The project is in Work in Progress (WIP) state. A lot of functionality is still missing.
About
gomirror is a CLI mirror ranker that its main goal is to rank or find the best mirror for a Linux distribution. Although it can be extended to be used as a more general ranker for mirrors/servers.
It is build with usability, extensibility, and performance in mind. It can quickly make thousands of requests with the power of Goroutines, to all servers in parallel. Its inputs and outputs are JSON-modeled, to allow for defined but extensible input data and results. As a CLI tool it will display any results in the standard output by default, but with the correct flag it can also output them in various formats. You can find the expected inputs/outputs for the various supported formats in the inputs/in.template.* and outputs/out.template.* directories respectively.
