Hello,
If I have a latex file mystyle.tex that contains:
\newcommand{\myBigEquation}{b=23}
and then have this in my org file:
#+LATEX_HEADER: \usepackage{/path/to/mystyle}
I can use it conveniently like this:
\begin{equation}
\myBigEquation
\end{equation}
and that exports fine to pdf but not to odt. I am fairly sure it used
to work (around 7th Oct). Can anyone confirm this?
Myles

I am happy that there is someone out there interested in and using stuff that I have spent some efforts on. > Hello, > > If I have a latex file mystyle.tex that contains: > > \newcommand{\myBigEquation}{b=23} > > and then have this in my org file: > > #+LATEX_HEADER: \usepackage{/path/to/mystyle} > > I can use it conveniently like this: > > \begin{equation} > \myBigEquation > \end{equation} > > and that exports fine to pdf but not to odt. I am fairly sure it used > to work (around 7th Oct). Can anyone confirm this? I am using the very latest version in the git. While exporting to odt using 1. dvipng - I see no issues [1] 2. mathml - You need to register your command file with -ncf argument. For example, if I put the mystyle.tex in the same directory as exported .org file and add the -ncf argument to the converter as below #+begin_src emacs-lisp (setq org-latex-to-mathml-convert-command "java -jar %j -ncf mystyle.tex -unicode -force -df %o %I ") #+end_src I see that your sample file gets exported just fine. Side Note: ========== 1. You don't have to export the whole file to see whether the latex-mathml conversion is sane. You can mark - as in marking a region - the LaTeX fragment in your org file and do a M-x org-create-math-formula. You will see something like this echoed in you *Messages* buffer. ,---- M-x org-create-math-formula | Mark set [2 times] | Mark activated | Wrote ~/tmp-myles/ltxmathml-in3272esr | Running java -jar ~/tmp-odt/mathtoweb.jar -ncf mystyle.tex -unicode -force -df ltxmathml-out3272r2x ltxmathml-in3272esr | <?xml version="1.0" encoding="UTF-8"?> | <math xmlns="http://www.w3.org/1998/Math/MathML"> | <mrow> | <mspace width="1.00em" /> | <mi>b</mi> | <mo>=</mo> | <mn>23</mn> | </mrow> | </math> `---- 2. I am copy pasting the extra "stuff" that gets attached to the latex fragment before it get "latex" ed and "dvipng"ed. latex-to-mathml converter ignores *all* of the stuff that goes in org-format-latex-header, org-export-latex-default-packages-alist, org-export-latex-packages-alist, org-format-latex-header-extra variables. I think I should build an "ncf" file on the fly based on these variables and pass it to the command line converter. Since I don't know much of latex, can you or someone in the list give me pointers on what would constitute an ncf argument as expected by mathtoweb. I will make the needed changes as required. ,---- See org-create-formula-image | (with-temp-file texfile | (insert (org-splice-latex-header | org-format-latex-header | org-export-latex-default-packages-alist | org-export-latex-packages-alist t | org-format-latex-header-extra)) | (insert "\n\\begin{document}\n" string "\n\\end{document}\n") | (require 'org-latex) | (org-export-latex-fix-inputenc)) `---- ,---- temporary tex file [see LATEX-HEADER at the end] | \documentclass{article} | \usepackage[usenames]{color} | \usepackage{amsmath} | \usepackage[mathscr]{eucal} | \pagestyle{empty} % do not remove | \usepackage{pdfpages} | \usepackage[utf8]{inputenc} | \usepackage[T1]{fontenc} | % Package fixltx2e omitted | \usepackage{graphicx} | % Package longtable omitted | % Package float omitted | % Package wrapfig omitted | \usepackage{soul} | \usepackage{t1enc} | \usepackage{textcomp} | \usepackage{amssymb} | % Package hyperref omitted | \tolerance=1000 | % The settings below are copied from fullpage.sty | \setlength{\textwidth}{\paperwidth} | \addtolength{\textwidth}{-3cm} | \setlength{\oddsidemargin}{1.5cm} | \addtolength{\oddsidemargin}{-2.54cm} | \setlength{\evensidemargin}{\oddsidemargin} | \setlength{\textheight}{\paperheight} | \addtolength{\textheight}{-\headheight} | \addtolength{\textheight}{-\headsep} | \addtolength{\textheight}{-\footskip} | \addtolength{\textheight}{-3cm} | \setlength{\topmargin}{1.5cm} | \addtolength{\topmargin}{-2.54cm} | | \usepackage{jambu} | \begin{document} | \begin{equation} | \myBigEquation | \end{equation} | \end{document} `---- Footnotes: [1] LaTeX novice here. The method I used is this: Put that style file in one of the local directories and register that directory as a root with the MikTex package manager.

So getting the directory path right with escaping - what with spaces in directories - is always a hair-splitting experience for me. > Myles > > -- ^ permalink raw reply [flat|nested] 6+ messages in thread

Unless it is documented somewehere you are most likely relying on an unintentional side-effect. After some googling, I see that there is promising solution using plastex. The solution is documented in the below file. The customary odt file is attached as a proof-of-concept.
