This PR adds support for chained (layered) config.toml file merging for clients that use the app server interface. This feature already exists for the TUI, but it does not work for GUI clients. It does the following: * Changes code paths for new thread, resume thread, and fork thread to use the effective config based on the cwd. * Updates the `config/read` API to accept an optional `cwd` parameter. If specified, the API returns the effective config based on that cwd path. Also optionally includes all layers including project config files. If cwd is not specified, the API falls back on its older behavior where it considers only the global (non-project) config files when computing the effective config. The changes in codex_message_processor.rs look deceptively large. They mostly just involve moving existing blocks of code to a later point in some functions so it can use the cwd to calculate the config. This PR builds upon #9509 and should be reviewed and merged after that PR. Tested: * Verified change with (dependent, as-yet-uncommitted) changes to IDE Extension and confirmed correct behavior The full fix requires additional changes in the IDE Extension code base, but they depend on this PR.
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.
