  Permission is granted to copy and distribute modified versions of this manual under the conditions for verbatim copying, provided that the entire resulting derived work is distributed under the terms of a permission notice identical to this one.

  People who helped me develop the editor:

  - `Robert Höhne` (with some base routines, a lot of patchs and reports)
  - `Molnar Laszlo` (with tests and a lot of ideas)
  - `Marek Habersack` (with tests and a lot of ideas)
  The editor is freeware, but the souce-code of this editor is copyrighthed by Salvador Eduardo Tropea. If you want to include the editor in your application, using the whole code or only a part contact at first me

  This editor is included in the Robert Höhne's RHIDE as a replacement for the original TVision's editor class.

  ### 1.1 What is SET's Editor?

  SET's editor is an editor designed to be used by programmers; the main target of the editor is C and C++ code but Pascal and Clipper are supported too.

  The editor was designed to be very similar to the DOS standard editors for C, especially to the Borland's IDE editor. The editor supports a lot of WordStar style commands plus some CUA commands, so if you used any editor that uses these kinds of commands you'll find my editor very familiar. On the other hand if you never used a DOS editor, especially if you use VI on UNIX machines you'll feel lost. You can configure the keyboard but this feature is relative limited. See How to configure the keyboard .

  ### 1.2 Requirements

  For now I only plan to distribute my editor inside of RHIDE requirements are the requirements of RHIDE.

  ## 2. Available commands

  In this section I will explain the features of the editor and the default configuration for the keyboard. If you want to change some assigment of a key consult See How to configure the keyboard .

  Read the conventions topic first to understand my way of indicating keystrokes.

  In the description of each command I'll include the internal name used by the editor because this name is needed to configure the keyboard.

- Conventions--
- Cursor movement--
- Insert and Delete--
- Blocks--
- Pseudo Macros--
- Miscellaneous--

  ### 2.1 Conventions

  I'll use some conventions when talking about the keystrokes needed to trigger some command. So here is what I use:

  The key named Ctrl or Control is represented as ^; this key doesn't have any effect used alone inside of the editor so the ^ symbol will be used only in conjuntion with the name of some key indicating that you must press the two keys at the same time; for example: ^A is Ctrl and A at the same time. When I say "at the same time" that means: press Ctrl, hold it, and press the other key; that's the reason to put A after Ctrl.

  To indicate a sequence of keystrokes I'll use a - to separate the keys; for example ^K-B is Ctrl and K at the same time, and then press B; of course release ^K first.

  To indicate keys pressed at the same time other than ^x I'll use the +; for example: Shift+^Insert is the three keys at the same time!.

  I don't think that you are stupid; the editor is written for programmers, but I'll wanted to make that clear to avoid problems ;-).

  When you are in insert mode all the typed characters are inserted in the text, but when the isert mode is off the typed characters replaces the old text. The editor starts with insert mode on. You can quickly know the mode by the cursor shapem when the insert mode is on the cursor is only a line, but when is off the cursor is a block.

- Block modes--
- Selecting with the mouse or Shift--
- Indentation--
- Rectangular Blocks--

  #### 2.4.1 Block modes

  There are two block modes, one is the mode that the old editor of RHIDE used this mode is used in CUA programs, and the other is called Persistent Blocks.

  In the normal mode each time you select a block and then insert any thing on it (with `cmbPaste` or typing anything) the selected block is deleted and is replaced by the new text.

  In persistent blocks the selection is not replaced and is not loosed when you move the cursor, from here comes the name "Persistent", in this mode you can use `cmbMoveBlock` and `cmbCopyBlock` without using the Clipboard, in adition you can apply indentations to the block (See Indentation ), search only inside it, etc, that's makes this mode much more powerful than the former. If you really like to replace the selected text by the selection of the Clipboard, that's the default behaviour of the first mode, you can use the `cmbReplaceSelect` command to achieve the same in the Persistent Blocks mode.

  #### 2.4.2 Selecting with the mouse or Shift

  The described commands for select a block, `cmbStartSelect` and `cmbEndSelect`, are good but not so quick, there are another ways to make that.

- Using the mouse--
- Using the Shift key--

  #### 2.4.2.1 Using the mouse

  Using the mouse you only need to point the start place, hold the left button pressed and move the mouse to the end point of your block.

  To select a word with the mouse just double click on it.

  #### 2.4.2.2 Using the Shift key

  Using the shift key you only need to move the cursor to the start point, hold Shift pressed and move the cursor to the end point with any of the available See Cursor movement commands.

  #### 2.4.3 Indentation

  You can indent or unindent a block of text using various commands, but you must keep in mind that by now the editor is limited in the following: If you are using See Real Tabs to indent your text don't mix the tabs with spaces and if you are using spaces to indent don't mix it with real tabs.

  - Indent block one position adding an space
    - Editor command: `cmbIndentBlkOne`
    - Key: `^K-I`
    - Alternative: `Shift+^I`
  - Unindent block one character - not an x position
    - Editor command: `cmbUnIndentBlkOne`
    - Key: `^K-U`
    - Alternative: `Shift+^U`
  - Indent block
    - Editor command: `cmbIndentBlk`
    - Key: `^K-Tab`
  - Unindent block
    - Editor command: `cmbUnIndentBlk`
    - Key: `^K-Shift+Tab`
  - Smart Indent block
    - Editor command: `cmbSmartIndent`
    - Key: `^Tab`
  - Smart Unindent block
    - Editor command: `cmbSmartUnIndent`
    - Key: `Shift+^Tab`
  `cmbUnIndentBlkOne` unindents deleting one char at the start of the line so if the line is indented with tabs the line will retroced one tab.

  `cmbIndentBlk` acts according to the mode, if you are using See Real Tabs , the editor will put one tab in each line, if you aren't using tabs the editor will operate the Tab command on the first line and then will use this amount of indentation in the rest of the block.

  `cmbUnIndentBlk` acts according to the mode too, in See Real Tabs mode is just like `cmbUnIndentBlkOne` deleting one tab but if you don't use tabs the editor uses Backspace on the first used column of the first line of the block and unindents the resulting amount all the block.

  `cmbSmartIndent` and `cmbSmartUnIndent` indents taking as reference the { } pair where the block is, for example:

             {
           line1
                line2
              line3
             }

  After indenting a block that contains line1 to line3 is:

             {
              line1
              line2
              line3
             }

  The indentation is made with spaces.

  #### 2.4.4 Rectangular Blocks

  The editor includes a mode where you can select a rectangular portion of the text and copy, cut, clear, paste, move, etc this region. This tool is very useful for modifications on columns.

  Attention! the selected area is based on the X,Y coordinates, for this reason if you insert lines before the bottom of the rectangle the area won't be moved. I don't plan to move the area by now because that takes some CPU and I think that this selection is made just before using it. So don't report that like a bug is that the way that works.

  - Set beginning of block
    - Editor command: `cmbSelRectStart`
    - Key: `^K-Shift+B`
  - Set end of block
    - Editor command: `cmbSelRectEnd`
    - Key: `^K-Shift+K`
  - Hide/Show block
    - Editor command: `cmbSelRectHide`
    - Key: `^K-Shift+H`
  - Delete block and copy it to an special Clipboard
    - Editor command: `cmbSelRectCut`
    - Key: `^K-ShiftT`
  - Move block
    - Editor command: `cmbSelRectMove`
    - Key: `^K+Shift+V`
  - Copy to special Clipboard
    - Editor command: `cmbSelRectCopy`
    - Key: `^K-Shift+C`
  - Delete block
    - Editor command: `cmbSelRectDel`
    - Key: `^K-Shift+L`
  - Paste from special Clipboard
    - Editor command: `cmbSelRectPaste`
    - Key: `^K-Shift+P`

  ### 2.5 Pseudo Macros

  This feature is very useful to save some keystrokes, with this feature you can create a lot of shortcuts to make your life easiest.

- Please enlight me - what is that?--
- How can I customize that?--

  #### 2.5.1 Please enlight me - what is that?

  So now, What's a Pseudo Macro?, It's like a macro but is triggered but two things: one the text behine the cursor and two the ^Space convination.

  And What's the result?, the result is customizable, but by default there are some predefined behaviours for example, type in a new window the following two letter: #i and the press ^Space ...

  Surprised?, I bet, you got: #include <.h> and the cursor just in the right place to write the name of the header.

  Now write the famous stdio word, press End, then Enter twice and now write the following two letters: ma and then ^Space ...

  I bet this time you predicted better what will happend so you aren't so surprised ;-), anyways Surprise!, now type pr and the magic keys and .... printf(""); appears, to end the happy history now type Hello world!, that's all; you wrote the hello world program at a very good speed.

  Now you know what I mean when I say pseudo-macros.

  #### 2.5.2 How can I customize that?

  Is very easy there is a file called `pmacros.txt` in the same directory where you started the editor, this file contains the definitions for each pseudo macro, you can define up to 32 pseudo macros (Please tell me if that isn't enough I can sacrify some time to make it dinamically expandable).

  Important: If you are using RHIDE consult the RHIDE documentation to know where is stored the `pmacros.txt` file.

  The pmacros.txt file is a very good example and is self-explained but I'll include here one example.

      Trigger: "i("
      Mode: 0,1,0,1,0
       "if (@0)\n"
       "  {@1\n"
         "}\n"
       "\belse\n"
       "  {@2\n"
         "}"

  The Trigger keyword defines the two letter behine the cursor that will trigger the pseudo macro.

  The Mode keyword indicates the mode that the editor will use when inserting the text. The modes are:

  - Overwrite See Overwrite
  - Autoindent See Autoindent
  - Use Tabs See Real Tabs
  - Persistent blocks See Block modes
  - Intelligent C indent See Intelligent C indent
  Each mode can be 0 or 1. The editor will return to the original mode after expanding the pseudo macro. In this case the macro is expanded in the No overwrite, autoindent, don't use See Real Tabs , the blocks are persistent and don't be smart when indenting mode.

  The rest is the code to insert surrounded by ". You can use \b to indicate backspace, \n for newline and \\ to indicate a simple \. If you want to insert a @ you have to type it twice @@, because this character has a special meaning (see below).

  After the insertion the cursor is positioned in the place marked with @0, don't forget to signal this point or the cursor will positioned at the beggining of the file, the places marked with @1, @2 and @3 are saved in the markers 7, 8 and 9.

  ## 3. Keyboard

  The editor uses the scancodes of the keys to trigger the different commands, you can reconfigure wich key triggers some command. In addition some non US keyboards can mess the commands so you could need to configure the editor for your keyboard.

- How to configure the keyboard--
- A program to find the scancodes--

  ### 3.1 How to configure the keyboard

  There are three associated files with the keyboard: `keybind.cc`, `keybind.h` and `keybind.txt`.

  The `keybind.h` file contains the scancode number for each key and the number for each command, this file is included in `keybind.cc`. If your keyboard have a different assigment you can modify the scancodes in this file, for example: The german keyboards have the following sequence QWERTZ instead of the more common QWERTY, so each time you press ^Z you won't get the function of ^Z, but ^Y instead. Somebody can live with it, but is fixable. To fix this problem you must correct the scancode of the Z key in keybind.h, of course that this affects to ^Y too. That's only an example, the most common problem is with the symbols like {, }, [, etc. If you don't know how to find the scancode of a key take this link See A program to find the scancodes .

  The `keybind.cc` file is a C++ file but you don't need to compile it and link with the editor, you only need to preprocess it (I used this methode to save the time needed to make a parser ;-).

  To convert this file into a `keybind.txt` file use:

  cpp keybind.cpp > keybind.txt

  Where cpp is the C++ preprocessor. You can use any of the comment systems available in C++ inside the file. I guess that you have cpp, but if not you can use another C++ preprocessor or even Clipper using the /P switch.

  There are 7 sections in the file, each section is the keyboard translation under certain situation. The sections are:

  - NORMAL The normal case.
  - SHIFT Shift plus a key.
  - CONTROL Control plus a key.
  - SHIFT_CONTROL Shift plus control plus a key (all at the same time).
  - QUICK A key after ^Q or wherever you defined as `cmbCtrlQ`.
  - BLOCK A key after ^K or wherever you defined as `cmbCtrlK`.
  - BLOCK_SHIFT A key plus shift after ^K or wherever you defined as `cmbCtrlK`.
  In each section you must put the keyboards and the command asociated to it. Use the following syntax: Scan_Code = Command Not all the scan codes are available, for example you can't put: RSHIFT = xxxxx Look the keybind.h to see the scan codes labels and the available commands. Important Notes: I) The new assignments are mixed with the original assignments, so if you want to eliminate an old key combination you *must* assign a `cmbNoCommand` to this key, for example is you wish eliminate the BACKSPACE key and use the ^O instead you must: a) put `BACKSPACE = cmbNoCommand` in the NORMAL section. b) put `O = cmbBackSpace` in the CONTROL section, If you only put the b) you'll not eliminate the BACKSPACE key.

  II) If some thing is wrong in the `KEYBIND.TXT` file the program will inform the error, the line number is for the `KEYBIND.TXT` and not for `KEYBIND.CPP` (sorry some day I'll fix this). To continue the execution press any key and then enter.

  III) You can repeat an assignment, the last win:

           BACKSPACE = cmbNoCommand
           BACKSPACE = cmbBackSpace

  The first is ignored

  ### 3.2 A program to find the scancodes

  The author of the following program is Robert Höhne:

      #include
      #include

      #ifdef __GNUC__
      #include

  ## 4. Editing Modes

  The editor have 9 settings that controls the edition and the aspect of the editor. Not all can be controlled by RHIDE Beta 6 release 22/10, and I don't know if all the settings will be supported in the 1.0 release so if you don't find some setting in RHIDE and you feel that setting is really needed contact me.

  The settings are:

- Overwrite--
- Autoindent--
- Real Tabs--
- Persistent Blocks--
- Intelligent C indent--
- Column cursor--
- Row cursor--
- Match pair highlight--
- Syntax Highlight--

  ### 4.1 Overwrite

  This setting controls if the typed characters are inserted in the buffer or if the typed characters replaces the original ones, see See Insert and Delete for a detailed explanation.

  ### 4.2 Autoindent

  This setting controls what happend when you press `ENTER`, if this setting is off the cursor goes to the column 1 of a new inserted line. If the mode is on the editor will try to keep the indentation of the code inserting spaces.

  ### 4.3 Real Tabs

  This setting controls what happend when you press `TAB`, if this setting is on the editor will insert an ASCII 9 in this place.

  An ASCII 9 is a TAB, that means that the width of this char is enough to move the cursor to the next tabulator column. In the editor the tabulator columns are equidistant and the positions are controled by the Tab Size value.

  If this setting is off the editor won't put any ASCII 9 in your text, instead the editor will insert enough spaces to move the cursor to the next tabulator, but if the cursor is positioned on the first character of the line the editor will insert spaces to move this position to the next hole in the line over the line where you are. Confused?, sorry for my english, an example will clarify that:

  This is a line over the line where you are

  That's the line where the cursor is, at column one.

  After pressing TAB you'll get:

  This is a line over the line where you are

  That's the line where the cursor is, at column one.

  Now can ask, why this? Is that useful?, the answer is that's very useful to keep your code indented, experiment using that under a line with if, for, etc.

  Another thing controlled by this setting is the behaviour of the `Backspace` key, when the setting is on the key is just 'delete the character at the left of the cursor' but when the setting is off this key is the 'Unindent' key.

  The editor is much more coherent when you choose to use TABs or not use tabs, if you mess the two things you'll get some unexpected things, specially in the indentation of the blocks.

  Is better is you ever works in a file without tabs and with this setting of, then you'll get much from the editor.

  Now you can say: But I really need tabs because I'm editing a make file! or because I'll send the file using an ultra slow link and I want the compression granted by the tabs. In these cases you can first expand all tabs, then work without real tabs and at the final of your work compact all possible spaces and generate a file with all the tabs that you need see the See Miscellaneous section.

  ### 4.4 Persistent Blocks

  This setting controls the behaviour of the selected area.

  See the chapter See Block modes for a detailed explanation.

  ### 4.5 Intelligent C indent

  This mode was designed to be used in joint with the Pseudo Macros (See Pseudo Macros ) and the Real Tabs mode in off to achieve an easy way to indent the code making a better work than the Autoindent mode.

  In this mode the spaces inserted after pressing `ENTER` depends on the first word in the last line, for example, if you have:

           if (a==b)_

  With the cursor in the '_' position and press `ENTER` you'll get:

           if (a==b)
             _

  Now you can do two things, 1) press space and write the code that will be executed by the if, or 2) if this a multiline code press { and `ENTER`, in the last case you'll get:

           if (a==b)
             {
              _

  Now type your first line of code, press `ENTER`, write your next line, press `ENTER` again and then Backspace:

           if (a==b)
             {
              1st line;
              2nd line;
             _

  Now type } and press `ENTER` one more time:

           if (a==b)
             {
              1st line;
              2nd line;
             }
           _

  As you can see the code is perfectly aligned without a significant work from your part.

  I tried to make this mode as smart as possible, but needs more work, if you have suggestions contact me.

  Another important thing is that this indentation have a personal style, mine style ;-), so may be you don't like it. If that's your case you can do the following things:

  - Use another way of indentation offered by the editor, for example, turn on the Real Tabs mode and indent with tabs.
  - Customize the pmacros.txt file (See Pseudo Macros ), actually this file is coherent with this mode.
  - The editor isn't configurable like Emacs or Brief using a language, but is writed in C++ and chances that you know C++ are over the 90% so contact me and I'll help you to write the routines that you need to get an indentation in your own style :-).

- Can you explain to me more about the behavior of this mode?--
- Do you have more examples?--

  #### 4.5.1 Can you explain to me more about the behavior of this mode?

  I'll try to describe the behaviour of the mode:

  Each time you press `ENTER` the editor inserts a '\r\n' string in your text, after that the editor searchs one line located above the new line that have at least one character inside. This line is taked as reference, the editor analizes this line searching for:

  - The first non blank character on this line.
  - The first word on this line.
  - The first parethesis.
  - The balance of parenthesis on the line.
  - The last non-blank and non-comment character in the line.
  Now, if the line contains { at the start the editor goes to the first column after the {.

  If the line contains } at the start the editor will go to the same column of the } and then will perform a `Backspace`, is the See Real Tabs mode is off that's an unindent.

  If the line starts with a C++ comment the effect is the same as in See Autoindent .

  If the line starts with a C comment the editor will try to skip the comment and analize the rest of the line, but if the comment doesn't end on this line the editor will go to the column where the / is.

  If the line starts with / the editor goes to this column.

  If the line have more ( than ) the editor will go to the column of the first non-blank after the first (.

  If the line have more ) than ( the editor will search the line where the number of parenthesis is balanced, then will analize this line, if the whole line still generating an unbalanced situation the editor will go to the first used column in the line that was found at first time. But if this line lets all balanced the editor will take the first word on the line and will use it as reference.

  At last, and according to the word founded, the editor will use this word as reference. The editor recognises the following keywords:

  - do: +2, no if ;
  - if: +2, no if ;
  - for: +3, no if ;
  - else: +2
  - case: +5
  - while: +2, no if ;
  - switch: +2
  - break: unindent
  - return: unindent
  - default: +5
  The numbers are how much spaces are added with refernce to the first letter of the word. When 'no if ;' is specified means that if the line ends with a semicolon the editor will make the same as See Autoindent . The unindent is performed with `Backspace`.

  Seasick? take a look at: See Do you have more examples? .

  Note: Some of these features was added in v0.2.14 of the editor based on a suggestion of about of the behaviour of the mode on line like this 'printf("Num: %d",' and the rest of the parameters in the next line.

  #### 4.5.2 Do you have more examples?

  Well here are some examples, I used some strange convention, is like this: if I say 'type a[ENTER]{' is type the a letter, then press `ENTER` and finally press the { key.

  Example 1: (Is similar to the explained before but is to show the convention)

           Type:
           if (a==1)[ENTER]{[ENTER]a=2;[ENTER]b=3;[ENTER][BACKSPACE]}[ENTER]

           You'll get:

           if (a==1)
             {
              a=2;
              b=3;
             }
           [<--- cursor here]

  Example 2: A switch/case example

           Type:
           switch(a)[ENTER]{[ENTER]case 1:[ENTER]a=2;[ENTER]b=3;[ENTER]break;
           [ENTER]case 2:[ENTER]b=5;[ENTER]break;[ENTER][BACKSPACE]}[ENTER]

           You'll get:

           switch(a)
             {
              case 1:
                   a=2;
                   b=3;
                   break;
              case 2:
                   b=5;
                   break;
             }
           [<--- cursor here]

  Example 3: A call to a function that takes a lot of parameters

           Type:
           printf([SPACE]"Num: %d",[ENTER]a[SPACE]);[ENTER]

           You'll get:

           printf( "Num: %d",
                   a );
           [<--- cursor here]

  Example 4: A lot of parethesis

           Type:
           if[SPACE]([SPACE](a==1)[SPACE]||[ENTER](b==2)[SPACE]||[ENTER]
           c[SPACE])[ENTER]

           You'll get:

           if ( (a==1) ||
                (b==2) ||
                c )
             [<--- cursor here]

  Example 5: Comment trying to interfer part 1

           Type:
           /*-a-*/for[SPACE](x=1;x;--x)[ENTER]

           You'll get:

           /*-a-*/for (x=1;x;--x)
                     [<--- cursor here]

  Example 6: Comment trying to interfer part 2

           Type:
           for[SPACE](x=1;x;--x);[SPACE]//-b[ENTER]

           You'll get:

           for (x=1;x;--x); //-b
           [<--- cursor here]

  Note: Of course you can full the editor but as you can see is relative smart ;-).

  ### 4.6 Column cursor

  This setting enables an strange feature of the editor, when this mode is on the column where the cursor is is highlithed. This feature is very good to check if some part of your code is aligned.

  If you like this mode but is very uncomfortable to be used all the time contact me and if I get enough feedback I'll put this thing in a key to be turned on/off quickly.

  ### 4.7 Row cursor

  This setting is similar to the See Column cursor but acts on the row where the cursor is. If you enable the two modes you'll get a cross on the screen showing where the cursor is.

  ### 4.8 Match pair highlight

  This mode acts showing the pairs of (/), [/] and {/} on the fly. Each time you type one of these symbols the editor will search the matching pair, if the editor finds it and the match is on the screen both will be highlithed, if the match is outside the screen the editor will inform the position on the status line, and if there is no match the editor will inform the situation in the status line too.

  That's very usefull when you are typing complex parenthesis expressions or a very nested code. You can use it in joint with the `cmbSearchStart`, `cmbSearchEnd`, `cmbSearchOpPar`, `cmbSearchClPar`, `cmbSearchOpCor` and `cmbSearchClCor` commands (See Miscellaneous ).

  ### 4.9 Syntax Highlight

  The editor can make highlight the syntax of your code, the available modes are:

  - No highlight, all the code is with the same color.
  - C/C++ Highlight.
  - Pascal Highlight.
  - Clipper Highlight.
  The kind of highlight is choosed automatically in RHIDE using the extention of the file.

  The C/C++ highlight was designed for the GNU C compiler.

  The Pascal highlight was designed for the GNU Pascal compiler.

  The Clipper highlight was designed for the CA-Clipper 5 compiler.
