sver

Calculates semantic versions in a git repo.

sver requires the latest tag of the current branch to be a semantic version, otherwise it fails. Semantic versions with plus elements like 1.0.2+gold are not supported and also fail.

If the latest tag in the current branch points to HEAD, no pre-release version information is added.

Otherwise, <commit_timestamp>.<branch_commit_count>.g<commit_short_hash> is appended to the version string. <commit_timestamp> is in the format yyyymmddHHMMSS.

If there are uncommitted changes to the source tree, the -dirty string is appended to the final version string.

For example: 1.2.0-20201027184820.3186.g4fc2e9e5-dirty

Calculating the next version

sver can also calculate the next semantic version based on the current version. To do so, use the --next flag. Possible values are major, minor or patch.

Container image tags

When using the tags sub-command, sver will look at existing tags in an image repository, and figure out which tags you should apply to the image you're building from the current git commit.

For example if you have tags 1.0.0, 1.1.0 and 2.1.0 and your current tag is 2.1.0, running sver tags will output:

• 2.1.0 - your new version
• 2.1 - because it’s the latest in the 2.1.* series
• 2 - because it's the latest in the 2.* series
• latest - because there’s no other version that’s higher

If you then work on top of tag 1.0.0, and create a patch tagged 1.0.1, running sver tags will output:

• 1.0.1 - your new version
• 1.0 - because it's the latest in the 1.0.* series

It’s not outputting latest because 2.1.0 is higher than 1.0.1, and it’s not outputting 1 because 1.1.0 is higher than 1.0.1.
