Agent IDE — Codex fork for AI-native development environment
c92dbea7c1
Background Streaming assistant prose in tui2 was being rendered with viewport-width wrapping during streaming, then stored in history cells as already split `Line`s. Those width-derived breaks became indistinguishable from hard newlines, so the transcript could not "un-split" on resize. This also degraded copy/paste, since soft wraps looked like hard breaks. What changed - Introduce width-agnostic `MarkdownLogicalLine` output in `tui2/src/markdown_render.rs`, preserving markdown wrap semantics: initial/subsequent indents, per-line style, and a preformatted flag. - Update the streaming collector (`tui2/src/markdown_stream.rs`) to emit logical lines (newline-gated) and remove any captured viewport width. - Update streaming orchestration (`tui2/src/streaming/*`) to queue and emit logical lines, producing `AgentMessageCell::new_logical(...)`. - Make `AgentMessageCell` store logical lines and wrap at render time in `HistoryCell::transcript_lines_with_joiners(width)`, emitting joiners so copy/paste can join soft-wrap continuations correctly. Overlay deferral When an overlay is active, defer *cells* (not rendered `Vec<Line>`) and render them at overlay close time. This avoids baking width-derived wraps based on a stale width. Tests + docs - Add resize/reflow regression tests + snapshots for streamed agent output. - Expand module/API docs for the new logical-line streaming pipeline and clarify joiner semantics. - Align scrollback-related docs/comments with current tui2 behavior (main draw loop does not flush queued "history lines" to the terminal). More details See `codex-rs/tui2/docs/streaming_wrapping_design.md` for the full problem statement and solution approach, and `codex-rs/tui2/docs/tui_viewport_and_history.md` for viewport vs printed output behavior. |

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.
Using Codex with your ChatGPT plan
