A command line tool to visualize Git history graphs in a comprehensible way, following different branching models.

The image below shows an example using the [GitFlow](https://nvie.com/posts/a-successful-git-branching-model/) branching model for a comparison between graphs generated by git-graph (far left) versus other tools and Git clients.

> GitFlow was chosen for its complexity, while any other branching model is supported, including user-defined ones.

Decide for yourself which graph is the most comprehensible. :sunglasses:

If you want an **interactive Git terminal application**, see [**git-igitt**](https://github.com/mlange-42/git-igitt), which is based on git-graph.

## Features

* View structured graphs directly in the terminal
* Pre-defined and custom branching models and coloring
* Different styles, including ASCII-only (i.e. no "special characters")
* Custom commit formatting, like with `git log --format="..."`

## Installation

**Pre-compiled binaries**

1. Download the [latest binaries](https://github.com/mlange-42/git-graph/releases) for your platform
2. Unzip somewhere
3. *Optional:* add directory `git-graph` to your `PATH` environmental variable

**Using `cargo`**

In case you have [Rust](https://www.rust-lang.org/) installed, you can install with `cargo`:

```
cargo install git-graph
```

## Usage

**For detailed information, see the [manual](docs/manual.md)**.

For basic usage, run the following command inside a Git repository's folder:

```
git-graph
```

> Note: git-graph needs to be on the PATH, or you need use the full path to git-graph:
>
> ```
> C:/path/to/git-graph/git-graph
> ```

**Branching models**

Run git-graph with a specific model, e.g. `simple`:

```
git-graph --model simple
```

Alternatively, set the model for the current repository permanently:

```
git-graph model simple
```

**Get help**

For the full CLI help describing all options, use:

```
git-graph -h
git-graph --help
```

For **styles** and commit **formatting**, see the [manual](docs/manual.md).

## Custom branching models

Branching models are configured using the files in `APP_DATA/git-graph/models`.

* Windows: `C:\Users\\AppData\Roaming\git-graph`
* Linux: `~/.config/git-graph`
* OSX: `~/Library/Application Support/git-graph`

File names of any `.toml` files in the `models` directory can be used in parameter `--model`, or via sub-command `model`. E.g., to use a branching model defined in `my-model.toml`, use:

```
git-graph --model my-model
```

**For details on how to create your own branching models see the manual, section [Custom branching models](docs/manual.md#custom-branching-models).**

## Limitations

* Summaries of merge commits (i.e. 1st line of message) should not be modified! git-graph needs them to categorize merged branches.
* Supports only the primary remote repository `origin`.
* Does currently not support "octopus merges" (i.e. no more than 2 parents)
* On Windows PowerShell, piping to file output does not work properly (changes encoding), so you may want to use the default Windows console instead
