Hi, thanks for the report. I can't get it to reproduce the same error you're getting yet, could I get the output of status --manifest so we can see what the exact differences in package versions are?

In addition can you try

julia> MathJaxRenderer.Librsvg_jll.rsvg_convert() do bin
           run(`$bin --version`)
       end
rsvg-convert version 2.42.2

to see whether rsvg-convert isn't broken somehow?

Does exporting an SVG file work?

write("fraction.svg", Math("\\frac{1}{1 + x}"))

And if so could you attach the generated SVG file, thanks.

Thank you!

Pretty weird.. we've got very similar installs. Let's rule out anything that's not an actual dependency causing this. Can you check in an isolated project environment like below:

[MichaelHatherly]

One of the only similar issues I've managed to find searching is https://gitlab.gnome.org/GNOME/librsvg/-/issues/260, which looks like the same underlying error.

[MichaelHatherly]

We're also a long way behind the most recent version of librsvg in Librsvg_jll, so that might be a contributing issue perhaps.

[originalsouth]

Unfortunately, still the same issue:

Is there an easy way to check if a more recent version would do the job, I have rsvg-convert version 2.52.4 on my system. If so, we should probably make a PR for a version bump of Librsvg_jll.jl in Yggdrasil?

[MichaelHatherly]

You should be able to overwrite the method def that returns the rsvg binary with

julia> MathJaxRenderer.Librsvg_jll.rsvg_convert(f::Function) = f("rsvg-convert")

Do a

julia> MathJaxRenderer.Librsvg_jll.rsvg_convert() do bin
           run(`$bin --version`)
       end

just to check it's picking up the different binary path though. And then try the write call again.

[MichaelHatherly]

If so, we should probably make a PR for a version bump of Librsvg_jll.jl in Yggdrasil?

Yes, if that fixes it then see whether updating the yggdrasil build is possible.

[MichaelHatherly]

Looks like the rsvg options have changed slightly between versions, to actually run write you'll need to do

julia> function MathJaxRenderer.converter(
           f::Math,
           m::MathJaxRenderer.SUPPORTED_MIMES;
           dpi_x = 90,
           dpi_y = 90,
           x_zoom = 1.0,
           y_zoom = 1.0,
           zoom = 1.0,
           keep_aspect_ratio = false,
           background_color = :white,
           unlimited = false,
           kws...,
       )
           MathJaxRenderer.Librsvg_jll.rsvg_convert() do bin
               ext = MathJaxRenderer.extension(m)
               cmd = [
                   bin,
                   "--format=$(MathJaxRenderer.extension(m))",
                   "--dpi-x=$dpi_x",
                   "--dpi-y=$dpi_y",
                   "--x-zoom=$x_zoom",
                   "--y-zoom=$y_zoom",
                   "--background-color=$background_color",
               ]
               keep_aspect_ratio && push!(cmd, "--keep-aspect-ratio")
               unlimited && push!(cmd, "--unlimited")
               take!(MathJaxRenderer.check(MathJaxRenderer.exec(Cmd(cmd), MathJaxRenderer.svg_converter(f; kws...))).io)
           end
       end

as well to remove the zoom option.

[originalsouth]

Great! That fixes the problem:

[MichaelHatherly]

Great, that's some progress. Next step is to see whether the build script is able to be updated, no idea how simple that one will be to get done.

[originalsouth]

I can make an issue on yggdrasil and link to this one later today? Thanks a lot for you help in the meanwhile!

[MichaelHatherly]

Yeah, please do.

[originalsouth]

We ran into the same issue: "librsvg needs at least rustc version 1.52"... not sure how to continue...

[MichaelHatherly]

We could consider adding an option to use the system rsvg-convert if it exists. I've not really not the spare time right now to do that, but you're welcome to take a took at doing that if you want. Otherwise, we'll just need to wait on the yggdrasil issue being solved.

[originalsouth]

I would not mind spending some time fixing this properly -- I think it is not such a big fix. What would be the desired behavior? If a system rsvg-convert is available use that one with the patched interface?

[MichaelHatherly]

I've not really thought through how it should work. Could be one of:

1. Try with the provided rsvg-convert, if that fails then try using a system provided version if available.
2. Have a keyword argument that sets the rsvg-convert binary to use.
3. Have a global setting or environment variable that sets the binary to use.

For any of those we'd need to handle having the correct set of cmd line arguments passed to the binary such that it doesn't fail (like in the zoom case above).

[originalsouth]

Fixed by PR #10. Cheers!

[MichaelHatherly]

Thanks for sorting this out @originalsouth, I'll tag a 0.2 version shortly.
