#+TITLE: :lang latex

* Module Description
Provide a helping hand when working with LaTeX documents.

** Feature:
+ Sane defaults
+ Fontification of many popular commands
+ Pretty indentation of wrapped lines using the ~adaptive-wrap~ package
+ Spell checking with ~flyschek~
+ Change PDF viewer to Okular or ~latex-preview-pane~
+ Bibtex editor
+ Autocompletion using ~company-mode~
+ Ivy or Helm for selecting bibliography
+ Compile your .tex code only once using LatexMk


* Customization

** Custom Variables
Two custom variables state where AUCTeX will search for bibliography files and their corresponding PDFs.
Set these variables in your private configuration with:
#+BEGIN_SRC emacs_lisp
(set! :latex-bibtex-file "./your/bib/file.bib")
(set! :latex-bibtex-pdfs-dir "./dir/with/bib/pdfs/")
#+END_SRC
If the variables are not set, they are ignored.

** Choose View Program
You have four options to choose from for the viewer of your PDF rendered files.
*** Okular
Use Okular as default PDF viewer.

Activate with the flag '+okular' of the latex module in your private init.el.
#+BEGIN_SRC emacs_lisp
(latex +okular)
#+END_SRC

*** Skim
For Mac users. Use Skim to preview your PDFs.

Activate with the flag '+skim' of the latex module in your private init.el.
#+BEGIN_SRC emacs_lisp
(latex +skim)
#+END_SRC

*** PDF Tools
Use the PDF Tools package to preview your PDFs. Requires the tools module ~pdf~ enabled in your configuration.
#+BEGIN_SRC emacs_lisp
(:tools pdf)
#+END_SRC

Activate with the flag '+pdf-tools' of the latex module in your private init.el.
#+BEGIN_SRC emacs_lisp
(latex +pdf-tools=)
#+END_SRC

*** Preview Pane
You may wish to use the old school package ~latex-preview-pane~ instead of the
other alternatives. ~latex-preview-pane~ uses a ~DocView~ instead.

Activate with the flag '+preview-pane' of the latex module in your private init.el.
#+BEGIN_SRC emacs_lisp
(latex +preview-pane)
#+END_SRC

** LatexMk
Use LatexMk instead of normal LaTeX to compile documents. LatexMk only needs to
run once to get all references, bibliography and other things right.

Activate with the flag '+latexmk' of the latex module in init.el.
#+BEGIN_SRC emacs_lisp
(latex +latexmk)
#+END_SRC

You can enable both a custom view program and LatexMk with a call such as:
#+BEGIN_SRC emacs_lisp
(latex +latexmk +okular)
#+END_SRC
