Originally created by @remorses on GitHub (Nov 19, 2025).
Original GitHub issue: https://github.com/anomalyco/opentui/issues/328

Currently opencode has no way to show colors for commands outputs because we do not have ANSI highlighting support

My idea for implementing this would be to

Parse ANSI into an array of colored segments
Convert this array into a list of TextChunk like we do now for tree sitter highlighting

I guess ANSI parsing would need to be fast so implemented in the Zig side

What do you think @kommander?

I think opencode would solve that with something like #166, but probably using libghostty-vt.

I also found this project which would be a good start: https://github.com/coder/ghostty-web

It uses libghostty to render a terminal in the browser

Yeah that's basically what #166 does for opentui, but also providing it as a TerminalRenderable. So that but libghostty would be the way to go imo.

I found another example https://github.com/kcosr/pty-to-html/blob/main/src/main.zig

I can open a PR to add support for this, but without any stdin handling, just rendering the ansi into styled text without keeping any state

It would depend on some ghostty code. what do you think?

I created a package to use ghostty-vt to turn ANSI into opentui renderables here
