Docker

Remote repository:

docker run --rm samber/git-contrib-graph \
       --git-remote https://github.com/samber/invoice-as-a-service \
       --interval week --full-graph

Local repository:

docker run --rm \
       -v /students/john-doe/project-a-b-c:/repo \
       samber/git-contrib-graph \
       --git-path /repo --interval week  --full-graph

Todo

• json output
• image output
• custom branch
• clone on filesystem instead of memory
• test with lot of public github repo and compare contrib graphs
• better example in readme
• get graph for only one contributor

Contributing

⚠ Quick and dirty project ;)

About git api and go-git library

Git log command do much more things than you think !

• At low level, initial git commit does not have diff (because it has no parent). Then we fetch number of changes (add/del) based on number of lines.
• Merge commits have 2 parents. In that case, changes (add/del) are displayed once in git log command, but are provided twice in git api (in both original and merge commit)
