codex-cocalc

Small builder to produce codex binaries with a CoCalc-specific patch that enriches file_change events (adds pre_contents) for JSONL output from codex exec.

What it does

• Clones the upstream codex repo at a tag (default rust-v0.76.0).
• Applies a minimal patch to codex exec JSONL output so file_change events include the original file contents (per path) after a patch apply. This lets downstream tools show diffs/patchflow without re-reading files at event time.
• Builds codex-cli (and related binaries) and places them in dist/.

Usage (manual)

TAG=rust-v0.76.0 ./build.sh
ls dist/

GitHub Actions

A workflow (.github/workflows/build.yml) runs ./build.sh and uploads the built binaries as an artifact (codex-cocalc-binaries).

Patch files

• file_change_pre_contents.patch: extends FileChangeItem with optional pre_contents.
• event_processor_with_jsonl_output.patch: captures pre-contents at patch begin and emits them in the file_change item.

Notes

• Changes are minimal and upstream-friendly; if upstream changes break the patch, adjust the patch files and rerun.
• Binaries are suitable for per-project containers or local use (cocalc-plus).
