Functions

func CheckOrDownloadProtoc

func CheckOrDownloadProtoc(path, version string) (string, error)

CheckOrDownloadProtoc downloads protoc to the specified path, unless it's already been downloaded. If no path is provided, it uses an OS-appropriate user cache. If the version is not specified, the latest version is fetched from GitHub. If both version and path are specified and a file already exists at the path, it checks whether the output of `protoc --version` is an exact match.

Note that this code is safe for concurrent use between multiple goroutines or processes, since it uses a lock file on disk.
