git-sync-filtered 0.1.0

Sync filtered commits from private to public repository

git-sync-filtered

A thin wrapper around git-filter-repo for syncing filtered commits from a private repository to a public repository.

Overview

git-sync-filtered clones a private repository, filters it to only include specified paths using git-filter-repo, and pushes the result to a public repository's sync branch. This enables maintaining a public subset of a private repository while preserving commit history.

Installation

uv (recommended)

uv tool install git+https://github.com/Merge-42/git-sync-filtered

uvx (run without installing)

uvx git+https://github.com/Merge-42/git-sync-filtered \
  --private [e-mail]:org/private.git \
  --public [e-mail]:org/public.git \
  --keep src \
  --keep docs

pip

pip install git+https://github.com/Merge-42/git-sync-filtered

Usage

git-sync-filtered \
  --private [e-mail]:org/private.git \
  --public [e-mail]:org/public.git \
  --keep src \
  --keep docs

Using a paths file

Create a file with paths to keep (one per line, lines starting with # are comments):

src
docs
README.md

git-sync-filtered \
  --private [e-mail]:org/private.git \
  --public [e-mail]:org/public.git \
  --keep-from-file paths.txt

Options

Option	Description	Default
--private	Private repo path or URL	Required
--public	Public repo path or URL	Required
--keep	Paths to keep (specify multiple)	Required
--keep-from-file	File containing paths to keep	-
--sync-branch	Sync branch name	upstream/sync
--main-branch	Main branch name	main
--private-branch	Private branch to sync from	main
--dry-run	Show what would happen without making changes	false
--merge	Merge into main branch after sync	false
--force	Force push	false

How It Works

1. Clones the private repository
2. Runs git-filter-repo to filter to only the specified paths
3. Pushes filtered commits to the public repository's sync branch
4. Optionally merges the sync branch into main

The sync branch can then be merged into main manually or with --merge.
