Automatically add the current directory to the GOPATH when changing into it

.bash_profile

# GOPATH helper

goPathFile="$HOME/.gopathsrc"

if [ -f "$goPathFile" ]; then
    source "$goPathFile"
fi

.gopathsrc

CHECK_FILENAME=.gopath

setGoPath() {
  if [ -f "$PWD/$CHECK_FILENAME" ]; then
    if ! [[ "$GOPATH" =~ (^|:)"$PWD"(:|$) ]]; then
      echo "Adding $PWD to GOPATH"
      export GOPATH=$GOPATH:$PWD
      echo $GOPATH
    fi
  fi
}

if [ "$PROMPT_COMMAND" != "*setGoPath*" ]; then
  export PREV_PROMPT_COMMAND=$PROMPT_COMMAND
  export PROMPT_COMMAND="$PROMPT_COMMAND; setGoPath"
fi

@minherz There is no downside to having repeated elements in the path while foregoing the complexity of maintaining the unique elements you are suggesting.

As you wish. I would not dispute about the "foregoing maintenance complexity" because it depends on the observer. Mind though that the longer the path the more time is required to process things and more chances for ambiguity.
