Incr is a tool to help you easily increment the version number of your NPM or Mix packages.

The process is detailed as follow:

• Find the relevant file(s) (e.g.: package.json and package-lock.json or mix.exs).
• Determine the existing version number.
• Increment the specified segment. If you increment the minor segment, the patch segment is set to 0 and the same goes for the major segment, the minor and patch segments are set to 0.
• Write the newly incremented version number in the relevant file(s).
• Create a new git commit with the relevant file with the version number as the default message (e.g.: 0.2.1).
• Create a new git tag pointing to the new git commit with the version number prefixed by a 'v' as the name (e.g.: v0.2.1).
• 💥

~> gem install incr

To increment the patch segment of your NPM package version number:

~> incr npm patch

To increment the minor segment of your Mix package version number:

~> incr mix minor

Here are some arguments that can be used with incr:

• -d : Directory where to search for the version files (default: .)
• -t : Tag name pattern, where %s will be replaced with the new version (default: v%s)
• --[no-]commit : Commit changes. (default: enabled)
• --[no-]tag : Create a git tag. (default: enabled)

Example:

~> incr --no-tag -d ./subprojects/web/ -t MyCustomTagPrefix/%s npm patch

This will :

• Search for package.json and package-lock.json files inside ./subprojects/web/ and update the patch version
• Commit the changes under the message MyCustomTagPrefix/2.3.4
• Not create a tag with the new version
