navigate to a go project directory easily using `goto` command

goto.sh

#!/bin/bash

if [ -z "$@" ]; then
    echo "Usage: goto project-name"
    return
fi

search_path=$GOPATH/src/

for i in {1..3}; do
    len=${#search_path}
    project_dir=$(find $GOPATH/src -maxdepth $i -mindepth $i | cut -c$len- | grep -m 1 $1)
    if [ ! -z "$project_dir" ] ; then
        cd $search_path/$project_dir
        break
    fi
done 

Usage:

• Download the above script (goto.sh):

  wget https://goo.gl/BMfbny
  

• Add the following line to your ~/.zshrc or ~/.bashrc if you're not hanging out with the cool kids yet:

  alias goto=". /path_to_go_to/goto.sh"
  

  IMPORTANT: The . in the beginning is MANDATORY. It causes the script to be run in the current environment, giving it the ability to change the current working directory using cd
• Now you can do

  $ goto github      # cd $GOPATH/src/github.com
  $ goto colonelmo   # cd $GOPATH/src/github.com/colonelmo
  $ goto cobra       # cd $GOPATH/src/github.com/spf13/cobra 
  

exit 0 instead of return in usage clause. 😃

@remohammadi I'll let you try that to find out why it would not work.

Things would be cleaner if you didn't source the script every time. Instead of sourcing a script that then executes you could write:

 # goto.sh here
 function goto
 {
     cd $(find $GOPATH/src -type d  | egrep $* )
 }

Then usage would be :

• Add ". ~/path/to/go.sh" to the end of ~/.bash_profile, or your zsh init file.

(Obviously I simplified your script, but not by too much I hope.)

Very helpful 👍
