MEdit

MEdit

MEdit was the apogee of my DOS programming. I always wanted to write a text editor - and I succeeded. Well, I haven't comletely finished it... After I switched from DOS to Linux, I also switched from MEdit to VIM.

Features

• Lithuanian language support: fonts and keyboard input
• Macro language (keys, commands, loops, conditions, command definition, etc. Almost a programming language, if it only had variables...)
• Customizable: colors, key mappings, other options
• Syntax highlight (Pascal, C, C++, Assembler, .BAT files, CONFIG.SYS, .INI files, MEdit macro files, TvHc help source files)
• Line drawing
• Text formatting, word wrap, etc.
• Regular expression search (looks very powerful to me)
• Built-in calculator (Real/Dec/Hex/Bin/Oct, 28 operations, 28 functions, just type an expression)
• Multiple Undo/Redo
• Can share Windows clipboard
• Two types of blocks (normal and column)
• Block operations:
  • Sorting
  • Indent/unindent
  • Filling with character/duplicating first line
  • Aligning parts of lines
  • Drawing a border around block
  • Enumerating block lines
  • Summing (sum, count, min, max, average)
  • etc.
• Context sensitive online help, multi-windowing, mouse support, any standard/non standard text mode support, etc. - nothing very special

Restrictions

• A maximum of 32766 lines per file
• A maximum of 255 characters per line
• All opened files must fit into computer memory (EMS/XMS)
• TAB characters aren't special - except that you may expand them to corresponding number of spaces
• Syntax highlight is not too fast. Also, yet there is no way of specifying custom file formats for highlighting.

System Requirements

• 286 or newer CPU
• At least 2 megabytes of free extended memory
• MS-DOS 3.0 or later
• Some hard disk space (a megabyte should be really enough)

Download

• MEdit 2.00 Lithuanian version (253K)
• MEdit 2.00 English version (212K)
• Borland DPMI runtime files (required; 63K)

Unfortunatelly, source is not available — I'd like to, but MEdit's sources include a modified copy of Borland Turbo Vision source code, which I cannot distribute.

Future

The work is stalled on version 2.04 alpha:

• Mail reader
• Window minimization. When loading desktop minimized windows are not loaded automatically, thus saving time. They are actually loaded only when you restore them
• Extended 101 key keyboard support
• More complex macro conditions (conditional operators allowed)
• New key binding method: each kind of window (editor/calc/mailbox/letter/icon) has its own keymap.
• A primitive macro disassembling

Unfortunately, I don't think this version will ever be finished. :(
