Incorrect LaTex output in code snippets

[igor-chalenko]

Hi,

Here's the way to reproduce the issue (see attachment for a self-contained example): 1) Use a snippet in comments:

/**
 * @snippet example/custom_operator.cc full
 */

2) In the referenced custom_operator.cc, write something like this:

auto operator^(E1 &&x, E2 &&y) -> Compound<XOR, E1, E2> {
    ....
}

Notice there's NO space between operator and ^.

When LaTex docs are generated, open refman.tex in some validating tool (I use TexStudio), or just run make pdf in latex directory. PDF generation should fail, and the reason for it is this line:

\DoxyCodeLine{\textcolor{keyword}{auto} operator^(E1 \&\&x, E2 \&\&y) -> Compound<XOR, E1, E2>

For comparison, this is what Doxygen generates (tested with 1.8.19):

\DoxyCodeLine{\textcolor{keyword}{auto} operator\string^(E1 \&\&x, E2 \&\&y) -\/> \mbox{\hyperlink{classctaeb_1_1Compound}{Compound<XOR, E1, E2>}} \{}

Now, if I ADD a space between operator and ^, Doxypress generates correct LaTex:

\DoxyCodeLine{\textcolor{keyword}{auto} operator\string^(E1 \&\&x, E2 \&\&y) -\/> \mbox{\hyperlink{classctaeb_1_1Compound}{Compound<XOR, E1, E2>}} \{}

So, apparently the problem boils down to the ^ being unrecognized. Enabling or disabling clang parsing makes no difference, it seems.

My environment: Ubuntu 18.04 + doxypress 1.4.0

Thanks, Igor.

Thanks so much for the report. We'll be looking at this next week.

We have pushed a correction to correctly escape the ^ in Latex. Thanks for reporting this issue.
