ctags / godeps

godeps:

  • prints the source dependencies of named packages

sending godeps output to ctags, the tags file automatically has tokens from all of my dependent packages.

add to .bashrc.

goctags () {
    godeps ./... \
        | awk -v GOPATH=$GOPATH '{print GOPATH "/src/" $1}' \
        | xargs ctags -R .;
}
