• In tuicr, can I compose a PR comment in nvim to get vim keybindings and Markdown rendering?

  • AI Answer

    • Short answer: Partially, via a config flag — but there is no way to shell out to a real external nvim process (and no Markdown preview) for the comment box specifically.
    • tuicr's comment box has a comment_vim config option (default false); when set (or toggled at runtime with :vim / :set vim!), the box switches to edtui modal editing — hjkl, w/b/e, dd/D/ciw/x, u/Ctrl-r, visual v+y/d/p, :w/:q-style save/cancel. That is a real Vim-modal emulation built into the comment box, not nvim itself — no plugins, no LSP, no Markdown rendering. Verified in agavra/tuicr: docs/CONFIG.md, docs/KEYBINDINGS.md ("Comment mode"), and src/app/comment_vim.rs.
    • Separately, tuicr does shell out to $EDITOR (see src/editor.rs, :edit command in docs/KEYBINDINGS.md) — but only to open the focused diff file in your real editor, not the comment text box.
    • tuicr/Wishlist already tracks the closest related idea — editing the PR description in $EDITOR — following the same "hand off larger text to an external editor" shape that could extend to comments.
    • Workaround today: enable comment_vim = true for Vim-modal editing inside tuicr, or draft the comment in real nvim and paste the finished Markdown into the comment box for full editor ergonomics plus live Markdown preview (e.g. via a plugin like glow or an in-editor Markdown renderer).
