What the API should look like? Which features?
I was thinking of something like this:
* term_ function prefix
* first parameter is the term context
* non blocking io (ie. returns when there's nothing to process)
* use a dirty flag on glyph (or even on lines) to speed up drawing
* scrollback buffer, by popular demand
/* usage example */
term_t* t = term_new(width, height, "/bin/sh");
while(1) {
/* non blocking behaviour */
flag = term_update(t);
/* content of the screen changed */
if(flag & DIRTY)
draw_update(t);
/* bell received */
if(flag & BELL)
beep();
/* title changed */
if(flag & TITLE)
set_title(t->title);
/* cursor moved (we have to remove the old one and draw the new one) */
if(flag & CURSOR)
redraw_cursor();
/* shell exited */
if(flag & DEAD)
die("argh");
if(key_pressed())
term_write(t, key);
if(window_resize())
term_resize(t, new_width, new_height)
/* ... */
}
Do selection-type actions have their place in the lib? Is the
selection per terminal? If I select a chunk of text before the screen
scrolls, do I keep the selected text and scroll the selection with it,
or do I keep the selection position and update the selection buffer?
