gerrit-change-list

Recursively scan git repositories under a path and list commits merged within a time range — by committer date, not author date — across every repo it finds, with Gerrit patch links.

Built for the recurring question: "a problem showed up; who landed what into these repos in this window, and what are the patch links?"

Why committer date

In a Gerrit workflow the author date is when the developer wrote the patch; the committer date is when it actually landed on the branch (merged / cherry-picked / rebased in). When you git pull / repo sync to latest and ask "what got merged on July 5th", you want committer date. git log --since/--until filter on committer date, so that is what this tool uses.

Features

• Three time selectors (pick one): --day, --hour, or --since/--until.
• Cross-repo by default: recursively finds every .git under the path — standalone repos and repo-tool-managed multi-repos. Nested submodules are picked up too.
• Gerrit patch links: host derived from each repo's origin remote; link is https://<host>/q/<Change-Id> (clickable, no network/auth needed).
• Two outputs: a colored terminal table grouped by repo, plus a Markdown report file.
• Zero runtime dependencies — standard library only.

Install

Prerequisite: git must be on PATH (the tool shells out to git log / git config). Python ≥ 3.10.

From PyPI:

pip install gerrit-change-list
gerrit-change-list --version

Editable install (for development, with test/lint deps):

pip install -e ".[dev]"

Or run from source with no install:

./main.py --version

Usage

# Whole calendar day (local timezone)
gerrit-change-list /path/to/workspace --day 2026-07-05

# Whole calendar hour
gerrit-change-list /path/to/workspace --hour "2026-07-05 14"

# Precise range (--until defaults to now when omitted)
gerrit-change-list /path/to/workspace --since "2026-07-05 14:00" --until "2026-07-05 15:30"

# Force a timezone for the selectors
gerrit-change-list . --day 2026-07-05 --tz Asia/Shanghai

# Filter by submitter; show committer instead of author
gerrit-change-list . --since "2026-07-05" --author "alice" --by-committer

[!NOTE] The tool only reads local state — it does not pull. Run git pull / repo sync to latest first.

Example

Terminal output (colors shown when stdout is a TTY and NO_COLOR is unset):

$ gerrit-change-list /path/to/workspace --day 2026-07-05
gerrit-change-list  range: 2026-07-05 .. 2026-07-06
3 commit(s) across 2 repo(s)

A Markdown report with the same content is written next to the run (gerrit-change-list-report-<timestamp>.md by default).

Output

• Terminal: a color table grouped by repo, columns Merge time | Patch | Submitter | Subject. Color is gated on TTY and NO_COLOR.
• Markdown report: written to gerrit-change-list-report-<timestamp>.md (override with -o, suppress with --no-markdown).

[!TIP] To preview the rendered Markdown report: grip <file.md> (local server) or pandoc <file.md> -s -o <file.html> (standalone HTML).

Options

How it works

• Repo discovery: a "repo" is any directory containing a .git entry — a .git directory (normal checkout) or a .git file (worktree / submodule). The scan never enters .git/ or .repo/ metadata, but keeps walking a found repo's subdirectories so nested submodules are found. Each repo-tool project is itself a normal git repo, so it is covered.
• Time field: git log --since/--until filter on the committer date. Author date is not used for filtering.
• Patch link: the Gerrit host is parsed from each repo's origin remote URL. For ssh:// remotes the port (e.g. Gerrit's 29418) is dropped — that's the push port; the web UI runs on HTTPS (443). The link https://<host>/q/<Change-Id> is Gerrit's search-redirect URL. Commits without a Change-Id fall back to the commit hash.

Development

pip install -e ".[dev]"
pytest                   # tests
black --check src tests  # format check (CI-enforced)
python -m build          # build wheel
