Written in Zig with zero external dependencies, it produces clean Markdown changelogs categorized by type. ## Features * Fast compiled binary with zero external dependencies (pure Zig stdlib) * Generates Markdown changelogs from GitHub data automatically * Categorizes entries by labels: Features, Bug Fixes, and Other * Links to pull requests, issues, and contributors * Smart token resolution with automatic fallback chain * Tag-based filtering (--since-tag and --until-tag) * Label exclusion support (--exclude-labels) * Customizable output filename and path * Works with any public or private GitHub repository * Integration tests verify core logic ## Command-Line Options * `--repo` (required): GitHub repository in format [org]/[repo]. Example: github/cli * `--token` (optional): GitHub API token. Falls back to env vars or gh CLI * `--output` (optional): Output file path. Default: CHANGELOG.md * `--since-tag` (optional): Start from this tag/version * `--until-tag` (optional): End at this tag/version * `--exclude-labels` (optional): Comma-separated labels to exclude * `--help` or `-h`: Show help message ## Authentication The tool automatically retrieves a GitHub token in this order: 1) --token flag, 2) GITHUB\_TOKEN env var, 3) GH\_TOKEN env var, 4) gh auth token command. Required for private repos and recommended for higher rate limits. ## Usage Examples Basic: chlogr --repo owner/repository With output: chlogr --repo owner/repository --output HISTORY.md With token: chlogr --repo owner/repository --token ghp\_xxxxxxxxxxxx Tag range: chlogr --repo owner/repository --since-tag v1.0.0 --until-tag v2.0.0 Exclude labels: chlogr --repo owner/repository --exclude-labels duplicate,wontfix ## Technical Details * Built with Zig 0.15+ for native performance * Zero external dependencies - Zig stdlib only * Single portable executable * Cross-platform (Linux, macOS, Windows) * Modular architecture: CLI parsing, token resolution, GitHub API, changelog generation, markdown formatting ## Output Format Generated changelogs include release/version headers with links, release dates, categorized entries (Features, Bug Fixes, Other), PR/issue numbers with links, contributor usernames with profile links, and clean Markdown formatting. ## Installation Via snap: sudo snap install chlogr From source: git clone && cd chlogr && zig build ## Requirements * GitHub account (for private repos or higher rate limits) * GitHub API token (optional but recommended) * Zig 0.15+ for building from source ## Links Source: Issues: ### Package name * chlogr --- ### License * MIT --- ### Last updated * 24 March 2026 - latest/stable * 12 October 2026 - latest/edge --- ### Donations * [buymeacoffee.com](https://buymeacoffee.com/christianhelle "https://buymeacoffee.com/christianhelle") * [github.com/sponsors/christianhelle](https://github.com/sponsors/christianhelle "https://github.com/sponsors/christianhelle") * [github.com/sponsors/christianhelle](https://github.com/sponsors/christianhelle "https://github.com/sponsors/christianhelle") --- ### Source code * [github.com/sponsors/christianhelle](https://github.com/sponsors/christianhelle "https://github.com/sponsors/christianhelle") --- ### Report a bug * [github.com/sponsors/christianhelle](https://github.com/sponsors/christianhelle "https://github.com/sponsors/christianhelle") --- ##### Report a Snap Store violation * [Report this Snap](https://snapcraft.io/install/chlogr/rhel#report-snap-modal) --- ## Enable snaps on Red Hat Enterprise Linux and install Changelog Generator Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully. Snaps are discoverable and installable from the [Snap Store](https://snapcraft.io/store), an app store with an audience of millions. ### Enable snapd Snap is available for [Red Hat Enterprise Linux (RHEL) 8](https://www.redhat.com/en/enterprise-linux-8) and RHEL 7, from the 7.6 release onward. The packages for RHEL 7, RHEL 8, and RHEL 9 are in each distribution’s respective [Extra Packages for Enterprise Linux](https://fedoraproject.org/wiki/EPEL) (EPEL) repository. The instructions for adding this repository diverge slightly between RHEL 7, RHEL 8 and RHEL 9, which is why they’re listed separately below. The EPEL repository can be added to **RHEL 9** with the following command: ``` sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm sudo dnf upgrade ``` The EPEL repository can be added to **RHEL 8** with the following command: ``` sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm sudo dnf upgrade ``` The EPEL repository can be added to **RHEL 7** with the following command: ``` sudo rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm ``` Adding the *optional* and *extras* repositories is also recommended: ``` sudo subscription-manager repos --enable "rhel-*-optional-rpms" --enable "rhel-*-extras-rpms" sudo yum update ``` Snap can now be installed as follows: ``` sudo yum install snapd ``` Once installed, the *systemd* unit that manages the main snap communication socket needs to be enabled: ``` sudo systemctl enable --now snapd.socket ``` To enable *classic* snap support, enter the following to create a symbolic link between `/var/lib/snapd/snap` and `/snap`: ``` sudo ln -s /var/lib/snapd/snap /snap ``` Either log out and back in again or restart your system to ensure snap’s paths are updated correctly. ### Install Changelog Generator To install Changelog Generator, simply use the following command: ``` sudo snap install chlogr ``` ### Other popular snaps… [See more...](https://snapcraft.io/search?categories=featured) [See more in Featured](https://snapcraft.io/search?categories=featured) ### More things to do… #### [Get the snap store](https://snapcraft.io/snap-store) Browse and find snaps from the convenience of your desktop using the snap store snap. #### [Learn more about snaps](https://snapcraft.io/docs) Interested to find out more about snaps?
