svu

Semantic Version Util is a tool to manage semantic versions at ease!

You can print the current version, increase patch/minor/major manually or just get the next tag based on your git log!

example usage

svu

Based on the log between the latest tag and HEAD, prints the next tag.

aliases: svu next and svu n

$ svu
v1.3.0

commit messages vs what they do

Commit message	Tag increase
fix: fixed something	Patch
feat: added new button to do X	Minor
fix: fixed thing xyz BREAKING CHANGE: this will break users because of blah	Major
fix!: fixed something	Major
feat!: added blah	Major
chore: foo	Nothing

svu current

Prints the current tag with no changes.

alias: svu c

Examples:

$ svu current
v1.2.3

$ svu current
v1.2.3-alpha.1+22

svu major

Increases the major of the latest tag and prints it. As per the Semver spec, it'll also clear the pre-release and build identifiers are cleaned up.

Examples:

$ svu current
v1.2.3-alpha.2+123

$ svu major
v2.0.0

$ svu major --pre-release alpha.3 --build 243
v2.0.0-alpha.3+243

svu minor

Increases the minor of the latest tag and prints it. As per the Semver spec, it'll also clear the pre-release and build identifiers are cleaned up.

alias: svu m

Examples:

$ svu current
v1.2.3-alpha.2+123

$ svu minor
v1.3.0

$ svu minor --pre-release alpha.3 --build 243
v1.3.0-alpha.3+243

svu patch

Increases the patch of the latest tag and prints it. As per the Semver spec, if the version has a pre-release or build identifier, they'll be cleaned up and no patch increment will be made. You can force an increment by using --force-patch-increment.

alias: svu p

Examples:

$ svu current
v1.2.3-alpha.2+123

$ svu patch
v1.2.3

$ svu patch --force-patch-increment
v1.2.4

$ svu patch --pre-release alpha.3 --build 243
v1.2.3-alpha.3+243

tag mode

By default svu will get the latest tag from the current branch. Using the --tag-mode flag this behaviour can be altered:

Flag	Description	Git command used under the hood
--tag-mode current-branch	Get latest tag from current branch.	git describe --tags --abbrev=0
--tag-mode all-branches	Get latest tag across all branches.	git describe --tags $(git rev-list --tags --max-count=1)

stripping the tag prefix

--strip-prefix removes any prefix from the version output. For example, v1.2.3 would be output as 1.2.3.

The default prefix is v, however a custom prefix can be supplied using --prefix. So for --prefix=foo/v --strip-prefix and tag foo/v1.2.3, the output would be 1.2.3.

adding a suffix

You can use --pre-release and --build to set the respective Semver identifiers to the resulting version.

force patch version increment

Setting the --force-patch-increment flag forces a patch version increment regardless of the commit message content.

creating tags

The idea is that svu will just print things, so it's safe to run at any time.

You can create tags by wrapping it in an alias. For example, I have one like this:

alias gtn='git tag $(svu next)'

So, whenever I want to create a tag, I just run gtn.

install

macOS

brew install caarlos0/tap/svu

linux

apt

echo 'deb [trusted=yes] https://apt.fury.io/caarlos0/ /' | sudo tee /etc/apt/sources.list.d/caarlos0.list
sudo apt update
sudo apt install svu

yum

echo '[caarlos0]
name=caarlos0
baseurl=https://yum.fury.io/caarlos0/
enabled=1
gpgcheck=0' | sudo tee /etc/yum.repos.d/caarlos0.repo
sudo yum install svu

docker

docker run --rm -v $PWD:/tmp --workdir /tmp ghcr.io/caarlos0/svu --help

Using go install

Make sure that $GOPATH/bin is in your $PATH, because that's where this gets installed:

go install github.com/caarlos0/svu@latest

manually

Or download one from the releases tab and install manually.
