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).

Installation

Install Binary from GitHub Releases

https://github.com/haya14busa/gopkgs/releases

go get

go get -u github.com/haya14busa/gopkgs/cmd/gopkgs

SYNOPSIS

$ gopkgs -h
Usage of gopkgs:
  -f string
        alternate format for the output using the syntax of template package. e.g. {{.Name}};{{ImportPathShort}}
  -fullpath
        output absolute file path to package directory. ("/usr/lib/go/src/net/http")
  -include-name
        fill Pkg.Name which can be used with -f flag
  -short
        output vendorless import path ("net/http", "foo/bar/vendor/a/b") (default true)


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")
    }

Vim

Sample usage of gopkgs in Vim: open godoc and import with vim-go and fzf

augroup gopkgs
  autocmd!
  autocmd FileType go command! -buffer Import exe 'GoImport' fzf#run({'source': 'gopkgs'})[0]
  autocmd FileType go command! -buffer Doc exe 'GoDoc' fzf#run({'source': 'gopkgs'})[0]
augroup END

Above Vim script is just a sample and isn't robust. I'm planning to create or contribute Vim plugins to include the same feature.

- unite.vim (and vim-go) intergration for importing package or opening godoc in Vim.
