-# CLAUDE.md
-
-This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
-
-## What this port is
-
-An OpenBSD port for [mapforge](https://github.com/mapforge-org/mapforge), a self-hosted web GIS application. It is a Ruby on Rails 8.1 app backed by MongoDB and Redis, with MapLibre GL JS on the frontend.
-
-- No upstream releases — the port tracks a git snapshot (`GIT_COMMIT` + `SNAP` in Makefile)
-- To update to a newer commit: change `GIT_COMMIT` and `SNAP`, then run `doas make makesum`
-
-## Build commands
-
-```sh
-doas make fetch          # download source tarball from GitHub
-doas make patch          # extract and apply patches
-doas make build          # bundle install + bootsnap precompile
-doas make fake           # stage into WRKINST
-doas make package        # create the .tgz package
-doas make install        # install from package
-doas make clean=all      # full clean (use instead of make clean)
-```
-
-Run from `/usr/ports/mystuff/geo/mapforge/`.
-
-## Gem dependency handling
-
-This port has no cargo-style bundler module in OpenBSD ports infrastructure. Two approaches:
-
-**Development (network access):** `do-build` calls `bundle install` which fetches gems from rubygems.org and git. Requires network access during the build phase — acceptable for local development.
-
-**Proper offline build:** Pre-generate a vendor cache and add it as a distfile:
-
-```sh
-# After make extract, in WRKDIST:
-bundle _4.0.3_ config set --local without "development test"
-bundle _4.0.3_ package --all --all-platforms --no-install
-tar czf ${DISTDIR}/mapforge-gems-20260322.tar.gz vendor/cache/
-```
-
-Then add `DISTFILES += mapforge-gems-${SNAP}.tar.gz` to the Makefile, extract it in `post-extract` into `${WRKSRC}/vendor/cache/`, and use `bundle install --local` in `do-build`.
-
-Two Gemfile entries use git sources (not rubygems.org):
-- `gpx` from `https://github.com/digitaltom/gpx` (Ruby 4.0 fork)
-- `net-pop` from `https://github.com/ruby/net-pop`
-
-These will be fetched by bundler during build. For a fully offline build, vendor them too via `bundle package --all`.
-
-## Ruby version
-
-Tied to Ruby 4.0 (`MODRUBY_REV = 4.0`). The Gemfile enforces `ruby "4.0.0"` and the Gemfile.lock was generated with bundler 4.0.3 (built into Ruby 4.0).
-
-Relevant paths once ruby40 is installed:
-- `${LOCALBASE}/bin/ruby40`
-- `${LOCALBASE}/bin/bundle40`
-- `${LOCALBASE}/bin/gem40`
-
-## C extension gems
-
-Three gems compile native extensions at `bundle install` time:
-- **rgeo** — geospatial types; optionally links against GEOS (not required)
-- **rgeo-proj4** — coordinate projections; links against `libproj` (`devel/proj`)
-- **rszr** — image resizing; links against `MagickCore-6.Q16`, `MagickWand-6.Q16` (`graphics/ImageMagick`)
-
-This makes the package architecture-dependent (no `PKG_ARCH=*`).
-
-## Runtime services
-
-The app needs these running before starting:
-- `mongod` from `databases/mongodb/80`
-- `redis-server` from `databases/redis`
-
-Start with `rcctl start mongod redis mapforge`.
-
-## Installation layout
-
-| Path | Contents |
-|---|---|
-| `${PREFIX}/share/mapforge/` | Application code + vendored gems |
-| `${LOCALSTATEDIR}/mapforge/log/` | Rails logs |
-| `${LOCALSTATEDIR}/mapforge/storage/` | Active Storage uploads |
-| `${LOCALSTATEDIR}/mapforge/tmp/` | Pids, sockets, cache |
-| `${PREFIX}/share/examples/mapforge/mapforge.rc` | rc.d startup script template |
-
-Copy `mapforge.rc` to `/etc/rc.d/mapforge` and enable with `rcctl enable mapforge`.
-
-## Environment variables
-
-Required in production:
-- `SECRET_KEY_BASE` — Rails secret (generate with `bundle exec rails secret`)
-- `RAILS_ENV=production`
-
-Optional OAuth login:
-- `GITHUB_CLIENT_ID` / `GITHUB_CLIENT_SECRET`
-- `GOOGLE_CLIENT_ID` / `GOOGLE_CLIENT_SECRET`
-- `OSM_CLIENT_ID` / `OSM_CLIENT_SECRET`
-
-## PLIST
-
-The PLIST placeholder needs to be replaced after a successful build:
-
-```sh
-doas make fake
-doas make update-plist
-```
