changesets-linux-x64 0.4.0

Git-based changelog manager for JavaScript, Python, and Go projects.

Changelog

Simple changelog management for projects using semantic versioning and git.

Example

Add

Add a changelog entry describing a set of changes.

changelog add

This creates a timestamped file in the .changelog directory ready to be added to source control and applied at a later time. Depending on how changelog is configured, the add command also adds the timestamped file to the git staging area and then commit all staged files using the provided description as the commit message.

[!NOTE] As a best practice, commit the timestamp file with the set of files the changelog entry describes. For example, run git add <FILES...> prior to running changelog add.

Apply

The apply command gathers previously created change descriptions from the .changelog directory and prepends the descriptions to the CHANGELOG.md file. The command also bumps semantic version numbers in specified files.

changelog apply

The resulting CHANGELOG.md file.

## 0.2.0

### Minor Changes

Getting Started

Within a project directory, run changelog init.

1. Current Version

Specifies the current version of the project. This version is tracked by changelog and considered the source of truth for project version. The version is bumped accordingly when changelog applies updates. The bumped version is then used to update specified version files. More on version files below.

2. Commit changelog entries

If yes, changelog add creates a changelog entry, adds the file to the git staging area and then commits all staged files using the changelog description as the commit message. If using this option, be sure to run git add <FILES...> prior to running changelog add to associate the new changelog entry with the files it describes.

If no, then changelog add creates a changelog entry but does not commit the files or run any git commands.

3. Commit changelog apply

changelog apply updates CHANGELOG.md and associated version files. If yes, then changelog apply will commit the changed files using the commit description chore: apply changelog.

4. Tag commit (not presented if previous answer == No)

If yes, changelog apply tags the commit created. This option is ignored if the answer to the previous question is No.

5. Tag format (not presented if either of the previous two answers == No)

Specify the tag to apply. This string is evaluated using handlebars and has access to the new version. Defaults to v{{version}}. This option is ignored if either of the previous two answers is No.

6. Version files

Specify JSON files containing fields that should match the project version. The JSON path can point to a nested field using dot notation. After changelog apply bumps the current package version it updates all the specified JSON files and fields.

[!WARNING] Currently, only JSON files are supported.

Config

changelog init creates a .changelog directory and the following two files.

config.json

Describes the config the init command walks through.

{
  "version": "1.0.0",
  "bumpFiles": [
    {
      "file": "package.json",
      "path": "version"
    },
    {
      "file": "some-json-file.json",
      "path": "path.to.nested"
    }
  ],
  "onAdd": {
    "commitFiles": true
  },
  "onApply": {
    "commitFiles": true,
    "tagCommit": true,
    "tagFormat": "v{{version}}"
  }
}

changelogTemplate.hbs

A handlebars file describing the template to use when adding entries to CHANGELOG.md. Users have full control of how the changelog entries are formatted. The following handlebars variables are available.

• version: The new project version after changelog apply finishes.
• oldVersion: The previous project version prior to changelog apply.
• patchChanges|minorChanges|majorChanges: A list of changes grouped by the level of change (patch, minor, or major). The variable is available if there is a change of that type present in the current update, otherwise its null.
  • sha: The full git commit hash for the change.
  • shortSha: The short git commit hash for the change.
  • description: Changelog description.
