What
- Show compact elapsed time in the TUI status indicator: Xs, MmSSs,
HhMMmSSs.
- Add private helper fmt_elapsed_compact with a unit test.
Why
- Seconds‑only becomes hard to read during longer runs; minutes/hours
improve clarity without extra noise.
How
- Implemented in codex-rs/tui/src/status_indicator_widget.rs only.
- The helper is used when rendering the existing “Working/Thinking”
timer.
- No changes to codex-common::elapsed::format_duration or other crates.
Scope/Impact
- TUI‑only; no public API changes; minimal risk.
- Snapshot tests should remain unchanged (most show “0s”).
Before/After
- Working (65s • Esc to interrupt) → Working (1m05s • Esc to interrupt)
- Working (3723s • …) → Working (1h02m03s • …)
Tests
- Unit: fmt_elapsed_compact_formats_seconds_minutes_hours.
- Local checks: cargo fmt --all, cargo clippy -p codex-tui -- -D
warnings, cargo test -p codex-tui.
Notes
- Open to adjusting the exact format or moving the helper if maintainers
prefer a shared location.

i'm not yet convinced i have the best heuristics for what to highlight,
but this feels like a useful step towards something a bit easier to
read, esp. when the model is producing large commands.

also a fairly significant refactor of our line wrapping logic.
Summary:
- pause the status timer while waiting on approval modals
- expose deterministic pause/resume helpers to avoid sleep-based tests
- simplify bottom pane timer handling now that the widget owns the clock
#### Summary
- render the edit queued message shortcut with the ⌥ modifier on macOS
builds
- add a helper for status indicator snapshot suffixes
- record macOS-specific snapshots for the status indicator widget
before:
```
$ time cargo test -p codex-tui -q
[...]
cargo test -p codex-tui -q 39.89s user 10.77s system 98% cpu 51.328 total
```
after:
```
$ time cargo test -p codex-tui -q
[...]
cargo test -p codex-tui -q 1.37s user 0.64s system 29% cpu 6.699 total
```
the major offenders were the textarea fuzz test and the custom_terminal
doctests. (i think the doctests were being recompiled every time which
made them extra slow?)
this is in preparation for adding more separate "modes" to the tui, in
particular, a "transcript mode" to view a full history once #2316 lands.
1. split apart "tui events" from "app events".
2. remove onboarding-related events from AppEvent.
3. move several general drawing tools out of App and into a new Tui
class
instead of each shimmer needing to have its own animation thread, have
render_ref schedule a new frame if it wants one and coalesce to the
earliest next frame. this also makes the animations
frame-timing-independent, based on start time instead of frame count.
## Summary
- allow Esc to interrupt the current session when a task is running
- document Esc as an interrupt key in status indicator
## Testing
- `just fmt`
- `just fix` *(fails: E0658 `let` expressions in this position are
unstable)*
- `cargo test --all-features` *(fails: E0658 `let` expressions in this
position are unstable)*

## Summary
- add a pulsing dot loader before the shimmering `Working` label in the
status indicator widget and include a small test asserting the spinner
character is rendered
- also fix a small bug in the ran command header by adding a space
between the ⚡ and `Ran command`

Stream models thoughts and responses instead of waiting for the whole
thing to come through. Very rough right now, but I'm making the risk call to push through.
Simplify and improve many UI elements.
* Remove all-around borders in most places. These interact badly with
terminal resizing and look heavy. Prefer left-side-only borders.
* Make the viewport adjust to the size of its contents.
* <kbd>/</kbd> and <kbd>@</kbd> autocomplete boxes appear below the
prompt, instead of above it.
* Restyle the keyboard shortcut hints & move them to the left.
* Restyle the approval dialog.
* Use synchronized rendering to avoid flashing during rerenders.

This update replaces the previous ratatui history widget with an
append-only log so that the terminal can handle text selection and
scrolling. It also disables streaming responses, which we'll do our best
to bring back in a later PR. It also adds a small summary of token use
after the TUI exits.
Moving to Rust 1.87 introduced a clippy warning that
`SendError<AppEvent>` was too large.
In practice, the only thing we ever did when we got this error was log
it (if the mspc channel is closed, then the app is likely shutting down
or something, so there's not much to do...), so this finally motivated
me to introduce `AppEventSender`, which wraps
`std::sync::mpsc::Sender<AppEvent>` with a `send()` method that invokes
`send()` on the underlying `Sender` and logs an `Err` if it gets one.
This greatly simplifies the code, as many functions that previously
returned `Result<(), SendError<AppEvent>>` now return `()`, so we don't
have to propagate an `Err` all over the place that we don't really
handle, anyway.
This also makes it so we can upgrade to Rust 1.87 in CI.
`BottomPane` was getting a bit unwieldy because it maintained a
`PaneState` enum with three variants and many of its methods had `match`
statements to handle each variant. To replace the enum, this PR:
* Introduces a `trait BottomPaneView` that has two implementations:
`StatusIndicatorView` and `ApprovalModalView`.
* Migrates `PaneState::TextInput` into its own struct, `ChatComposer`,
that does **not** implement `BottomPaneView`.
* Updates `BottomPane` so it has `composer: ChatComposer` and
`active_view: Option<Box<dyn BottomPaneView<'a> + 'a>>`. The idea is
that `active_view` takes priority and is displayed when it is `Some`;
otherwise, `ChatComposer` is displayed.
* While methods of `BottomPane` often have to check whether
`active_view` is present to decide which component to delegate to, the
code is more straightforward than before and introducing new
implementations of `BottomPaneView` should be less painful.
Because we want to retain the `TextArea` owned by `ChatComposer` even
when another view is displayed, to keep the ownership logic simple, it
seemed best to keep `ChatComposer` distinct from `BottomPaneView`.
This PR fixes things so that:
* when the `BottomPane` is in the `StatusIndicator` state, the border
should be dim
* when the `BottomPane` does not have input focus, the border should be
dim
To make it easier to enforce this invariant, this PR introduces
`BottomPane::set_state()` that will:
* update `self.state`
* call `update_border_for_input_focus()`
* request a repaint
This should make it easier to enforce other updates for state changes
going forward.
Some effects of this change:
- New formatting changes across many files. No functionality changes
should occur from that.
- Calls to `set_env` are considered unsafe, since this only happens in
tests we wrap them in `unsafe` blocks
As stated in `codex-rs/README.md`:
Today, Codex CLI is written in TypeScript and requires Node.js 22+ to
run it. For a number of users, this runtime requirement inhibits
adoption: they would be better served by a standalone executable. As
maintainers, we want Codex to run efficiently in a wide range of
environments with minimal overhead. We also want to take advantage of
operating system-specific APIs to provide better sandboxing, where
possible.
To that end, we are moving forward with a Rust implementation of Codex
CLI contained in this folder, which has the following benefits:
- The CLI compiles to small, standalone, platform-specific binaries.
- Can make direct, native calls to
[seccomp](https://man7.org/linux/man-pages/man2/seccomp.2.html) and
[landlock](https://man7.org/linux/man-pages/man7/landlock.7.html) in
order to support sandboxing on Linux.
- No runtime garbage collection, resulting in lower memory consumption
and better, more predictable performance.
Currently, the Rust implementation is materially behind the TypeScript
implementation in functionality, so continue to use the TypeScript
implmentation for the time being. We will publish native executables via
GitHub Releases as soon as we feel the Rust version is usable.
