Loading several latex classes for ox-latex

Loading several latex classes for ox-latex

[Julien Cubizolles]

How can I run several add-to-list after a given package is loaded ? I
could of course do multiples:

(eval-after-load 'package_name '(add-to-list 'element 'list))

but I'm sure there's a more elegant way.

I tried the following:
--8<---------------cut here---------------start------------->8---
(eval-after-load 'ox-latex
  (progn '(add-to-list 'org-latex-classes
		       '("mpsi_beamer" "\\documentclass{mpsi_beamer}\n [NO-DEFAULT-PACKAGES]"
			 ("\\section{%s}" . "\\section*{%s}")
			 ("\\subsection{%s}" . "\\subsection*{%s}")
			 ("\\subsubsection{%s}" . "\\subsubsection*{%s}")
			 ))
	 '(add-to-list 'org-latex-classes 
		       '("mpsi" "\\documentclass[cours,Version,colonne]{mpsi}"
			 ("\\section{%s}" . "\\section*{%s}")
			 ("\\subsection{%s}" . "\\subsection*{%s}")
			 ))
	 ))
--8<---------------cut here---------------end--------------->8---

but only the second one (mpsi) is loaded.

that's because your (progn) is unquoted and thus evaluated at the same
time as eval-after-load, i.e. it returns its last value (which is the
second add-to-list form) and that is what is being added to the
eval-after-load list. What you want is the whole (progn) added there, so
an easy fix probably is to say '(progn ...) *and* remove the quotes
around the calls to add-to-list.

Thank you, you were right.
