codex - 💡(How to fix) Fix Vim composer mode: support inner-word text objects (`ciw`, `diw`, `yiw`) [5 comments, 2 participants]

What variant of Codex are you using?

CLI / TUI

What feature would you like to see?

Now that Vim composer mode has landed, it would be useful to support common inner-word text objects in the composer:

• diw: delete inner word
• ciw: change inner word and enter insert mode
• yiw: yank inner word

These are common Vim muscle-memory commands and fill a small gap in the existing composer Vim mode rather than adding a new mode.

Additional information

The existing Vim composer mode supports normal/insert mode and d/y operator flows. Inner-word text objects make those flows feel much closer to expected Vim behavior for prompt editing.

I have a small focused patch with tests that adds these commands in codex-rs/tui/src/bottom_pane/textarea.rs. If this is something maintainers would be open to, I would be happy to open a PR.
