Open source implementation of the [sourcetree](https://www.sourcetreeapp.com/) graph algorithm.

Given a list of commits and their parents, return a structure that tells you exactly how to draw the git graph.

It takes a json:

```json

[

  {"id": "1", "parents": ["3"], "non_related_attr": "non_related_value"},

  {"id": "2", "parents": ["3"]},

  {"id": "3", "parents": []}

]

```

and returns a structure that represent a git graph:

```json

[

  {"id": "1", "parents": ["3"], "non_related_attr": "non_related_value",

   "g": [0,0,"#5aa1be",[["#5aa1be",[[0,0,0],[0,2,0]]]]]},

  {"id": "2", "parents": ["3"],

   "g": [1,1,"#c065b8",[["#c065b8",[[1,1,0],[1,2,1],[0,2,0]]]]]},

  {"id": "3", "parents": [],

   "g": [2,0,"#5aa1be",[]]}

]

```

This structure can be directly rendered with D3.js, [you can try it out here.](http://alaingilbert.github.io/git2graph/)

## How to use

### Inline

`git2graph -j '[{"id": 1, "parents": ["2"]}, ...]'`

### File

`git2graph -f path/to/file.json`

### Repository

`git2graph -r` (You must be in the repository directory)

### In code

```go

package main

import (

  "fmt"

  "git2graph"

)

func main() {

  in := []map[string]any{

    {"id": "1", "parents": []string{"3"}},

    {"id": "2", "parents": []string{"3"}},

    {"id": "3", "parents": []string{}},

  }

  // Use this to render a whole graph in a single SVG

  out, err := git2graph.Get(in)

  fmt.Println(out, err)

  // Use this if you want to render each rows individually (for html table)

  out, err = git2graph.GetRows(in)

  fmt.Println(out, err)

}

```
