- Add internal/node package: reads/writes package.json version (single or multi-path via node.package_json / node.package_jsons) - Add maven.pom_paths support: update multiple pom.xml files in one release commit; pom_paths overrides pom_path; --pom flag clears pom_paths - Add git.bump_rules config: per-type control of which version component bumps (breaking/feat/fix accept "patch" or "minor"); wired through version.Next() as a new sixth parameter - Extract injectable function vars (absPath, gitAllCommits, gitCommitsSince, gitCommitFiles) to enable error-path testing without interfaces - Achieve 100% per-package statement coverage across all 12 packages Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

# releaser
|
|
|
|
|
|
|
|
A CI-friendly release automation tool for GitFlow workflows using Conventional Commits.
|
|
|
|
## Problem
|
|
|
|
Standard tools like `semantic-release` are designed for trunk-based development. In a GitFlow setup with versioned release branches (`release/1.1`, `release/1.2`), they either fail to respect the branch's version range or require brittle configuration.
|
|
|
|
`releaser` is built for this exact workflow: it reads the branch name to pin the `major.minor`, parses Conventional Commits to determine the patch increment, and handles everything from `pom.xml` update to GitLab/GitHub tag+release creation.
|
|
|
|
## How it works
|
|
|
|
```
|
|
release/1.2 branch
|
|
└─ last tag: 1.2.3 (or none → start at 1.2.0)
|
|
└─ commits since tag → Conventional Commits analysis
|
|
└─ next version: 1.2.4
|
|
```
|
|
|
|
1. **Branch parsing** — extracts `major.minor` from branch name (e.g. `release/1.2` → `1.2`)
|
|
2. **Tag discovery** — finds the latest tag matching `major.minor.*` on the current branch
|
|
3. **Commit analysis** — parses Conventional Commits between last tag and HEAD
|
|
4. **Version bump** — increments patch (the minor is owned by the branch)
|
|
5. **Release** — updates `pom.xml`, commits, tags, creates GitLab or GitHub release
|
|
|
|
## Version bump rules
|
|
|
|
By default, all releasable commits bump the **patch** component (minor is pinned to the branch). You can override this per commit type via `git.bump_rules` in `.releaser.yml`:
|
|
|
|
| Commit type | Default | Configurable via `bump_rules` |
|
|
|------------------|---------|------------------------------------------------|
|
|
| `fix:` | patch | `fix: "minor"` to bump minor instead |
|
|
| `feat:` | patch | `feat: "minor"` to bump minor instead |
|
|
| `feat!:` / `BREAKING CHANGE` | patch | `breaking: "minor"` to bump minor |
|
|
| `chore:`, `docs:`, etc. | none | — |
|
|
| unparseable msg | none | non-strict mode: silently ignored |
|
|
|
|
## Usage
|
|
|
|
```bash
|
|
# Scaffold a default .releaser.yml in the current repository
|
|
releaser --init
|
|
|
|
# Simulate next version (no side effects)
|
|
releaser --dry-run
|
|
|
|
# Full release: update pom.xml + CHANGELOG.md, commit, tag, push, create release
|
|
releaser
|
|
|
|
# Commit and tag locally — skip push and release creation
|
|
releaser --no-push
|
|
|
|
# Push commit and tag but skip creating the release
|
|
releaser --no-release
|
|
|
|
# Update files but stop before committing (review first)
|
|
releaser --no-commit
|
|
# … then commit manually and re-run:
|
|
releaser --tag-only
|
|
|
|
# Explicitly target a branch (useful in detached HEAD CI)
|
|
releaser --branch release/1.2
|
|
|
|
# Write changelog to a custom file
|
|
releaser --changelog-file CHANGES.md
|
|
|
|
# Show configuration sources, commit list, and version decision
|
|
releaser --verbose --dry-run
|
|
|
|
# Target a specific pom.xml
|
|
releaser --pom path/to/pom.xml
|
|
|
|
# Override tag prefix from CLI (empty = no prefix)
|
|
releaser --tag-prefix ""
|
|
|
|
# Override branch pattern (e.g. also match hotfix/ branches)
|
|
releaser --branch-pattern "^(?:.*/)?(?:release|hotfix)/(\d+)\.(\d+)$"
|
|
|
|
# Write dotenv artifact to a custom path (or "" to disable)
|
|
releaser --release-env-file deploy/version.env
|
|
```
|
|
|
|
## Configuration
|
|
|
|
`releaser` reads `.releaser.yml` from the repository root. All fields are optional — missing values fall back to the defaults shown below.
|
|
|
|
```yaml
|
|
git:
|
|
tag_prefix: "" # default: no prefix; set to "v" for v-prefixed tags
|
|
branch_pattern: "^(?:.*/)?release/(\\d+)\\.(\\d+)$" # two capture groups: major, minor
|
|
commit_message: "chore(release): {version} [skip ci]"
|
|
author_name: "" # defaults to git config user.name
|
|
author_email: "" # defaults to git config user.email
|
|
releasable_types: # default: all three
|
|
- fix
|
|
- feat
|
|
- breaking
|
|
bump_rules: # which version component each type bumps
|
|
breaking: "patch" # "minor" to bump minor on breaking changes
|
|
feat: "patch"
|
|
fix: "patch"
|
|
|
|
maven:
|
|
pom_path: "pom.xml" # single pom.xml, relative to repo root
|
|
# pom_paths: # multi-module: list overrides pom_path
|
|
# - "pom.xml"
|
|
# - "module-a/pom.xml"
|
|
# - "module-b/pom.xml"
|
|
|
|
node: # opt-in — no default; omit to skip
|
|
# package_json: "package.json" # single path
|
|
# package_jsons: # monorepo: list overrides package_json
|
|
# - "packages/frontend/package.json"
|
|
# - "packages/backend/package.json"
|
|
|
|
gitlab:
|
|
url: "https://gitlab.example.com" # or env CI_SERVER_URL
|
|
token: "" # env GITLAB_TOKEN (never commit this)
|
|
project: "" # env CI_PROJECT_ID or CI_PROJECT_PATH
|
|
|
|
github:
|
|
token: "" # env GITHUB_TOKEN (never commit this)
|
|
repo: "" # "owner/repo" format
|
|
```
|
|
|
|
### Environment variables
|
|
|
|
| Variable | Used for |
|
|
|--------------------|-----------------------------------|
|
|
| `GITLAB_TOKEN` | GitLab API auth + HTTPS push auth |
|
|
| `CI_SERVER_URL` | GitLab instance URL |
|
|
| `CI_PROJECT_ID` | GitLab project identifier (numeric) |
|
|
| `CI_PROJECT_PATH` | GitLab project identifier (fallback) |
|
|
| `GITHUB_TOKEN` | GitHub API auth |
|
|
|
|
When both `github.*` and `gitlab.*` are configured, GitHub takes precedence.
|
