gopath

A wrapper for go related command which set GOPATH dynamically.

Overview

For some reason, one needs to build/get/run go programs out of his main $GOPATH occasionally, or do not want to set an all-in-one static $GOPATH at all.

This program can set $GOPATH to the first directory it found from current working directory towards root which contains a subdirectory called src. If there is already a $GOPATH in environment, gopath will respect it and do nothing. The following table explains the effect of $GOPATH according to $PWD.

$PWD $GOPATH
/path/to/project/src /path/to/project
/tmp/proj/src/foo /tmp/proj

Installation

Build

go get go.papla.net/gopath

gopath is go-getable, you just need to put it into your $PATH after build.

Replace the original binary

gopath will treat argv[0] as the original name if it not named "gopath", otherwise argv[1]. So you can either make a symlink or use shell alias.

e.g., using symlink:

ln -s /path/to/gopath /path/go

and using shell alias:

alias go = 'gopath go'

Setup origin

Two methods are supported currently, using a config file(recommended) or rename the origin.

  1. Modify gopathrc.sample and save it into one of the following location:

    • $XDG_CONFIG_HOME/gopathrc
    • $HOME/.config/gopathrc
    • $HOME/.gopathrc

  2. rename the origin foo to foo.bin, e.g. mv go go.bin.

Issue

Do not support windows yet.
