Loading =tex.el= immediately instead of lazily ensures proper initialization of

[[https://en.wikipedia.org/wiki/AUCTeX][AUCTeX]]. For instance, the ~TeX-master~ safe local variable in the =tex.el=
|
||||
[[https://en.wikipedia.org/wiki/AUCTeX][AUCTeX]]. In particular, the ~TeX-master~ safe local variable in the =tex.el=
|
||||
elisp library file has no autoload cookie. Without prior loading of =tex.el=,
|
||||
Emacs will complain that ~TeX-master~ is no safe local variable in case it reads
|
||||
a LaTeX file that sets ~TeX-master~. Listing [[lst:require-auctex]] initializes
|
||||
[[https://en.wikipedia.org/wiki/AUCTeX][AUCTeX]] properly for LuaTeX or LuaLaTeX. In case the output of =LuaLaTeX= has
|
||||
missing fonts, listing [[lst:update-lualatex-opentype-font-name-database]] defines a
|
||||
function to update the =OpenType Font= name database for =LuaLaTeX=. Finally,
|
||||
out of the box, [[https://en.wikipedia.org/wiki/AUCTeX][AUCTeX]] does not indent text between square brackets. The code
|

in listing [[lst:configure-auctex]] corrects this by advising to override

a LaTeX file that sets ~TeX-master~. The list below summarizes the main [[https://en.wikipedia.org/wiki/AUCTeX][AUCTeX]]
|
||||
configuration objectives:
|
||||
1. Listing [[lst:require-tex]] initializes [[https://en.wikipedia.org/wiki/AUCTeX][AUCTeX]] properly for =LuaTeX= or
|
||||
=LuaLaTeX=.
|
||||
2. Listing [[lst:require-tex]] also enables [[https://git.savannah.gnu.org/cgit/auctex.git/patch/?id=f464242eab092e610dda6b654e6fd197ef649d3eAA][indenting between square brackets]]
|
||||
which is a recent feature.
|
||||
3. Listing [[lst:update-lualatex-opentype-font-name-database]] defines a function to
|
||||
update the =OpenType Font= name database for =LuaLaTeX= when the output of
|
||||
=LuaLaTeX= shows missing fonts.
|
||||
4. Listing [[lst:configure-bibtex]] configures the Emacs =bibtex= library to use the
|
||||
LaTeX =BiBTeX= dialect for backwards compatibility.
|
||||
5. Listing [[lst:configure-font-latex]] disables font scaling of section titles.
|
||||
6. Listing [[lst:configure-latex]] configures =latex= for a full featured
