COMMANDS:
    version

The version is calculated based on the commit messages since last released.

Rules are the following:

• A breaking change commit will bump the major version

  * chore: release 1.2.10
  * feat!: first feature # => 2.0.0
  

• feat commits will bump the minor version

  * chore: release 1.2.10
  * feat: first feature
  * feat: second feature # => 1.3.0
  

• fix commits will bump the patch version

  * chore: release 1.2.10
  * fix: first fix
  * fix: second fix # => 1.2.11
  

You can mix different types of commits, the highest version will be used (breaking change > feat > fix).

* chore: release 1.2.10
* feat: first feature
* fix: first fix # => 1.3.0

Passing --pre-release [PREFIX] will generate a pre-release version.

Rules are the following:

• If the previous version is stable, then we compute the standard version bump and start a new pre-release version.

  * chore: release 1.2.10
  * feat: first feature
  * fix: first fix # => 1.3.0-beta.1
  

• If the previous version is a pre-release, with the same suffix, then we increment the pre-release version.

  * chore: release 1.3.0-beta.10
  * feat: first feature
  * fix: first fix # => 1.3.0-beta.11
  

• If the previous version is a pre-release, with a different suffix, then we use the same base version and start a new pre-release version.

  * chore: release 1.3.0-alpha.10
  * feat: first feature
  * fix: first fix # => 1.3.0-beta.1
  

💡 Tips

EasyBuild.Changelog use the last version in the changelog file to compute the next version.

For this reason, while working on a pre-release, it is advised to work in a separate branch from the main branch. This allows you to work on the pre-release while still being able to release new versions on the main branch.

* chore: release 1.2.10
| \
|  * feat!: remove `foo` API
|  * feat: add `bar` API        # => 2.0.0.beta.1
|  * fix: fix `baz` API
* fix: fix `qux` API
* chore: release 1.2.11
|  * fix: fix `qux` API         # => 2.0.0.beta.2
| /
* chore: release 2.0.0          # => 2.0.0

If you want to move out of pre-release, you simply need to remove the --pre-release CLI options.

Then the next version will be released using the base version of the previous pre-release.

* chore: release 1.3.0-beta.10
* feat: first feature
* fix: first fix # => 1.3.0

If you are not sure what will be calculated, you can use the --dry-run option to see the result without writing it to the changelog file.

If the computed version is not what you want, you can use the --force-version option to override the version to any value you want.

dotnet changelog-gen --force-version 2.0.0

EasyBuild.ChangelogGen supports monorepo. To do so, it use the Tag footer as specified in EasyBuild.CommitParser.

For example, if we have the following 3 commits:

----------------------------------------------
feat: add interface support

Tag: converter
----------------------------------------------
feat: add `export` support

Tag: converter
----------------------------------------------
feat: add new CLI options

Tag: cli
----------------------------------------------

Then I can run dotnet changelog-gen src/converter/CHANGELOG.md --tag converter to generate the changelog using only the commits with the converter tag.

dotnet changelog-gen src/converter/CHANGELOG.md --tag converter

• 0: Success
• 1: Error
• 100: Help was requested (allow other tools to detect if help was requested). This is left to the user to decide if they want to treat this as an error or not.
