gopkgs - List Go packages FAST by using the same implementation as goimports

gopkgs outputs list of importable Go packages.

By using the same implementation as goimports, it's faster than go list ... and it also has -f option.

gopkgs cares .goimportsignore which was introduced by golang/go#16386 since it uses the same implementation as goimports.

Sample usage of gopkgs with other tools like godoc and filtering tools (peco).

Here I modified some code, add some functionnal code for gomod support , also remove many code for some functionnal are unnecessary when we writing code with vim/nvim.

Installation

Install Binary from GitHub Releases

https://github.com/3Xpl0it3r/gopkgs/releases

go get

go get -u github.com/3Xpl0it3r/gopkgs/cmd/gopkgs

SYNOPSIS

In fact we don't need this to list all importpakcage. You may need use go list ./... for this ; This tools should be used with neovim for go list are too slow.

➜  gopkgs git:(master) gopkgs -h
Usage of gopkgs:
  -include-name
    	fill Pkg.Name which can be used with -f flag
  -no-vendor
    	exclude vendor dependencies except under workDir 

Use -f to custom the output using template syntax. The struct being passed to template is:
	type Pkg struct {
		Dir             string // absolute file path to Pkg directory ("/usr/lib/go/src/net/http")
		ImportPath      string // full Pkg import path ("net/http", "foo/bar/vendor/a/b")
		ImportPathShort string // vendorless import path ("net/http", "a/b")

		// It can be empty. It's filled only when -include-name flag is true.
		Name string // package name ("http")
	}
