A simple command-line utility to extract the entities string from a Quake 2 map file.
Binary Space Partitioning maps (.bsp) contain a blog of text containing the metadata for each game object (entity). Their class, location, direction, and various other attributes are included.
To build for your current system:
# go build q2entities.go
To build for another OS or ARCH (ex: 32bit windows):
# GOOS=windows GOARCH=386 CGO_ENABLED=0 go build q2entities.go
# q2ents [-c] <map.bsp>
The -c flag will force a sorted count of each entity. If this flag is missing, the entire entity block will be printed to STDOUT.
