PDF do not include math formulas

[KyrylR]

Observed vs. expected behavior

In the Asciidoctor plugin, when I preview the .adoc file or export it as a PDF, I notice that the math formulas are not rendered correctly. They appear as plain text or not at all in the PDF. The expected behavior is for the math formulas to be rendered correctly, just as they appear in the Asciidoctor preview within the IDE.

Steps to reproduce

1. Create a new .adoc file within IntelliJ IDEA.
2. Add some content that includes math formulas, for instance:

[latexmath]
++++
\frac{n!}{k!(n-k)!} = \binom{n}{k}
++++

3. Preview the document using the Asciidoctor plugin. Note that the formula is correctly rendered in the preview.
4. Export the document as a PDF.
5. Open the PDF and observe that the math formulas are either missing or not rendered correctly.

Thanks for reaching out with this topic. Unfortunately there is no straight good answer for this.

• Asciidocotor PDF (which is used in the plugin) doesn't have math support which I could bundle in the plugin. You might want to try doing a conversion on the command line instead.
• There is an experimental Web PDF support in the IntelliJ plugin which needs to be enabled first. It will render the preview 1:1 (but you'll miss out on, for example, page numbers). See information on enabling the internal mode for this experimental feature.
• Similar to that is opening the HTML in a browser either by using the browser preview, or pressing the HTML button, and creating a PDF from that. With some configuration you should be able to add page numbers
• Convert the document to DOCX first. While that should work, it might be necessary to double-check the converted formulas. This conversion is powered by Pandoc.

See #1321 for a longer discussion. Let me know if this information is helpful.

Ohh, I got it, thanks

It works fine with DOCX
