Have anyone added support for ansi-color in compilation-mode Emacs? If so what property/attribute does the color-writing program have to check for in order to make sure its active terminal supports ANSI-escape coloring.
There's already a function for applying color to comint buffers. You simply need to enable it on compilation buffers:
(require 'ansi-color)
(defun colorize-compilation-buffer ()
(toggle-read-only)
(ansi-color-apply-on-region compilation-filter-start (point))
(toggle-read-only))
(add-hook 'compilation-filter-hook 'colorize-compilation-buffer)
Color writing programs should check the TERM environment variable and the terminfo database to check if the terminal supports color. In practice, a lot of programs ignore this and rely on a user setting. Emacs will set the compilation terminal type to dumb by default but this can be overriden by setting the compilation-environment variable.
Update: Note that in Emacs 24.5 the two calls to (toggle-read-only) in the code above are not needed.
My optimized solution which don't pollute M-x grep (only for M-x compile):
(ignore-errors
(require 'ansi-color)
(defun my-colorize-compilation-buffer ()
(when (eq major-mode 'compilation-mode)
(ansi-color-apply-on-region compilation-filter-start (point-max))))
(add-hook 'compilation-filter-hook 'my-colorize-compilation-buffer))
As of emacs 28.1, this is now a built in !
(require 'ansi-color)
(add-hook 'compilation-filter-hook 'ansi-color-compilation-filter)
Or with use-package
(use-package ansi-color
:hook (compilation-filter . ansi-color-compilation-filter))
Riffing on #gavenkoa's solution:
(when (require 'ansi-color nil t)
(defun my-colorize-compilation-buffer ()
(when (eq major-mode 'compilation-mode)
(ansi-color-apply-on-region compilation-filter-start (point-max))))
(add-hook 'compilation-filter-hook 'my-colorize-compilation-buffer))
This will not block errors but will still not raise an error if ansi-color is unavailable. Personally, I find the wildcard catch semantics of ignore-error distasteful.
Riffing on #stribb's solution, which riffs on #gavenkoa's solution, this is how to set it up with the awesome use-package:
(use-package ansi-color
:config
(defun my-colorize-compilation-buffer ()
(when (eq major-mode 'compilation-mode)
(ansi-color-apply-on-region compilation-filter-start (point-max))))
:hook (compilation-filter . my-colorize-compilation-buffer))
As of 2020, the most modern way appears to be the xterm-color Emacs package.
See my answer on the duplicate question for details.

I use use-package for my emacs configuration.
Unfortunately I cannot properly configure the flycheck package to work with C++11 extension.
Here what I have so far:
;; == Flycheck ==
(use-package flycheck
:ensure t
:defer t
:init
(global-flycheck-mode)
:config
(setq flycheck-clang-language-standard "c++11"))
Although I set the proper variable, the flycheck gives me an error on c++11 syntax (e.g. auto i = 10).
What am I missing?
I think I had the same problem once. I cannot test it right now (will do it later today) but what I finally did was adding a hook to c++-mode rather than setting flycheck-clang-language-standard variable.
Here is code from my init file.
(add-hook 'c++-mode-hook
(lambda () (setq flycheck-clang-language-standard "c++11")))
You can try to use it in your use-package.
EDIT
Okay, I just checked it. When in my init.el file I have only
(require 'flycheck)
(flycheck-mode)
(setq flycheck-clang-language-standard "c++11")
flycheck highlights auto variable in a cpp file and I can see in the minibuffer following information.
rvalue references are a C++ extension
When I change my init.el file to
(require 'flycheck)
(flycheck-mode)
(add-hook 'c++-mode-hook
(lambda () (setq flycheck-clang-language-standard "c++11")))
There is no error.
Org-mode's C-cep does export as LaTeX and process to PDF. How can C-cep be executed on each C-xs?
Also, in all likelihood this probably isn't the optimal solution, so feel free to propose something better. As it is now, I have to do both C-cep and C-xs.
Final solution
A tiny modification of abo-abo's answer below that doesn't open the PDF, lets Skim pick up any change, and thus keeps the focus on Emacs.
(defun org-export-as-pdf ()
(interactive)
(save-buffer)
(org-latex-export-to-pdf))
(add-hook
'org-mode-hook
(lambda()
(define-key org-mode-map
(kbd "<f5>") 'org-export-as-pdf)))
Also, one should upgrade Org to version 8 from a fresh Emacs session: that is, no Org-command should be executed prior to installing with the package-manager. Otherwise you'll hit the Invalid function: org-with-silent-modifications bug.
You can use this:
(defun org-export-as-pdf-and-open ()
(interactive)
(save-buffer)
(org-open-file (org-latex-export-to-pdf)))
(add-hook
'org-mode-hook
(lambda()
(define-key org-mode-map
(kbd "<f5>") 'org-export-as-pdf-and-open)))
UPD
This requires org-mode 8.0.0 and up. It's easily installed with list-packages.
I have slime with sbcl working in emacs 24.1 but can not get a slime repl to open.
I can use M-x slime to make a connection to sbcl in a inferior-lisp buffer but I can not invoke the slime-repl or get a nice lisp auto-indent when editing lisp files even though I am loading the slime-fancy contrib in .emacs. I don't get any error messages during start-up.
When I try M-x slime-repl I get [No match].
my .emacs file:
(setq inferior-lisp-program "sbcl")
(add-to-list 'load-path "c:/home/bin/emacs/site-lisp/slime/")
(require 'slime)
(require 'slime-autoloads)
(slime-setup '(slime-fancy))
I used this method for the installation:
http://www.pchristensen.com/blog/articles/installing-sbcl-emacs-and-slime-on-windows-xp
I have noticed a pattern that almost everything I try with Python and Clojure works as described and almost nothing I try related to common lisp works. I have also tried cusp with eclipse. I am willing to try yet another approach if there is something more recent for common lisp in windows.
After playing with Sujoy's answer and trimming it down to get it to work, I realized my original problem was caused by the (require 'slime) statement. The following .emacs file gets the slime repl to open as expected.
(setq inferior-lisp-program "sbcl")
(require 'slime-autoloads)
(slime-setup '(slime-fancy))
Only 'slime-fancy will not setup the REPL. Try the below snippet. Put it in a buffer and eval.
Of course, you do not need to setup the hyperspec root as well, but that helps a lot :)
EDIT: missed out on the autoloads I am using, so here's the full config.
the keybinding (using minor-mode keymap, global mapping can be used just as easily)
(define-key my-keys-map (kbd "<f5>") 'slime)
the autoloads
;; slime mode
(autoload 'slime "my-slime" "Slime mode." t)
(autoload 'slime-connect "my-slime" "Slime mode." t)
Here's my-slime.el
(provide 'my-slime)
(eval-after-load "slime"
(setq slime-lisp-implementations
(slime-setup '(slime-asdf
slime-autodoc

I'm using auto-complete and yasnippet in Emacs and I am confused by their settings. I placed the following code in my .emacs:
(add-to-list 'load-path "~/.emacs.d/plugins/yasnippet")
(require 'yasnippet)
(yas/global-mode 1)
(global-set-key (kbd "C-i") 'yas/expand)
(setq yas/also-auto-indent-first-line t)
(add-to-list 'load-path "~/.emacs.d/plugins/autocomplete/")
(require 'auto-complete-config)
(add-to-list 'ac-dictionary-directories "~/.emacs.d/plugins/autocomplete/ac-dict")
(ac-config-default)
(setq ac-use-menu-map t)
(define-key ac-menu-map "\C-n" 'ac-next)
(define-key ac-menu-map "\C-p" 'ac-previous)
(defun ac-js-mode()
(setq ac-sources '(ac-source-yasnippet
ac-source-symbols
ac-source-words-in-buffer
ac-source-words-in-same-mode-buffers
ac-source-files-in-current-dir
)))
(add-hook 'js-mode-hook 'ac-js-mode)
I am trying to set yasnippet as the first candidate in the auto-complete popup menu. However, as the example below shows, this doesn't work with my current settings: when I type the word for, formatItem is in first position and for in second. formatItem is just a local function in current buffer.
for_____________
|formatItem |
|for a|
|for s|
|force s|
|foreachv s|
----------------
So my question is: how can I make yasnippet the first candidate in auto-complete? And is there something missing in my .emacs config?
Any help is appreciated.
ac-config-default installs hooks to setup sensible default ac-sources values. These hooks (especially ac-common-setup) might interfere with your settings.
You can check this by looking at the actual value of ac-sources (C-h vac-sources) in a js-mode buffer to see if it has been modified by comparison to your custom value.
If this is the case, I see two solutions:
stop using ac-config-default and specifiy all autocomplete settings,
advise the faulty hook to put ac-source-yasnippet at the beginning of ac-sources after it has run. Assuming ac-common-setup is indeed the troublemaker, this would look like:
(defadvice ac-common-setup (after give-yasnippet-highest-priority activate)
(setq ac-sources (delq 'ac-source-yasnippet ac-sources))
(add-to-list 'ac-sources 'ac-source-yasnippet))
after turning on xterm-mouse-mode, any click on the in the screen returns "mouse-1 is undefined". What should I be defining "mouse-1" as? Is there some reason my mouse clicks are returning this event, and not others its suspecting?
For Emacs in iTerm 2, I've found that the following bit in my ~/.emacs file works very well, providing the ability to insert the character at an arbitrary location, mark a region, and use the scroll wheel:
;; Enable mouse support
(unless window-system
(require 'mouse)
(xterm-mouse-mode t)
(global-set-key [mouse-4] (lambda ()
(interactive)
(scroll-down 1)))
(global-set-key [mouse-5] (lambda ()
(interactive)
(scroll-up 1)))
(defun track-mouse (e))
(setq mouse-sel-mode t)
)
I put this in my .emacs:
(require 'mouse)
(xterm-mouse-mode t)
(defun track-mouse (e))
(setq mouse-sel-mode t)
and that seems to do the trick, and now a mouse click in a split changes focus to the split.
Note: I am using iterm2, and I found the info here: http://groups.google.com/group/iterm2-discuss/browse_thread/thread/8e1f2ee7db26c07d/17ac15e69c554998?show_docid=17ac15e69c554998&pli=1
Mac OS X's Terminal.app does not support mouse reporting. However MouseTerm is a SIMBL plugin that provides it with this feature. http://bitheap.org/mouseterm/
Install MouseTerm and put the following in your Emacs config file:
; enable mouse reporting for terminal emulators
(unless window-system
(xterm-mouse-mode 1)
(global-set-key [mouse-4] (lambda ()
(interactive)
(scroll-down 1)))
(global-set-key [mouse-5] (lambda ()
(interactive)
(scroll-up 1))))
I suspect that installing the emacs-goodies-el will provide the appropriate bindings.
