## Summary
- add `--login` and `--free` flags to cli help
- handle `--login` and `--free` logic in cli
- factor out redeem flow into `maybeRedeemCredits`
- call new helper from login callback
Prior to this PR, I would frequently see glyphs from previous frames
"bleed" through like this:
I think this was due to two issues (now addressed in this PR):
* We were not making use of `ratatui::widgets::Clear` to clear out the
buffer before drawing into it.
* To calculate the `width` used with `wrapped_line_count_for_cell()`, we
were not accounting for the scrollbar.
* Now we calculate `effective_width` using
`inner.width.saturating_sub(1)` where the `1` is for the scrollbar.
* We compute `text_area` using `effective_with` and pass the `text_area`
to `paragraph.render()`.
* We eliminate the conditional `needs_scrollbar` check and always call
`render(Scrollbar)`
I suspect this bug was introduced in
https://github.com/openai/codex/pull/937, though I did not try to
verify: I'm just happy that it appears to be fixed!
Previously, if the first user message was sent with the command
invocation, e.g.:
```
$ cargo run --bin codex 'hello'
```
Then the user message was added as the first entry in the history and
then `is_first_event` would be `false` here:
031df77dfb/codex-rs/tui/src/conversation_history_widget.rs (L178-L179)
which would prevent the "welcome" message with things like the the model
version from displaying.
The fix in this PR is twofold:
* Reorganize the logic so the `ChatWidget` constructor stores
`initial_user_message` rather than sending it right away. Now inside
`handle_codex_event()`, it waits for the `SessionConfigured` event and
sends the `initial_user_message`, if it exists.
* In `conversation_history_widget.rs`, `add_session_info()` checks to
see whether a `WelcomeMessage` exists in the history when determining
the value of `has_welcome_message`. By construction, we expect that
`WelcomeMessage` is always the first message (in which case the existing
`let is_first_event = self.entries.is_empty();` logic would be sound),
but we decide to be extra defensive in case an `EventMsg::Error` is
processed before `EventMsg::SessionConfigured`.
When running `npm test` on `codex-cli`, the test
`agent-cancel-prev-response.test.ts` logs a significant body of text to
console for no obvious reason.
This is not helpful, as it makes test logs messy and far longer.
This change deletes the `console.log(...)` that produces the behavior.
I did a bit of research to understand why I could not use my mouse to
drag to select text to copy to the clipboard in iTerm.
Apparently https://github.com/openai/codex/pull/641 to enable mousewheel
scrolling broke this functionality. It seems that, unless we put in a
bit of effort, we can have drag-to-select or scrolling, but not both.
Though if you know the trick to hold down `Option` will dragging with
the mouse in iTerm, you can probably get by with this. (I did not know
about this option prior to researching this issue.)
Nevertheless, users may still prefer to disable mouse capture
altogether, so this PR introduces:
* the ability to set `tui.disable_mouse_capture = true` in `config.toml`
to disable mouse capture
* a new command, `/toggle-mouse-mode` to toggle mouse capture
