issy is a minimal console text editor written in Zig with zero
external dependencies. Its defining idea is that code on screen
should look like text on a printed page: a centered code column on
wide terminals, restrained luminance-driven syntax highlighting
instead of rainbow colors, and a soft right margin that stops long
lines from running into the terminal edge.

It ships with a gap buffer for text storage, syntax highlighting for
20 languages (including TeX/LaTeX), multi-cursor editing,
incremental search, undo/redo, and path auto-completion in the open
prompt. It can also export the current buffer to a real PDF 1.4 file
with TTF/OTF font embedding via a hand-rolled writer, with no
external print system involved.
