pully

pully is a tool for managing a large number of Git repository checkouts effectively.

Why pully

pully was created to make managing and automating changes to multiple projects easier. There are two general use cases pully is designed to address. First, a mass action where a a set of projects is cloned and the same action is run on each project. Second, managing a local workspace for a set of projects.

Large scale changes

pully helps solve problems where you need to make the same action across multiple projects.

• Update the copyright date in the license file of all projects.
• Update pre-commit versions in all projects.
• Add badgie to all projects.

The recommended workflow in this case is to use pully to clone workspaces for mass actions not regular development. Avoid using the same project workspaces for both regular development and automated actions. Different branches, new files, and unknown state that are common in work in progress are likely to interfere with scripted changes.

Manage local workspaces

pully can be used to manage project checkouts for regular development. This makes onboarding new developers or setting up new environments easier. Common tasks like pulling the latest changes or pruning remote branches are easy to do. Beware of scripting changes to multiple projects since the status of each project may different and cause unexpected results.

With great power comes great responsibility

We recommend tremendous caution when automating repository changes. Some tips:

• Avoid making and committing changes in a single command.
• Ensure that a human is reviewing all changes before committing.
• Automate the creation of branches and merge requests as a minimally privileged user.

We expect some of these workflows to become pully features in the future.

Installation

python3 -m pip install pully

Quickstart

# add projects for pully to track
pully add -G saferatday0/library

# clone/fetch all projects
pully get

# run commands in checked out projects
pully run touch .gitkeep

Usage

Initialize a project workspace

Run pully init to create a project workspace.

pully init

A .pully.json will be created in the current directory that will be used to track project checkouts.

Add projects for tracking

Track any project by path:

pully add -P saferatday0/badgie

$ pully add -P saferatday0/badgie
searching for group id by full path saferatday0
searching for project id by full path
found project ids: [70752539]
found pully file at /home/user/projects/.pully.json
adding saferatday0/badgie

Track any group by path (subgroups are supported):

pully add -G saferatday0/library

$ pully add -G saferatday0/library
searching for group id by full path saferatday0/library
found group ids: [108399662]
creating new pullyfile at /home/user/projects
adding saferatday0/library/ansible
adding saferatday0/library/asciidoctor
...
adding saferatday0/library/verible
adding saferatday0/library/zola

Only newly added projects will be printed.

Clone/fetch all repositories

Call pully get to clone tracked projects to your local filesystem:

pully get

$ pully get
found pully file at /home/user/projects/.pully.json
cloning saferatday0/library/ansible (70326944)
cloning saferatday0/library/asciidoctor (70588591)
...
cloning saferatday0/library/zola (70432884)
cloning saferatday0/badgie (70752539)

The download strategy can be selected with -s/--strategy. Multiple strategies are available:

• clone (default) - Clone the repository, skipping if it is already present.

• fetch - Clone the repository if not found, or fetch updates if found.

• pull - Clone the repository if not found, or fetch and merge updates if found.

List all checked out projects

pully ls

$ pully ls
found pully file at /home/user/projects/.pully.json
cloned  70326944  saferatday0/library/ansible
cloned  70588591  saferatday0/library/asciidoctor
-       70588591  saferatday0/library/container
...

Filter by project path

The ls, pull, and run commands support filtering by local path prefix using the -p/--path-prefix option:

$ pully get -p saferatday0/badgie
found pully file at /home/bweir/Projects/gitlab.com/.pully.json
fetching saferatday0/badgie (70752539)
fetching saferatday0/badgie.me (45125259)

Running commands on repositories

The pully run command can be used to run a command in each repository.

Commands can be run in one of two ways:

• As arguments

• Using -c/--command

As arguments

When run this way, commands are run directly, a shell is not instantiated, and executable paths are fully resolved:

pully run git status

Command line options can be passed using --:

pully run -- ls -l

Using -c/--command

When run this way, a shell is launched, so shell features like indirection and pipes can be used

pully run -c 'echo "$(pwd) $(git branch)"'

["/bin/sh", "-euc"] is the default entrypoint. A different entrypoint can be specified with -e/--entrypoint:

pully run -e '["python3", "-c"]' -c 'fp = open(".gitignore", "a"); fp.write("*.pdf\n");'

$ pully run -e '["python3", "-c"]' -c 'fp = open(".gitignore", "a"); fp.write("*.pdf\n");'

Project environment variables

pully run populates a few environment variables with information about the current context.

PULLY_PROJECT_PATH

The path to the cloned project repository relative to the pully file directory.

$ echo $PULLY_PROJECT_PATH
saferatday0/handbook

PULLY_PROJECT_FULL_PATH

The full path to the cloned project repository.

$ echo $PULLY_PROJECT_FULL_PATH
/home/user/Projects/saferatday0/handbook

Cleanup

Reverting changes is easy:

pully run git checkout .

$ pully run git checkout .
found pully file at /home/bweir/blah/.pully.json
running saferatday0/library/ansible --------------------------------------------
Updated 1 path from the index
running saferatday0/library/asciidoctor ----------------------------------------
Updated 1 path from the index

Private repositories

pully can clone private repositories by setting the GITLAB_PRIVATE_TOKEN environment variable:

export GITLAB_PRIVATE_TOKEN="XXXXXX"
pully add -G private/namespace
pully get
