bump

bump bumps versions.

It accepts a version from standard input and prints the bumped version to standard output.

bump is:

• A small, unix-like utility, designed for use in build scripts.
• Compatible with semantic versioning, but does not require it.
• Agnostic to version prefixes, like "v".

Cookbook

Change default segment to bump

By default, bump will bump the rightmost segment. The idiomatic way to override this behavior is with an alias.

alias bump='bump -s 1' # bump the minor segment by default

Bump git tag

git tag "$(git describe --abbrev=0 --tags | bump)"
git push origin --tags

Bump tag based on latest commit keyword

If +major, +minor, +patch, or +pre are in the most recent commit, bump the version according to the keyword, otherwise bump the patch segment.

SEGMENT=$(git show -s --format=%s | awk -F'+' 'BEGIN{RS=" "} /\+/ {print $2}')
git tag "$(git describe --abbrev=0 --tags | bump -s "${SEGMENT:-patch}")"
