Paths and URIs

The default behaviour for the wof command is to assume that all the URIs it is passed are paths on the local computer.

That being said all the tool also "expand" each path using the uris.ExpandURIsWithCallback method which allows for more sophisticated behaviour in the future.

Expansions

Currently there is only two supported "expansions":

1. Treating bare numbers as Who's On First IDs, resolving them to their relative path and looking for that file in a parent "data" directory inside the current working directory. Basically it's a shortcut for resolving a Who's On First record to its GeoJSON representation inside a whosonfirst-data repository.
2. URIs prefixed with repo:// will be treated as a whosonfirst/go-whosonfirst-iterate/v2 "repo" emitter URI and all the files in that repository will be processed.

Eventually there may be other "expansions" most notably support for the Go ./... syntax to process all the Who's On First records in the current working directory.

Advanced

Build tags

Features and functionality are enable through the use of (Go language) build tags. By default the proverbial "kitchen sink" (meaning all features and functionality) is enabled but you can compile your own more limited copy of the wof through the use of no_{FEATURE} build tags.

For example to build the wof command line tool without suport for the whosonfirst/go-writer-geoparquet package (which would shave about 20MB off the size of the final binary) you would do this:

$> go build -mod vendor -ldflags="-s -w" -tags no_writer_geoparquet -o bin/wof cmd/wof/main.go
