\text choice in recipes

[ChrisRackauckas]

I'm cleaning up the Symbolics latexify output:

You can see that the compound equations don't look quite right. I am fixing the + stuff manually, but I don't know how to make the symbol names use \text{capacitor.v} instead of just being directly written out. Also an option for \textrm would be nice.

I'm not sure I understand the problem, could you write an mwe?

[ChrisRackauckas]

using Symbolics, Latexify
@variables myvariable
latexify(myvariable)

produces myvariable and not \text{myvariable}

[gustaphe]

Something like

diff --git a/src/latexify_recipes.jl b/src/latexify_recipes.jl
index e7c9ac54..296c8c32 100644
--- a/src/latexify_recipes.jl

 recipe(n) = latexify_derivatives(cleanup_exprs(_toexpr(n)))
 
-@latexrecipe function f(n::Num)
+@latexrecipe function f(n::Num; variable_style="")
     env --> :equation
     cdot --> false
     fmt --> FancyNumberFormatter(5)
 
-    return recipe(n)
+    isempty(variable_style) && return recipe(n)
+    return LaTeXString(string("\\", variable_style, "{", recipe(n), "}"))
 end
 
 @latexrecipe function f(z::Complex{Num})

would do it if Num was just a single variable. I don't know exactly how to get around the problem that

julia> set_default(; variable_style="text")
julia> @variables x y
julia> latexify(x+y)
L"\begin{equation}
\mathrm{x + y}
\end{equation}
"

, it arises from the fact that x + y is a Num. I don't know the Symbolics internals, is there a type that encapsulates the concept of a single variable?

Thanks, that's all I needed to see. I was able to figure out how to add it directly JuliaSymbolics/Symbolics.jl#1305
