You mentioned you used custom to modify the org-latex-classes variable. Does the code in the custom 'block' of your init file have beamer as one of the classes? My suspicion is that when you added your exam class, for some reason, beamer had not been loaded and was not yet in the variable definition. When you edited it to add your exam class it has saved a version without beamer as a class. When you start emacs, with the new init and run order, the code > (unless (assoc "beamer" org-latex-classes) > (add-to-list 'org-latex-classes > '("beamer" > "\\documentclass[presentation]{beamer}" > ("\\section{%s}" .

"\\subsubsection*{%s}")))) is executed and beamer is added, but then your custom settings are evaluated and the variable is reset with the version you added the exam class to, which has no beamer entry, is used to reset the variable and the beamer setting is lost. My guess is that at the time you customized the variable, beamer was not loaded and so the beamer class was not added. Now, when you start emacs, beamer is being loaded before your custom block is evaluated and your customisation is overriding the value added by beamer when it is loaded. There are numerous reasons why this might occur. It may simply be something subtle arising from the new load order (for example, previously, such a value may have been fine as your custom settings would be loaded before the ox-beamer library, but now the library is being loaded first and then custom settings?). This could be likely if you are using a custom block saved with an earlier version of emacs. I would start by deleting the org-latex-classes customization and try adding it again to see if that fixes the problem. This is one reason I rarely use customise - I prefer to have the code in my own init file so that I can see exactly when everything is run.

The custimise interface is fairly basic and makes a few assumptions which may not hold once you start altering the order of initialisation and package loading. While it all works fine 80% of the time, it may fail for more complex situations and the reality is, Org is large and complex. Strictly speaking, I don't think it is a bug. The problem is getting the right balance of what to load and what to leave for the user to decide to load. If you never use beamer, then having all the beamer stuff loaded by default is only going to slow down start up (though I do think people are way too obsessed with startup time these days! I start emacs about once per week and only that often because I shutdown my laptop on the weekend when I leave work!). If beamer is not loaded when you customise org-latex-classes, then it won't be in the variable and if it isn't in the variable, it cannot be saved into the custom block. If you then later decide to load it and it is loaded before your customisation is loaded, then the value it adds to org-latex-classes is lost. If on the other hand we 'hard code' it into the variable so it doesn't depend on whether ox-beamer is loaded, then a definition will exist which won't work when the user tries to use it as ox-beamer is not loaded. Previously, I think custom blocks were loaded at the start of your init, so before org was loaded, so this was less of an issue. No with the early init stuff, things are not quite the same (a lot of guess work here!).

The problem is problem with custom, I thought the logic would be like this. 1. Emacs is started, 2. The customization is loaded, which in my case is (custom-set-variables '(org-latex-classes '(("article" "\\documentclass[12pt]{article}" ("\\section{%s}" . "\\section*{%s}") ("\\subsection{%s}" . "\\subsection*{%s}") ("\\subsubsection{%s}" . "\\subsubsection*{%s}") ("\\paragraph{%s}" . "\\paragraph*{%s}") ("\\subparagraph{%s}" . "\\subparagraph*{%s}")) ("report" "\\documentclass[12pt]{report}" ("\\part{%s}" . "\\part*{%s}") ("\\chapter{%s}" . "\\chapter*{%s}") ("\\section{%s}" . "\\section*{%s}") ("\\subsection{%s}" . "\\subsection*{%s}") ("\\subsubsection{%s}" . "\\subsubsection*{%s}")) ("book" "\\documentclass[12pt]{book}" ("\\part{%s}" . "\\part*{%s}") ("\\chapter{%s}" . "\\chapter*{%s}") ("\\section{%s}" . "\\section*{%s}") ("\\subsection{%s}" . "\\subsection*{%s}") ("\\subsubsection{%s}" . "\\subsubsection*{%s}")) ("exam" "\\documentclass[12pt, addpoints, answers]{exam}" ("\\begin{questions}%%%s" "\\end{questions}" "\\begin{questions}%%%s" "\\end{questions}") ("\\titledquestion{%s}" . "") ("\\begin{parts}%%%s" "\\end{parts}" "\\begin{parts}%%%s" "\\end{parts}") ("\\part[%s] " . "") ("\\begin{subparts}%%%s" "\\end{subparts}" "\\begin{subparts}%%%s" "\\end{subparts}") ("\\subpart[%s] " . "") ("\\begin{solution}[%s]" "\\end{solution}" "\\begin{solution}[%s]" "\\end{solution}")))) Then (require 'ox-beamer) should via add-to-list, add beamer but somehow it does not. I would call this a bug, but Tim said Emacs changed its way of initialization and this could be the result. In any case I will send a bug report, maybe a developer will say something.

Okay and yes, I would have expected this work flow to work fine. Have you tried this sequence in emacs -Q to ensure that the problem is not due to elsewhere in your initialization? -- Eric S Fraga via Emacs 27.0.50, Org release_9.1.14-1035-gfeb442 ^ permalink raw reply [flat|nested] 18+ messages in thread
