LaTeX

[ChrisRackauckas]

Can you input LaTeX into Weave? Is it in the docs?

[mpastell]

You can and sort of.
See: http://weavejl.mpastell.com/stable/usage/#supported-formats, http://weavejl.mpastell.com/stable/usage/#noweb-format and outdated sample https://github.com/mpastell/Weave.jl/blob/master/examples/julia_latex.texw that needs to be fixed...

Also language-weave recognizes .texw files in Atom and does correct syntax highlighting and you can run code from the chunks.

Is there a way to have chunks of LaTeX within a .jmd file similar to R Markdown's $\hat y$ syntax? I didn't see this an any examples. Thanks.

[mpastell]

Yes. You can use LaTeX math with the same syntax as rmarkdown. The default markdown flavor is Julia markdown.

[krcools]

Is there a way to have things verbatim included in the resulting tex file? (cf raw cells in Jupyter notebooks) This would enable the definition of macros...

[joshualeond]

I was able to use LaTeX similar to rmarkdown with the $ syntax as you mentioned. The only difference I saw was that the double $$ syntax wasn't supported for multiline equations. Is that correct? Also, It would be really cool to have a weave button in Juno similar to the knit button in RStudio. Not to take away from the great work you've done here, I just think it would be a nice feature in the future. Thanks again.

For reference:
The markdown flavor used in html and pdf output (md2html and md2pdf formats) is Julia Markdown: https://docs.julialang.org/en/stable/manual/documentation/#Markdown-syntax-1.

rmarkdown uses Pandoc so if you need features from Pandoc markdown you can use pandoc, pandoc2html or pandoc2pdf formats.

[mpastell]

If you want a Weave button in Juno it's probably better to open issue in Juno repository. Or if you can add it to https://github.com/mpastell/language-weave I'd be happy to include it.

FYI I found out to add LaTeX macros I need to use double-tic:

``
\def\foo{x^2}
``

Actually, LaTeX support seems quite brittle: in my file if I have a single surface plot, it works, but if I add a second surface plot, none of the LaTeX renders.

Is there a way to debug what's causing the problem?

This doesn't seem to work for me. The defined macro needs to be in the same equation block as location it's used, then it works. That almost defeats the purpose of defining a macro.

I hope we can define document macros soon. Otherwise I'm just going to stick to .tex files.

There seems to be inconsistency between HTML and PDF. For PDF I managed to get it working using a template, though you need to avoid double brackets {{ by adding a space in between.

Anyone know how to get LaTeX block (i.e. not inline) equation environments $$eqn$$ to work inside of markdown enumerate?

No matter what I do, if I use the block equation environment the text below no longer follows the enumerate.

i.e.

1. enumerated
2. enumerated

$$
math
$$

not part of enumerated

I have tried indenting the math, but weave throws an error.

Is there any way to make it so the environment would behave as though I had block equation environment inside a latex enumerate?

Solution:

You can indent the environment only if it is all on one line.

1. item
2. item
    continued

    $$math$$

    part of enumerated

Still not sure how this is meant to work for something more complicated like a multiline equation.
