Make erln8 easy to use from Emacs #3

Open bookshelfdave opened 9 years ago

bookshelfdave commented 9 years ago

This is what's needed to use erln8 from Emacs:

(setq load-path (cons  "/Users/joe/.erln8.d/otps/17.5.6/dist/lib/erlang/lib/tools-2.7.2/emacs"
      load-path))
(setq erlang-root-dir "/Users/joe/.erln8.d/otps/17.5.6/dist")
(setq exec-path (cons "/Users/joe/.erln8.d/otps/17.5.6/dist/bin" exec-path))

Is there a way I can remove some of the hardcoded paths?

The idea is that these settings could be pulled from the system default otp version

bookshelfdave commented 9 years ago

[x] provide a command line param to set and get the default version of Erlang
- erln8 --set-default OTP_18.0
- erln8 --get-default OTP_18.0
[ ] upon setting default via the command above, or by the prompt in the build, create an ~/.erln8.d/support/emacs directory with symlinks to:
- dist
- dist/bin
- dist/lib/erlang/lib/tools-2.7.2/emacs making the version #'s go away
[ ] optional: provide a --emacs-config command that displays the elisp you can paste into your .emacs

there should be an elisp fragment that lets you evaluate the output of reo --emacs-config so you don't have to copy/paste and will automatically change when you change your default erlang.
