Interpolating LaTeXString into Markdown

[zfengg]

Recently I find the output of latexify() doesn't render well in markdown cell at the new versions included v0.14.8 and v0.14.7. However, it works well in v0.14.5.

Comparison.

v0.14.5

VS

v0.14.8

env

Both run in Chrome on Windows 10.

Also, the render doesn't work on Binder on which the Pluto version is 0.14.7.

remark

Right now I pin to 0.14.5 but I hope I can walk around this in the future versions to enjoy the amazing Pluto! Thanks.

Unfortunately, this 'worked' because of a bug, and I fixed that bug: https://github.com/fonsp/Pluto.jl/pull/1164/files#diff-98c649aba98aa3bee0202b56f4e1d1e44ae620b564690ad53b114b49b03d69fcL351-R351

Markdown interpolation does not support latex objects (it will render them as text), you have to wrap them in a Markdown.LaTeX. You can use this helper function:

latexify_md(args...; kwargs...) = Markdown.LaTeX(repr(MIME"text/latex"(), latexify(args...; kwargs...)))

or more general for LaTeXStrings:

wrap_tex(x) = Markdown.LaTeX(repr(MIME"text/latex"(), x))

I see. Thanks a lot!

Can you think of a good way to use this as a html show method?

Base.show(io, m::MIME"text/html", x::LaTeXString) = show(io, m, Markdown.LaTeX(repr(MIME"text/latex"(), x)))

doesn't work. I don't want to have to define a latexify_md, latexraw_md, latexequation_md when just allowing interpolating a latexstring would give me the full gamut of Latexify.

@gustaphe You need to wrap the Markdown.LaTeX in a Markdown.MD(...).

The problem them is that you Markdown's ability to automatically switch between display math and inline math, and I don't see a way to resolve that using the html show method. Let me try something else...

Interpolating LaTeX is a missing feature in Markdown, and LaTeXString.jl confuses the ecosystem.

This works:

begin
	using Latexify
	using LaTeXStrings
	
	Markdown.html(io::IO, ls::LaTeXString) = 
		Markdown.html(io, Markdown.LaTeX(
			repr(MIME"text/latex"(), ls)
		))
	
	Markdown.htmlinline(io::IO, ls::LaTeXString) = 
		Markdown.htmlinline(io, Markdown.LaTeX(
			repr(MIME"text/latex"(), ls)
		))
end

This works:

begin
	using Latexify
	using LaTeXStrings
	
	Markdown.html(io::IO, ls::LaTeXString) = 
		Markdown.html(io, Markdown.LaTeX(
			repr(MIME"text/latex"(), ls)
		))
	
	Markdown.htmlinline(io::IO, ls::LaTeXString) = 
		Markdown.htmlinline(io, Markdown.LaTeX(
			repr(MIME"text/latex"(), ls)
		))
end

This works. Cannot you add it to Pluto? It's a bit of complicated to use LaTeXStrings now in Pluto.

Greetings,

None of these methods seem to work in Pluto notebook v.0.19.29. Can anyone provide modifications of any of these solutions so it continues to work in the newer version of Pluto notebook?
