我安装了图阿雷格模式，但它甚至没有显示在 emacs 中

Question

I tried to install the tuareg mode for emacs on Manjaro, but when i open emacs and create a test.ml file, the "tuareg" menu isn't even there and all the commands such as Ctrl c + Ctrl b are undefined, it's as if tuareg wasn't installed.

In order to install the tuareg mode for emacs here is what i've done :

sudo pacman -S emacs
sudo pacman -S opam
opam install ocaml
opam install tuareg
opam init

Everything worked well during the installation so i don't know why it's not working. I guess it's something like emacs isn't linked to the tuareg mode and i need to specify a folder or something like that to find the tuareg mode. But even then i cant't find the .emacs files, so i don't really know what to do.

Answer 1

You're not far from it !

As you guessed, emacs doesn't know that tuareg exists. The simplest way to solve that is to type:

opam install user-setup

You'll need to restart emacs afterwards to load the new configuration.

Answer 2

@PatJ command didn't work for me. I'm on a raspberry pi (pi400) with Twister OS which is based on Raspberry Pi OS. So I try in super user

apt install emacs
apt upgrade
apt install opam
opam install ocaml (which tells me that ocaml is already install)
opam init
opam install user-setup

I have already try with camllight using this script http://judicael.courant.free.fr/2015/02/20/installationcaml.html (a thing with melpa but i don't remember exatly) then Mx list-packages then install tuareg then edit .emacs with (add to list 'load-path "home/pi/.emacs.d/lisp") where lisp is a directory which contain tuareg.el, camldebug.el, tuareg-site-file-el

But it only worked halfway as i made a post Enable tuareg mode in the emacs shell

I have completely reinstalled my os for giving a new try but without results…
