# scrabble-dictionary

Versioned **dictionary artifacts** for the Scrabble game backend: the word-list sources and
the build pipeline that produces the dictionary DAWGs, published as a **release artifact**
(the DAWGs are data, not a Go module).

The build uses the published
[`scrabble-solver`](https://gitea.iliadenisov.ru/developer/scrabble-solver) `dictdawg`/`wordlist`
packages (pinned in `go.mod`) over `github.com/iliadenisov/{dafsa,alphabet}` (v1.1.0), so the
on-disk format and letter indexing match the running backend **exactly** — there is no index
drift, because the backend pins the same `dafsa`/`alphabet`. The DAWGs this repo builds are
byte-identical to the solver's committed test fixtures.

## Artifact

`make dawg` builds three DAWGs into `dawg/`:

| file | variant | source |
| --- | --- | --- |
| `en_sowpods.dawg` | English (SOWPODS) | `dictionaries/english/sowpods.txt` |
| `ru_scrabble.dawg` | Russian Scrabble | `dictprep/russian/scrabble.txt` |
| `ru_erudit.dawg` | Эрудит | the Russian list with Ё→Е folded (`dictprep/fold_yo.py`) |

The CI (`.gitea/workflows/build.yaml`) builds them on every push/PR and, on a `vX.Y.Z` tag,
packages them flat into `scrabble-dawg-<tag>.tar.gz` and attaches it to the Gitea release. The
backend deploy unpacks that tarball into `BACKEND_DICT_DIR`; **one semver label versions the
whole set** (additive — a new version is a new release, never breaking a running backend).

## Sources / provenance

- **English:** `dictionaries/english/sowpods.txt`, vendored from
  [`kamilmielnik/scrabble-dictionaries`](https://github.com/kamilmielnik/scrabble-dictionaries).
- **Russian:** `dictprep/russian/scrabble.txt`, derived from the Russian academic orthographic
  dictionary by the tooling under `dictprep/` (see `dictprep/README.md`). Only the prepared word
  list is vendored; the heavy upstream source (the orfo PDF/text) is not.

## Build

```sh
make dawg     # -> dawg/{en_sowpods,ru_scrabble,ru_erudit}.dawg
```

Requires Go (module deps fetched with `GOPRIVATE=gitea.iliadenisov.ru/*`, exported by the
Makefile) and `python3` (for the Ё→Е fold).
