I want to install https://github.com/syohex/emacs-helm-gtags, and here is the installation instruction:
helm-gtags is available on MELPA and MELPA stable
You can install helm-gtags with the following command.
M-x package-install [RET] helm-gtags [RET]
M-x package-install [RET] helm-gtags [RET], I got "no match".
How shall I solve this problem? Thanks.
M-x package-refresh-contents [RET] will stay at "Contacting host: elpa.gnu.org:80" forever, so doesn't seem to solve the problem. Why doesn't finish running?
2) Even without waiting for "Contacting host: elpa.gnu.org:80" to go away, running
helm-gtags still results in "no match".
3) Do I need to add the repository of
helm-gtags somewhere, and what is its repository?
