org-preview-latex-fragment ignores \includes in the LATEX_HEADER

org-preview-latex-fragment ignores \includes in the LATEX_HEADER

[Stefan Otte]

Hey,

I'm using orgmode with lots of LaTeX for equations. A typical document
start with

  #+TITLE: Some Title
  #+LaTeX_HEADER: \include{commands}

commands.tex contains commands like:
  \newcommand{\RRR}{{\mathbb{R}}}

The pdf export works flawlessly, however `org-preview-latex-fragment`
seems to ignore "\include{commands}", i.e., equations that use
commands that are defined in commands.tex are rendered as blank/empty
image.

Is it the intended behavior that `org-preview-latex-fragment` ignores
"\include", is it a bug, or is there a better way to do it?


Best,
 Stefan

afaik \include doesn't work in LaTeX headers; you'll have to use \input
there.

Could you try to use \input?

Best regards

Hey,

"\input" does not solve the problem. Still no preview images. (The pdf
export still works as expected.)


Best,
 Stefan

Fragments are islands unto themselves with their own special
handling. See the doc for the variable org-format-latex-header.

Maybe create a style file and then use

,----[ C-h v org-latex-packages-alist RET ]
| org-latex-packages-alist is a variable defined in `org.el'.
| 
| Documentation:
| Alist of packages to be inserted in every LaTeX header.
| 
| These will be inserted after `org-latex-default-packages-alist'.
| Each element is either a cell or a string.
| 
| A cell is of the format:
| 
|     ("options" "package" SNIPPET-FLAG)
| 
| SNIPPET-FLAG, when non-nil, indicates that this package is also
| needed when turning LaTeX snippets into images for inclusion into
| non-LaTeX output.
| 
| A string will be inserted as-is in the header of the document.
| 
| Make sure that you only list packages here which:
| 
|   - you want in every file;
|   - do not conflict with the setup in `org-format-latex-header';
|   - do not conflict with the default packages in
|     `org-latex-default-packages-alist'.
| 
| You can customize this variable.

Note bit about LaTeX snippets.
