snippet of my init.el
;; start auto-complete (melpa) with emacs
(require 'auto-complete)

So when I write code on Emacs lisp, it's show context help "on fly". OK.
Here example:
Also I write code on Android. I use IDE Eclipse that also show context help "on fly". Here example:
It's possible in Emacs to show context help when I write code on Anroid?
There is Eclim. Its not specific to Android development, but makes Eclipse features available for Emacs. I used it in conjunction with Company for code completion.

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?
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?
I installed auto-complete using the marmalade repo. Everything installed correctly and after moving stuff around I managed to start up and run auto-correct without any errors with the following code in my init.el:
;; auto-complete
(add-to-list 'load-path "~/.emacs.d/elpa/auto-complete")
(require 'auto-complete-config)
(add-to-list 'ac-dictionary-directories "~/.emacs.d/elpa/auto-complete/dict")
(ac-config-default)
Now I can use auto-complete with no hick-ups with Emacs Lisp but whenever I use any other mode, like, Java, C, or C++ it doesn't work at all.
I have yasnippet installed too (it works perfectly), not sure if that might have anything to do with it. Here's the relevant code in my init.el:
;;yasnippet
(add-to-list 'load-path
"~/.emacs.d/plugins/yasnippet")
(require 'yasnippet)
(yas-global-mode 1)
I am in the process of learning Emacs and currently I'm still a noob. I've been looking all over the documentation and SO but haven't found anything. I'd really appreciate any help whatsoever on this.
You may need to add completion sources. Here's what's in my config:
(set-default 'ac-sources
'(ac-source-abbrev
ac-source-dictionary
ac-source-yasnippet
ac-source-words-in-buffer
ac-source-words-in-same-mode-buffers
ac-source-semantic))
Update: ac-config-default should cover this, but if autocomplete isn't activating for those modes, try putting the following in your init.el:
(dolist (m '(c-mode c++-mode java-mode))
(add-to-list 'ac-modes m))
(global-auto-complete-mode t)
Update2: I've posted a gist that adapts your init.el to pull autocomplete using package-install.
I can't tell what version of auto-complete you were referencing, but the latest is working fine for me.
I have exact same issue as you. Emacs-Lisp works perfect with auto-complete but C, C++ doesn't work. After trying with various combination, I find out that commenting out yasnippet from .emacs solve my issue. Hope this could help you. My auto-complete version is 1.3.1.
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've tried to migrate to Emacs several times for Clojure development, following a variety of blogposts, screencast and tutorials, but somewhere along the way something always went wrong - keybindings that didn't work, incompatible versions, etc, and I found myself scrambling back to Vim. But I know I want Paredit and SLIME.
So, I'm going to try again, this time backed by the powerful Stack Overflow™ community.
I hope that the answer to this question will remain up-to-date, and can serve as a reference for tentative converts like me.
What I'd like is:
The latest stable release of Clojure
Aquamacs (if it's good enough for Rich Hickey, it's good enough for me), a recent version
Clojure Mode
SLIME/SWANK
Paredit
Anything else that's indispensible?
Step-by-step instructions to install the above would be excellent - preferably in shell script format. I'd also like some hints on how to get started with the most common Clojure-related actions (including key-bindings), including links to documentation and cheatsheets.
These are the steps I took to set them up without using ELPA. Hope this helps.
Get SLIME using MacPorts
sudo port -v install slime
Get paredit
curl -O http://mumble.net/~campbell/emacs/paredit.el
Get clojure & clojure-contrib
Either using MacPorts
sudo port -v install clojure clojure-contrib
Or downloading directly
curl -O http://build.clojure.org/snapshots/org/clojure/clojure/1.1.0-master-SNAPSHOT/clojure-1.1.0-master-20091202.150145-1.jar
curl -O http://build.clojure.org/snapshots/org/clojure/clojure-contrib/1.1.0-master-SNAPSHOT/clojure-contrib-1.1.0-master-20091212.205045-1.jar
Get clojure-mode and swank-clojure (Emacs side)
git clone http://github.com/technomancy/clojure-mode.git
git clone http://github.com/technomancy/swank-clojure.git
Get swank-clojure (Clojure side)
Either downloading pre-built jar file
curl -O http://repo.technomancy.us/swank-clojure-1.1.0.jar
Or building from source (assuming lein is installed)
cd path/to/dir/swank-clojure
lein jar
Put clojure, clojure-contrib and swank-clojure .jar files in ~/.swank-clojure or ~/.clojure (the default places where swank-clojure.el searches for them).
Add to either ~/.emacs or ~/Library/Preferences/Aquamacs Emacs/customization.el (change paths to match your own settings)
(add-to-list 'load-path "/opt/local/share/emacs/site-lisp/slime/")
(add-to-list 'load-path "/opt/local/share/emacs/site-lisp/slime/contrib/")
;; Change these paths to match your settings

Download and install Aquamacs.
Download and install ELPA (http://tromey.com/elpa/install.html)
Do M-x package-list-packages
Mark the lines called "clojure-mode" and "swank-clojure" with "I" then press "X".
Done.
Here's a blog post that mentions Aquamacs: Setting up Clojure, Incanter, Emacs, Slime, Swank, and Paredit
There seems to be a fairly easy way to set up Aquamacs 2.4 and SLIME for clojure:
Install Clojure
Install Aquamacs 2.4 from here "http://aquamacs.org/"
Install the Aquamacs SLIME package from here "http://aquamacs.org/download.shtml"
This will not work so...
Get the latest version of SLIME from here "http://common-lisp.net/project/slime/#downloading" - you want the CVS snapshot tar file
Unpack the SLIME tar file and copy it into
/Library/Application Support/Aquamacs Emacs/SLIME
Seems to work OK for me...
I know the OP wants to use Emacs for Clojure dev. I'm an emacs fan myself, but I found using Enclojure (http://www.enclojure.org/home) to be a great way to get started quickly with hacking Clojure.
Today I would head for https://github.com/tehcurtis/aquamacs-emacs-starter-kit/network
this is for ruby and wont work at first but anyway. git clone and copy things to Preferences.el according to readme. Fix the brokenness by edit the ~/Library/Preferences/Aquamacs Emacs/ and comment out almost everything in modes.el (I have only (setq-default indent-tabs-mode nil) left in the file)
The good part: you have installed elpa-package-manager with less hassle
now: use
M-x package-list-packages
go to
clojure-mode (press I)
slime (press I)
slime-repl (press I)
Press X to install
done.
Caveat: clojure-jack-in wont work so you have to
M-x slime-connect
and press enter twice and y to start.
