## Summary This PR makes app-server-provided image URLs first-class attachments in TUI, so they survive resume/backtrack/history recall and are resubmitted correctly. <img width="715" height="491" alt="Screenshot 2026-02-12 at 8 27 08 PM" src="https://github.com/user-attachments/assets/226cbd35-8f0c-4e51-a13e-459ef5dd1927" /> Can delete the attached image upon backtracking: <img width="716" height="301" alt="Screenshot 2026-02-12 at 8 27 31 PM" src="https://github.com/user-attachments/assets/4558d230-f1bd-4eed-a093-8e1ab9c6db27" /> In both history and composer, remote images are rendered as normal `[Image #N]` placeholders, with numbering unified with local images. ## What changed - Plumb remote image URLs through TUI message state: - `UserHistoryCell` - `BacktrackSelection` - `ChatComposerHistory::HistoryEntry` - `ChatWidget::UserMessage` - Show remote images as placeholder rows inside the composer box (above textarea), and in history cells. - Support keyboard selection/deletion for remote image rows in composer (`Up`/`Down`, `Delete`/`Backspace`). - Preserve remote-image-only turns in local composer history (Up/Down recall), including restore after backtrack. - Ensure submit/queue/backtrack resubmit include remote images in model input (`UserInput::Image`), and keep request shape stable for remote-image-only turns. - Keep image numbering contiguous across remote + local images: - remote images occupy `[Image #1]..[Image #M]` - local images start at `[Image #M+1]` - deletion renumbers consistently. - In protocol conversion, increment shared image index for remote images too, so mixed remote/local image tags stay in a single sequence. - Simplify restore logic to trust in-memory attachment order (no placeholder-number parsing path). - Backtrack/replay rollback handling now queues trims through `AppEvent::ApplyThreadRollback` and syncs transcript overlay/deferred lines after trims, so overlay/transcript state stays consistent. - Trim trailing blank rendered lines from user history rendering to avoid oversized blank padding. ## Docs + tests - Updated: `docs/tui-chat-composer.md` (remote image flow, selection/deletion, numbering offsets) - Added/updated tests across `tui/src/chatwidget/tests.rs`, `tui/src/app.rs`, `tui/src/app_backtrack.rs`, `tui/src/history_cell.rs`, and `tui/src/bottom_pane/chat_composer.rs` - Added snapshot coverage for remote image composer states, including deleting the first of two remote images. ## Validation - `just fmt` - `cargo test -p codex-tui` ## Codex author `codex fork 019c2636-1571-74a1-8471-15a3b1c3f49d`
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.
