Generate a CalVer version string from a log of Git commits.
Assuming you are not rewriting history in your release branches, calver can
just be used in CI without having to use your git tags for persistence.
calver will make a version string triple that is not incompatible with the
SemVer syntax: there are no leading zeroes.
Given a git log, the version string MAJOR.MINOR.PATCH will be printed, where
MAJOR is the year of the last commitMINOR is the month and day of the last commitPATCH is the number of commits on the last dayTo stay somewhat readable and still be ordered properly and agree with SemVer
syntax, the MINOR version is calculated by adding the day with 100 * the
month: January 1 is 101, January 11 is 111, November 1 is 1101, etc.
If this is your git log:
❯ git log --pretty=format:"%h %ad - %s" --date=short | head
