mergestat-lite

mergestat-lite is a command-line tool for running SQL queries on git repositories and related data sources. It's meant for ad-hoc querying of source-code on disk through a common interface (SQL), as an alternative to patching together various shell commands. It can execute queries that look like:

-- how many commits have been authored by [email protected]?
SELECT count(*) FROM commits WHERE author_email = '[email protected]'

It installs a binary named mergestat.

More in-depth examples and documentation can be found on our dedicated documentation site.

Installation

See the full instructions in our documentation.

Homebrew

brew tap mergestat/mergestat
brew install mergestat

Docker

docker run -v "${PWD}:/repo" mergestat/mergestat "select count(*) from commits"

Examples

SQL queries can be executed in the CLI on local or remote git repositories. Remote repos are cloned to a temporary directory at runtime.

The --format flag can be used to output json, ndjson, csv and more (see mergestat -h). This can be useful for piping/using with other tools.

Higher level commands such as mergestat summarize commits generate reports without requiring a SQL input. Learn more here about the available flags such as --start to change the date range and --json to output as JSON.
