A GitHub action for automatically evaluating the logic level impacts of Pull Requests.
With a simple setup in your GitHub Action:
- name: diffctx
uses: williamfzc/diffctx@v0.3.13
with:
lang: "golang"Diffctx will automatically analyse the diff (and the context of diff) every new PullRequests in your repo, and leave comments for indicating which part you should care most:
Based on LSIF, diffctx will not only analyse the lines contained by the diff, but also the full scope of your repo, and understand it well.
diffctx can be directly used with GitHub Action.
