__gitup__ (the _git-repo-updater_)

gitup is a tool designed to update a large number of git repositories at once.
It is smart enough to handle multiple remotes, branches, dirty working
directories, and more, hopefully providing a great way to get everything
up-to-date for short periods of internet access between long periods of none.

gitup should work on OS X, Linux, and Windows. You should have the latest
version of git and either Python 2.7 or Python 3 installed.

# Installation

With [Homebrew](http://brew.sh/):

    brew install gitup

## From source

First:

    git clone git://github.com/earwig/git-repo-updater.git
    cd git-repo-updater

Then, to install for everyone:

    sudo python setup.py install

...or for just yourself (make sure you have `~/.local/bin` in your PATH):

    python setup.py install --user

Finally, simply delete the `git-repo-updater` directory, and you're done!

__Note:__ If you are using Windows, you may wish to add a macro so you can
invoke gitup in any directory. Note that `C:\python27\` refers to the
directory where Python is installed:

    DOSKEY gitup=c:\python27\python.exe c:\python27\Scripts\gitup $*

# Usage

There are two ways to update repos: you can pass them as command arguments,
or save them as "bookmarks".

For example:

    gitup ~/repos/foo ~/repos/bar ~/repos/baz

will automatically pull to the `foo`, `bar`, and `baz` git repositories.
Additionally, you can just type:

    gitup ~/repos

to automatically update all git repositories in that directory.

To add a bookmark (or bookmarks), either of these will work:

    gitup --add ~/repos/foo ~/repos/bar ~/repos/baz
    gitup --add ~/repos

Then, to update all of your bookmarks, just run gitup without args:

    gitup

Delete a bookmark:

    gitup --delete ~/repos

View your current bookmarks:

    gitup --list

You can mix and match bookmarks and command arguments:

    gitup --add ~/repos/foo ~/repos/bar
    gitup ~/repos/baz            # update 'baz' only
    gitup                        # update 'foo' and 'bar' only
    gitup ~/repos/baz --update   # update all three!

Update all git repositories in your current directory:

    gitup .

By default, gitup will fetch all remotes in a repository. Pass `--current-only`
(or `-c`) to make it fetch _only_ the remote tracked by the current branch.

Also by default, gitup will try to fast-forward all branches that have
upstreams configured. It will always skip branches where this is not possible
(e.g. dirty working directory or a merge/rebase is required). Pass
`--fetch-only` (or `-f`) to only fetch remotes.

After fetching, gitup will _keep_ remote-tracking branches that no longer exist
upstream. Pass `--prune` (or `-p`) to delete them, or set `fetch.prune` or
`remote.<name>.prune` in git config to do this by default.

For a full list of all command arguments and abbreviations:

    gitup --help

Finally, all paths can be either absolute (e.g. `/path/to/repo`) or relative
(e.g. `../my/repo`).
