It would be fantastic if it could C-c ` automatically if there were any errors aswell. (` is a bit of a hassle of danish keyboards)

I might not be understanding your question quite right, but I make pretty heavy use of 'shell-command for something like this. I have a little function called "command-runner" that does this:

code:

(defun command-runner ()
  (interactive)
  (save-buffer)
  (shell-command my-current-command))

I can set the variable "my-current-command" to something like "cd project_folder; latex myfile; open myfile.pdf;" and then when I hit the keybinding for this function (C-\ in my case) it saves the file, compiles it, and opens it. And I get compile errors in the mini-window at the bottom of the screen.

Everything you asked about is customizable in the compile command. The customization variables affect the whole session, so I don't recommend setting them permanently in .emacs. However you can define commands to toggle them as needed.

Lisp code:

(defun enable-quick-compile ()
  (interactive)
  (setq compilation-ask-about-save nil)
  (setq compilation-read-command nil)
  (setq compilation-auto-jump-to-first-error t))

(defun disable-quick-compile ()
  (interactive)
  (setq compilation-ask-about-save t)
  (setq compilation-read-command t)
  (setq compilation-auto-jump-to-first-error nil))

You will have to run the compile command once the hard way, to get a prompt for a command line.

You can also set them as file local variables, if you're mainly running compile from one file.

There is most likely a better way to do this, but here's what I do:

code:

(defun set-current-command (new-com)
  (interactive "sSet command: ")
  (setq current-command new-com)
  (message (concat "Set command to " current-command)))

(defcustom current-command
  "echo \"You have to set this.\""
  "the command you want to run")

I give myself the 'set-current-command function, and I defcustom the current-command variable with a default so if I try to run it before I've set it, nothing harmful happens.

Like I said, this may not be the best way of accomplishing this goal, but I use it all the time and it works well for me

edit to add: I stole this idea from Gary Bernhardt's Destroy All Software screencasts. He uses Vim, but the technique is pretty similar to this. BTW, if you are a programmer you should totally check out his videos.

fishbacon: Nov 4, 2009; wonderful yet strange smell

I just discovered how powerful YAsnippets can be, I was having to do a lot of repetitive work for Uni (we have a bunch of small hand-ins this semester) and I decided to look into templates, turns out YAsnippets just does cool stuff with fields and elisp code.

I spend like 2 hours today figuring out how to do something, and I ended up actually learning a few things about elisp. I love when a simple challenge ends up brightening my whole day.

Sharing of my *Scratch* hiding technique:

Lisp code:

;; bury *scratch* buffer instead of killing it
(defadvice kill-buffer (around kill-buffer-around-advice activate)
  (let ((buffer-to-kill (ad-get-arg 0)))
    (if (equal buffer-to-kill "*scratch*")
        (bury-buffer)
      ad-do-it)))

It simply moves scratch to the back of the queue whenever I try to kill it, because it is such a great buffer to keep around.

I also fiddled with kbd today, turns out it will return exactly what "C-�" means so that I don't have to have anything ugly in my emacs file.

Iv just installed Emacs on a windows machine and I'm having trouble compiling C++ programs. As far as I can tell it is something to do with the compiler (make-k, I understand this is for Linux) what I'm struggling with is how to change the compiler that Emacs is using.

In short does anyone know how to change the compiler Emacs uses for C++?

Putting (setq compile-command "something or other") in your config changes the default command line, for all languages. It can be customized for particular language modes, and the documentation of the compile-command variable describes how, but this requires detailed elisp coding. In your case you would customize c++-mode-hook instead of c-mode-hook.

I wrote the auto-complete backend for ropemacs. I don't know the status of it today (some dude on GitHub was going to try to upstream it, but I lost track of that).

auto-complete is fairly complicated and tends to be slow. I'd recommend against using it unless you tweak it properly. It's probably possible to write a CEDET backend for it, but it'd require some elisp knowledge.

I've used Vim exclusively for the last couple of years, but I just recently switched to emacs after reading about some of the advanced features and modes available.

I use evil all the time, it works perfectly and is well maintained, though you need a couple of other config changes to make it totally feel like vi. I mapped Esc to totally kill any command anywhere, so it's now pretty much identical to Vim when I'm not using one of the fancy modes. All the vim commands I commonly used are emulated with the exact same syntax.

As I use it, it looks like Vim, but with better file and directory management, more features (the regex replace in evil visually shows you the changes as you type the command), and better written extension scripts.

I'm glad I'm not the only one who doesn't care for nxHtml. I have some mental block when trying to use that drat thing. For just multiple mode support without alot of the extra cruft check out MultiWebMode (https://github.com/fgallina/multi-web-mode) Basically to use it you just setup a plist where the label is the name of the mode you want to use and the value is a regex telling it how to recognize the region for that mode. This is all documented. As a plus you can use whatever major-mode you want for each thing easily. Want js2-mode for javascript? Go for it. Want some funky custom mode for css? Sure, why not. Etc.

This is from a hell of a while back, but do you actually use js2-mode with multi-web-mode? Could you let me know where you installed both from and what your configuration looks like? The latest version of js2-mode I have is from 2013, and it still has a comment to the effect of "this does not yet work with multi-mode modes", and when using it I just get a bunch of red-highlighted code and the error 'Unexpected end of file'.

The latter is a file that emacs uses to track files that have been auto-saved successfully so they can be recovered following a crash. The former is, I'm guessing, the directory where emacs has been set up to place the actual auto-saved files on your system.

So the other day I upgraded to emacs24 - had to build from source because aptitude is stuck on 23. And yesterday I was doing some TeX editing and realized I didn't have AUCTeX. "Gee", I thought, "maybe I should use this package manager thing that I basically specifically installed emacs24 for." So I did. And then AUCTeX wouldn't work still. And I couldn't find a reason until, while reading the doc, I realized that the "base" .el file, the one you have to load to make it all work, is named texsite.el for some reason. Lo and behold, if you change texsite.el to be auctex.el, the same as the package name, poo poo Just Works.

Am I wrong about that? Did I accidentally fix it some other way? Because if I'm not, why the gently caress don't the auctex folks just name their goddamn file auctex.el so it doesn't break ELPA?

I'm trying to use electric-layout-mode in C, but I can't figure out how to set it up. Here's the documentation:

Documentation:
List of rules saying where to automatically insert newlines.
Each rule has the form (CHAR . WHERE) where CHAR is the char
that was just inserted and WHERE specifies where to insert newlines
and can be: nil, `before', `after', `around', or a function of no
arguments that returns one of those symbols.

I tried:

code:

(setq electric-layout-rules '((";" . "after") ("{" . "around")))

But that gives me a syntax error when I eval the buffer. I'm not sure if setq is the wrong thing to be using or if I'm making the list wrong or what.

In terms of emacs.d customization, this is one of the best things I've ever done.

Lisp code:

(setq custom-file (concat dotfiles-dir "custom/" system-name ".el"))
(setq per-machine-config-file (concat dotfiles-dir "config/per-machine/" system-name ".el"))

(load custom-file 'noerror)
(if (file-exists-p per-machine-config-file)
    (load per-machine-config-file))

What this does is assume, in your ~/.emacs.d, a set of directories exist with Emacs Lisp files named after the actual machines you run Emacs on. So if you have machines Foo and Bar, your custom files will be ~/.emacs.d/custom/foo.el and ~/.emacs.d/custom/bar.el, respectively, and then you can run extra elisp code in ~/.emacs.d/config/per-machine/foo.el and ~/.emacs.d/config/per-machine/bar.el. This makes it super easy to keep work-related configurations out of your public repos, since you just gitignore those files.

This unfortunately does not have some kind of mechanism for customizations you want shared between computers.

You can also do this for the different operating systems you run Emacs on (i.e. OS X versus Linux), although I do that on the function level:

Lisp code:

(defun system-specific-gnu/linux ()
  (set-face-attribute 'default nil :height 120)
  (set-face-attribute 'default nil :font "Source Code Pro-12")
  (defadvice raise-frame (around wmctrl activate)

                               "_NET_ACTIVE_WINDOW" 32 '(1))
      ad-do-it)))

(defun system-specific-darwin ()
  (set-face-attribute 'default nil :height 140)
  (set-face-attribute 'default nil :font "Menlo-14")
  (global-set-key [(control meta f2)] 'ns-toggle-fullscreen)
  (require 'smooth-scroll)
  (smooth-scroll-mode)
  (setenv "WORKON_HOME" (expand-file-name "~/.virtualenvs"))

  ;; A quick & ugly PATH solution to Emacs on Mac OSX
  (setenv "PATH" (concat (expand-file-name "~/System/bin") ":" "/usr/local/bin" ":" (getenv "PATH"))))
