TM - Tiny eMacs
TM is a DOS text editor with a fair amount of Emacs-like behavior in an executable smaller than 4096 bytes.
See tm.txt for documentation (however, it is best viewed using tm.com).
Project Organization
TM source files:
- init.8 -- defines variables; must be named first on the command line
- tm.8 -- bulk of editing code
- key.8 -- macro handling
- dos.8 -- file IO
- srch.8 -- incremental search & replace
- mem.8 -- memory and buffer managemnt; must be last on the command line
Other sources of note:
-
ztrim.8 : A program that trims the zero-initialized variables from the start of a COM program.
-
other/scan.8 : A test program that accepts keyboards input and displays the keycode representation that TM uses internally in its function binding tables.
TM is written in A86 assembly language.
Environment
./Makefile is intended to be run from a POSIX-ish environment. It invokes
dosbox to build TM, assuming that the DOSBOX configuration will place A86
in the path.
