My emacs is running on Window 7 and I have just installed yasnippet via M-x package-list and added few lines to my .emacs file because I read around the web that it needs to be initialized.

I tried writing a simple yasnippet for LaTeX, calling it "fraction", triggered by typing fr+ TAB and saved it in ~\.emacs.d\elpa\yasnippet-0.8.0\snippets\latex-mode. This is the code.

# -*- mode: snippet -*-
# name: fraction
# key: fr
# --
\dfrac{$1}{$0}

Since yasnippet was adding a newline everytime I triggered this snippet I modified the .emacs file. This is how it looks now:

;; yasnippet
(add-to-list 'load-path "~/.emacs.d/elpa/yasnippet-0.8.0")
(require 'yasnippet)
(setq yas-snippet-dirs '("~/.emacs.d/elpa/yasnippet-0.8.0/snippets"))
(setq-default mode-require-final-newline nil)
(yas-global-mode 1)

Now however, everytime I type 'fr' it sure gives me \dfrac{}{} but as soon as I write inside the first pair of curly braces, the same value appears in the second pair of braces (denominator) and pressing TAB pushes the cursor out of the last '}'. What am I missing here? How can I fix this problem?

My entire .emacs file is below. I'm probably doing something wrong, please help me correct it.

2 Snapshots

Where the cursor was in the original line was cursor way down below!

    This works in my installation. Newline problem is mostly due to a stray newline at the end of snippet file and not due to the mode-require-final-newline variable. Is this the complete .emacs file? – nitishch Sep 16 '15 at 19:35
  • My emacs file is a collection of different people's code (I don't know elisp, not yet). I'm also experiencing some funny behaviour in org-mode when I do C-c C-x C-l to preview latex fragments within $ symbols. It used to display math correctly, like inline, now instead it gives the preview tiny and the cursor goes way down from the line it was. I'll try to post a snapshot of this error and the entire .emacs file in my original post, please have a look at it. – WobblyWindows Sep 16 '15 at 20:51
  • Is everything ok in my .emacs file? Are there conflicting lines? – WobblyWindows Sep 17 '15 at 13:27
  • Instead of posting your entire .emacs, it's better to find the minimum amount that's needed to trigger the error. The bisection technique can help with this. – npostavs Sep 17 '15 at 13:30
  • I've commented out almost everything in my .emacs file except these few lines: (add-hook 'LaTeX-mode-hook 'turn-on-reftex) (setq reftex-plug-into-AUCTeX t) ;;; a key for tilde symbol (global-set-key [f2] "~") ;; visual line word wrapping (global-visual-line-mode t) . The problem is still persisting, both with the snippet and org-mode math preview. Are there any known conflict between AUCTeX and YASnippet or YASnippet and Org-mode that can be fixed? What could it possibly be, at this point? – WobblyWindows Sep 17 '15 at 17:52

I changed my .emacs file by copy/pasting some lines regarding this same problem from another post in stackexchange. Here's how it looks now.

 ;; yasnippet
 (add-to-list 'load-path "~/.emacs.d/elpa/yasnippet-0.8.0")
 (require 'yasnippet)
 (setq yas-snippet-dirs '("~/.emacs.d/elpa/yasnippet-0.8.0/snippets"))
;; (setq-default mode-require-final-newline nil) 
(yas-global-mode 1)
(defun disable-final-newline () (interactive) (set (make-local-variable 'require-final-newline) nil))

I also added Andrea Crotti's YASnippets collection to my YASnippets path and tried to write some of my own. For example:

# -*- mode: snippet -*-
# name: si
# key: si
# --
\SI{${1:number}}{${2:units}}$0

I reloaded all the snippets via the 'YASnippets' menu of LaTeX mode and now things are working fine. I'm not sure those lines fixed the problem because Org-mode still gives me trouble as reported in the pictures above. It seems as if the math preview-box is too big and can't fit the regular lines. I'm inclined to ask a new question on that matter but for now I managed to (temporarily) fix YASnippet's placeholder lining problem.
