cdlatex math keyword commands don't work

init.el: https://paste.sr.ht/~p00f/561c22b96b1660de2409fbdc7e128f3b20edc9fa Math templates don't work in cdlatex mode - for example when I have `$fr$` (or `fr` in `\begin{math}...\end{math}`) and press tab when the cursor is after `r`, it doesn't expand to `\frac{}{}`. I tried this in both `org-cdlatex-mode` and `.tex` files. Things marked as `TEXT` or `TEXT/MATH` in `org-cdlatex-command-help` work, the ones marked as `MATH` don't - pressing tab just moves the cursor out of the math environment What's wrong? Edit: solved by installing auctex

You need to turn on cdlatex. Here's what I use: (use-package cdlatex :hook ((LaTeX-mode . turn-on-cdlatex) (org-mode . turn-on-org-cdlatex) (cdlatex-tab . LaTeX-indent-line))) The `(cdlatex-tab . LaTeX-indent-line)` takes care of indenting after cdlatex does its stuff.

I turn on cdlatex for specific buffers using `M-x org-cdlatex-mode RET` for org and `M-x cdlatex-mode RET` for plain .tex, is that not enough? Note that non-math templates like `ct<TAB>` for `\cite{}` work, only math templates like `sq<TAB>` for `\sqrt{}` don't even though they are in a math environment like `$...$` or `\begin{math}...\end{math}` Adding only the last hook gives me cdlatex-tab: Autoloading file /home/username/.config/emacs/straight/build/cdlatex/cdlatex.elc failed to define function LaTeX-indent-line [5 times] Edit: I get that error even after adding the other two hooks and doing `M-x straight-rebuild-package RET cdlatex RET`

That's probably a function exclusive to AUCTeX. I seem to remember strange behavior with cdlatex when some packages got updated, but Emacs hasn't been restarted. When's the last time you restarted Emacs?

Yep, it was because I hadn't installed auctex 😅. I saw > You need to install ‘cdlatex.el’ and ‘texmathp.el’ (the latter comes also with AUCTeX) on https://orgmode.org/manual/CDLaTeX-mode.html but read somewhere that texmathp.el is built into emacs 21.3 onwards (clearly that was wrong)
