git-notes-db 0.1.31

Store and access structured data in git-notes

git-notes-db

This tool helps store structured information in git-notes. It aims to be usable manually, but also for creating other scripts.

Usage

When setting value specify a name as the first argument (this will be refs/notes/<name>). In this example we use test_results. The second argument is the commit this data is about. The third argument is what to store, this can be anything that jq accepts, including standard JSON.

All operations must be run from within a git repository.

$ git-notes-db set test_results HEAD '{passed: false, older_results: []}'

To read the data back;

$ git-notes-db get test_results HEAD
> {"passed": false, "older_results": []}

When updating, the jq expression gets any original value as an input (or null if no original value is stored). This allows for selective updating, or merging data.

$ git-notes-db set test_results HEAD '{passed: true, older_results: .older_results + [.passed]}'
$ git-notes-db get test_results HEAD
> {"passed": true, "older_results": [false]}

Other commands

get_all

It's also possible to get all known results with get_all. This also accepts jq expressions which modify the output results.

match

Return's results matching supplied jq expression.

Todo

• Allow limiting queries/get by git revision range.
• Add subcommand to run some executable and store result. See git-branchless for inspiration. - Could make nice tui with textual.
• Package and push to pypi.
• Nix flake.
• Add helper to push given notes to a remote.
• Add helper to automatically configure git to fetch notes from remote.
• Add note merge helper. Use jq expression to handle merge.
• Add ability to specify a key (e.g. message). When this key is present on a result that's being set, also update a secondary human readable note for including in git log output with notes.displayRef.
• Add toggle for match that outputs just commits newline separated.
• Add option for match and get_all that stops searching after n results are outputted.
• Add option for match that fails if number of results is outside a given range.
• githooks / ci.
• More tutorial with usage examples.
• Feel like I've reinvented the wheel with the way I've built up the cli commands. I've not seen the state of CLI helper libraries recently. Maybe try Typer. or felix-martel/pydanclick: Add click options from a Pydantic model

Development Notes

• Haven't decided whether I want to primarily use github or gitlab.
• A bit over-engineered. Trying out some stuff.
• Trying out jujutsu VCS, commits might be weird until I work it out.
• Had originally planned to use more asyncio. Right now a bunch of stuff is async that probably doesn't need to be. Will leave this behind incase I end up wanting to parallelise things in future.
• Ruff should be used to format code.
• Basedpyright and ruff should both be run for static testing.
• Write unit/integration tests suitable for pytest.
