We've had similar plans for IWYU, and I think we eventually parsed the<br>
TeX source from <a href="https://github.com/cplusplus/draft/tree/master/source" rel="noreferrer" target="_blank">https://github.com/cplusplus/draft/tree/master/source</a><br>
with a simple shell script.<br>
<br>
I didn't do this myself, but I found a couple of examples in our source here:<br>
<br>
// These headers are defined in C++14 [headers]p3. You can get them with<br>
// $ sed -n '/begin{floattable}.*{tab:cpp.c.headers}/,/end{floattable}/p'<br>
lib-intro.tex | grep tcode | perl -nle 'm/tcode{<c(.*)>}/ && print qq@<br>
{ "<$1.h>", kPublic, "<c$1>", kPublic },@' | sort<br>
// on <a href="https://github.com/cplusplus/draft/blob/master/source/lib-intro.tex" rel="noreferrer" target="_blank">https://github.com/cplusplus/draft/blob/master/source/lib-intro.tex</a><br>
<br>
// These headers are defined in C++14 [headers]p2. You can get them with<br>
// $ sed -n '/begin{floattable}.*{tab:cpp.library.headers}/,/end{floattable}/p'<br>
lib-intro.tex | grep tcode | perl -nle 'm/tcode{(.*)}/ && print qq@<br>
"$1",@' | sort<br>
// on <a href="https://github.com/cplusplus/draft/blob/master/source/lib-intro.tex" rel="noreferrer" target="_blank">https://github.com/cplusplus/draft/blob/master/source/lib-intro.tex</a><br>
<br>
(from <a href="https://github.com/include-what-you-use/include-what-you-use/blob/master/iwyu_include_picker.cc" rel="noreferrer" target="_blank">https://github.com/include-what-you-use/include-what-you-use/blob/master/iwyu_include_picker.cc</a>)<br>
<br>
Assuming you want this to be portable I'm sure you can do something<br>
similar in C++ relatively easily.<br>
<br>
FWIW,<br>
