To merge a few swagger YAML files into one.
Install Go if you don't have one.
https://golang.org/doc/install
Install the command line tool first.
go get github.com/g3co/go-swagger-merger
The command below will merge /data/swagger1.yaml /data/swagger2.yaml and save result file in the /data/swagger.yaml. The library supports more than two files to merge. You can add more paths to the list /data/swagger3.yaml, /data/swaggerN.yaml.
go-swagger-merger -o /data/swagger.yaml /data/swagger1.yaml /data/swagger2.yaml
Attention. The order of the files is essential, and the following file overwrites the same fields from the previous file.
