Core developer activity
This page shows the GitHub activity of the members of the LAMMPS core developer team in lammps/lammps, by calendar month.
- commits is counting commits in the
developbranch and count for whoever wrote them, not for whoever merged them. - PRs merged is the opposite: it counts the pull requests a member merged, whoever wrote them.
- reviews counts every review submitted.
- approvals counts reviews that approved a pull request.
- comments counts conversation comments on issues and pull requests together with inline comments on a diff.
