`git-get` is a better way to clone, organize and manage multiple git repositories.

## Description

`git-get` gives you two new git commands:
- **`git get`** clones repositories into an automatically created directory tree based on repo's URL (like golang's [`go get`](https://golang.org/cmd/go/)). It's dotfiles friendly, meaning you can also give it a file with a list of repositories and it will clone all of them.
- **`git list`** shows status of all your git repositories and their branches.

![Example](./docs/example.svg)

## Installation

Use Homebrew:
```
brew install grdl/tap/git-get
```

Or grab the [latest release](https://github.com/grdl/git-get/releases) and put the binaries on your PATH.

Each release contains two binaries: `git-get` and `git-list`. When put on PATH, git automatically recognizes them as custom commands and allows to run them as `git get` or `git list`.


## Usage

### git get
```
git get <REPO> [flags]

Flags:
  -b, --branch string       Branch (or tag) to checkout after cloning. Tag name needs to be prefixed with 'refs/tags/'. (default "master")
  -d, --dump string         Path to a dump file listing repos to clone. Ignored when <REPO> argument is used.
  -h, --help                Print this help and exit.
  -t, --host string         Host to use when <REPO> doesn't have a specified host. (default "github.com")
  -p, --privateKey string   Path to SSH private key. (default "~/.ssh/id_rsa")
  -r, --root string         Path to repos root where repositories are cloned. (default "~/repositories")
  -v, --version             Print version and exit.
```

The `<REPO>` argument can be any valid URL supported by git. Such as:
```
https://github.com/grdl/git-get
git@github.com:grdl/git-get.git
ssh://user@server/repository.git
file:///project/repository.git
```

#### Short URLs

`<REPO>` can be a short path without any protocol or host. In that case `git-get` will automatically use the `https` protocol and the configured host (github.com by default).
For example `git get grdl/git-get` will clone `https://github.com/grdl/git-get.git`.

#### Dump file

`git get` is dotfiles friendly. Using `--dump` flag, it accepts a file with a list of repositories and clones all of them.

Dump file format is simply:
- Each repo URL on a separate line.
- Each URL can have a suffix with a branch or tag name to check out after cloning. Without that suffix, `master` is used.
- Tag name should be prefixed with `refs/tags/`.

Example dump file content:
```
https://github.com/grdl/git-get refs/tags/v1.0.0
git@github.com:grdl/another-repository.git
```

You can generate a dump file with all your currently cloned repos by running:
```
git list --out dump > repos.dump
``` 


### git list
```
Usage:
  git list [flags]

Flags:
  -f, --fetch               First fetch from remotes before listing repositories.
  -h, --help                Print this help and exit.
  -o, --out string          Output format. Allowed values: [dump, flat, smart, tree]. (default "tree")
  -p, --privateKey string   Path to SSH private key. (default "~/.ssh/id_rsa")
  -r, --root string         Path to repos root where repositories are cloned. (default "~/repositories")
  -v, --version             Print version and exit.
```

`git list` provides different ways to view the list of the repositories and their statuses.

- **tree** (default) - repos rendered as a directory tree.
```
❯ git list
/home/grdl/repositories
└── github.com
    └── grdl
        ├── git-get master 1 ahead [ untracked ]
        │   └── development ok
        ├── homebrew-tap master ok
        └── testsite master ok
```

- **flat** - each repo (and each branch) on a new line with full path to the repo.
```
❯ git list -o flat
/home/grdl/repositories/github.com/grdl/git-get master 1 ahead [ untracked ]
                                                development ok
/home/grdl/repositories/github.com/grdl/homebrew-tap master ok
/home/grdl/repositories/github.com/grdl/testsite master ok
```

- **dump** - each repo URL with current branch on a new line. Accepted by `git get --dump` command.
```
❯ git list -o dump
https://github.com/grdl/git-get.git master
https://github.com/grdl/homebrew-tap master
https://github.com/grdl/testsite master
```

- **smart** (experimental) - similar to the tree view but saves space by automatically folding paths with only a single child. In theory it's supposed to be more readable but fails to prove it in practice so far :wink:
```
❯ git list -o smart
/home/grdl/repositories
github.com/grdl/
    git-get master 1 ahead [ untracked ]
            development ok
    homebrew-tap master ok
    testsite master ok
```


## Configuration

Each configuration flag listed in the [Usage](#Usage) section can be also specified using environment variables or .gitconfig file.

The order of precedence for configuration is as follows:
- command line flag (have the highest precedence)
- environment variable
- .gitconfig entry
- default value

> :warning: **WARNING!** :warning:
>
> When changing repos root path using .gitconfig or env variables, use a full path. For example, use `/home/greg/my_repos` instead of `~/my_repos` or `$HOME/my_repos`. This is becase `git-get` can't expand shell variables.


### Env variables

Use the `GITGET_` prefix and the uppercase flag name to set the configuration using env variables. For example, to use a different repos root path run:
```
export GITGET_ROOT=/path/to/my/repos
```

### .gitconfig file

You can define a `[gitget]` section inside your `.gitconfig` file and set the configuration flags there. A common and recommended pattern is to set `root` and `host` variables there if you don't want to use the defaults. Here's an example of a working snippet from `.gitconfig` file:
```
[gitget]
    root = /path/to/my/repos
    host = git.example.com
```

`git-get` looks for the `.gitconfig` file in the following locations:
- `$XDG_CONFIG_HOME/git/config`
- `~/.gitconfig`
- `~/.config/git/config`
- `/etc/gitconfig`


## Contributing

Pull requests are welcome. The project is still very much work in progress. Here's some of the missing features planned to be fixed soon:
- improvements to the `git list` output (feedback appreciated)
- submodules status
- info about stashes
- better recognition of different repo states: conflict, merging, rebasing, cherry picking etc.
- plenty of bugfixes and tests
