GPM

Go Package Mapping

Motivation

I personally use a lot of nice libraries in Go, but every time I start a new project I have to go hunting for import paths again!

Enter GPM, a glorified mapping of simple names to go-get imports.

For example, I use urfave/cli for all of my CLI projects. I've used it enough times to remember the import path, but let's say I didn't.
Using either a GPM server or local config, I can instead gpm get cli which finds cli in my map and runs go get github.com/urfave/cli/v2.

Commands

• add - Add a local package
• remove - Remove a local package
• list - List local packages
• config - Change local configuration (GPM server)
• export - Export local packages to JSON
• import - Import JSON to local packages
• get - Get a list of packages
  e.g. gpm get beaver survey toml homedir cli to get all the modules needed for gpm itself (assuming the map resolves to the same packages)

Server

If GPM doesn't find a package locally, it can call out to a configurable gpm server to find a package there.
This makes it much simpler to have a central library of packages rather than exporting and importing between environments.

The import and export commands should work between the CLI and server for easy transitions.
