I would like to use Julia with Emacs and have installed julia-mode, julia-repl and lsp-julia. I am using Julia 1.7.3.
I have added the following to my init.el
(require 'lsp-mode)
(add-hook 'julia-mode-hook #'lsp)
(require 'lsp-ui)
(require 'julia-mode)
(require 'julia-repl)
(require 'lsp-julia)
(julia-repl-set-terminal-backend 'vterm)
(add-hook 'julia-mode-hook 'julia-repl-mode) ;; Always use minor mode
(require 'vterm)
However, when I have the (add-hook 'julia-mode-hook #'lsp) line enabled the keyboard shortcuts don't work (e.g., C-Enter is not found). All I want to do is set up julia in Emacs in a similar way using LSP with keyboard shortcuts to how I have it in VSCode.
What have I done wrong in my init.el?

I am using Aquamacs on OS X 10.9.4. I have the following lines in my Preferences.el file
(which is similar to the .emacs init file):
(add-to-list 'load-path "~/.emacs.d/")
(require 'fill-column-indicator)
(setq-default fci-mode t)
I use M-x fci-mode to manually toggle the column indicator.
How can fci-mode be enabled on startup using Aquamacs?
Don't put ~/.emacs.d itself in your load-path. Always use a sub-directory.
e.g.: use ~/.emacs.d/lisp/fill-column-indicator.el and:
(add-to-list 'load-path (expand-file-name "~/.emacs.d/lisp"))
(require 'fill-column-indicator)
This library doesn't provide a global minor mode, but you can make one yourself like so:
(define-globalized-minor-mode my-global-fci-mode fci-mode turn-on-fci-mode)
(my-global-fci-mode 1)
or toggle it interactively with M-x my-global-fci-mode RET
You should remove (setq-default fci-mode t).
fci-mode is not global, so you could use a mode hook. If, for example, your opening document on startup is emacs-lisp-mode, you could place something like this inside your Preferences.el file.
(add-hook 'emacs-lisp-mode-hook (lambda ()
(fci-mode 1)
))
You will need to use a mode hook for each major mode; or, you will need to modify fci-mode by adding a global setting.
For anyone who is interested in looking at the source-code, here is the link to the Github repository: https://github.com/alpaker/Fill-Column-Indicator
With Emacs 27 comes the display-fill-column-indicator-mode minor mode, which obsoletes the fill-column-indicator package. You can add:
(add-hook 'prog-mode-hook (lambda ()
(display-fill-column-indicator-mode)))
to ~/.emacs to enable it for prog-mode buffers, or:
(global-display-fill-column-indicator-mode)
to enable it globally. To toggle it, use M-x display-fill-column-indicator-mode.
According to the guide on the Internet, we can search in the HyperSpec for the symbol like "format" in emacs by typing C-c C-d h , However, I just cannot have it work, emacs just prompts that there's no completion for the symbol. Can somebody cope with it? thanks in advance!
Are you actually using the Slime REPL mode? Sometimes, when starting Slime without any configuration, you're not getting the REPL mode, and instead you'll be sitting in the *inferior-lisp* buffer.
First of all, check what the title of the buffer is. If it's *inferior-lisp*, it's not the correct one. It should read *slime-repl sbcl* (where sbcl refers to the CL implementation you're using).
If this is the case, then you need to make sure you enable slime-fancy in your Emacs init file. This is what I have:
(defun init-slime-configuration ()
(slime-setup '(slime-fancy slime-fuzzy))
(setq slime-load-failed-fasl 'never)
(define-key slime-repl-mode-map (kbd "C-<tab>") 'slime-fuzzy-complete-symbol)
(define-key slime-mode-map (kbd "C-<tab>") 'slime-fuzzy-complete-symbol))
(add-hook 'slime-load-hook 'init-slime-configuration)
This also allows me to use C-TAB for fuzzy expand.
I ran into this very problem after switching from the version of SLIME installed using Quicklisp (version 2.9) to that installed from MELPA (version 20141010.1357, as a dependency of ac-slime).
Using SLIME from Quicklisp worked fine with my local copy of the HyperSpec, using the settings:
(require 'slime-autoloads)
(add-to-list 'slime-contribs 'slime-fancy)
(setq slime-lisp-implementations
'((ccl ("ccl"))
(clisp ("clisp"))
(cmucl ("cmucl"))
(ecl ("ecl"))
(sbcl ("sbcl"))))
(setq slime-default-lisp 'sbcl)
(setq common-lisp-hyperspec-root "file:/usr/share/doc/HyperSpec/")
(setq common-lisp-hyperspec-symbol-table "file:/usr/share/doc/HyperSpec/Data/Map_Sym.txt")
I then completely removed and reinstalled Quicklisp (without reinstalling SLIME!), then installed ac-slime from MELPA using the Emacs package manager.
By chance I happened to notice that when I tried to lookup documentation in the HyperSpec, Emacs opened a hidden buffer with an empty file named "Map_Sym.txt" in it.
Looking at the full pathname of this file using C-h v buffer-file-name [RET] revealed that it was set to "/home/miki/file:/usr/share/doc/HyperSpec/Data/Map_Sym.txt".
As an experiment, I tried removing the "file:/" from the last two lines of my settings, to make them read:
(setq common-lisp-hyperspec-root "/usr/share/doc/HyperSpec/")
(setq common-lisp-hyperspec-symbol-table "/usr/share/doc/HyperSpec/Data/Map_Sym.txt")
It appears to have resolved the issue. Why this works, I don't know (it differs from the documentation). A bug or undocumented change, maybe?
When I start aquamacs with the autocompletion program
installed, http://cx4a.org/software/auto-complete/, with a lisp file that has el as an extension (example.el)
Then all lisp features are loaded into aquamacs including autocompletion.
But when I load a common lisp file (example.lisp) no autocompletion features are loaded.
So my question is, is it possible
to change the autocompletion code so also common lisp files are
recognized?
Thanks
From autocomplete manual:
Enable auto-complete-mode automatically for specific modes
auto-complete-mode won't be enabled automatically for modes that are
not in ac-modes. So you need to set if necessary:
(add-to-list 'ac-modes 'brandnew-mode)
Or in your case
(add-to-list 'ac-modes 'lisp-mode)
Just for info. By default the following modes are included
(defcustom ac-modes
'(emacs-lisp-mode
lisp-interaction-mode
c-mode cc-mode c++-mode
java-mode clojure-mode scala-mode
scheme-mode
ocaml-mode tuareg-mode
perl-mode cperl-mode python-mode ruby-mode
ecmascript-mode javascript-mode js-mode js2-mode php-mode css-mode
makefile-mode sh-mode fortran-mode f90-mode ada-mode
xml-mode sgml-mode)
"Major modes `auto-complete-mode' can run on."
:type '(repeat symbol)
:group 'auto-complete)
I am setting up a new .emacs environment. But with my last setup, the yasnippet menu showed the keybinding. But now it doesn't. It seems very strange. I believe I have the latest version of yasnippet. If I try expanding via a keybinding I already now (like do a "def TAB" in a python buffer) really shows that the keybinding works. But it isn't shown.
This is what I've added to my .emacs file:
; Add Yasnippets
(add-to-list 'load-path
"~/.emacs.d/plugins/yasnippet")
(require 'yasnippet)
(yas/global-mode 1)
And a screenshot:
I am not sure, I have this one also in my .emacs
(yas/initialize)
I use Aquamacs, and Aquamacs is pre-equipped with SLIME.
(setq inferior-lisp-program "/usr/local/bin/sbcl") #####!!!
(add-to-list 'load-path "/Library/Application Support/Aquamacs Emacs/SLIME/contrib")
(add-to-list 'load-path "/Library/Application Support/Aquamacs Emacs/SLIME")
(require 'slime)
(slime-setup)
As is asked in somewhere, I try to use Clojure by adding this code.
(add-to-list 'load-path "~/clojure/clojure-mode")
(setq inferior-lisp-program "/Users/smcho/bin/clj") ################
(require 'clojure-mode)
(setq auto-mode-alist
(cons '("\\.clj$ . clojure-mode")
auto-mode-alist))
(add-hook 'clojure-mode-hook
'(lambda ()
(define-key clojure-mode-map "\C-c\C-e" 'lisp-eval-last-sexp)))
)
I couldn't make it Clojure run with SLIME, but I'm satisfied with the current setting, the only problem is that because of the (setq inferior-lisp-program ...) code, I have to change the .emacs code depending on I use Clojure or SBCL.
Is there any way to solve this problem? Can I choose between multiple (inferior) Lisps?

I could make Clojure run on Aquamacs. Please refer to Running Clojure with 'lein swank' on Aquamacs problem. Forget about the settings written above, if you want to run Aquamacs/Clojure. You need just one line, (slime-setup '(slime-repl)) and lein swank.
Sure, you can use C-u M-x slime instead of just M-x slime to have SLIME ask you for the name of the Lisp executable to be launched, with whatever is your default already filled in.
There's also a slime-lisp-implementations variable which I have configured like so:
(setq slime-lisp-implementations
`((clojure ,(swank-clojure-cmd) :init swank-clojure-init)
(sbcl ("sbcl") :coding-system utf-8-unix)))
I have to say that I just can't remember what this does for me anymore (if indeed it does anything)... Type C-h v slime-lisp-implementations to learn roughly what it's supposed to do. I seem to have to type sbcl if I want to start that, which is fine by me due to the high Clojure-to-SBCL ratio in my SLIME'ing.
Update:
I have just rediscovered M-- M-x slime (that first key is meta-minus for a negative argument), which prompts for one of the names of Lisp implementations in slime-lisp-implementations (with tab completion) and then starts the required Lisp. With the above example config, M-- M-x slime sbcl starts SBCL.
(I find this useful mostly because of how it allows one to configure more complex commands to start Lisp -- e.g. (sbcl-options ("sbcl" "--an-option" "--another-option") ...), (sbcl-clbuild ("/path/to/clbuild" "lisp") ...) -- and refer to them by name.)
