CI / check (push) Failing after 1m30s
Ruby syntax check, a require_relative "app" smoke load, and JS syntax check on every push/PR. No test suite exists yet, so these are cheap syntax/load checks rather than behavioral tests.

Open http://127.0.0.1:4567. For auto-reload during development, run
|
|
via the `rerun` gem instead:
|
|
|
|
[source,shell]
|
|
----
|
|
bundle exec rerun -- bundle exec puma -C config/puma.rb
|

|
TIP: Browsers apply heuristic caching to static files even without
|
|
explicit cache headers, so an edit to `public/` (or `views/`) can
|
|
appear not to have taken effect on the next reload. Force a real
|
|
reload (e.g. Ctrl/Cmd+Shift+R) if that happens.
|
|
|
|
== Offline map data
|
|
|
|
To enable the offline style, place a PMTiles file at
|
|
`data/offline.pmtiles` (see `docs/architecture.adoc` for how it is
|
|
served and styled). It is not part of the repository — obtain or
|
|
build one locally:
|
|
|
|
* The simplest source is a pre-built extract from
|
|
https://app.protomaps.com[protomaps.com's extract builder] — pick a
|
|
region and download it as `.pmtiles`. Its schema is what
|
|
`protomaps-themes-base` (the styling library used for the offline
|
|
style) expects.
|
|
* To convert some other vector tile source (e.g. an `.mbtiles` file)
|
|
into PMTiles, use the
|
|
https://github.com/protomaps/go-pmtiles[go-pmtiles] CLI:
|
|
`pmtiles convert in.mbtiles data/offline.pmtiles`.
|
|
|
|
Once the file is in place, `GET /api/offline-tiles` reports
|
|
`available: true` and the map defaults to the offline style.
|
|
|
|
== GNSS position (gpsd)
|
|
|
|
The "GNSS" control needs https://gpsd.io[gpsd] running and pointed at
|
|
a receiver (`gpsd /dev/ttyUSB0`, or whatever device the receiver shows
|
|
up as). On openSUSE, `gpsd` is a package with systemd units
|
|
(`gpsd.service` / `gpsd.socket`); on other distributions, check your
|
|
package manager. No app-side configuration is needed — it just
|
|
connects to `127.0.0.1:2947`, gpsd's default port.
|
|
|
|
To test without hardware, feed gpsd a fake NMEA stream over TCP
|
|
instead of a real serial device — gpsd accepts a `tcp://host:port`

`GET /api/gnss/position` should then report the fake fix (Bratislava

Castle, in the sentences above) within a couple of seconds.
|
|
|
|
== Continuous integration
|
|
|
|
`.gitea/workflows/ci.yml` runs on every push/PR against a self-hosted
|
|
Gitea Actions runner: `ruby -c` on every `.rb` file, a `require_relative
|
|
"app"` smoke check that the app loads without error, and `node --check`
|
|
on every file under `public/js/`. There is no test suite yet — these
|
|
are cheap syntax/load checks, not behavioral tests.
