Emacs package for previewing LaTeX fragments such as in doxygen comments. Other use-cases are MathJax snippets in html pages and LaTeX equations in stackexchange questions.
Install texfrag via Melpa by <M-x>package-install<RET>texfrag<RET>.
Switch the customization option texfrag-global-mode on to activate texfrag-mode
in all buffers with supported major modes.
If you want to activate texfrag only in a specific major mode add texfrag-mode to
its mode hook. This works out of the box if the major mode is derived from one of
the modes registered in texfrag-setup-alist.
A buffer with activated texfrag has an additional sub-menu "TeX".
There you find menu-items for generating AUCTeX previews at point for
region and for the full document.
The usual key-sequences from AUCTeX such as C-c C-p C-p for Toggle preview at point
are also available.
At the time of writing the list of supported major modes is:
html-mode
$$...$$, \[...\], $...$, \(...\), \begin{...}...\end{...} are recognized in the body of the document&, >, and < are translated to &, >, and < in the LaTeX codeeww-mode
html-modefile://...)sx-question-mode
html-modeprog-mode (formulas in doxygen comments)
\f$...\f$, \f[...\f], \f{...}...\f}, and \f{...}{...\f} are recognized within comments of the source code
(example for the last case: \f{align*}{E=mc^2\f})trac-wiki-mode
^{{{\n#!latex\n...^}}} (thereby ^ stands for beginning of line, and \n for a linebreak), $...$, \(...\), \[...\], and \begin{...}...\end{...}org-mode
$...$, \(...\), \[...\], and \begin{...}...\end{...}org-html-with-latex is set internally to 'dvipng because only that variant works with texfragtexfrag-org-header for texfrag-header-function that ensures that org LaTeX header options are recognizedadoc-mode
latexmath:[...][latexmath]image:...[]:imagesdir: are resolved recursively, as required for adoc:local-attr: for texfrag; The first occurence of an attribute wins. E.g., with the following global attributes texfrag would use /temp as image directory and asciidoctor would use the subdirectory images.
:local-attr: :imagesdir: /temp
:imagesdir: imagesAll major modes derived from the listed modes are automatically also supported.
Please, inspect the help of the variable texfrag-setup-alist for a complete list of supported modes.
texfrag-global-mode and texfrag-preview-buffer-at-start turned on.
