New with emacs. I'm not able to implement auto-completion for Gtk+3. I'm using CEDET and Auto Complete Mode as UI. Semantic is unable to find include files ( ), but it can parse the tags of the code in the open buffers.

Any suggestions? Thanks.
Your setup looks OK to me; I wonder if the extra "gtk/" and "gdk/" in your add-system-includes might be the problem. I just got this working with gtk-3.0 using:
(semantic-add-system-include "/usr/include/gtk-3.0" 'c-mode)
Then in your source file,
#include <gtk/gtk.h>
Followed by:
gtk_[C-c ?]
spends a minute or so processing all the header files, but it does return the completion menu as expected.
If this doesn't work for you, I notice you might be using an older version of CEDET. I use the latest dev version from the bazaar repository; I highly recommend you do the same.

I am trying to install the clang-format automatic format tool, I have installed clang-format with M-x package-install clang-format

My ~/.emacs is:

which is unsafe because it allows man-in-the-middle attacks.

But clang-format does not appear at the bottom of emacs window while Irony, FlyC, ElDoc and Abbrev appear.
Could anyone help me? Thank you!
From clang-format github instructions:
(require 'clang-format)
(global-set-key (kbd "C-c i") 'clang-format-region)
(global-set-key (kbd "C-c u") 'clang-format-buffer)
(setq clang-format-style-option "llvm")
It won't appear in the status line as it's not a minor mode.
You have to set key bindings to the function you want to use, like in the given example.
I am trying to set up the emacs to have auto-Indentation for clojure code.
Until now unsuccessful. What is the command to set into the config file for that?
Here is a sample emacs config for what i consider the "minimal" usable emacs config for Clojure. I say minimal in that I'm not willing to work without good code completion, jump to definition, project aware file handling etc:
from this example which you can clone to ~/.emacs.d:
This is just a hilight, see the init file in the example project for the context, look at the project for recent versions, etc. don't just copy these:
(use-package clojure-mode
:ensure t
:config
(add-hook 'clojure-mode-hook 'yas-minor-mode))
(use-package cider
:ensure t
:config (progn (add-hook 'clojure-mode-hook 'cider-mode)
(add-hook 'clojure-mode-hook 'cider-turn-on-eldoc-mode)
(add-hook 'cider-repl-mode-hook 'subword-mode)
(setq cider-annotate-completion-candidates t
cider-prompt-for-symbol nil)))
;; clojure refactor library
;; https://github.com/clojure-emacs/clj-refactor.el
(use-package clj-refactor
:ensure t
:config (progn (setq cljr-suppress-middleware-warnings t)
(add-hook 'clojure-mode-hook (lambda ()
(clj-refactor-mode 1)
(cljr-add-keybindings-with-prefix "C-c C-m")))))
there is also some code to add to ~/.lein/profiles.clj:
{:user {:plugins [[cider/cider-nrepl "0.10.0-SNAPSHOT"]
[refactor-nrepl "1.1.0"]]
:dependencies [[acyclic/squiggly-clojure "0.1.3-SNAPSHOT"]]}}
I added
(global-set-key (kbd "RET") 'newline-and-indent)
to the init file and this worked. I am not sure if this was the best solutaion, but it did the trick.
According to this:
The built-in completion logic in CIDER relies on the library clojure-complete, so you'll have to have it your classpath for completion to work. If you're connecting to an nREPL server started from lein (e.g. you invoked M-x cider-jack-in) - there's nothing for you to do.
So -- I'm using an nREPL jack in with Emacs 24.3, so I would guess that there is "nothing for me to do." However, I am not getting any autocompletion in my Clojure source files.
I uninstalled and reinstalled Cider via Elpa to be safe. Apparently it is not necessary to manually install any other autocompletion packages from what I've read, but I must admit that getting autocompletion to work seems to be quite a task, can anyone point out what I'm missing?
Here's my old config. I haven't been using Clojure for a while, but
I've checked that it still works:
(require 'ac-nrepl)
(defun clojure-auto-complete ()
(interactive)
(let ((ac-sources
`(ac-source-nrepl-ns
ac-source-nrepl-vars
ac-source-nrepl-ns-classes
ac-source-nrepl-all-classes
ac-source-nrepl-java-methods
ac-source-nrepl-static-methods
,#ac-sources)))
(auto-complete)))
(defun my-clojure-hook ()
(auto-complete-mode 1)
(define-key clojure-mode-map
(kbd "β") 'clojure-auto-complete))
(add-hook 'clojure-mode-hook 'my-clojure-hook)
I'm pretty sure that I went for the separate function instead of modifying
ac-sources for performance reasons (I have ac-delay at 0.4).
Confirmation:
abo-abo answer of Apr 23 at 6:57 works.
Just change "ac-nrepl" into "ac-cider" of course.

I do not want to use auto-completion for repl and script so I commented them.
You may not need them all but they are all useful. If you do not want to change the init.el file, you would better go with all packages listed.
Once you're done, make a project with Lein, then add
:plugins [[cider/cider-nrepl "0.8.2"]]
to project.clj file.
Now, it is almost done.
Open a sourcefile with Emacs, then run
M-x cider-jack-in
Then you must be able to use auto-completion feature for code!
I'm brand-new to both Emacs and Clojure and would like to set up hinting and syntax highlighting somehow similar to the video here. I have installed:
Emacs 24.x
Leiningen 2.x
Marmalade
...Then within Emacs and via Marmalade, installed the following packages:
Evil
clojure-mode
nrepl
My big-idea question is how do these major/minor modes interact and is there a "right" way to set these things up?
My smaller-idea question is how do I get the pretty syntax highlighting and code-hinting?
Thanks!
Check out Emacs Live, its a full emacs configuration created by Sam Aaron. He codes allot of Clojure so this "battery included" setup works great for Clojure coding.
https://github.com/overtone/emacs-live
Once you have cloned this and follow the instructions you are up and running with
Clojure, nrepl, git and much more.
I list my setup. Some of the stuff is redundant, since I haven't
written in Clojure for a while, but I checked and it still works.
Use clojure to start nrepl.
You might have some issue with project.clj being in the appropriate directory,
but you should figure this out.
Open a source file e.g. foo.clj.
Use C-c C-l to call nrepl-load-file
By the way, it's the canonical shortcut to load the file into inferior process.
It will work for Common Lisp, Python etc.
Use C-c C-z to switch to repl.
This again is the canonical shortcut that works for many languages.
Here's the setup code:
(require 'clojure-mode)
(defun set-syntax-parens ()
"highlight []{} etc."
(interactive)
(modify-syntax-entry ?[ "(]")
(modify-syntax-entry ?] ")[")
(modify-syntax-entry ?{ "(}")
(modify-syntax-entry ?} "){"))

here is the operative section from my favorite emacs config:

(add-hook 'nrepl-interaction-mode-hook
'nrepl-turn-on-eldoc-mode)
(add-hook 'nrepl-mode-hook 'paredit-mode)
This turns on paredit-mode everywhere, which takes a bit of getting used to though it's entirely worth it because paredit and makes using Clojure much more fun. At least once you get a handle on slurping and barfing
I use Emacs 24 from scratch with the latest yasnippet and auto-complete installed and nominally working. Now, as a emacs user and an android developer, I'd like to use my favorite editor and automate some tasks fr android development.
I know almost nothing about elisp.
My first task is to use custom snippets to add the uses-sdk tag in AndroidManifest.xml. That's ok with yasnippet but I'd like to use auto-complete to interactively propose and auto-complete android specific tags. The problem is that the major mode for AndroidManifest.xml is nxml and I don't want to propose android specifics to all nxml-mode related buffers. As a consequence, I use a condition on the buffer name in the snippet definition. Now, I'd like to add a custom hook to nxml-mode-hook but I failed to enable the auto-complete mode.
My snippet:
#contributor : Me, Myself and I
#name : <uses-sdk ... />
#condition : (string= (buffer-name) "AndroidManifest.xml")
# --
<uses-sdk android:minSdkVersion="$0" />
The .emacs part that miserably failed:
;; yasnippet

(require 'yasnippet)
(setq yas/trigger-key (kbd "C-c <kp-multiply>"))

(add-hook 'nxml-mode-hook 'ac-android-manifest-nxml-setup)
The snippet works as intended but the completion don't though the auto-completion works if I enable auto-complete using M-x auto-complete-mode.
Any help will be greatly appreciated.
