CLI

It is recommended to add the above action into your Fastfile, however sometimes you might want to run one-offs. To do so, you can run the following command from your terminal

fastlane run changelog_from_git_commits

To pass parameters, make use of the : symbol, for example

fastlane run changelog_from_git_commits parameter1:"value1" parameter2:"value2"

It's important to note that the CLI supports primitive types like integers, floats, booleans, and strings. Arrays can be passed as a comma delimited string (e.g. param:"1,2,3"). Hashes are not currently supported.

It is recommended to add all fastlane actions you use to your Fastfile.

Source code

This action, just like the rest of fastlane, is fully open source, view the source code on GitHub
