RepoManager

Command line interface (CLI) for batch management of multiple Git repositories.

Overview

RepoManager is a wrapper for Git, the distributed version control system. RepoManager's wrapper functions allow a single git command to be executed across multiple git repositories.

For example, you have two git repositories named 'repo1' and 'repo2' and you want to check the status of both working folders.

without repo_manager

cd ~/workspace/delphi/repo1
git status

cd ~/workspace/delphi/repo2
git status

with repo_manager

repo status

suitable for

  • Maintenance and documentation of loosely connected source code repositories.
  • Synchronization/ light weight mirroring of data across a network. That is a job for rsync. Or is it? If you develop for multiple platforms across multiple (virtual) machines rsync'ing may not be the best option. If you already have everything tucked into git repositories, you can use a single 'repo pull' command to mirror all of your repositories to one location for backup or reference.

not suitable for

  • Maintaining related source code repositories. There are suitable tools for that including git's own 'git submodules', git-subtree, and GitSlave

Getting started with RepoManager

installation

dependencies

git > 1.7
ruby 1.87+

installation via gem

gem install repo_manager

installation via source

git clone git://github.com/robertwahler/repo_manager.git
cd repo_manager
bundle
bundle exec rake install

help

repo --help
repo --tasks
repo help generate:init

generate configuration folder structure

cd ~/workspace
repo generate:init .repo_manager

generate:init output

  init  creating initial config file at '/home/robert/workspace/.repo_manager/repo.conf'
create  .repo_manager/repo.conf
  init  creating initial file structure in '/home/robert/workspace/.repo_manager'
 exist  .repo_manager
create  .repo_manager/.gitignore
create  .repo_manager/assets/.gitignore
create  .repo_manager/global/default/asset.conf
create  .repo_manager/tasks/.gitignore

generate individual repository configurations files

generate multiple config files by searching a folder, one level deep, for git repositories

repo generate:config . --filter=mutagem,basic_*,repo_manager

generate config output

  collecting  collecting top level folder names
 configuring  setting discovered asset configuration paths
   comparing  looking for existing asset names
   comparing  looking for existing asset paths
Discovered assets
       found  basic_gem                                path => './basic_gem'
       found  basic_website                            path => './basic_website'
       found  basic_assets                             path => './basic_assets'
       found  repo_manager                             path => './repo_manager'
       found  basic_app                                path => './basic_app'
       found  mutagem                                  path => './mutagem'
       found  basic_rails                              path => './basic_rails'

Found 7 assets, write the configuration files (y/n)?

answer 'y'

creating  repo_manager configuration file for basic_gem
creating  repo_manager configuration file for basic_website
creating  repo_manager configuration file for basic_assets
creating  repo_manager configuration file for repo_manager
creating  repo_manager configuration file for basic_app
creating  repo_manager configuration file for mutagem
creating  repo_manager configuration file for basic_rails

Bash completion

Handy functions for use under Bash. These work fine on Win32 using Git-Bash.

  • rcd: repo cd (change directory). Wrapper for 'cd', allows for simple cd to the working folder on the filesystem referenced by the 'path' configuration variable.
  • rpushd: repo pushd (push directory). Wrapper for 'pushd'.

vim ~/.bashrc

function rcd(){ cd "$(repo --match=ONE --no-color path $@)"; }
function rpushd(){ pushd "$(repo path --match=ONE --no-color $@)"; }
alias rpopd="popd"

# provide completion for repo names
function _repo_names()
{
  local cur opts prev
  COMPREPLY=()
  cur="${COMP_WORDS[COMP_CWORD]}"
  opts=`repo list --list=name --no-color`

  COMPREPLY=( $(compgen -W "${opts}" -- ${cur}) )
  return 0
}
complete -F _repo_names rcd rpushd repo

Rake tasks

bundle exec rake -T

rake build             # Build repo_manager-0.7.1.gem into the pkg directory
rake cucumber          # Run Cucumber features
rake doc:clean         # Remove generated documenation
rake doc:generate      # Generate YARD Documentation
rake doc:undocumented  # List undocumented objects
rake gemfiles          # Generate .gemfiles via 'git ls-files'
rake install           # Build and install repo_manager-0.7.1.gem into system gems
rake release           # Create tag v0.7.1 and build and push repo_manager-0.7.1.gem to Rubygems
rake spec              # Run RSpec
rake test              # Run specs, both RSpec and Cucumber
