TeXParseError: unexpected error while parsing #39

ederag · 2022-07-01T16:08:03Z

It looks like MathTeXEngine is used instead of MakieTeX,
in recent Makie versions (visible in the summary head), and julia-1.7.3.

It happens both with code that used to work about a month ago, and with the README.md example:

Interesting, thanks for the report - I haven't used MakieTeX in a couple weeks. I can probably patch this tomorrow, since it should just be a matter of adjusting the method signatures which are available.

asinghvi17 · 2022-07-03T04:50:47Z

Ugh...this is somewhat harder than I thought, and will require some refactors in Makie itself.

Basically, the text dispatches got changed, and everything now goes through text!(positions...; text = AbstractString[...]), which is not actually possible to dispatch on in plot!. So, I'll have to modify that method in Makie.

Currently, I'm thinking of doing two things to make it more flexible overall, and allow MakieTeX to keep functioning:

Allow arbitrary types to be passed to the final text call (this will allow us to use Pango layouts as well, in time)
Delete and replot the text plot whenever the type passed in to it changes. This may be a little fragile, but it does make text extremely flexible.

Mark2000 · 2022-12-01T23:29:22Z

Is this package still being maintained? Would love to use it, but this issue seems to break it completely.

BeastyBlacksmith · 2022-12-02T14:21:51Z

I'd say anything that stayed here and not moved to MakieOrg is unmaintained.

@SimonDanisch these can be archived, no?

SimonDanisch · 2022-12-02T15:05:52Z

I guess MakieTeX is in the twilight zone of not being actively maintained enough to get moved to MakieOrg (a.k.a it's not working), but it's definitely of value, so hopefully maintenance will be picked up again at some point...
Of course, if it noises up JuliaPlots, we can move it back to @asinghvi17, or some other org ;)
