Flow Control: a programmer's text editor

This is my Zig text editor. It is very much a work-in-progress, but far enough along that I am daily driving it.

Build with the provided zig wrapper:

./zig build -Doptimize=ReleaseFast

The zig wrapper just fetches a known good version of zig nightly and places it in the .cache directory. Or use your own version of zig.

Run with:

zig-out/bin/flow

Place it in your path for convenient access.

See --help for full command line.

requirements:

A modern terminal with 24bit color and kitty keyboard protocol support (kitty and ghostty are the only recommended terminals at this time)
NerdFonts support
Linux (other OSes will come eventually, patches welcome!)

features:

fast TUI interface. no user interaction should take longer than one frame (6ms) (even debug builds)
tree sitter based syntax highlighting
multi cursor editing support
first class mouse support (yes, even with a scrollbar that actually works properly!)
vscode compatible keybindings (thanks to kitty keyboard protocol)
vim compatible keybindings (at least the basics, more to come)
good unicode support
hybrid rope/piece-table buffer for fast loading, saving and editing with hundreds of cursors
theme support (compatible with vscode themes via the flow-themes project)
infinite undo/redo (at least until you run out of ram)
stuff I've forgotten to mention...
