Over the last few weeks I've hacked together a partial APL
implementation, for use as a way of specifying lists of numbers etc.
when passing commands between computers implementing a large distributed
system. For test purposes I've compiled it on Linux as a command-line
app and am using FPC's keyboard unit to implement a layout similar to
http://www.aplusdev.org/keyboard.html, with Alt as meta and Esc to go
into composition mode (use cursor keys to move between the glyphs on
each key). Internal storage is in widestrings, external files etc. UTF-8.
I now want to move the parser and evaluator into an LCL-based app, which
will ideally allow at least partial editing of APL-style expressions
rather than reading everything from configuration files.
What is the situation with LCL editing components, Synedit, Cmdline and
so on? Is there a single underlying keyboard component, or at least a
uniform interface?
In short, where do I start? :-)
On Windows you'd write an IME (Input Method Editor), that allows to
compose strings from keystrokes. Don't beat me - I only know that
something like that exists ;-)
The display should not be a problem. AFAIR is the APL charset part of
Unicode, so that you can use SynEdit. Write an APL syntax highlighter
for it, if you like.
Commandlines? Perhaps using the IME, provided that you can tell the
console to use it ;-)
