go-google-photos-api

I got frustrated not having official google photos api, so I code generated mine, based on the last version of the discovery document : https://photoslibrary.googleapis.com/$discovery/rest?version=v1

Client code based on googleapis last version, before it got removed : https://github.com/googleapis/google-api-go-client/blob/10267775243d8c189ce96dc29556e9673459e6f3/photoslibrary/v1/photoslibrary-gen.go

using official generator

After finishing writing this generator I found out google already made one.

go install google.golang.org/api/google-api-go-generator
~/go/bin/google-api-go-generator -api_json_file photoslibrary/v1/photoslibrary-api.json -gendir .
