error when using `;`

[AntoineSoetewey]

Hello,

For a publication I'd like to add the following notation in ylab:

I have thus tried:

plot(x = rnorm(10),
     y = rnorm(10),
     ylab = TeX(r'($\bar{A}^{a;a \rightarrow i}_{x;n\rceil}$)'))

which gives the error:

It seems to come from ; because this code works fine:

plot(x = rnorm(10),
     y = rnorm(10),
     ylab = TeX(r'($\bar{A}^{a,a \rightarrow i}_{x,n\rceil}$)'))

Any idea how I could fix it?

I use version 0.9.0 of latex2exp, and here is my session info:

Could you try reinstalling 0.9.0? I fixed an issue with parsing semicolons in one of the most recent commits to the branch. On my system,

> TeX(r'($\bar{A}^{a;a \rightarrow i}_{x;n\rceil}$)')

returns the expression:

bar(A)[x*';'*n*group('.', phantom(), rceil)]^{a*';'*a %->% i}

which renders as:

plot(TeX(r'($\bar{A}^{a;a \rightarrow i}_{x;n\rceil}$)'))

(I will also add this expression to the test suite)

(Note: I pushed 0.9.0 to the main branch)

works fine now, thanks a lot!
