Git2graph

Open source implementation of the sourcetree 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:

[
  {"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:

[
  {"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.

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

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)
}

Use D3.js to render the graph represented by the output of Git2Graph.
