How to use

go-semantic-release config file Create a file with the name .release.yml or anything else, but you need to set to every command -c <your config file>

github:
  repo: "go-semantic-release"
  user: "nightapes"
assets:
  - name: ./build/go-semantic-release
    compress: false
  - name: ./build/go-semantic-release.exe
    compress: false
hooks:
  preRelease:
    - name: echo $RELEASE_VERSION
  postRelease:
    - name: echo $RELEASE_VERSION
integrations:
  npm:
    enabled: true

CommitFormat

Branch

You can define which kind of release should be created for different branches.

Supported release kinds:

• release -> v1.0.0
• rc -> v1.0.0-rc.0
• beta -> v1.0.0-beta.0
• alpha -> v1.0.0-alpha.0

Add a branch config to your config

branch:
  <branch-name>: <kind>

Release

At the moment we support releases to gitlab and github.

Github

You need to set the env GITHUB_TOKEN with an access token.

release: 'github'
github:
  user: "<user/group"
  repo: "<repositroyname>"
  ## Optional, if you are not using github.com
  customUrl: <https://your.github>
  ## Optional, if you want to change the default tag prefix ("v")
  tagPrefix: ""

Gitlab

You need to set the env GITLAB_ACCESS_TOKEN with an personal access token.

release: 'gitlab'
gitlab:
  repo: "<repositroyname>"  ## Example group/project
  ## Optional, if your not using gitlab.com
  customUrl: <https://your.gitlab>
  ## Optional, if you want to change the default tag prefix ("v")
  tagPrefix: ""

You can find an example .gitlab-ci.yml in the examples folder.

Git only

Only via https at the moment. You need write access to your git repository

release: 'git'
git:
  email: "<email>" # Used for creating tag
  user: "<user>" : # Used for creating tag and pushing
  auth: "<token>" # Used for pushing, can be env "$GIT_TOKEN", will be replaced with env
  ## Optional, if you want to change the default tag prefix ("v")
  tagPrefix: ""

Assets

You can upload assets to a release

Support for gitlab and github. If you want, you can let the file be compressed before uploading

assets:
  - name: ./build/go-semantic-release
    compress: false

Hooks

Hooks will run when calling release. Hooks run only if a release will be triggered. You can define hooks which run before or after the release. The shell commands will run in order, you can access the current release version via an environment variable RELEASE_VERSION

hooks:
  preRelease:
  - name: echo $RELEASE_VERSION
  postRelease:
  - name: echo $RELEASE_VERSION

Integrations

Integrations are simple helpers to make integration with existing tools easier. At the moment npm is supported, the integration will set the version before release to the package.json

integrations:
  npm:
    enabled: true

Version

go-semantic-release has two modes for calculating the version: automatic or manual.

Automatic

Version will be calculated on the next or release command

Manual

If you don't want that go-semantic-release is calculating the version from the commits, you can set the version by hand with following command:

./go-semantic-release set 1.1.1

Print version

Print the next version, can be used to add version to your program

./go-semantic-release next // show next version (calculated by new commits since last version)
./go-semantic-release last // show last released version 

Example with go-lang

go build -ldflags "--X main.version=`./go-semantic-release next`"

Create release

./go-semantic-release release 

Write changelog to file

This will write all changes beginning from the last git tag til HEAD to a changelog file. Default changelog file name if nothing is given via --file: CHANGELOG.md. Note that per default the new changelog will be prepended to the existing file. With --max-file-size a maximum sizes of the changelog file in megabytes can be specified. If the size exceeds the limit, the current changelog file will be moved to a new file called <filename>-<1-n>.<file extension>. The new changelog will be written to the <filename>. The default maximum file size limit is 10 megabytes.

./go-semantic-release changelog --max-file-size 10

This will overwrite the given changelog file if its existing, if not it will be created.

./go-semantic-release changelog --overwrite
