## Problem When unified-exec background sessions appear while the status indicator is visible, the bottom pane can grow by one row to show a dedicated footer line. That row insertion/removal makes the composer jump vertically and produces visible jitter/flicker during streaming turns. ## Mental model The bottom pane should expose one canonical background-exec summary string, but it should surface that string in only one place at a time: - if the status indicator row is visible, show the summary inline on that row; - if the status indicator row is hidden, show the summary as the standalone unified-exec footer row. This keeps status information visible while preserving a stable pane height. ## Non-goals This change does not alter unified-exec lifecycle, process tracking, or `/ps` behavior. It does not redesign status text copy, spinner timing, or interrupt handling semantics. ## Tradeoffs Inlining the summary preserves layout stability and keeps interrupt affordances in a fixed location, but it reduces horizontal space for long status/detail text in narrow terminals. We accept that truncation risk in exchange for removing vertical jitter and keeping the composer anchored. ## Architecture `UnifiedExecFooter` remains the source of truth for background-process summary copy via `summary_text()`. `BottomPane` mirrors that text into `StatusIndicatorWidget::update_inline_message()` whenever process state changes or a status widget is created. Rendering enforces single-surface output: the standalone footer row is skipped while status is present, and the status row appends the summary after the elapsed/interrupt segment. ## Documentation pass Added non-functional docs/comments that make the new invariant explicit: - status row owns inline summary when present; - unified-exec footer row renders only when status row is absent; - summary ordering keeps elapsed/interrupt affordance in a stable position. ## Observability No new telemetry or logs are introduced. The behavior is traceable through: - `BottomPane::set_unified_exec_processes()` for state updates, - `BottomPane::sync_status_inline_message()` for status-row synchronization, - `StatusIndicatorWidget::render()` for final inline ordering. ## Tests - Added `bottom_pane::tests::unified_exec_summary_does_not_increase_height_when_status_visible` to lock the no-height-growth invariant. - Updated the unified-exec status restoration snapshot to match inline rendering order. - Validated with: - `just fmt` - `cargo test -p codex-tui --lib` --------- Co-authored-by: Sayan Sisodiya <sayan@openai.com>
npm i -g @openai/codex
or brew install --cask codex
Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Install globally with your preferred package manager:
# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex
Then simply run codex to get started.
You can also go to the latest GitHub Release and download the appropriate binary for your platform.
Each GitHub Release contains many executables, but in practice, you likely want one of these:
- macOS
- Apple Silicon/arm64:
codex-aarch64-apple-darwin.tar.gz - x86_64 (older Mac hardware):
codex-x86_64-apple-darwin.tar.gz
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
