This is an absolutely minimal termcap / terminfo library using a single hardcoded database to support only one terminal type.
It was written to support an emscripten build of zsh targetting only xterm.js as the terminal. However, it could also be useful for other minimal situations or cases where you want to avoid building the whole of ncurses.
A basic Makefile is included and running make should be sufficient on most
platforms. This builds a static library. To build the library with emscripten,
use:
emmake make CFLAGS="-O1"
When building software against libtiti, you may need to override some configure variables, e.g.
./configure ac_cv_func_setupterm="no" ac_cv_func_initscr=no --with-term-lib=titi
The library does not extend to the curses interfaces so will not be usable for any programs that use these. The empty curses.h include file may help if configure scripts look for it.
Included is a zsh script named mkdb which can be used to generate a C include
file containing terminal definitions for $TERM. The output is sorted by the
termcap key so the termcap interfaces can use a binary search while the
terminfo interfaces search sequentially. Swapping this or creating a sorted
index would be a trivial option if needed.
The included file is based on definitions for xterm-256color but changed to reflect actual behaviour of xterm.js.
For emscripten, xterm-pty is needed to monkey
patch further terminal interfaces such as ioctl() calls.
Some tests of tparm() can be run with make test. To run the same tests
against the system libraries, use make check.
