med, Micro Emacs in D

This is my version of MicroEmacs, based on the public domain version by Dave Conroy. I like it because it is small, fast, easilly customizable, and it ports readilly to whatever machine I need to use it on. It's written in the D programming language.

It currently works on Windows and Linux.

Glossary

• dot current cursor position
• mark start of a region
• minibuffer text entry box used for entering file names and search strings
• region text between "dot" and "mark"
• Regular Expressions

Notes

• ^[ also works as Esc.
• Names without a keybinding can't be accessed, but they can be called if the keybindings in main.c are updated.
• Prefixing a command with ^U enables a count to be entered, which executes the command count times.
• Pressing ^X, AltF, or Esc and then pausing will bring up a menu.
• The right mouse button will bring up a menu.
• The left mouse button can be used for setting the dot, marking regions, and adjusting window sizes.
• The minibuffer has a small history buffer, accessible with the uparrow key.
• On Win32, by clicking on the title bar, then select [Edit], you can access the Windows clipboard. This is very handy for cutting/pasting text from another window or the web browser.

Bugs

• Some of the keybindings make no sense.
• The Alt function key sequences don't work on Win32.
• The control numeric pad sequences don't work on Linux.
• The colors can't be modified on any but the DOS version.
• The process functionality is flaky.
• For some reason, the mouse in the Win32 version doesn't work on Win2000, but does on WinNT.
