Running Emacs 24 (Mac OS). I enabled line-number-mode via M-x, but I'm still not seeing any line numbers? What's up? Do I need to edit my .emacs file too?
Thanks.
It sounds like you want linum-mode.

I don't want my whitespace colored like in the below screenshot.
I have the default whitespace-mode turned off.
How can I disable this highlighting?
By the name of the face highlight-indent-face, it looks like this is being caused by highlight-indentation-mode or highlight-indentation-current-column-mode, both provided by the same extension.
Check C-x m to see which one is turned on.
Now you can turn it off (more likely stop turning it on automatically in your configuration).
It looks like you've managed to turn on whitespace-mode. Turn it off with M-x whitespace-mode.
It's not turned on by default, so if it's always on when you start Emacs, check your .emacs file to see if the command shows up in there.
I'm running Emacs 24 on Ubuntu 10.04, coding c++ in the default c++ environment. Periodically after a while coding, my indentation engine seems to break -- pressing "tab" to indent places places any line at the beginning of the line. Selecting the entire buffer result in the entire buffer being un-indented. This problem effects all buffers, current or later opened. So far the only way I have found to repair it is the (highly inconvenient) step of restarting emacs. Is there another way to reboot my indentation engine? Attempting to load different indentation styles does not fix the problem.
Have you read this thread?

It sounds like you can fix your problem by updating cc-mode.
I see the same with 24.3 but I found that closing and re-opening the affected buffer also solves the issue.
This is a recurring issue on my system (Emacs 24.3 x86_64 Red Hat Linux) and could possibly be a bug introduced in Emacs 24 judging from the link posted by event_jr.
I encounter the issue fairly often and usually resolve it by reloading whatever buffer I'm working in:
M-x revert-buffer RET yes RET
This way you don't have to close neither buffer nor Emacs.
I found unbalanced preprocessor directives (#ifdef etc) can throw it into this sort of behaviour
I am running Emacs 23.3 on Windows XP. When Emacs is started, the mode line will assume one of these two appearances at random. Needless to say, I prefer the first one. How do I figure out what is going on and how do I make the first one stick?
The images don't show it, but the first one has a GUI type appearance. If I hover over the various bits of text with a mouse, e.g. Help then the text Help turns into a button with shadows etc.
The black mode line appears to be a text mode widget. The only thing that the mouse will change on it is the highlighting.
PS: Thanks JSON!
I vaguely remember this happening years ago depending on whether or not I started Emacs from Remote Desktop. Perhaps there's an issue with color depth?
See if anything has changed your settings to
(set-face-background 'modeline "#000000")
(set-face-foreground 'modeline "#FFFFFF")
(EDIT: Color codes corrected) in any of your .el files.
I've recently started learning emacs since I was unhappy with Textmate and as a starting point read the "Effective Emacs" article by Steve Yegge. I was very keen on his CTRL -> CAPS LOCK swap, but I don't want to do it OS-wide, I want this swap to only occur in emacs every time I run it.
I was wondering if there's a way to do this in the .emacs file instead of going into system-properties and swapping it for the whole OS. I'm using Mac OS X Leopard.
This is, unfortunately, not possible to do in your .emacs file.
I'm pretty old school sometimes and I like working with Emacs in my terminal. (I work with IDEs all the time. But sometimes, when in the privacy of my own home, I just like a text editor a terminal and a beer)
However, the default Emacs that comes with OS X does not seem to highlight the comments in font-lock-mode. I've seen this behavior in both Python and C mode.
I've already searched some forums and I found one post where the person was having the same problem as me:
http://forums.macosxhints.com/showthread.php?p=512361
Is is there any way to fix this problem?
I had this exact same problem. The solution is to change the color used for the comment face as follows:
(set-face-foreground 'font-lock-comment-face "red")
Or, if you only want to do this for certain modes:
;;; Only do this for the common C mode (C, C++, Objective-C)
(add-hook 'c-mode-common-hook #'(lambda () (set-face-foreground 'font-lock-comment-face "red")))
For more information on faces, see http://www.gnu.org/software/emacs/manual/html_node/emacs/Faces.html.
I'm not sure exactly how to fix it, but I'm fairly certain there's something you can put in the .emacs file. In fact, I think I've done that before. I'll look for my file and let you know what I can find.
I'll try and get you my .emacs file when I get home from work tonight.
[edit] I've looked and looked, and can't find a .emacs file on either system that I use, and on my OS X install (Leopard default), it looks like it does it correctly by default. I did some research here, and it looks like the default installations no longer use .emacs files, because there's folks like me that mess around with them and break things, and they got tired of having to help us fix it. But, there is a set of menus that will let you tweak things. Start by typing "M-x customize RET", where M is the meta character (on my OSX install, this is the esc key. Don't hold it down, just type it like a regular character. That'll get you into a menu of stuff you can change. I didn't poke around too much, so I'm not sure where in the menu you'll find what you're looking for. Sorry I couldn't be more help.
In my experience this is usually related to a unpaired quote (single-, double-, or otherwise) somewhere in an existing comment.
Hunt those occurences down and eradicate them in your source code (or if you are more ambitious, see if you can update the fontlock code in your major modes' emacs source code)
When I have encountered this in editting Perl in emacs, I often switch major modes to cperl-mode as it typically handles parsing the perl better than the default perl-mode.
