Re: patch: add custom latex->html conversion command
Thanks for the feedback. I've filled out the form you sent and sent it
to the email listed.
Adjusted patch below. I didn't add a value to the customization. I'm
honestly not very familiar with the customize interface since I never
use it. Is that a default value if the user selects string from the
customize interface? If it is I think it's probably best to leave it
blank since this is really meant to be open-ended. For instance, I doubt
the example I give would work on windows, so that might be more
confusing than helpful in that case. What do you think? Happy to set it
to whatever.
Matt

Subject: [PATCH] add custom command option when converting latex fragments to
html
* lisp/org.el (org-latex-to-html-convert-command): Add custom command
option to convert a latex fragment directly into HTML.
(org-format-latex): Add condition for this command to org-format-latex.
(org-format-latex-as-html): Command that ultimately does the
conversion work. It uses the user-specified command and applies to
the latex fragment. It then returns the resulting HTML.
* lisp/ox-html.el (org-html-with-latex): Document 'html symbol.
(org-html-format-latex): This custom HTML conversion, like mathjax,
doesn't require preprocessing.
(org-html-latex-fragment): Add condition to org-html-latex-fragment
for html symbol.
This allows you to set a custom command
`org-latex-to-html-convert-command' that will take as input a latex
fragment and use it to generate html for export. This is very
open-ended in the sense that you can use any shell-command you
want. I've added the ability in order to use latexml, but you could
use any other tool that generates HTML output text.

Re: patch: add custom latex->html conversion command
Bastien, Thanks for the reply. I’ll look into it. However, I’d initially ruled that out because the final output is meant to be an image. So, to get just text insertion into the html output I imagine would be a bit of a hack. For instance what to set image-converter to etc. Matt On Sun, Feb 16, 2020 at 4:06 PM Bastien wrote: > Hi Matt, > > Matt Huszagh writes: > > > The patch below allow's you to provide your own shell command the > > generates HTML from a latex fragment and places the output directly in > > the exported HTML file. > > Can you get the same output by configuring a new symbol in > `org-preview-latex-process-alist' then setting `org-html-with-latex' > to this new symbol? > > I've not tested it, so perhaps it does not work. > > But any patch about adding latexmlc support should surely look in this > direction first. > > HTH, > > -- > Bastien >

Hi Matt, Matt Huszagh writes: > The patch below allow's you to provide your own shell command the > generates HTML from a latex fragment and places the output directly in > the exported HTML file. Can you get the same output by configuring a new symbol in `org-preview-latex-process-alist' then setting `org-html-with-latex' to this new symbol? I've not tested it, so perhaps it does not work. But any patch about adding latexmlc support should surely look in this direction first. HTH, -- Bastien
patch: add custom latex->html conversion command
Hi all,
The patch below allow's you to provide your own shell command the
generates HTML from a latex fragment and places the output directly in
the exported HTML file.
I've added this feature to be able to use latexml for processing latex
fragments to HTML. Unfortunately, mathjax can't process macros from the
siunitx package, but latexml can. Here's how I use it
(setq org-html-with-latex 'html)
(setq org-latex-to-html-convert-command "latexmlc 'literal:%i' --profile=math
--preload=siunitx.sty 2>/dev/null")
Any/all feedback appreciated!

envisioned this for use with latexml, but there's nothing preventing
you from using something else.
