tinysemver 2.0.7

Tiny Semantic Versioning (SemVer) library, that doesn't depend on 300K lines of JavaScript

TinySemVer is a minimalistic Semantic Versioning package for projects following Conventional Commits in a single short Python file. In plain English, if your commit messages look like feat: add new feature or fix: bugfix, this package will automate releasing new "GIT tags" based on the commit messages. Here is how to integrate it into your project CI:

$ pip install tinysemver
$ tinysemver --dry-run --verbose
> Current version: 1.2.2
> Next version: 1.3.0

The --dry-run flag will only print the next version without changing any files. Great for pre-release CI pipelines.

Usage Details for the Command Line Interface

If you need more control over the default specification, here are more options you can run against the files in this repository:

# This won't push
$ tinysemver --verbose \
    --major-verbs 'breaking,break,major' \
    --minor-verbs 'feature,minor,add,new' \
    --patch-verbs 'fix,patch,bug,improve,docs,make' \
    --changelog-file 'CHANGELOG.md' \
    --version-file 'VERSION' \
    --update-version-in 'pyproject.toml' '^version = "(\d+\.\d+\.\d+)"' \
    --github-repository 'ashvardanian/tinysemver'
# Revert to the previous commit
$ git reset --soft HEAD~1                         

It's recommended to use strict version matching with \d+\.\d+\.\d+ instead of a generic wildcard like .*, but both would work. Here is an example of passing even more parameters for a project like stringzilla:

$ tinysemver --verbose \
    --major-verbs 'breaking,break,major' \
    --minor-verbs 'feature,minor,add,new' \
    --patch-verbs 'fix,patch,bug,improve,docs,make' \
    --changelog-file 'CHANGELOG.md' \
    --version-file 'VERSION' \
    --update-version-in 'pyproject.toml' '^version = "(\d+\.\d+\.\d+)"' \
    --update-version-in 'package.json' '"version": "(.*)"' \
    --update-version-in 'CITATION.cff' '^version: (.*)' \
    --update-major-version-in 'include/stringzilla/stringzilla.h' '^#define STRINGZILLA_VERSION_MAJOR (.*)' \
    --update-minor-version-in 'include/stringzilla/stringzilla.h' '^#define STRINGZILLA_VERSION_MINOR (.*)' \
    --update-patch-version-in 'include/stringzilla/stringzilla.h' '^#define STRINGZILLA_VERSION_PATCH (.*)' \
    --github-repository 'ashvardanian/stringzilla' \
    --push
> Current version: 1.2.2
> ? Commits since last tag: 3                   # Only in verbose mode

> + "version": "1.3.0"                          # Only in verbose mode
> Will update file: pyproject.toml:7
> - version = "1.2.2"                           # Only in verbose mode
> + version = "1.3.0"                           # Only in verbose mode
> Will update file: CITATION.cff:7

> Appending to changelog file: CHANGELOG.md
> = skipping 250 lines                          # Only in verbose mode
> + adding 30 lines                             # Only in verbose mode

Alternatively, you can just ask for --help:

Usage Details for the GitHub CI Action

TinySemVer can be easily integrated into your GitHub Actions CI pipeline. Assuming the differences between YAML and shell notation, some arguments are passed in a different form, like --update-version-in.

name: Release

on:
  push:
    branches: [ main ]

jobs:
  semver:
    runs-on: ubuntu-latest

    steps:
    - name: Checkout
      uses: actions/checkout@v4
      with:
        persist-credentials: false # Only if main branch if protected

    - name: Run TinySemVer
      uses: ashvardanian/tinysemver@v2.0.1
      with:
        major-verbs: 'breaking,break,major'
        minor-verbs: 'feature,minor,add,new'
        patch-verbs: 'fix,patch,bug,improve,docs,make'
        changelog-file: 'CHANGELOG.md'
        version-file: 'VERSION'
        update-version-in: 'pyproject.toml:version = "(.*)"' # Use colon instead of space
        git-user-name: 'GitHub Actions'
        git-user-email: '[e-mail]'
        github-token: ${{ secrets.GITHUB_TOKEN }}
        verbose: 'true'
        push: 'true'
        create-release: 'true'
        dry-run: 'false'

  publish:
    needs: semver # Depends on the previous job
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v4
        with:
          ref: main # Take the most recent updated version

Every team has a different workflow, but a common pattern is to have one release.yml for the main branch and another prerelease.yml for the main-dev branch used as a staging area. The latter would run with dry-run: 'true' and push: 'false' to prevent pushing changes to the main repository. The create-release flag is optional and can be set to false if you don't want to create a new release on GitHub. If you need to update the version in multiple files, pass a multiline string with the | operator:

        update-version-in: |
          pyproject.toml:version = "(.*)"
          package.json:"version": "(.*)"
          CITATION.cff:version: "(.*)"

For examples, consider checking StringZilla, USearch, and other libraries using TinySemVer.

Security Considerations

If your default branch is protected with a "pull request before merging" rule:

1. A repository-scoped Personal Access Token (PAT) is required to push to the branch.
2. Set persist-credentials: false in the actions/checkout step.

Also keep in mind:

• The default GITHUB_TOKEN cannot be used with protected branches.
• Using a PAT instead of GITHUB_TOKEN poses security risks:
  • Workflows from any branch can access secret variables.
  • This could allow non-protected branches to use elevated permissions.
• Mitigation:
  • Use a fine-grained PAT with minimal necessary permissions.
  • Prefer the pull_request workflow trigger, which limits permissions.
  • Be cautious: users with write access could still potentially exploit workflows to expose the PAT.

[!TIP] Always follow the principle of least privilege when setting up tokens and permissions.

For more information on CI configurations and pushing changes in GitHub Actions, see the semantic-release GitHub Actions guide.

Why Create Another SemVer Tool?

In the past I was using semantic-release for my 10+ projects. At some point, a breaking change in the dependencies broke all my projects CI pipelines for a month, affecting dozens of tech companies using those libraries. I felt miserable trying to trace the issue and reluctant to go through 363K lines of low-quality JavaScript code to find the bug. Yes, it's 363K lines of code:

$ .../node_modules$ cloc .
   10751 text files.
    7809 unique files.                                          
    3498 files ignored.

What's Missing?

• Optional commit scopes, like feat(scope): add new feature. Doesn't make sense for most projects.
• Pre-release versions, like 1.2.3-alpha.1. Not needed for most projects.
• GenAI.

For reference, according to SemVer 2.0, all following versions are valid: 1.1.2-prerelease+meta, 1.1.2+meta, 1.1.2+meta-valid, 1.0.0-alpha, 1.0.0-beta, 1.0.0-alpha.beta.1, 1.0.0-alpha.1, 1.0.0-alpha0.valid, 1.0.0-alpha.0valid, 1.0.0-alpha-a.b-c-somethinglong+build.1-aef.1-its-okay, 1.0.0-rc.1+build.1, 2.0.0-rc.1+build.123, 1.2.3-beta, 10.2.3-DEV-SNAPSHOT, 1.2.3-SNAPSHOT-123, 2.0.0+build.1848, 2.0.1-alpha.1227, 1.0.0-alpha+beta, 1.2.3----RC-SNAPSHOT.12.9.1--.12+788, 1.2.3----R-S.12.9.1--.12+meta, 1.2.3----RC-SNAPSHOT.12.9.1--.12, 1.0.0+0.build.1-rc.10000aaa-kk-0.1, 1.0.0-0A.is.legal.

Examples

Assembling RegEx queries can be hard. Luckily, there aren't too many files to update in most projects. Below is an example of a pipeline for the USearch project, that has bindings to 10 programming languages. Feel free to add other sources and examples.
