## Summary - Promote `js_repl` to an experimental feature that users can enable from `/experimental`. - Add `js_repl` experimental metadata, including the Node prerequisite and activation guidance. - Add regression coverage for the feature metadata and the `/experimental` popup. ## What Changed - Changed `Feature::JsRepl` from `Stage::UnderDevelopment` to `Stage::Experimental`. - Added experimental metadata for `js_repl` in `core/src/features.rs`: - name: `JavaScript REPL` - description: calls out interactive website debugging, inline JavaScript execution, and the required Node version (`>= v24.13.1`) - announcement: tells users to enable it, then start a new chat or restart Codex - Added a core unit test that verifies: - `js_repl` is experimental - `js_repl` is disabled by default - the hardcoded Node version in the description matches `node-version.txt` - Added a TUI test that opens the `/experimental` popup and verifies the rendered `js_repl` entry includes the Node requirement text. ## Testing - `just fmt` - `cargo test -p codex-tui` - `cargo test -p codex-core` (unit-test phase passed; stopped during the long `tests/all.rs` integration suite)
codex-core
This crate implements the business logic for Codex. It is designed to be used by the various Codex UIs written in Rust.
Dependencies
Note that codex-core makes some assumptions about certain helper utilities being available in the environment. Currently, this support matrix is:
macOS
Expects /usr/bin/sandbox-exec to be present.
When using the workspace-write sandbox policy, the Seatbelt profile allows
writes under the configured writable roots while keeping .git (directory or
pointer file), the resolved gitdir: target, and .codex read-only.
Network access and filesystem read/write roots are controlled by
SandboxPolicy. Seatbelt consumes the resolved policy and enforces it.
Seatbelt also supports macOS permission-profile extensions layered on top of
SandboxPolicy:
- no extension profile provided:
keeps legacy default preferences read access (
user-preference-read). - extension profile provided with no
macos_preferencesgrant: does not add preferences access clauses. macos_preferences = "readonly": enables cfprefs read clauses anduser-preference-read.macos_preferences = "readwrite": includes readonly clauses plususer-preference-writeand cfprefs shm write clauses.macos_automation = true: enables broad Apple Events send permissions.macos_automation = ["com.apple.Notes", ...]: enables Apple Events send only to listed bundle IDs.macos_accessibility = true: enablescom.apple.axservermach lookup.macos_calendar = true: enablescom.apple.CalendarAgentmach lookup.
Linux
Expects the binary containing codex-core to run the equivalent of codex sandbox linux (legacy alias: codex debug landlock) when arg0 is codex-linux-sandbox. See the codex-arg0 crate for details.
All Platforms
Expects the binary containing codex-core to simulate the virtual apply_patch CLI when arg1 is --codex-run-as-apply-patch. See the codex-arg0 crate for details.
