## Development

`flake.nix` defines a development shell that has everything you'll need. To enter, run

```
nix develop
```

The rest of this section assumes you're in the dev shell.

### Running Postgres

`scripts/with-db $COMMAND` will create a Postgres cluster in a temporary directory with the credentials `user=yore-test dbname=yore-test port=5433`, start the Postgres server, run `$COMMAND` and then stop the Postgres erver.
On Linux, you need to have write permissions vor `/var/run/postgresql` to run it.
You can use this to run the tests in an entirely fresh database, e.g.:

```
scripts/with-db cabal test
```

You can also use it to run a database for development by choosing a `$COMMAND` that runs until you quit it, e.g.

```
BASE_DIR=./pgdata scripts/with-db psql "dbname=yore-test port=5433 user=yore-test"
```

By setting `$BASE_DIR` you can persist the database for later runs.

- It seems like the jpgs are generated on demand when the corresponding overview page is hit
    - So we're gonna do the PDFs after all
    - Let's hope we can deduce the PDF path from the link
    - And also that the PDFs aren't generated on demand as well.
      - They are actually

## TODO
