all-repos
Clone all your repositories and apply sweeping changes.
Installation
pip install all-repos

CLI
All command line interfaces provided by all-repos provide the following
options:

-h / --help: show usage information
-C CONFIG_FILENAME / --config-filename CONFIG_FILENAME: use a non-default
config file (the default all-repos.json can be changed with the environment
variable ALL_REPOS_CONFIG_FILENAME).
--color {auto,always,never}: use color in output (default auto).

all-repos-complete [options]
Add git clone tab completion for all-repos repositories.
Requires jq to function.
Add to .bash_profile:
eval "$(all-repos-complete -C ~/.../all-repos.json --bash)"

all-repos-clone [options]
Clone all the repositories into the output_dir. If run again, this command
will update existing repositories.
Options:

-j JOBS / --jobs JOBS: how many concurrent jobs will be used to complete
the operation. Specify 0 or -1 to match the number of cpus. (default 8).

Sample invocations:

all-repos-clone: clone the repositories specified in all-repos.json
all-repos-clone -C all-repos2.json: clone using a non-default config
filename.

all-repos-find-files [options] PATTERN
Similar to a distributed git ls-files | grep -P PATTERN.
Arguments:

PATTERN: the python regex
to match.

Options:

--repos-with-matches: only print repositories with matches.

Sample invocations:

all-repos-find-files --repos setup.py: find all repositories containing
a setup.py.

all-repos-grep [options] [GIT_GREP_OPTIONS]

Writing your own source
First create a module. This module must have the following api:
A Settings class
This class will receive keyword arguments for all values in the
source_settings dictionary.
An easy way to implement the Settings class is by using a namedtuple:
Settings = collections.namedtuple('Settings', ('required_thing', 'optional'))
Settings.__new__.__defaults__ = ('optional default value',)

In this example, the required_thing setting is a required setting
whereas optional may be omitted (and will get a default value of
'optional default value').
def list_repos(settings: Settings) -> Dict[str, str]: callable
This callable will be passed an instance of your Settings class. It must
return a mapping from {repo_name: repository_url}. The repo_name is the
directory name inside the output_dir.
Push modules
all_repos.push.merge_to_master
Merges the branch directly to the default branch and pushes. The commands it
runs look roughly like this:
git checkout main
git pull
git merge --no-ff $BRANCH
git push origin HEAD

Optional push_settings

fast_forward (default: false): if true, perform a fast-forward
merge (--ff-only). If false, create a merge commit (--no-ff).

all_repos.push.github_pull_request
Pushes the branch to origin and then creates a github pull request for the
branch.
Required push_settings

api_key: the api key which the user will log in as.

Use the settings tab to create a
personal access token.
The minimum scope required to function is public_repo, though you'll
need repo to access private repositories.

api_key_env: alternatively API key can also be passed via an environment variable
username: the github username you will log in as.

Optional push_settings

fork (default: false): (if applicable) a fork will be created and pushed
to instead of the upstream repository. The pull request will then be made
to the upstream repository.
base_url (default: https://api.github.com) is the base URL to the Github
API to use (for Github Enterprise support set this to https://{your_domain}/api/v3).

all_repos.push.bitbucket_server_pull_request
Pushes the branch to origin and then creates a Bitbucket pull request for the branch.
Required push_settings

base_url: the Bitbucket server URL (eg bitbucket.domain.com)
username: the Bitbucket username you will log in as.
app_password: the authentication method for the above user to login with

Create an application password within your account settings.
We need the scope: Repositories -> Read

all_repos.push.gitlab_pull_request
Pushes the branch to origin and then creates a GitLab pull request for the branch.
Required push_settings

base_url: the GitLab server URL (eg https://{gitlab.domain.com}/api/v4)
api_key: the api key which the user will log in as.

Use the settings tab (eg https://{gitlab.domain.com}/-/profile/personal_access_tokens) to create a
personal access token.
We need the scope: write_repository.

api_key_env: alternatively API key can also be passed via an environment variable

all_repos.push.readonly
Does nothing.
push_settings
There are no configurable settings for readonly.
Writing your own push module
First create a module. This module must have the following api:
A Settings class
This class will receive keyword arguments for all values in the push_settings
dictionary.
def push(settings: Settings, branch_name: str) -> None:
This callable will be passed an instance of your Settings class. It should
deploy the branch. The function will be called with the root of the
repository as the cwd.
Writing an autofixer
An autofixer applies a change over all repositories.
all-repos provides several api functions to write your autofixers with:
all_repos.autofix_lib.add_fixer_args
def add_fixer_args(parser):

Adds the autofixer cli options.
Options:

--dry-run: show what would happen but do not push.
-i / --interactive: interactively approve / deny fixes.
-j JOBS / --jobs JOBS: how many concurrent jobs will be used to complete
the operation. Specify 0 or -1 to match the number of cpus. (default 1).
--limit LIMIT: maximum number of repos to process (default: unlimited).
--author AUTHOR: override commit author. This is passed directly to
git commit. An example: --author='Herp Derp <herp.derp@umich.edu>'.
--repos [REPOS [REPOS ...]]: run against specific repositories instead.
This is especially useful with xargs autofixer ... --repos. This can be
used to specify repositories which are not managed by all-repos.

all_repos.autofix_lib.from_cli
def from_cli(args, *, find_repos, msg, branch_name):

Parse cli arguments and produce autofix_lib primitives. Returns
(repos, config, commit, autofix_settings). This is handled separately from
fix to allow for fixers to adjust arguments.

find_repos: callback taking Config as a positional argument.
msg: commit message.
branch_name: identifier used to construct the branch name.

all_repos.autofix_lib.fix
def fix(
repos, *,
apply_fix,
check_fix=_noop_check_fix,
config: Config,
commit: Commit,
autofix_settings: AutofixSettings,
):

Apply the fix.

apply_fix: callback which will be called once per repository. The cwd
when the function is called will be the root of the repository.

all_repos.autofix_lib.run
def run(*cmd, **kwargs):

Wrapper around subprocess.run which prints the command it will run. Unlike
subprocess.run, this defaults check=True unless explicitly disabled.
Example autofixer
The trivial autofixer is as follows:
import argparse

from all_repos import autofix_lib

def find_repos(config):
return []

def apply_fix():
pass

def main(argv=None):
parser = argparse.ArgumentParser()
autofix_lib.add_fixer_args(parser)
args = parser.parse_args(argv)

repos, config, commit, autofix_settings = autofix_lib.from_cli(
args, find_repos=find_repos, msg='msg', branch_name='branch-name',
)
autofix_lib.fix(
repos, apply_fix=apply_fix, config=config, commit=commit,
autofix_settings=autofix_settings,
)

if __name__ == '__main__':
raise SystemExit(main())

You can find some more involved examples in all_repos/autofix:

all_repos.autofix.azure_pipelines_autoupdate: upgrade pinned azure
pipelines template repository references.
all_repos.autofix.pre_commit_autoupdate: runs pre-commit autoupdate.
all_repos.autofix.pre_commit_autopep8_migrate: migrates autopep8-wrapper
from pre-commit/pre-commit-hooks to mirrors-autopep8.
all_repos.autofix.pre_commit_cache_dir: updates the cache directory
for travis-ci / appveyor for pre-commit 1.x.
all_repos.autofix.pre_commit_flake8_migrate: migrates flake8 from
pre-commit/pre-commit-hooks to pycqa/flake8.
all_repos.autofix.pre_commit_migrate_config: runs
pre-commit migrate-config.
all_repos.autofix.setup_py_upgrade: runs setup-py-upgrade and then
setup-cfg-fmt to migrate setup.py to setup.cfg.
