Re: elisp questions for Advanced Closing brackets function

[Lorenzo Isella]

Dear All,
My questions are even more basic than the ones expressed here.
I would like to do some "trivial" emacs customization.
First of all, I should say I am not a lisp programmer at all and that
my .emacs file
is at the present a patchwork of examples I found online.
Yet, what I would like to do should be quite simple.
A few examples:
(1) I often use auctex, but when I open a tex file I would like to
have pdflatex as
the default, so I would like to skip the tedious C-c C-t C-p.
How can I include this command in the .emacs file? Obviously it should
be executed only when I am opening and reading a .tex file.
(2) Here is something I do not understand.  I found online the
following handy function for automatically inserting another "$" sign
when I type one and moving back the cursor:

   (defun TeX-insert-dollar () "custom redefined insert-dollar" (interactive)
     (insert "$$")       ;in LaTeX mode, typing "$" automatically insert "$$"
     (backward-char 1)) ;and go between them: no more matching problems!

Then, I tried doing something similar when quoting:

   (defun TeX-insert-quote () "custom redefined insert-quote" (interactive)
     (insert "``''")
     (backward-char 2))

and it worked. However, when I tried doing the same with brackets:

   (defun TeX-insert-curly () "custom redefined insert-curly" (interactive)
     (insert "{}")
     (backward-char 1))

I did not get any error message, but it surely does not work on my
system.

Why is that? Is the emacs lisp documentation mentioned in the email I
am quoting the right place to look for answers?
Cheers

Lorenzo
