If I have code that has a lot of if/then/else conditions like so: if () { if () { } else { } } else { if () { } else { } } and there might also be a lot of text inside those conditions. How can I quickly find the outermost if as well as the corresponding else. ...
When I open a buffer in Emacs containing a German Umlaut (the word "Präsentation" occurs in a string), Emacs automatically converts it to a different encoding as soon as I save the file. How can I tell Emacs to leave the encoding alone? ...
I use emacs+auctex and auto-fill-mode. Now sometimes I want to search (and replace) a string containing spaces like "test1 test2". The problem is, that auto-fill-mode replaces space-characters sometimes by newline characters. So search and replace of "test1 test2" does not find those occurrences of this string where auto-fill replaced ...
Hi, I would really like to have the italic style disabled in Emacs. In this post it is explained how to disable bold and underline, but not italic. Does anyone know how to do that? Using tab-completion, I can see I have these available set-face-background set-face-background-pixmap set-face-font set-face-foregr...

After placing the yasnippet-0.6.1c folder in ~/.emacs.d/plugins/, I tried to eval the following in my .emacs: (add-to-list 'load-path "~/.emacs.d/plugins/yasnippet-0.6.1c") (require 'yasnippet) ;; not yasnippet-bundle (yas/initialize) (yas/load-d...
How can I make vertical splitting the default instead of horizontal splitting in Emacs? My use case: I want to compare a Python file with an older revision of itself from the svn-repository, I do this with the C-x v ~ command. Unfortunately this always opens a second buffer while splitting the window horizontally. Vertically would be m...
In Emacs, C-u C-SPC will "jump to the mark, and set the mark from position popped off the local mark ring". Is there a way to go the opposite way around the mark ring? Say you have typed C-u C-SPC several times and want to go back to a mark you have seen without going all the way around the ring. ...
In Emacs Lisp (elisp), if I want to get several values from the user, is there a better way than just asking for each value in turn in the minibuffer? Ideally, there would be a library that would let me define an input form with several fields, present that form to the user (as a text-based dialog in text mode, and as a GUI-based dialog...
I'm pretty new to Java, and I need to build up programming environments for it (editing, compiling, testing, debugging, and deploying/making jar files). And, even though I'm not a super expert of emacs, I'm a big fan of this wonderful tool. Here comes my question. Is it wise to use emacs for Java development? Is Eclipse better for Jav...
Quite often I define a ruby symbol (eg. :some_value), then I want to create a method with the same name def some_value. Unfortunately, the autocompletion(M + /) for the second occurrence of some_value string does not work, being slightly different (:some_value vs some_value). How can I setup emacs to handle such events? ...
I'm having trouble getting SBCL to start under slime. I've messed things up and I don't know how to recover. This was working fine until I... Had a problem loading a package via asdf. At which point I started debugging the asdf.lisp provided with SBCL to see what was going wrong. The sole change I made was to put a (break) in which ...
I don't at all like the default colorings on Mac OS X, but I love them on Ubuntu. What config files govern these things? I'm hoping I can just copy the relevant files from Ubuntu onto Mac OS X. ...
Is it possible to present Markdown rendered in an Emacs buffer using Emacs' own buffer text formatting capabilities? Emacs in graphical environments has rich text presentation capabilities (font styles, colors, links and even images) so it should be quite possible. Are there any existing implementations? Note that the idea is to have th...
Hello, I like the Emacs color theme clarity. I start the theme with M-x color-theme-clarity. However, I would rather have the background was always black, rather than the mixed black and white as seen in my screenshot. It seems like if there is a line that has never had text on it, it will be white rather than black. How do I fix this? ...
I'm currently doing a lot of work on remote machines with tramp. However the project logic gets confused when building make command lines as it will attempt to cd to some /ssh:blah.... path. Does tramp provide any API functions to test if a buffer or a buffer filename is actually managed by tramp and therefor on a remote machine? Can it...
