@subsection List of Functions
This asks first for a regular expression to list only those functions
of your program, which match that expression. The syntax for such
a regular expression is a little bit different from the wildcards you are
probably knowing from MS-DOS.
@paragraph{}

If you want to get a list of all functions you should enter either
nothing (the default), or ".*", or "?*" (both without the double quotes).
The expression "*" does NOT mean all function. In fact, your entry will be
interpreted as a regular expression.
@paragraph{}

After you have typed the expression and pressed @key{Enter}, you will get
a list of  functions that match the regular expression and for
which debugging information is available.
@paragraph{}

This list is sorted by the name of the function and has three parts:

@format
NAME | RETURN VALUE | FILE
@end format

You can walk throught the list with the cursor keys or the mouse. If you hit
@key{Enter} or double click a function, you will go the the source code
of that function.
@paragraph{}

@node PROJECT
@section Project

Here you can add or remove items to or from your project
@paragraph{}

@subsection Open project
@cindex Open a project
@cindex Creating a new project

Here is the point to open a project. After selecting this menu
item, the file open dialog is opened to select a project. You can type
the name of the project or select one from the list.
@paragraph{}

If you open a project in an other directory than the current, RHIDE will
change the current directory to this directory and then the project
will be opened.
@paragraph{}

If you type here a name of a project, which does not exist, a new one
is created.
@paragraph{}

If no project was opened
and you create a new project,
all open desktop files remain open, but they are not added to
the project.
If a project was opened, it will be automatically closed before the
new project is opened.
@paragraph{}

@subsection Close project
@cindex Close a project

This closes the current opened project and closes all files, which are
on the desktop.
@paragraph{}

@subsection Add item
@cindex Adding a file to the project

A dialog will be opened, from where you can choose your file
to add to your project. If you are in the project window
(@xref{Project window})
you can use the @ikey{Ins,Add a project item} key to activate this function
within the project window.
@paragraph{}

Currently it is impossible to use relative or absolute paths as part
of a project item. If you have your files in several directories, you
have to setup either the search path for source files or you have to create
for each directory a library that can be included in your project.
@paragraph{}

@subsection Delete item
@cindex Remove a file from the project
@cindex Delete a file from the project

This will remove the selected item in the project-window
from your project. If you are in the project window (@xref{Project window})
you can use the @ikey{Del,Remove a project item} key to activate this function.
@paragraph{}

@subsection Local options
@cindex Options for a single file
@cindex Local options for a project item

Here you can give the selected project-item options for
compiling, which will be in effect only for this item. If you are in the
project window (@xref{Project window}) you can use @ikey{Ctrl+O,Local options}
to activate this function.
The options you give here are passed to gcc only, when compiling this file.
For more details see (@xref{Local options for a project item}).
@paragraph{}

@subsection Includes
@cindex Show the includes for a file
@cindex Dependencies for a file

This shows the dependencies for the selected item in the project
window. You can use the hotkey
@ikey{Ctrl+I,Show includes} in the project window.
(@xref{Project window})
@paragraph{}

@subsection Main targetname
@cindex Building an executable
@cindex Building a library
@cindex Changing the name of the library
@cindex Changing the name of the program
@cindex Name of the main target
@cindex Type of the main target
@cindex Main targetname

Here you can change the name of your main target. The main target is either
an executable file or a library. RHIDE selects the type of the main target
from the suffix of this name. If it has no suffix or the suffix @file{.exe},
an executable will be built. If it has the suffix @file{.a}, a library will
be created.
@paragraph{}

@cindex Creating a COFF file
@cindex COFF file, Creating
Remember when you give it no suffix, both, the COFF image and the @file{.exe}
file will created. If it has the @file{.exe} suffix, only the @file{.exe}
file is created.
@paragraph{}

@subsection Primary file
@cindex GPC, --automake

Here you can give the primary source file, when you want to use the
'automake' feature of GPC. If you type a source name here, RHIDE assumes
that your program is written in Pascal and does NOT check any dependencies
of the project, because this is done automatically by GPC with the
@samp{--automake} option.
@paragraph{}

If you don't want to use the 'automake' feature of GPC, even when building
a Pascal program, give here an empty name, which is the default.
@paragraph{}

@subsection Clear dependencies
@cindex Removing the internal dependencies
@cindex Clearing the dependencies

This function removes all internal stored dependencies. The files are not
removed. This is useful when you want to create a makefile
(@xref{Write Makefile}) and you do not want to include  all the absolute
filenames for the dependencies (mostly the include files).
@paragraph{}

This function is a relict from earlyer versions of RHIDE, but I have not
disabled it.
@paragraph{}

@subsection Delete rebuildable files
@cindex Make clear
@cindex Clearing the project
@cindex Removing all targets

This function includes the function of clearing the dependencies
(@xref{Clear dependencies}) and removes in addition to it all the
files, which can be rebuild within RHIDE.
@paragraph{}

@subsection Write Makefile
@cindex Creating a makefile
@cindex Write a makefile
@cindex Makefile

Here you can create a makefile that  contains all the rules to build
the project from the command line without starting RHIDE. For this
you need the GNU make, because the generated makefile uses the features
of GNU make very extensively.
@paragraph{}

If you have used environment variables in your search paths
(@xref{Directories}), these are not expanded in the generated makefile.
But all variables you used will be defined at the beginning of
the makefile with their current value.
@paragraph{}

@section Options

This menu contains many submenus for anything you can customize.
@paragraph{}

@subsection Directories
@cindex Changing the search paths for files

Here you can define all of the paths, where RHIDE and the compilers
finds the needed files and where to store some files.
@paragraph{}

@cindex Environment variables
All the paths you can define in the several entries have the form
of a semicolon separated list of directories, just like your environment
variable %PATH%. You can use forward slashes and back slashes, but they
are all converted to forward slashes by RHIDE. You can also use
environment variables as part of your paths. The syntax of such a variable
is that of a GNU makefile. If you want to use the variable @var{%DJDIR%},
you must type @var{$(DJDIR)}.
@paragraph{}

@subsubsection Include directories
@cindex Include files
@cindex Header files
@cindex Include directories
@cindex Search path for include files

This is the list of directories, where gcc looks for include files and RHIDE
searches in this directory (after looking in the current directory) for
header files.
@paragraph{}

@subsubsection Library directories
@cindex Library search path
@cindex Search path for libraries

This is the list of directories, where gcc looks for libraries when linking.
RHIDE searches in this directories (after looking in the current directory)
for libraries, if you have included them directly as a project item.
@paragraph{}

@subsubsection Object directories
@cindex Object files in a different directory
@cindex Object file search path
@cindex Search path for opbject files

This is the list of directories where RHIDE looks for object files.
If you type here only one directory this has also the effect that
the object files, which are compiled, are stored in this directory.
@paragraph{}

@subsubsection Sources directories
@cindex Source files in a different directory
@cindex Source file search path
@cindex Search path for source files

This is the list of directories, where RHIDE looks for the source files
(after looking in the current directory).
@paragraph{}

@subsection C/C++-Compiler

In this submenu you can change most flags, which have to do when compiling
C or C++ files or better for the options of all the currently supported
compilers.
@paragraph{}

@subsubsection Warnings
@cindex Generating of warnigs
@cindex Supressing of warnings
@cindex Controlling the warnings
@cindex Warnings

This opens a dialog where you can enable or disable most of the
flags for generating or supressing warnings when you compile a
C or C++ file.
(@xref{How to toggle these flags}).
@paragraph{}

For a detailed description of the available flags see
@mxref{Warning Options,,,gcc.inf,gcc}.

@subsubsection Optimizations
@cindex Optimizing the code
@cindex Controlling the optimization of the code

This opens a dialog where you can customize how the compiler optimizes
your code.
(@xref{How to toggle these flags}).
@paragraph{}

For a detailed description of the available flags see
@mxref{Optimize Options,,,gcc.inf,gcc}.

@subsubsection Debugging
@cindex Debugging info

This opens a dialog where you can customize the amount of debugging information
the compiler should include in object files.
(@xref{How to toggle these flags}).
@paragraph{}

For a detailed description of the available flags see
@mxref{Debugging Options,,,gcc.inf,gcc}.

@subsubsection C options
@cindex C language specific flags
@cindex Flags for C files

This opens a dialog where you can select flags that are only passed
to gcc  when compiling C files.
(@xref{How to toggle these flags}).
@paragraph{}

For a detailed description of the available flags see
@mxref{C Dialect Options, , ,gcc.inf,gcc}.

@subsubsection CXX options
@cindex CXX options
@cindex Flags for C++ files
@cindex Cplusplus options

This opens a dialog where you can select flags which are only passed
to gcc when compiling C++ files.
(@xref{How to toggle these flags}).
@paragraph{}

For a detailed description of the available flags see
@mxref{C++ Dialect Options,,,gcc.inf,gcc}.

@subsubsection Pascal options
@cindex Pascal options
@cindex Flags for Pascal file

This opens a dialog where you can select flags which are only passed
to gpc  when compiling Pascal files.
(@xref{How to toggle these flags}).
@paragraph{}

For a detailed description of the available flags see
@mxref{Pascal Dialect Options,,,gpc.inf,gpc}.

@subsubsection How to toggle these flags

The options in the dialogs for Warnings, Debugging, C-flags and CXX-Flags
are selected with the cursor-keys or the mouse and are activated or 
deactivated by pressing @ikey{SPACE,Activate a flag} or by double-clicking
with the mouse at the first field of the option. If an option can take an
additional value or string, an inputbox will be opened, and you can type them
there. If the additional value is optional, you can leave this input-box
by pressing @ikey{ESC,Leaving a dialog} or activating the @emph{Cancel} button
and no value, or the previous one will be appended to this option.
@paragraph{}

@subsection Libraries
@cindex Libraries

Here you can tell the linker which libraries will be
linked in your program. At this time the number of additional libraries
is limited to 16. If you need more, you have to type them manually
(@xref{Linker options}).
@paragraph{}
    
In the input-fields of the dialog you only have to type the part of your
library name after @file{lib} and before @file{.a}. Example: If your library
is @file{libtv.a} you have to put only @file{tv} there. You can switch
between the inputlines for the libraries using @ikey{Tab,Next inputline}, or
@key{Down Arrow} (next field), or @ikey{Shift+Tab,Previous inputline}, or
@key{Up Arrow} (previous field). If you have
typed your libraries you can activate or disable them by switching the
checkbox before the name on or off. This is done by pressing @key{Alt} and
the corresponding digit or letter of the checkbox at the same time or by
clicking with the mouse.
@paragraph{}
    
Normally RHIDE checks the types of your source-files and automatically
adds some standard libraries, corresponding to these source-files.
These are for C++ files the library @file{libiostream.a}
@ignore
, for Flex source-files the
library @file{libfl.a}, for Bison source-files the @file{libbison.a}
library
@end ignore
and for Objective C files the @file{libobjc.a} library.
If you want to disable this, deactivate the @emph{Use standard libraries}
checkbox. This adds also the commandline option @var{-nostdlib} to
gcc,
that means, you must give the linker explicit all of the standard
libraries, which you need. This includes the @file{libgcc.a} and
@file{libc.a} libraries. 
@paragraph{}

@subsection Linker options
@cindex Linker options
@cindex Options for the linker

work of the IDE. A dialog will be opened where you can turn on or off
the following options:

@node all dependencies in makefile
@subsubheading all dependencies in makefile
@cindex Creating a makefile
@cindex Dependencies in makefile
When this is enabled, all internally
stored dependencies for a project item are written to the makefile.
(@xref{Write Makefile}). You should disable this option, if you want
to give an other user the makefile of your project, and (s)he has a
different directory structure.
@paragraph{}

(@xref{Preferences})
@paragraph{}

@node create backupfiles
@subsubheading create backupfiles
@cindex Backup files
@cindex Creating backup files
Create backupfiles when saving. When it is enabled, RHIDE creates a backup
of the file to save under the same name as the editing file, but the suffix
is replaced with @file{.bak}
@paragraph{}

(@xref{Preferences})
@paragraph{}

@node syntax highlighting
@subsubheading syntax highlighting
@cindex Syntax highlighting
@cindex Highlighting the syntax
Turn the Syntax highlight on or off. RHIDE automatically checks the suffix
of the editing file to determine the correct syntax highlighting.
Currently this is supported only for C, C++, and Pascal source files.
All other files are not specially highlighted.
@paragraph{}

(@xref{Preferences})
@paragraph{}

@node Use dual display
@subsubheading Use dual display
@cindex Debugging, dual display
@cindex Dual display when debugging
Here is an very powerfull option. If you have installed on your computer
a secondary display (monochrome monitor) in addition to your VGA monitor,
RHIDE can (when this option is enabled) switch to to the dual monitor
for it's output and you can see your program on the normal monitor.
@paragraph{}

If this option is enabled and you have not a secondary monitor installed,
RHIDE will detect this and does not switch to it.
@paragraph{}
@paragraph{}

(@xref{Preferences})

@node No file caching
@subsubheading No file caching
@cindex File caching
@cindex Caching of files
If this option is enabled, RHIDE does not use
the internal caching of information about searching files and
modification times. Use this only if you have problems with the
automatic checking of dependencies, because this slows down RHIDE.

@node 16 background colors
@subsubheading 16 background colors
@cindex Background colors, 16
@cindex Blinking colors
On EGA/VGA video cards it is possible to use 16 background colors instead
of normal 8. This is done by telling the video card how to interpret
the highest bit of the color attribute. If you enable this, you can use
up to 16 background colors, otherwise there are only 8 colors for the
background available. To get blinking foreground colors, you must use a
little trick. Enable at first this option here. Then change  the color
attribute you want to highlight background color you want and then
reset the '16 background colors' option.

@paragraph{}

@node Screen mode
@subsubheading Screen mode
@cindex Video mode
@cindex Text mode
Here
you can select the video mode. If you want to use a video mode
other than  the ones shown, you have to select the @var{User Mode}
mode and type the value of this mode (see in the reference of
your video card) as a decimal or hexadecimal (preceeded by
@code{0x}) number. But
you can use only textmodes (modes with starting video ram address
at @code{0xB800:0000}. For the numbers of the videomodes refer to
the documentation of your video card.
If you type an invalid videomode (RHIDE checks it), the
80x25-Mode will automatically selected.
@paragraph{}

I have tested all available text modes with my
et4000-card, and they work. For some modes, (mostly every
high resolution text mode)
the mouse cursor is shown by my own routine.
That means that you can use the mouse also in the high resolution text
modes.

an integer there

@titem %d?
if you activate this option, you @emph{can} enter
an integer there

@section Help
In this menu you have access to many predefined help entries in
the big helpsystem.

@subsection Help
@cindex Help

This opens the INFO viewer. Many thanks at this point to 
Salvadore Eduardo Tropea (SET). He wrote the very good INFO viewer for
use with RHIDE. This was also the most important reason for me to
write the documentation in Texinfo, because you have now an online help
available with the produced
INFO file @file{rhide.inf}.
@paragraph{}

The help system can be invoked from everywhere by pressing
@ikey{F1,Help}. For help on using the INFO viewer, press
@ikey{F1,Help about the INFO viewer} within the help window.
But the above things work only if you have correctly installed the INFO files
that come with RHIDE.
@paragraph{}

If you have installed the binary archive of RHIDE as described in the
@file{readme.bin}, the INFO files are in @file{%DJDIR%/info}. If you
have not modified your @file{djgpp.env} file, this directory is searched
for the INFO files.
@paragraph{}

But you can put the INFO files in any directory you want, if you add this
directory to the %INFOPATH% variable in your @file{djgpp.env} file in
the section for @file{info}.
@paragraph{}

@cindex How the editor works

This section should describe the work of the editor. But because the editor
is now so complex and not my own work, there is now a separate documentation
for it. Look at

for a detailed and better doc. But you
can read also more from my doc, which describes the most common (for me)
usage of the editor.

Here I describe most of the editor commands. If there is a key command like
@key{Ctrl+Q+Y}, you have to press @key{Ctrl} and @key{Q} simultaneously and
after this press @key{Y}.

when restarting RHIDE.

@section Some hints and problems
@cindex Hints
@cindex Problems

@cindex Single file compiling
@cindex Compile without a project
To compile only a single file, you don't need to include it in a project.
You only have to open it and do a compile. If a file is in your project,
you can compile it, if you are in its editor-window or if you are in the
project-window and this file is selected.
@paragraph{}

Warnings and errors from compiling a file are listed in the message-window.
If there are warnings or errors, you can jump to the corresponding source by
hitting @ikey{ENTER,Select a message} on this message. If this file wasn't already opened,
it will be opened.
@paragraph{}

@subsection Problems with automatic dependencies
@cindex Dependencies, problems with it
@cindex Automatic dependencies, problems with it

Most checking of the dependencies works correctly, but there are some few
situations, where this checking gets confused. The first results in the fact
that I implemented a cache function for getting the modification time
of files, that means, most files are 'stat'ed only once, after starting
RHIDE. But if someone modifies one of the files, which are in the cache,
(this can be an other program, when you run RHIDE in a multitasking
environment, such Windows) or if you run your project and it modifies some
of these files, the internal cache is after this not up to date.
@paragraph{}

Here is an other situation. Your source files are not in the current
directory. You have opened a source file for editing and successfully 
built your project. Now you leave RHIDE, because you want to debug your
program with @file{fsdb}, you copy the source file (in this case it is the
file, which you have opened in the IDE) to the current directoy. Now
you debug it and there are some errors. You restart RHIDE to make the
changes in the file. The previously opened file will be opened automatically
and you edit it. If you do now a @emph{Make}, RHIDE tells you, that your project
is up to date, because it searches for source files at first in the current
directory, and there is the unmodified file.
@paragraph{}

In this chapter I will give you for some special parts a more detailed
description of what they do.
@paragraph{}

@section Project window
@cindex Project window

The project window shows you every file, which you have included in your
project. Most time you work with RHIDE this window should be visible, but
you can also close it (@xref{Close}).
@paragraph{}

@subsection Items of your project

The items in the project window, and therefore also in your project, are
sorted in alphabetical order. This has the effect of faster finding
an item and you can also move the selecting bar to a specified item by
typing the name of this item.
@paragraph{}

@cindex Order of the project items
Normally, the alphabetic order of the project items causes no problems because
the linker searches at first @emph{every} object file for unresolved
symbols before any library. The statement, the the GNU linker is a one pass
linker makes sense only for libraries, because they are checked only once
for unresolved references. That means, if you include libraries in your
project you must know about the order, where this library is put on
the command line when linking your program.
@paragraph{}

If you have problems with that order, or if you really want to have one
object file (or library) before some others, you have to rename them, to
get the right position from the name.
@paragraph{}

@subsection Open a project item

To open an editor window with the selected item press either @key{SPACE} or
@ikey{ENTER,Open a project item}. If here was already a window with this file opened on the
desktop, this window will be selected. This works only if the selected
item has a know suffix (@xref{Known suffixes}). If the selected item is
a project file, that project will be opened with the side effect that
if you close this project, the previous one will be reopened.
@paragraph{}

@subsection Dependencies of project item

If you have compiled a file already in RHIDE, you bring up a list with all
dependencies of that file. In this list the files are show by their
basename followed by the directory and they are also sorted in alphabetical
order. From here you can also open an editor window with the selected
dependency by pressing @key{SPACE} or @ikey{ENTER,Open an include file} on
that item.
@paragraph{}

@subsection Local options for a project item

You can change many options for a project item, which are in effect only
for this file. To do this, hit @ikey{Ctrl+O,Local options} on the selected
item and a dialog is shown, where you can change the options.
@paragraph{}

At this time you can change the following options.

@node Local comandline options
@subsubheading Local comandline options
Here you can give some additional defines
or any other commandline options, when compiling this item.


@node Exclude from link
@subsubheading Exclude from link
This is a switch to tell RHIDE, that this file
should not linked with your program, but it is compiled and it is checked
to determine if your program is up to date.

@node Name of the output file
@subsubheading Name of the output file
Here you can specify an other name as the
compiled file. Put here only the basename of the file (without any
directory)

@node Compiler type
@subsubheading Compiler type
From that list you can select exactly one type of
the compiler, which is used to create your output file. Possible
values are:

@table @samp
@titem Auto
This is the default and should be used in most cases. When
this type is selected, RHIDE selects the correct compiler depending
on the suffixes of your source and output file.

@titem User
If you have any special compiler, which is not known to
RHIDE, to create your output file, you must select this and give
RHIDE also the calling syntax of that compiler (see below)

@titem None
If you don't want to compile this item select this.

@titem GNU C compiler
Tell RHIDE to compile this file like a normal
GNU C source file.

@titem GNU C++ compiler
Tell RHIDE to compile this file like a normal
GNU C++ source file.

@titem GNU assembler
Tell RHIDE to compile this file like a normal
GNU assembler file.

@titem GNU Pascal compiler
Tell RHIDE to compile this file like a normal
GNU Pascal file.

@end table

If you have selected the User compiler type, you have to put in the next
inputline the specs how to call the compiler. This specs can use any
variables that are known to RHIDE (@xref{Builtin variables}) together
with normal text. As an example I show here, how the builtin C compiler
is defined (the backslashes at the end of the lines are used only here
to show, that the line is continued, they are NOT part of the specs):

@format

$(RHIDE_GCC) $(INCLUDE_DIRS) $(C_DEBUG_FLAGS) $(C_OPT_FLAGS) \
$(C_WARN_FLAGS) $(C_C_LANG_FLAGS) $(C_EXTRA_FLAGS) $(LOCAL_OPT) \
-c $(SOURCE_NAME) -o $(OUTFILE)

@end format

@node Error checking
@subsubheading Error checking
Here you can select how  errors or warnings that  are
produced by the compiler, are checked. Possible values are:

@table @samp
@titem Auto
Let RHIDE select the correct way for checking the errors

@titem User
Use your own external program to check the output of the
compiler to @code{stderr}

@titem None
Do not check any errors, assume that the compiler does
it's job every time successfull

@titem builtin C
Check the errors like when compiling a C file

@titem builtin assembler
Check the errors like when copiling an
assembler file

@titem builtin linker
Check the errors like when linking

@titem return value
Determine only if the compiling was successfull
or not by checking the return value of the compiler (zero for
success)

@end table

@node Error program
@subsubheading Error program
If you have selected above the User error checking,
type here the program, which should check for errors and/or warnings.
What the external error checking program should do:

@itemize @minus
@item The program must take a filename as argument, which contain the
output to stderr from the compiler (Error and warning messages)

@item The program has to write to stdout the Warnings, Errors or
messages in a special format.

@table @samp
@titem Errors
A line that starts with the string "!Error" (without the
double quotes) optionally follwed by "!File" and a filename
in single quotes and "!Line" and a line number.
The next line contain the error text.
Example:

@format

!Error!File'test.c'!line17
This is a sample error message

@end format

This means, that in file 'test.c' at line 17 has an error occoured
with the description 'This is a sample error message'

@titem Warnings
Warnings have the same format, except that !Error is replaced by
!Warning.

@titem Any other line
is treated as a simple message optionally preceeded
by !File and !Line.

@end table

@end itemize

@section Builtin compiler specs
RHIDE uses for compiling, linking, and the other stages of generating
a file also specs, like you can change in the local options for a
project item (@xref{Local options}). Here the specs, which are used
currently:

@table @asis
@titem $(RHIDE_COMPILE_C)
For compiling C source files

@titem $(RHIDE_COMPILE_CC)
For compiling C++ source files

@titem $(RHIDE_COMPILE_ASM)
For compiling assembler source files

@titem $(RHIDE_COMPILE_PASCAL)
For compiling pascal source files

@titem $(RHIDE_COMPILE_OBJC)
For compiling objective C source files

@titem $(RHIDE_COMPILE_LINK)
For linking

@titem $(RHIDE_COMPILE_LINK_PASCAL)
For linking when the project contain pascal source files

@titem $(RHIDE_COMPILE_LINK_PASCAL_AUTOMAKE)
This spec is used only, when you have set the (@xref{Primary file}), to
tell RHIDE, not to check for dependencies but to use the 'automake'
feature of GPC.

@titem $(RHIDE_COMPILE_ARCHIVE)
For creating a library

@titem $(RHIDE_FSDB)
For calling fsdb.

@titem $(RHIDE_GDB)
For calling gdb.

@titem $(RHIDE_GPROF)
For calling gprof.

@titem $(RHIDE_GREP)
For calling grep.

@end table
@paragraph{}

All of these specs have a default contentents in RHIDE, but they can be
overwritten by setting the environment variable with the same name and
any other contents.
@paragraph{}

@section Builtin variables
This section describe, which variables can be used within RHIDE to get
values from some of the configurations, which you have made inside RHIDE.
@paragraph{}

All of these variables are refernced by a name enclosed in parantheses
preceeded by a dollar sign. Example: @samp{$(RHIDE_GCC)}. You can overwrite any
of the following variables, if you define in your environment the same
variable with any contents you want.
@paragraph{}

When RHIDE tries to get the contents of such a variable, it searches at first
if it is found in it's internal database. If it was not found, the environment
is checked for such a variable and if that fails, the resulting value is
the variable itself.
@paragraph{}

In addition to the use of variables, RHIDE has a limited ability of
using string manipulating functions. I have implemented some of the
functions, which are available with GNU make. They have the same name
and should work exactly like the GNU make counterpart.
@paragraph{}

@table @samp
@titem $(strip arg)
This function removes any leading and trailing whitespace and converts
all multispaces to single spaces from the (whitespace separated list)
@samp{arg}.

@ifset html
@titem $(addsuffix arg1\\\,arg2)
@end ifset
@ifclear html
@titem $(addsuffix arg1,arg2)
@end ifclear
These functions append on each argument from the whitespace separated list
@samp{arg2} the string @samp{arg1}.

@ifset html
@titem $(addprefix arg1\\\,arg2)
@end ifset
@ifclear html
@titem $(addprefix arg1,arg2)
@end ifclear
This is the same as
@ifset html
@samp{$(addsuffix arg1\,arg2)},
@end ifset
@ifclear html
@samp{$(addsuffix arg1,arg2)},
@end ifclear
except that it puts
the string @samp{arg1} before each argument from @samp{arg2}.

@titem $(notdir arg)
This removes any directory part from the argument @samp{arg}.

@titem $(dir)
This extracts only the directory part from the argument @samp{arg}. If there
was not directory in @samp{arg}, an empty string is returned. (The directory
contains also the drive letter, if there was one)

@ifset html
@titem $(subst arg1\\\,arg2\\\,arg3)
@end ifset
@ifclear html
@titem $(subst arg1,arg2,arg3)
@end ifclear
This replaces every occoureance of @samp{arg1} in @samp{arg3} with
@samp{arg2}

@section Change the defaults of RHIDE
@cindex Other compilers
@cindex Configuring RHIDE

If you have special wishes for compiling your source files, you can
configure for RHIDE mostly everything. For adding support for other
than the builtin known file types (@xref{Builtin variables}). If you
want to change the behaviour of RHIDE for compiling all the known
file types you should know at first really what you do. If you think,
this is a good idea or if you only want only check if it works you can
do it.
@paragraph{}

Before RHIDE compiles any file (this includes also linking and building
a library) it searches the environment for a variable after the following
scheme: When compiling a file with suffix @file{.c} to a file with
suffix @file{.o} RHIDE checks for the variable $(RHIDE_COMPILE.c.o). If
this variable is defined the contents of this variable is taken as the
compile spec.
@paragraph{}

If you want to change the specs for linking you must take as destiniation
suffix @file{.exe} or @file{.} and as source suffix the suffix of
your object files. Example:

@format
$(RHIDE_COMPILE.o.)
@end format
@paragraph{}

@section Message window
@cindex Message window

This window shows every time you compile a file the resulting messages, which
gcc produces. These messages were converted in a special format to show
them in the window. Some of the messages contain a file eventually combined
with a line number. If you press @ikey{ENTER,Jump to the source line} on such
a message, the corresponding source line in the file will be highlighted
and the window with this file will be selected. If this file is not already
on the dektop, it will be opened.
@paragraph{}

If the file, to which the messages refer, is already in the foreground you can
see the selected source line for your messages directly on the screen.
@paragraph{}

@section Syntax highlighting
@cindex Syntax highlighting
@cindex Highlight the syntax

Syntax highlighting is now supported directly by the editor. It should
work in mostly every situation for all the supported types. Currently
(in RHIDE) only the C/C++ style syntax highlight and the Pascal style
syntax highlight are supported.
@paragraph{}

With which style a file is highlighted is choosen by RHIDE by checking
the suffix of the file and determining the file type from that suffix.
(@xref{Known suffixes})
@paragraph{}

@section Checking the dependencies
@cindex Checking dependencies
@cindex Dependencies, checking

This is one of the main parts of RHIDE. To speed up the work, I have added
a cache for checking the modification time of a file and for finding
a file (computing the full name of a file). But sometimes the data in 
the cache isn't valid, especialy when running under Windows. If you see
this, you can clear the cache by leaving RHIDE and starting again.
@paragraph{}

If you didn't any special things but have problems with it, please
run RHIDE with the @samp{-df} switch and try to find out, where the
problem is and post it to me so I can fix it.
@paragraph{}

@section What is Turbo Vision
@cindex Turbo Vision

The Turbo Vision library is part of Turbo C++ version 3.1. I have ported
this library to use with DJGPP because I think it is the most powerful
text windowing library, which is available for MS-DOS. With the help of
this library you can write front end application which looks very well
and the interface is easy to use.
@paragraph{}

The Turbo Vision library is not only a window based text user interface,
it is also a very good event handling mechanism. It supports the use of
the mouse and keyboard with the ability of defining and using of hotkeys,
that means, you can assign to some keys or combinations of keys, which
function should be executed.
@paragraph{}

The main parts of an application, which is using this library, are the
desktop, the menu bar and the statusline. The menu bar is usualy shown
as the topmost line of the screen. There are shown the main parts of
the pull down menus, from where you can select the most functions, which
are implemented in an application.
@paragraph{}

To use the menu you can use the mouse as well the keyboard. With the mouse
you can click every where on a menu entry and the corresponding function
will be executed. There are some different actions, which a menu entry can
have. At first some of them, these are for example all the entries in the
menu bar, open a submenu with more menu entries which are related to
the name of this main entry. And the others, most in such a submenu, execute
a definite function of the application.
@paragraph{}

With the keyboard you can walk through the menu very simply. To activate the
menu bar, you have to press @ikey{F10,Activate menu bar}. In the pull down
menus you can use the cursor keys to move the highlighted bar up and down
and with the cursor right and left keys you can switch to next or previous
menu. With the @ikey{ENTER,Select a menu entry} key you activate the function,
which corresponds to this entry. If this was a submenu, which is indicated
with a symbol like a small right arrow, this will be opened.
@paragraph{}

If you walk through the menu with the cursor keys or the mouse (hold the left
mouse button down and move the mouse) in the statusline will be shown for
each entry a short hint for the function of this menu entry.
@paragraph{}

@section How the dialogs work
@cindex Using the dialog
@cindex Dialog function keys

In a dialog, like the file open dialog, are many things which you can select
or where you can type in some data. At first some general functions. If you
press @ikey{ESC,Leaving a dialog}, the dialog will be closed and nothing will
be changed. The same can be done with the mouse by clicking on the close
symbol (this is the small symbol on upper left frame of the dialog).
@paragraph{}

In the next paragraphs I will describe the most used elements of a dialog.
For selecting each element of a dialog you can use the @key{Tab} key to
select the next element in the dialog or the @key{Shift+Tab} key, to select
the previous element.
@paragraph

@cindex Button
A button is a rectangle with some text on it. If you activate such a button a
specified action is executed. To select a button you can use the @key{Tab}
key, until the button is special highlighted and press then
@ikey{ENTER,Activate a button}. Or most times a character of the text on this
button has a different color. So you can press @key{Alt+} this charcter to
activate the button. With the mouse you can simply click on a button to
activate it.
@paragraph{}

@cindex Lists
@cindex Listbox
A listbox is a collection of some strings in one or more columns and rows as
needed. The project window (@xref{Project window}) is such a listbox with
the names of the project items. You can use the cursor keys to move the
focus bar in the list, or if it is a sorted listbox, you can also type
some characters and the focus will moved to the item, which starts with
this characters. To select a item in a list box, press @key{SPACE} or
@ikey{ENTER,Select a item in a listbox} or double click with mouse on it.
@paragraph{}

@cindex Input line
In an input line you can type some text which can be edited with the usual
editing keys.
@paragraph{}

@cindex Checkbox
A checkbox is a collection of options, which can be turned on or off.
Each option has in front of it a small indicator, if it is turned on
(an X is shown) or not (the X is not shown). To toggle such an option,
use the cursor keys to move the focus to the option you want and press
@ikey{SPACE,Toggle an option}. If a character in an optionstring is
highlighted you can press this key and the option will be turned on or
off or click with the mouse on the option.
@paragraph{}

@cindex Radiobuttons
Radiobuttons are similar to checkboxes, but there you can select only
one of all the shown options.
@paragraph{}

@section Defining macros
@cindex Macros
@cindex Pseudo Macros

Please look for a detailed documentation here:
@extref{Pseudo Macros,Documentation about Pseudo Macros,editor.inf,SET's editor,editor.html}
@paragraph{}

@section The INFO Viewer
@cindex Info Viewer
@cindex Helpsystem

The integrated helpsystem of RHIDE is based on the INFO
Viewer written by @SET{}. It gives you access to all the INFO
files which you have installed in the correct directories like
for @file{info.exe}.
@paragraph{}

To get help about the INFO Viewer hit @ikey{F1,Help about the INFO Viewer}
when the helpwindow is opened or follow this link
@mxref{Top,,,infview.inf,The Info Viewer}.
@paragraph{}

In addition to getting help with this system you can also copy text
from the helpscreen to the clippboard. This is usefull if you want
for instance to copy an example from the libc reference in your
program. This feature is not so powerfull like in the editor, but
it is good enough. To mark some text use the @key{Shift} and
cursor keys and copy the selected text with @key{Ctrl+Ins} to
the clipboard.
@paragraph{}

@cindex Context help
In RHIDE you have also the possiblility to get help about a specific
function. Currently this works only for functions, which are documneted
in the libc reference. For doing this, move the cursor to the function
and hit @ikey{Ctrl+F1,Context help} or click with the right button of
the mouse on that word.
@paragraph{}

@chapter Debugging with RHIDE

For debugging your programs you need now no external debugger, because
RHIDE has one integrated. The integrated debugger is not code which
I have written, but it is GDB 4.16, which is linked in RHIDE.
@paragraph{}

Because RHIDE uses a special method to communicated with GDB it is currently
not possible to use all of the features, which GDB has. I have implemented
at this time the most important functions, which are needed to debug your
program. So it is not possible to give GDB the same commands as when
running GDB standalone. That means, if you need any very special feature
of GDB you have to run GDB.
@paragraph{}

The integrated debugger is a real source level debugger like GDB. If
you step trough your program you will see every time exactly where
in the sources you are. But to use the aibility to debug your
program needs, that you have compiled your source files with
debugging information and this symbols must not be stripped
from the executable.
@paragraph

@section Limitations of the integrated debugger

Because the integrated debugger is GDB, you will have all the limitations
which GDB has in addition to well known DJGPP and/or MS-DOS limitations.
Here is a (not completely) list of known misfeatures:

@itemize @bullet
@item Signals are not handled every time correct by distinguishing between
the debuggee and RHIDE

@item Remote debugging is NOT supported

@item Debugging of graphic programs may work or not depending on
the software you are using. Currently only the VESA modes and the
standard VGA graphic modes are supported.

@item When using the integrated debugger under
Windows 3.1x (in Windows 95 there is no such limitation) the number
of breakpoints is limited to 3, because you can use there only hardware
breakpoints. The i386 supports only 4 hardware breakpoints and 1 is needed
for internal use.
This is a
common problem for all DJGPP debuggers. (Try to use FSDB with more than
3 breakpoints under Windows 3.1x)

@item Sometimes the source line, which is shown by RHIDE in assuming
that the execution is there, is not correct. But this is NOT a bug of
RHIDE and NOT of GDB. This is a bug in GCC which produces wrong line
number information in the object files. Here is a very simple test
program, with which you can see this problem.

@example
/* This is an example, that gcc produces wrong line number
   information for code which is optimized out. (compile this
   with -O) */

int a = 1;
int b = 2;

int main()

@section Dual display debugging
@cindex Dual display
RHIDE supports now also to use an installed dual display. This is when
you have installed in addition to your VGA card a monochrome display
card together with a monitor. RHIDE checks this by asking the BIOS
if it is present and if this is true and the option is enabled
(@xref{Preferences}) then RHIDE switches automatically to
the secondary display when debugging and your program will run
on the primary display.
@paragraph{}

With this debugging technique you will get the best debugging results
especially when debugging graphics programs.
@paragraph{}

To use the dual display with RHGDB use the @samp{-D} switch for
RHGDB.
@paragraph{}

@section Using the integrated debugger

If you are familiar with Borland's debugger, you will see, that most of
the function of that debaugger are implemented in the same or in a
similar way (this includes the key bindings).
@paragraph{}

@subsection Stepping trough the source code

For stepping trough your code, there are three ways. This is at first
the Step-function @key{F8}. With this you execute a complete source
line. If there is a function call at the current execution point, this
function is called without debugging it. This technique is the same
like the @samp{next}-command from GDB.
@paragraph{}

The next way is the Trace-function.
It does the same like the Step-function @key{f7}, except if there is a function
call at the current execution point, you will go into this function, if there
is debugging information for that function available.
This technique is the same like the @samp{step}-command from GDB.
@paragraph{}

And the third way is the Goto-Cursor-function. For this, move the cursor
to the line in yur source code and press @key{F4}. Now the execution of
your program is continued until it comes to that line. Sometimes you will
get an error message, that for the specified line is no code generated.
This comes from the optimization of yor code by GCC. In this case try
a line below or above.
@paragraph{}

@subsection Evaluating the contents of variables

You can evaluate also the the contents of variables, when your program
has been started. For this you can press @key{Ctrl+F4} and you will
see a dialog, where you can type in the expression to evaluate, a line
with the result and a line, where you can give the expression a new
value. If you have pressed this in an editor window, RHIDE tries to find
the a word under the cursor and copies this as default in the
expression-inputline. To get the contents of this expression you have
to press the @emph{Evaluate}-button.
@paragraph{}

If the expression could not be evaluated so it is shown in the result line.
For the exact syntax of getting the contents of an expression
@mxref{Expressions,,,gdb.inf,gdb}. You can also show the value of the
expression in several formats @mxref{Output Formats,,,gdb.inf,gdb}.
@paragraph{}

In addition to the functionallity of the Borland debuggers, GDB (and
of course also RHIDE) can evaluate the result of function calls. If
you have for example in your debugged program a function
@example
int foo(int arg1)
@{
/* do something and return a value */
@}
@end example
defined, you can type in the expression inputline
@format
foo(16)
@end format
and you will get as result, what the function would return, if it is
called with the argument @code{16}. As arguments you can also use
any known variable or complex expressions.
@paragraph{}

A known limitation is, that the expressions are NOT checked for validity.
That means, you can produce any exception there, which will terminate
your program. As an example type in the expression inputline
@format
3/0
@end format
And, of course, you cannot assign to a function call a new value.
@paragraph{}

@cindex Builtin calculator
As an special side effect you can use this also as a calculator. You
can evaluate any trivial or complex expression and this is also available,
if you didn't started the integrated debugger.
@paragraph{}

@subsection Watching the contents of variables
In addition to a single look at the contents of a variable, you can
add the variable to a list which is updated after each debugger
step and is shown in the watching window. For this function you
can use the hotkey @ikey{Ctrl+F7,Add to the watches}.
@paragraph{}

Within the watch window you can press @key{Enter} on an expression
to change that expression (NOT the contents of that expression)
or you can press @ikey{Del,Remove from the watches} to remove the variable
from the watch window.
@paragraph{}

@section Problems with C++ programs
Because GDB cannot handle correct C++ debugging information you will
have many problems when debugging C++ programs to get the contents
of a variable when it is a member of a class. Because GDB does not
detect, that your program is a C++ program, it sees it as a normal
C program and so GDB does nothing know about classes and all what
have to do with it.
@paragraph{}

For accessing the member of a baseclass you must do some tricks. Let me explain
it on an example:

@example
class A
@{
public:
  int a;
@};

class B : public A
@{
public:
  void test();
@};

void B::test()
@{
  fprintf(stdout,"%d\n",a);
@}

@end example

If you debug the program in the function @code{B::test()} and you
want to get the contents of the member @code{a}, you have to access
it with @code{this->A.a} !!! That means: At first you must access
all members with the implicit @code{this} variable and at second
you must give all baseclasses until that, where the member was
declared.
@paragraph{}

@section Using Breakpoints
Breakpoints are a very usefull thing when debugging a program. You
can set a breakpont at any location of your program and run it. It
will be automatically stopped, if the program execution reaches the
breakpoint.

@subsection Setting a breakpoint
For setting a breakpoint there are two different ways. The first is
by setting a breakpoint at any line by pressing
@ikey{Ctrk+F8,Breakpoint at a line}. You will see, that there is a
breakpoint set, that this line is shown in an other color. If
you hit @ikey{Ctrl+F8,Breakpoint delete} on a line, which
has already a breakpoint, the breakpoint at this line
is removed.
@paragraph{}

@subsection Modifying and setting a breakpoint
The second way is by setting a breakpoint with the breakpoint dialog
which is selectable only from the menu. There you will see any breakpoint
for your program. These breakpoints can be modified now in many things.
In this dialog you can enable/disable a breakpoint. This is not the
same as deleting and resetting it. If you disable a brekpoint, it is
stored internal but it is not used. If you enable it again all the sttings
for that breakpoint, which you have already made, are remembered.
@paragraph{}

In the breakpoint dialog you can also set or delete a breakpoint with
the given buttons. If you want to set a new breakpoint, use the
New-Button. Then you will get a dialog which you also get when you
press the Modify-Button. In this dialog you can change many things of
the breakpoint.
@paragraph{}

In this dialog is the only point for setting a breakpoint at a
specified function. For doing this you must set at first the type
of the breakpoint to Function. Then you can type in the function inputline
the name of the function or hit @ikey{Ctrl+F1,List of functions}
to get a list of functions which are available from where you can select
one with @key{Enter}.
@paragraph{}

For setting a breakpoint at a specified line, set the breakpoint type
to Line and type in the filename and the linenumber.
@paragraph{}

The next what you can modify on a breakpoint is a condition. That means
that the breakpoint should stop your program only, if the condition
is true. Write the condition in the programming language of your
source file and you can use any accessable variable and you can call
also functions of the debugged program. For other information about the
syntax @mxref{Conditions,,,gdb.inf,gdb}.
@paragraph{}

And at last you can give your breakpoints also a count. A breakpoint count
is a number, how often this breakpoint is ignored. That means, if you type
there for example 10, then the RHIDE stops the execution of the program
only, if it comes to that point the 10th time. WARNING: This count is
set by RHIDE only once. After the breakpoint is realy hit, from now on
the breakpoint stops your program every time, the breakpoint is reached.
@paragraph{}


@subsection Problems with breakpoints
Currently there is a big problem, when you have set a breakpoint at a
line (not at a function) of your program and you edit now the source
code. If you insert or delete some lines the breakpoints, which are
set at lines after or at the modified lines are NOT updated to the correct
line number.

@chapter Debugging with RHGDB
In addition to RHIDE, which has an integrated debugger, there is also
a standalone debugger called RHGDB. (The name comes from my initials
and GDB)
@paragraph{}

RHGDB has the same aibilities like RHIDE for debugging your program. But
it has no editor. The source files are shown in read only windows where
you can move the curser and other things (except editing) like in RHIDE.
@paragraph{}

The menu tree is anolog to RHIDE but (of course) it has not all the menu
entries of RHIDE, becuse RHGDB should be used only for debugging and
nothing else.
@paragraph{}

I have written it to debug DJGPP programs, for which there is no
RHIDE project file available but the program has debugging information
and, if you are small of memory, it is much smaller than RHIDE.
@paragraph{}

The syntax for using RHGDB is very simple. Run it with your program
as the first argument followed by any argument, which should be passed
to your program.
@paragraph{}

RHGDB saves and reads the options from files with the suffix @file{.rgd}.
This done automatacly when you run RHGDB with your program as argument
by searching a file with the same basename of your program and the suffix
@file{.rgd} and in this file the options are also automaticaly stored,
when you exit RHGDB.
@paragraph{}

Alternatively you can also save/read the options from within RHIDE
by selecting the corresponding menu entries from the Options menu.
@paragraph{}

@cindex Dual display with RHGDB
To use the the "Dual display debugging" feature of RHGDB you must
give on commandline the @samp{-D} switch.
@paragraph{}

@chapter Some FAQs

@quest{I have enabled the @samp{Use tabs} option, but if I move
the cursor through that tab, it seems, that RHIDE uses spaces}
@cindex Cursor through tabs

@ans{}This behaviour cannot (currently) not changed. Even when you
have enabled the use of real tabs (charcaters with the code 9), the
cursor is moved like as there are spaces.
@paragraph{}

@quest{If I write an ALL UPPERCASE TEXT while pressing down the shift
key and typing the characters, the SPACE key is not recognized}
@cindex Shift+Space
@cindex Change the keybindings

@ans{} This correct, because RHIDE uses as default the key combination
@key{Shift+Space} for executing a Pseudo Macro (@xref{Defining macros}).
If you don't like this behaviour, or when you also want to change some
other keybindings, please read in the documentation about the editor,
how you can configure the keybindings.
@paragraph{}

@extref{Keyboard,Documentation about the keyboard,editor.inf,SET's editor,editor.html}
@paragraph{}

@quest{Are there any sample project files, to show how RHIDE works?}
@cindex Sample projects
@cindex RHIDE project files
@cindex Rebuilding RHIDE

@ans{}The sources of RHIDE include many project files to rebuild
at least RHIDE with itself and many others.
@paragraph{}

@quest{I have written some libraries. How can I use them in a project?}

@quest{How I can use a library, which I got?}

@cindex Use of libraries
@cindex Libraries in a project
@ans{} There are some different ways to do this. On the one side you can
include them directly in the project with the
@emph{Add to project item} function (@xref{Add item}). But if they are
not in the current directory, you must also set the library search path
to the directory, where they are. (@xref{Library directories}). The other
variant is to include them in the list of libraries. (@xref{Libraries})
@paragraph{}

If this library is created with RHIDE, that means you have a project
file for building this library you can also simply include that
project file in you project. For examples look at the RHIDE sources
in the project file for RHIDE.
@paragraph{}

@quest{I have a directory, where all my include files are. Can I setup
RHIDE to have this directory every time in the include search path, when
creating a new project?}

@quest{I prefer the 80x28 video mode over the default 80x25 mode. How I
can turn this mode on by default for all newly created project files?}

@cindex Default project file
@ans{} You can create a default project file. From this file RHIDE reads
all the options, if it creates a new project. The default project must
have the same basename as the executable of RHIDE and must be located in
the same directory.
@paragraph{}

The creation of such a default project file is very simple. Change to the
directory, where @file{rhide.exe} is located and run there
@format
rhide rhide
@end format

Now make any changes in the options which you want to have as default for
all new created projects. This includes also settings in the various
search paths. If you are ready, exit RHIDE and this project file will
be your default project file.
@paragraph{}

@quest{I know, that I can create a default project file. Can I create and use
more than one?}

@cindex Default project file, more than one
@cindex Different name for RHIDE
@ans{}Since DJGPP supports a quasi-Unix-like link for executables, you can
create such a link also for RHIDE. As an example I will create a link to
@file{rhide.exe} with the name @file{myrhide.exe}. At first I have to
create the new file.
@display
stubify -g myrhide.exe
@end display
Now I must tell @file{myrhide.exe} which program it really should run.
@display
stubedit myrhide.exe runfile=rhide
@end display
Thats all. Or, if you have installed the GNU fileutils, you can use also
now the @file{ln.exe} program to create the link:
@display
ln -s rhide.exe myrhide.exe
@end display
@paragraph{}

@quest{I don't want to type every time I start RHIDE
the commandline @var{-L de}
to use the german user interface. Is there any better way?}

@cindex Default language
@cindex Language, setting the default
@ans{} Create an environment variable @var{LANGUAGE} with your preferred
language like
@display
set LANGUAGE=de
@end display
and your problem is solved.
@paragraph{}

@quest{I have 4 Mb RAM in my computer and every time, when I compile large
files with optimizations enabled, my hard disk is working very hard.}

@ans{}Buy more RAM!
@paragraph{}

@quest{I heard something about a newer version RHIDE. From where I can get
exact information about this?}

@cindex Latest version of RHIDE
@cindex RHIDE, latest version
@ans{} See @www{at the RHIDE home page,www.tu-chemnitz.de/~rho/rhide.html}.
This page contains the latest news and the latest version of RHIDE.
@paragraph{}

@quest{I have a lot of money and don't know what to do with it. Can you
help me?}

@cindex Donations to the author
@ans{} Send it to me, so I can spend more time for developing
RHIDE. My Address is:

@paragraph{}

@quest{I think, I found a bug in RHIDE. How can I report it?}

@cindex Bug, reporting it
@cindex Reporting bugs
@ans{}At first try for your own to solve the problem by checking the
documentation.
See at @RHIDEHOME{}, if this problem was already reported by other
users. As the next ask the problem in the news group
@news{comp.os.msdos.djgpp}, because there may be some other people
with the same problem, and they can give you an answer or I, because
I read this group also.
@paragraph{}

If this don't help you, do the following:

@quotation
Try to reproduce the error with the smallest possible project or
source file. Run RHIDE with all debugging options enabled and redirect
the printed output to a file. (@xref{Debugging RHIDE}) Send me this file
and a detailed as possible description of the problem and include in
your report the exact version of RHIDE you are using.
@paragraph{}

The exact version is shown in the About-Dialog and means the version
number together with the build date.
