This plugin provides a Prometheus `/metrics` endpoint and an extensible way to add your own metrics in third-party plugins using hooks. It adds some default metrics like number of active accounts, number of articles, comments, and plugin status. The default metrics can be activated/deactivated in the plugin settings.
- Dedicated plugin settings under 'Settings/Metrics' menu
- Extensible by other plugins using `wp_prometheus_collect_metrics` action hook
- License management integration
### Key Fact: 100% AI-Generated
This project is proudly **"vibe-coded"** using Claude.AI - the entire codebase was created through AI assistance.
## Temporary Roadmap
**Note for AI Assistants:** Clean this section after the specific features are done or new releases are made. Effective changes are tracked in `CHANGELOG.md`. Do not add completed versions here - document them in the Session History section at the end of this file.
- **License Client:** `magdev/wc-licensed-product-client` Have a look at <https://src.bundespruefstelle.ch/magdev/wp-fedistream> for a working admin integration
- Wrong: Running zip from inside the plugin directory creates files at root level
- **CRITICAL**: Exclude symlinks explicitly - zip follows symlinks by default
- Always use `-x "wp-prometheus/wp-core" -x "wp-prometheus/wp-core/*" -x "wp-prometheus/wp-plugins" -x "wp-prometheus/wp-plugins/*"` to exclude development symlinks
- Otherwise the entire linked directory contents will be included in the package
- Exclusion patterns must match the relative path structure used in zip command
- Always verify the package structure with `unzip -l` before distribution
- Check all files are prefixed with `wp-prometheus/`
- Verify main file is at `wp-prometheus/wp-prometheus.php`
- Check for duplicate entries (indicates multiple builds in same archive)
- Test installation on the minimum supported PHP version before final deployment
- Releases are stored in `releases/` including checksums
- Track release changes in a single `CHANGELOG.md` file
- Bump the version number to either bugfix release versions or on new features minor release versions
- **CRITICAL**: WordPress reads version from TWO places - BOTH must be updated:
1. Plugin header comment `Version: x.x.x` - WordPress uses THIS for admin display
2. PHP constant `WP_PROMETHEUS_VERSION` (line ~28) - Used internally by the plugin
- If only the constant is updated, WordPress will show the old version in Plugins list
**Important Git Notes:**
- Default branch while development is `dev`
- Create releases from branch `main` after merging branch `dev`
- Tags should use format `vX.X.X` (e.g., `v1.1.22`), start with v0.0.1
- Use annotated tags (`-a`) not lightweight tags
- Commit messages should follow the established format with Claude Code attribution
-`.claude/settings.local.json` changes are typically local-only (stash before rebasing)
**CRITICAL - Release Workflow:**
On every new version, ALWAYS execute this complete workflow:
```bash
# 1. Commit changes to dev branch
git add <files>
git commit -m "Description of changes (vX.X.X)"
# 2. Merge dev to main
git checkout main
git merge dev --no-edit
# 3. Create annotated tag
git tag -a vX.X.X -m "Version X.X.X - Brief description"
# 4. Push everything to origin
git push origin dev main vX.X.X
# 5. Switch back to dev for continued development
git checkout dev
```
Never skip any of these steps. The release is not complete until all branches and the tag are pushed to origin.
#### What Gets Released
- All plugin source files
- Compiled vendor dependencies
- Translation files (.mo compiled from .po)
- Assets (CSS, JS)
- Documentation (README, CHANGELOG, etc.)
#### What's Excluded
- Git metadata (`.git/`)
- Development files (`.vscode/`, `.claude/`, `CLAUDE.md`, `wp-core`, `wp-plugins`)
- Logs and cache files
- Previous releases
-`composer.lock` (but `vendor/` is included)

**For AI Assistants:**
When starting a new session on this project:
1. Read this CLAUDE.md file first
2. Semantic versioning follows the `MAJOR.MINOR.BUGFIX` pattern
3. Check git log for recent changes
4. Verify you're on the `dev` branch before making changes
5. Run `composer install` if vendor/ is missing
6. Test changes before committing
7. Follow commit message format with Claude Code attribution
8. Update this session history section with learnings
9. Never commit backup files (`*.po~`, `*.bak`, etc.) - check `git status` before committing
10. Follow markdown linting rules (see below)
Always refer to this document when starting work on this project.
### Markdown Linting Rules
When editing CLAUDE.md or other markdown files, follow these rules to avoid linting errors:
1.**MD031 - Blank lines around fenced code blocks**: Always add a blank line before and after fenced code blocks, even when they follow list items. Example of correct format:
- **Item label**:
(blank line here)
\`\`\`php
code example
\`\`\`
(blank line here)
2.**MD056 - Table column count**: Table separators must have matching column counts and proper spacing. Use consistent dash lengths that match column header widths.
3.**MD009 - No trailing spaces**: Remove trailing whitespace from lines
4.**MD012 - No multiple consecutive blank lines**: Use only single blank lines between sections
5.**MD040 - Fenced code blocks should have a language specified**: Always add a language identifier to code blocks (e.g., `txt`, `bash`, `php`). For shortcode examples, use `txt`.
6.**MD032 - Lists should be surrounded by blank lines**: Add a blank line before AND after list blocks, including after bold labels like `**Attributes:**`.
7.**MD034 - Bare URLs**: Wrap URLs in angle brackets (e.g., `<https://example.com>`) or use markdown link syntax `[text](url)`.
8.**Author section formatting**: Use a heading (`### Name`) instead of bold (`**Name**`) for the author name to maintain consistent document structure.
