💪 git-machete is a robust tool that **simplifies your git workflows**.<br/>

🦅 The _bird's eye view_ provided by git-machete makes **merges/rebases/push/pulls hassle-free**
even when **multiple branches** are present in the repository
(master/develop, your topic branches, teammate's branches checked out for review, etc.).<br/>

🎯 Using this tool, you can maintain **small, focused, easy-to-review pull requests** with little effort.

👁 A look at a `git machete status` gives an instant answer to the questions:
* What branches are in this repository?
* What is going to be merged (rebased/pushed/pulled) and to what?

🚜 `git machete traverse` semi-automatically traverses the branches, helping you effortlessly rebase, merge, push and pull.

## Install

We provide a couple of alternative ways of installation.

**Instructions for installing bash, zsh, and fish completion scripts are provided in [completion/README.md](completion/README.md).**

git-machete requires Python >= 3.6. Python 2.x is no longer supported.

### Using Homebrew (macOS & most Linux distributions)

```shell script
brew install git-machete
```

### Using snap (most Linux distributions)

**Tip:** check the [guide on installing snapd](https://snapcraft.io/docs/installing-snapd) if you don't have Snap support set up yet in your system.

```shell script
sudo snap install --classic git-machete
```

It can also be installed via Ubuntu Software (simply search for `git-machete`).

**Note:** classic confinement is necessary to ensure access to the editor installed in the system (to edit e.g. .git/machete file or rebase TODO list).

### Using apt-get via PPA (Ubuntu)

**Tip:** run `sudo apt-get install -y software-properties-common` first if `add-apt-repository` is not available on your system.

```shell script
sudo add-apt-repository ppa:virtuslab/git-machete
sudo apt-get update
sudo apt-get install -y python3-git-machete
```

### Using rpm (Fedora/RHEL/CentOS/openSUSE...)

Download the rpm package from the [latest release](https://github.com/VirtusLab/git-machete/releases/latest)
and install either by opening it in your desktop environment or with `rpm -i git-machete-*.noarch.rpm`.

### Using Alpine, Arch, Gentoo & other Linux distro-specific package managers

Check [Repology](https://repology.org/project/git-machete/versions) for the available distro-specific packages.

### Using Nix (macOS & most Linux distributions)

On macOS and most Linux distributions, you can install via [Nix](https://nixos.org/nix):

```shell script
nix-channel --add https://nixos.org/channels/nixos-unstable unstable  # if you haven't set up any channels yet
nix-env -i git-machete
```

**Note:** since `nixos-21.05`, `git-machete` is included in the stable channels as well.
The latest released version, however, is generally available in the unstable channel.
Stable channels may lag behind; see [repology](https://repology.org/project/git-machete/versions) for the current channel-package mapping.

### Using pip with sudo (system-wide install)

You need to have Python and `pip` installed from system packages.

```shell script
sudo -H pip install git-machete
```

**Tip:** pass an extra `-U` flag to `pip install` to upgrade an already installed version.

### Using pip without sudo (user-wide install)

You need to have Python and `pip` installed from system packages.

```shell script
pip install --user git-machete
```

Please verify that your `PATH` variable has `${HOME}/.local/bin/` included.

**Tip:** pass an extra `-U` flag to `pip install` to upgrade an already installed version.

### Using conda

```shell script
conda install -c conda-forge git-machete
```

<br/>

## Quick start

### Discover the branch layout

```shell script
cd your-repo/
git machete discover
```

See and possibly edit the suggested layout of branches.
Branch layout is always kept as a `.git/machete` text file, which can be edited directly or via `git machete edit`.

### See the current repository state
```shell script
git machete status --list-commits
```

**Green** edge means the given branch is **in sync** with its parent. <br/>
**Red** edge means it is **out of sync** &mdash; parent has some commits that the given branch does not have. <br/>
**Gray** edge means that the branch is **merged** to its parent.

### Rebase, reset to remote, push, pull all branches as needed
```shell script
git machete traverse --fetch --start-from=first-root
```

Put each branch one by one in sync with its parent and remote tracking branch.

### Fast-forward merge a child branch into the current branch
```shell script
git machete advance
```

Useful for merging the child branch to the current branch in a linear fashion (without creating a merge commit).

### GitHub integration

Check out the given PRs into local branches, also traverse chain of pull requests upwards, adding branches one by one to git-machete and check them out locally as well: <br/>
```shell script
git machete github checkout-prs [--all | --by=<github-login> | --mine | <PR-number-1> ... <PR-number-N>]
```

Create the PR, using the upstream (parent) branch from `.git/machete` as the base: <br/>
```shell script
git machete github create-pr [--draft]
```

**Note**: for private repositories, a GitHub API token with `repo` access is required.
This will be resolved from the first of:
1. `GITHUB_TOKEN` env var.
2. Contents of the `.github-token` file in the home directory (`~`). This file has to be manually created by the user.
3. Auth token from the current [`gh`](https://cli.github.com/) configuration.
4. Auth token from the current [`hub`](https://github.com/github/hub) configuration.

<br/>


## FAQ

#### I've run `git machete discover`... but the branch layout I see in `.git/machete` doesn't exactly match what I expected. Am I doing something wrong?

[//]: # (For how to find Medium header anchors, see https://www.freecodecamp.org/news/how-to-link-to-a-specific-paragraph-in-your-medium-article-2018-table-of-contents-method-e66595fea549/)
No! It's all right, `discover` is based on an (imperfect)
[heuristic](https://medium.com/virtuslab/git-machete-strikes-again-traverse-the-git-rebase-jungle-even-faster-with-v2-0-f43ebaf8abb0#0544)
which usually yields branch layout close to what the user would expect.
It still might not be perfect and &mdash; for example &mdash; declare branches to be children of `main`/`develop` instead of each other.

Just run [`git machete edit`](https://git-machete.readthedocs.io/en/stable/#edit) to fix the layout manually.
If you're working on JetBrains IDEs, you can use [git-machete IntelliJ plugin](https://github.com/VirtusLab/git-machete-intellij-plugin#git-machete-intellij-plugin)
to have branch name completion when editing `.git/machete` file.

Also, consider [`git machete github checkout-prs`](#github-integration) instead of `git machete discover` if you already have GitHub PRs opened.

<br/>

#### Can I use `git merge` for dealing with stacked PRs?

There are two commonly used ways to put a branch back in sync with its base (parent) branch:
1. rebase the branch onto its base branch
2. merge the base branch into the branch

While git-machete supports merging base branch (like `main`) to update the branch
([`git machete traverse --merge`](https://git-machete.readthedocs.io/en/stable/#traverse)),
this approach **works poorly with stacked PRs**.
You might end up with a very tangled history very quickly, and a non-trivial sequence of `git cherry-pick`s might be needed to restore order.

That is why we recommend using rebase over merge for stacked PRs.
However, we still recommend using merge for the narrow case of [backporting hotfixes](https://slides.com/plipski/git-machete/#/11).

<br/>

#### Sometimes when I run `update` or `traverse`, too many commits are taken into the rebase... how to fix that?

Contrary to the popular misconception, git doesn't have a notion of
["commits belonging to a branch"](https://git-scm.com/book/en/v2/Git-Branching-Branches-in-a-Nutshell).
A branch is just a movable reference to a commit.

This makes it hard in general case to determine the range of commits that form the "unique history" of the given branch.
There's an entire algorithm in git-machete for determining the
[_fork point_](https://medium.com/virtuslab/make-your-way-through-the-git-rebase-jungle-with-git-machete-e2ed4dbacd02#1ac9)
of the branch (i.e. the place after which the unique history of the branch starts).

One thing that you can do to help fork-point algorithm in its job,
is to **not delete** local branches instantly after they're merged or discarded.
They (or specifically, their [reflogs](https://virtuslab.github.io/tips/#git/git-reflog)) will be still useful for a while
to determine fork points for other branches (and thus, the range of commits taken into rebase).

Also, you can always override fork point for a branch explicitly
with [`git machete fork-point --override-to...`](https://git-machete.readthedocs.io/#fork-point) command.

💪 git-machete is a robust tool that **simplifies your git workflows**.<br/>

🦅 The _bird's eye view_ provided by git-machete makes **merges/rebases/push/pulls hassle-free**
even when **multiple branches** are present in the repository
(master/develop, your topic branches, teammate's branches checked out for review, etc.).<br/>

🎯 Using this tool, you can maintain **small, focused, easy-to-review pull requests** with little effort.

👁 A look at a `git machete status` gives an instant answer to the questions:
* What branches are in this repository?
* What is going to be merged (rebased/pushed/pulled) and to what?

🚜 `git machete traverse` semi-automatically traverses the branches, helping you effortlessly rebase, merge, push and pull.

## Install

We provide a couple of alternative ways of installation.

**Instructions for installing bash, zsh, and fish completion scripts are provided in [completion/README.md](completion/README.md).**

git-machete requires Python >= 3.6. Python 2.x is no longer supported.

### Using Homebrew (macOS & most Linux distributions)

```shell script
brew install git-machete
```

### Using snap (most Linux distributions)

**Tip:** check the [guide on installing snapd](https://snapcraft.io/docs/installing-snapd) if you don't have Snap support set up yet in your system.

```shell script
sudo snap install --classic git-machete
```

It can also be installed via Ubuntu Software (simply search for `git-machete`).

**Note:** classic confinement is necessary to ensure access to the editor installed in the system (to edit e.g. .git/machete file or rebase TODO list).

### Using apt-get via PPA (Ubuntu)

**Tip:** run `sudo apt-get install -y software-properties-common` first if `add-apt-repository` is not available on your system.

```shell script
sudo add-apt-repository ppa:virtuslab/git-machete
sudo apt-get update
sudo apt-get install -y python3-git-machete
```

### Using rpm (Fedora/RHEL/CentOS/openSUSE...)

Download the rpm package from the [latest release](https://github.com/VirtusLab/git-machete/releases/latest)
and install either by opening it in your desktop environment or with `rpm -i git-machete-*.noarch.rpm`.

### Using Alpine, Arch, Gentoo & other Linux distro-specific package managers

Check [Repology](https://repology.org/project/git-machete/versions) for the available distro-specific packages.

### Using Nix (macOS & most Linux distributions)

On macOS and most Linux distributions, you can install via [Nix](https://nixos.org/nix):

```shell script
nix-channel --add https://nixos.org/channels/nixos-unstable unstable  # if you haven't set up any channels yet
nix-env -i git-machete
```

**Note:** since `nixos-21.05`, `git-machete` is included in the stable channels as well.
The latest released version, however, is generally available in the unstable channel.
Stable channels may lag behind; see [repology](https://repology.org/project/git-machete/versions) for the current channel-package mapping.

### Using pip with sudo (system-wide install)

You need to have Python and `pip` installed from system packages.

```shell script
sudo -H pip install git-machete
```

**Tip:** pass an extra `-U` flag to `pip install` to upgrade an already installed version.

### Using pip without sudo (user-wide install)

You need to have Python and `pip` installed from system packages.

```shell script
pip install --user git-machete
```

Please verify that your `PATH` variable has `${HOME}/.local/bin/` included.

**Tip:** pass an extra `-U` flag to `pip install` to upgrade an already installed version.

### Using conda

```shell script
conda install -c conda-forge git-machete
```

<br/>

## Quick start

### Discover the branch layout

```shell script
cd your-repo/
git machete discover
```

See and possibly edit the suggested layout of branches.
Branch layout is always kept as a `.git/machete` text file, which can be edited directly or via `git machete edit`.

### See the current repository state
```shell script
git machete status --list-commits
```

**Green** edge means the given branch is **in sync** with its parent. <br/>
**Red** edge means it is **out of sync** &mdash; parent has some commits that the given branch does not have. <br/>
**Gray** edge means that the branch is **merged** to its parent.

### Rebase, reset to remote, push, pull all branches as needed
```shell script
git machete traverse --fetch --start-from=first-root
```

Put each branch one by one in sync with its parent and remote tracking branch.

### Fast-forward merge a child branch into the current branch
```shell script
git machete advance
```

Useful for merging the child branch to the current branch in a linear fashion (without creating a merge commit).

### GitHub integration

Check out the given PRs into local branches, also traverse chain of pull requests upwards, adding branches one by one to git-machete and check them out locally as well: <br/>
```shell script
git machete github checkout-prs [--all | --by=<github-login> | --mine | <PR-number-1> ... <PR-number-N>]
```

Create the PR, using the upstream (parent) branch from `.git/machete` as the base: <br/>
```shell script
git machete github create-pr [--draft]
```

**Note**: for private repositories, a GitHub API token with `repo` access is required.
This will be resolved from the first of:
1. `GITHUB_TOKEN` env var.
2. Contents of the `.github-token` file in the home directory (`~`). This file has to be manually created by the user.
3. Auth token from the current [`gh`](https://cli.github.com/) configuration.
4. Auth token from the current [`hub`](https://github.com/github/hub) configuration.

## FAQ

#### I've run `git machete discover`... but the branch layout I see in `.git/machete` doesn't exactly match what I expected. Am I doing something wrong?

[//]: # (For how to find Medium header anchors, see https://www.freecodecamp.org/news/how-to-link-to-a-specific-paragraph-in-your-medium-article-2018-table-of-contents-method-e66595fea549/)
No! It's all right, `discover` is based on an (imperfect)
[heuristic](https://medium.com/virtuslab/git-machete-strikes-again-traverse-the-git-rebase-jungle-even-faster-with-v2-0-f43ebaf8abb0#0544)
which usually yields branch layout close to what the user would expect.
It still might not be perfect and &mdash; for example &mdash; declare branches to be children of `main`/`develop` instead of each other.

Just run [`git machete edit`](https://git-machete.readthedocs.io/en/stable/#edit) to fix the layout manually.
If you're working on JetBrains IDEs, you can use [git-machete IntelliJ plugin](https://github.com/VirtusLab/git-machete-intellij-plugin#git-machete-intellij-plugin)
to have branch name completion when editing `.git/machete` file.

Also, consider [`git machete github checkout-prs`](#github-integration) instead of `git machete discover` if you already have GitHub PRs opened.

<br/>

#### Can I use `git merge` for dealing with stacked PRs?

There are two commonly used ways to put a branch back in sync with its base (parent) branch:
1. rebase the branch onto its base branch
2. merge the base branch into the branch

While git-machete supports merging base branch (like `main`) to update the branch
([`git machete traverse --merge`](https://git-machete.readthedocs.io/en/stable/#traverse)),
this approach **works poorly with stacked PRs**.
You might end up with a very tangled history very quickly, and a non-trivial sequence of `git cherry-pick`s might be needed to restore order.

That is why we recommend using rebase over merge for stacked PRs.
However, we still recommend using merge for the narrow case of [backporting hotfixes](https://slides.com/plipski/git-machete/#/11).

<br/>

#### Sometimes when I run `update` or `traverse`, too many commits are taken into the rebase... how to fix that?

Contrary to the popular misconception, git doesn't have a notion of
["commits belonging to a branch"](https://git-scm.com/book/en/v2/Git-Branching-Branches-in-a-Nutshell).
A branch is just a movable reference to a commit.

This makes it hard in general case to determine the range of commits that form the "unique history" of the given branch.
There's an entire algorithm in git-machete for determining the
[_fork point_](https://medium.com/virtuslab/make-your-way-through-the-git-rebase-jungle-with-git-machete-e2ed4dbacd02#1ac9)
of the branch (i.e. the place after which the unique history of the branch starts).

One thing that you can do to help fork-point algorithm in its job,
is to **not delete** local branches instantly after they're merged or discarded.
They (or specifically, their [reflogs](https://virtuslab.github.io/tips/#git/git-reflog)) will be still useful for a while
to determine fork points for other branches (and thus, the range of commits taken into rebase).

Also, you can always override fork point for a branch explicitly
with [`git machete fork-point --override-to...`](https://git-machete.readthedocs.io/#fork-point) command.
