# pipelines/tech

Publishes tech blog posts from `mikkeli/tech-blogs` to `https://wiki.novoyuuparosk.org`.

- Source-file contract (frontmatter and body conventions): [SCHEMA.md](SCHEMA.md)
- Cross-cutting setup (wiki URL, bot identity, runner, Gitea secrets/variables): [repo root README](../../README.md)

## v1 scope

- YAML frontmatter parsing per [SCHEMA.md](SCHEMA.md)
- Pandoc-based markdown → wikitext body rendering (h1 elements preserved)
- Auto-generated banner (`{{Auto-generated|source=...|commit=<sha>}}`)
- Category injection: `[[Category:Tech blog]]` on every page; `[[Category:Blog:<year>]]` from `date` field; `[[Category:<tag>]]` per tag entry
- No title prefix — pages live at their bare title
- MediaWiki bot API write with idempotency — no-op if wiki content matches generated output
- Files without `wiki.publish: true` silently skipped
- Pages with existing non-auto-generated content skipped (logged to stderr)

## Source repo

Source repo: `mikkeli/tech-blogs` (not yet initialised — pipeline code is ready).

The pipeline triggers on push to `master` and supports `workflow_dispatch` for manual runs.

**Excluded paths** (won't trigger the pipeline):

- `README.md`, `.gitignore`, `.claude/**`

## Invocation

The pipeline runs as a self-contained Gitea Actions workflow in `mikkeli/tech-blogs` (`.gitea/workflows/publish.yml`). It clones this repo at runtime to get the renderer.

Triggers:
- `push` to `master` (path-filtered as above)
- `workflow_dispatch` — manual trigger from the Gitea Actions UI

### Environment (secrets and variables)

| Name | Kind | Source | Purpose |
|---|---|---|---|
| `WIKI_API_URL` | variable | Gitea (cross-cutting) | MediaWiki action API endpoint |
| `WIKI_BASE_URL` | variable | Gitea (cross-cutting) | Wiki base URL |
| `WIKI_BOT_USER` | secret | Gitea (cross-cutting) | Bot login |
| `WIKI_BOT_PASSWORD` | secret | Gitea (cross-cutting) | BotPasswords value |
| `URL_TO_GITEA` | variable | Gitea (cross-cutting) | Gitea instance base URL for cloning |
| `FAPAT` | secret | Gitea (cross-cutting) | Full-Access PAT for cloning private repos |
| `SOURCE_REF` | env (set in workflow) | `github.sha` | Pushed commit SHA, used in banner and edit summary |
| `GITEA_REPO_URL` | env (set in workflow) | composed from vars | Source-file URL base for the banner link |

## Dependencies

Job container: `novoyuuparosk-wiki-runner:latest` (pre-built, stored in the local Docker daemon on the runner host). Bakes in Python 3.12, Pandoc, and all pipeline Python packages — no install steps at job runtime.

See the `Dockerfile` at the repo root and `requirements.txt` in this directory. Rebuild the image after changes to either.

Shared code lives in `lib/wiki.py` (repo root).

## One-off wiki setup

- [ ] **`Template:Auto-generated`** — must exist on the wiki (shared with all pipelines; already created).
