TUI: fix request_user_input wrapping for long option labels (#11123)
## Summary

This PR fixes long-text rendering in the `request_user_input` TUI
overlay while preserving a clear two-column option layout. (Issue
https://github.com/openai/codex/issues/11093)

Before:
- very long option labels could push description text into a narrow
right-edge strip
- option labels were effectively single-line when descriptions were
present, causing truncation/poor readability
- label and description wrapping interacted in one combined wrapped line

/>

After:
- option labels wrap inside the left column
- descriptions wrap independently inside the right column
- row measurement and row rendering use the same wrapping path, so
layout stays stable

## Problem

`request_user_input` needs to handle verbose prompts/options. With
oversized labels:
- descriptions could collapse into a thin, hard-to-read column
- important label context was lost

## Root Cause

In shared row rendering (`selection_popup_common`):
- rows were wrapped as a single combined line
- auto column sizing could still place `desc_col` too far right for long
labels
- `request_user_input` rows did not provide wrap metadata to align
continuation lines after the option prefix

## What Changed

### 1) `request_user_input` rows opt into wrapped labels
File: `codex-rs/tui/src/bottom_pane/request_user_input/mod.rs`

- In `option_rows()`, compute the rendered option prefix (`› 1. ` / ` 2.
`) and set `wrap_indent` from its display width.
- Apply the same behavior to the synthetic “None of the above” row.
- Add long-text snapshot test coverage
(`question_with_very_long_option_text` +
`request_user_input_long_option_text_snapshot`).

### 2) Shared renderer now has an opt-in two-column wrapping path
File: `codex-rs/tui/src/bottom_pane/selection_popup_common.rs`

- Add focused helpers:
  - `should_wrap_name_in_column`
  - `wrap_two_column_row`
  - `wrap_standard_row`
  - `wrap_row_lines`
  - `apply_row_state_style`
- For opted-in rows (plain option rows with `wrap_indent` +
description), wrap label and description independently in their own
columns.
- Keep the legacy standard wrapping path for non-opted rows.
- Use the same `wrap_row_lines` function in both rendering and height
measurement to keep them in sync.

### 3) Keep column sizing simple and derived from existing fixed split
constants
File: `codex-rs/tui/src/bottom_pane/selection_popup_common.rs`

- Keep fixed mode at `3/10` left column (`30/70` split).
- In auto modes, cap label width using those same fixed constants (max
70% label, min 30% description), instead of extra special-case
constants/branches.
- Add/keep narrow-width safety guard in `wrap_two_column_row` so
extremely small widths do not panic.

### 4) Snapshot coverage
File: `codex-rs/tui/src/bottom_pane/request_user_input/snapshots/

codex_tui__bottom_pane__request_user_input__tests__request_user_input_long_option_text.snap`

- Add snapshot for long-label/long-description two-column rendering
behavior.

Codex CLI (Rust Implementation)

We provide Codex CLI as a standalone, native executable to ensure a zero-dependency install.

Installing Codex

Today, the easiest way to install Codex is via npm:

npm i -g @openai/codex
codex

You can also install via Homebrew (brew install --cask codex) or download a platform-specific release directly from our GitHub Releases.

Documentation quickstart

What's new in the Rust CLI

The Rust implementation is now the maintained Codex CLI and serves as the default experience. It includes a number of features that the legacy TypeScript CLI never supported.

Config

Codex supports a rich set of configuration options. Note that the Rust CLI uses config.toml instead of config.json. See docs/config.md for details.

Model Context Protocol Support

MCP client

Codex CLI functions as an MCP client that allows the Codex CLI and IDE extension to connect to MCP servers on startup. See the configuration documentation for details.

MCP server (experimental)

Codex can be launched as an MCP server by running codex mcp-server. This allows other MCP clients to use Codex as a tool for another agent.

Use the @modelcontextprotocol/inspector to try it out:

npx @modelcontextprotocol/inspector codex mcp-server

Use codex mcp to add/list/get/remove MCP server launchers defined in config.toml, and codex mcp-server to run the MCP server directly.

Notifications

You can enable notifications by configuring a script that is run whenever the agent finishes a turn. The notify documentation includes a detailed example that explains how to get desktop notifications via terminal-notifier on macOS. When Codex detects that it is running under WSL 2 inside Windows Terminal (WT_SESSION is set), the TUI automatically falls back to native Windows toast notifications so approval prompts and completed turns surface even though Windows Terminal does not implement OSC 9.

codex exec to run Codex programmatically/non-interactively

To run Codex non-interactively, run codex exec PROMPT (you can also pass the prompt via stdin) and Codex will work on your task until it decides that it is done and exits. Output is printed to the terminal directly. You can set the RUST_LOG environment variable to see more about what's going on. Use codex exec --ephemeral ... to run without persisting session rollout files to disk.

Experimenting with the Codex Sandbox

To test to see what happens when a command is run under the sandbox provided by Codex, we provide the following subcommands in Codex CLI:

# macOS
codex sandbox macos [--full-auto] [--log-denials] [COMMAND]...

# Linux
codex sandbox linux [--full-auto] [COMMAND]...

# Windows
codex sandbox windows [--full-auto] [COMMAND]...

# Legacy aliases
codex debug seatbelt [--full-auto] [--log-denials] [COMMAND]...
codex debug landlock [--full-auto] [COMMAND]...

Selecting a sandbox policy via --sandbox

The Rust CLI exposes a dedicated --sandbox (-s) flag that lets you pick the sandbox policy without having to reach for the generic -c/--config option:

# Run Codex with the default, read-only sandbox
codex --sandbox read-only

# Allow the agent to write within the current workspace while still blocking network access
codex --sandbox workspace-write

# Danger! Disable sandboxing entirely (only do this if you are already running in a container or other isolated env)
codex --sandbox danger-full-access

The same setting can be persisted in ~/.codex/config.toml via the top-level sandbox_mode = "MODE" key, e.g. sandbox_mode = "workspace-write".

Code Organization

This folder is the root of a Cargo workspace. It contains quite a bit of experimental code, but here are the key crates:

  • core/ contains the business logic for Codex. Ultimately, we hope this to be a library crate that is generally useful for building other Rust/native applications that use Codex.
  • exec/ "headless" CLI for use in automation.
  • tui/ CLI that launches a fullscreen TUI built with Ratatui.
  • cli/ CLI multitool that provides the aforementioned CLIs via subcommands.
