I have my type of objects `Mvp` (for “multivariate polynomials”) and I have overloaded `latexstring` for them. For example, for a certain polynomial `p` I have at the repl:

```julia-auto
julia> latexstring(p)
L"$x^3+3x^2y+3xy^2+y^3$"

```

If in Pluto I evaluate `latexstring(p)` I get a nice display. So I want that whenever I evaluate an `Mvp`, it is displayed in Pluto via its `latexstring`. I thought the following would do the job:

`Base.show(io::IO,::MIME"text/html",p::Mvp)=print(io,latexstring(p))`

and for instance it works perfectly in an `IJulia` notebook. But it does not work in Pluto, it shows the unrendered string. What is the solution?

For some reason Jupyter automatically interprets `$...$` inside HTML as LaTeX and renders it with MathJax:

However, in general I wouldn’t expect HTML rendering to do this, so it’s not so surprising that it doesn’t work in Pluto. I think you need to display in a format like `text/latex` or `text/markdown` that [Pluto supports](https://github.com/JuliaPluto/Pluto.jl/blob/main/src/runner/PlutoRunner/src/display/mime%20dance.jl) and which should should handle LaTeX equations, i.e.

```julia-auto
Base.show(io::IO, ::MIME"text/latex", p::Mvp) = print(io, latexstring(p))

```

Thank you for the tip!  
This works _after_ deleting the method `Base.show(io::IO, ::MIME"text/html", p::Mvp)` which seems to be preferentially called
