I have two files one .pl .lisp
I have written them using the emacs editor inside SWi and Lispwork, while I was coding I have set auto-fill-mode and used the editor in the default mode.
I would like to reindent all the code in emacs "style", is there a way to indent again all the code, be sure that all code is (under 80 columns auto-fill-mode), and make the code on less line as possible?
I have tried select-all + alt-x + indent-region or ctrl+alt+
But it seems that some line of code are indented in a strange way, is there a way to be sure thet the code is indented in the proper way?

I have a file open called test.scss, and when I press RET on a line, emacs will add 2 spaces to the current line and 4 extra spaces to the next line.
I've highlighted what the file looks like with whitespace-mode.
before pressing RET
after pressing RET
You can see that the .my-element row was auto-indented by 2 spaces, and the new line is indented by 4 spaces too many.
I want the output to look like this instead
desired output
What can I do to make emacs produce my desired output?
Here is the output of describe-mode:
Enabled minor modes: Auto-Composition Auto-Compression Auto-Encryption
Electric-Indent File-Name-Shadow Font-Lock Global-Eldoc
Global-Font-Lock Line-Number Menu-Bar Tooltip Whitespace
(Information about these minor modes follows the major mode info.)
SCSS mode defined in `css-mode.el':
Major mode to edit "Sassy CSS" files.
In addition to any hooks its parent mode `css-mode' might have run,
this mode runs the hook `scss-mode-hook', as the final step
during initialization.
Although in this case I'm in scss-mode, I see similar behavior with most of the other modes I use, such as ruby-mode, sgml-mode, js.el mode and others. I'd like to make the behavior match the desired output shown above.
Each mode can handle indentation in its own way, and you may have to look for mode-specific settings to get two-space indentation working everywhere.
For starters, you can set css-indent-offset, which should cover css-mode and scss-mode:
(setq css-indent-offset 2)
You can set the basic indenting of many other modes similarly. ruby-mode seems to use ruby-indent-level, sgml-mode uses sgml-basic-offset, and js-mode uses js-indent-level.
I've been working on this source file for a while, and indenting it just fine, and now suddenly I cannot indent lines by any means (tab, M-x indent-region, etc). Restarting Emacs doesn't fix it, closing and reopening the file doesn't fix it, and the problem seems to be isolated to this particular file.
It's a cpp file if that matters. Yes, I am working in C++ mode. Yes, syntactic indentation is on.
Look at the last part of the file that you edited. Most likely Emacs is in fact indenting, but your source code is such that indenting at the position where you are trying to indent has no effect.
IOW, look at code that precedes the position where you are trying to indent. Look for syntax problems that might be making that position actually appear to be top-level. My guess is that a syntax problem is throwing off the indenting.
You can also narrow the buffer, using C-x n n, to particular parts of the buffer, to see just where indenting does what you expect and where it does not. That will help you find any syntax problems that might be interfering.
Emacs was working fine, a few days ago some basic functions stopped working.
Alt+Ctrl+>, Alt+Ctrl+>
go to start/end buffer used to work but now I get an undefined error.
Alt+g+g goto line. It was worked, now I get an undefined error
I can't paste into the mini buffer on search with Alt+y, instead it paste the character that my cursor is on.
No one touched my .emacs file.
What is going on? I used emacs for along time and never had a problem with basic functions or pasting to the mini buffer.
Update:
Latest update on my problem is that everything is working when I use the Esc key instead of the Alt key. I don't know why or how it changes but it has nothing to do with my .emacs file or CapsLock or key pressing mistakes. Has anybody a clue why it changes and how to change it back?
Some things to check:
Is your .emacs file loading at all? Are any of the settings in your .emacs file taking effect? Alternately, try running emacs --load /path/to/your/.emacs. This will load the lisp code in your emacs file. If your settings get loaded now, then you need to move your .emacs into the right location so Emacs can pick it up.
Is another mode unbinding your keys? To check this, go to (for example) your *scratch* buffer, which should be in lisp-interaction-mode, and try a shortcut.
Is your .emacs file broken somehow? Try opening it, and commenting everything out but one binding. Then restart emacs and see what happens. If it works, keep uncommenting out sections (binary search is the way to go) to see what line breaks loading.
Are you sure you're pressing the right keys? Hit C-h c M-g g to run describe-key-briefly to see what keys you're pressing, and what they're currently bound to.
Is something wrong with the lisp code to bind the keys? I know this isn't likely, since it used to work, but try it anyway. Open up your .emacs and go to the line binding M-g g. Put your cursor after the closing parenthesis, then press C-x C-e to evaluate the s-expression containing the binding. Then, try the keyboard shortcut again. If it works, then something isn't loading your .emacs file correctly.
You can open your dot emacs and Alt-x eval-buffer. See if your dot emacs file works, or if there are any bugs.
I'm a beginner with emacs. Altough I'm finding it amusing and challenging, I still don't know some basic things, like, when I open a text or a piece of script wrote in another editors, emacs don't show the text formatted properly (missing all tabs, all text left-aligned) and vice-versa.
Also, when I copy a link with emacs with M-w, my clipboard is still empty and I can't paste it in a browser. I already did my "homework". I've read the tutorial and I'm almost finishing the manual and didn't see anything to address that.
tnx in advance.
Some editors, like Intellij IDEA for example, will indent code based on how they understand it and not based on how it was actually indented, there's no Emacs mode that operates in the same way, not to my best knowledge. If you were using something like Eclipse or MS Visual Studio before - then you probably just have a different size of tab character (this is why some programmers insist on indenting code with spaces rather than tabs). But the width of the tab character is adjustable. In order to customize it you would:
add in your initialization file (usually .emacs file in your $HOME directory, you can create one, if it is not there yet):
;; makes tab character as wide as four space characters
(setq default-tab-width 4)
though some other major editing modes override this variable, you would need to tell what language you are dealing with to get better instructions.
Clipboard, see this answer: How to copy text from Emacs to another application on Linux if you are on Linux, then likely you need to set x-select-enable-clipboard to t.
Aligning text to the right (or left for LTR languages) is not possible in Emacs, as far as I understand. You could align block of text, if you split it into lines and align on the line ends, but that would mean aligning by adding spaces at the beginning - something you don't really want to do.
Tabs should work (you might need to fix the width). Use mouse to select to the clipboard, or use CtrlInsert to copy and ShiftDelete to cut.
Assuming emacs has picked the right mode for the file - it usually does - you can press C-x h to select all, then TAB to indent all selected lines. What other editors are you using, and what platform(s)?
As for the clipboard issue, some builds of emacs work correctly with the native clipboard, some don't. You might want to investigate CUA mode.
Everytime I insert a snippet (with yasnippet) in a .tex document, I obtain a newline after the snippet. This is quite annoying for small snippets that are typically used in text style. How can I avoid that?
I read a bit about the problem (http://code.google.com/p/yasnippet/issues/detail?id=115 or http://yasnippet.googlecode.com/svn/trunk/doc/faq.html) but couldn't find a solution. Reproduce it as follows (I work with Aquamacs 2.3a on Mac OS X 10.6.8 with yasnippet version 0.6.1c):
Define ~/Library/Preferences/Aquamacs Emacs/Preferences.el to be:
(require 'yasnippet)
(yas/initialize)
(yas/load-directory "~/Library/Preferences/Aquamacs Emacs/plugins/yasnippet-0.6.1c/snippets")
define the following snippet (call it "bm.yasnippet" [bm = boldmath]; the star * symbolizes where the cursor ends -- note that there is no newline after the snippet)
# name: \bm{}{}
# key: bm
# --
\bm{$1}*
restart Aquamacs and open a .tex file and type in bm + Tab [this should insert the snippet]
A newline is added after the snippet. This is quite inconvenient since \bm{foo} is typically used in text style, so for example in "The vector \bm{x} is not the null vector". A typical cause of this is that the snippet ends with a newline which is then inserted, too. However, I specifically obtain this behavior even the snippet does not end with a newline.
I can't repro it with plain Emacs. In fact, I had this exact issue, but my problem is I had require-final-newline set to t. So Emacs was adding a newline at the end of my template.
My setup is a little more complicated but the solution for you is probably to set mode-require-final-newline to nil and restart Emacs.
To verify this is the problem, open up the template and check for the final newline.
Thanks to the answers in Temporarly disable adding of newlines in Emacs, I'm using a function to only temporarily disable the adding of final newlines in the current buffer:
(defun disable-final-newline ()
(interactive)
(set (make-local-variable 'require-final-newline) nil))
the reason why u got a new line is that your snippet has space or tab at the end.
Ctrl+e and Ctrl+k to kill them will make it works, nearly 1 hour to figure it out...
I had a similar issue with a few snippets, one of that was \frac{}{} which I use quite often.
The snippet version of frac that I use is not the one bundled with yasnippets.
The issue was that I edited some of the snippets in VIM and when you save the file, VIM automatically appends a newline to it.
To resolve it I had to remove the newline in a different editor e.g. emacs.
