Code for automatic loading of latex-preview-pane

[doctorate]

this code worked when written in the .emacs file:

(add-hook 'LaTeX-mode-hook 'latex-preview-pane-mode)

[jsinglet]

The correct code is actually as documented on the wiki. It is what I use personally. What you have done will work, but it's not optimal. Is it possible that you have a problem elsewhere in your .emacs file?

If you can send me your .emacs file I can have a look and see what might be the issue.

Are you placing that code in your .emacs file? Or in default.el?

[doctorate]

In the default.el file, I play only with default.el file. That's what I usually mean when I refer to .emacs file? I don't have .emacs file but .emacs.d folder, I guess. I have another emerging issue of PDF preview - pls see update of : http://tex.stackexchange.com/questions/190882/what-is-the-best-side-by-side-preview-method-for-emacs24-auctex

[jsinglet]

The .emacs file isn't the same as the default.el file.

Take a look at this: https://www.gnu.org/software/emacs/manual/html_node/emacs/Init-File.html

That code needs to be in your .emacs file, which should be located in your home directory (which depends on how you installed emacs, but generally not IN your .emacs.d but in the same directory as it).

In emacs, edit a new file C-x C-f ~/.emacs and place the following in it:

(require 'package) (add-to-list 'package-archives '("melpa" . "http://melpa.milkbox.net/packages/") t)

(latex-preview-pane-enable)

Then remove the latex-preview-pane code from your default.el (including that hook you wrote). I'd be interested to know if this fixes your problem.

[doctorate]

Side question: how do I know whether this piece of code should go to .emacs file or to the default.el file? I added some code like theme, fonts and many others to the default.el only - or they can go both way? In the meantime, I will do what you suggested and come back to you later

[doctorate]

Ok. I created init.el file in the home directory ~/.emacs.d/ and wrote what you suggested above, deleted the hook in the default.el and It threw the same error that I already encountered first time I tried to follow the wike code:

Warning (initialization): An error occurred while loading `c:/GNU Emacs 24.3/.emacs.d/init.el':

Symbol's function definition is void: latex-preview-pane-enable

To ensure normal operation, you should investigate and remove the
cause of the error in your initialization file.  Start Emacs with
the `--debug-init' option to view a complete error backtrace.

Hi Doctorate,

Thanks for the feedback, however that's not what I was asking you to do. Before moving forward I would suggest that you take a bit to familiarize yourself with the various emacs configuration files, their location and purpose. I'd love to write it out for you all here, but there are so many other web pages that do a better job than I could.

A good rule of thumb is really that you should do all your customization in .emacs -- I personally never use init.el, defaults.el or others. There are cases where it makes sense, however I have yet to encounter them.

To be clear, what I was asking you to do was to place that code in your .emacs file. It's a file literally named ".emacs" in your home directory. If you take a look at the link I sent you and do some more reading it will start to make sense, I promise!

Best, JLS

[doctorate]

Ok I will create .emacs, but that would be very strange as both init.el and .emacs should be equivalent according to the link you sent, quote:

filenames ~/.emacs, ~/.emacs.el, or ~/.emacs.d/init.el;

Nevertheless, I created the .emacs file in the home dir and added the code. made sure no other code in other files. restart. now without the error message, but also without latex-preview-pane in the menu. So it did not load automatically.

@doctorate, I think you have to run

(package-initialize)

to get packages to autoload.
