I was hoping somebody else would reply as I have limited knowledge about
this feature.
I've installed the 'source-highlight' program and tested this with
texi2any 7.2. (Building from the git repository has been broken for a
few days.) It appears to work fine, both with and without --no-split.
Highlighting appears in the output file. Can you produce a minimum
failing example?
$ cat src-hl.texi
\input texinfo
@node Top
@top
@example C
#include <stdio.h>
int
main (void)
@{
printf ("Hello world!\n");
@}
@end example
@example C
@include src-hl.c
@end example
@bye
$ cat src-hl.c
#include <stdio.h>
int
main (void)
@{
printf ("Hello world!\n");
@}
$ texi2any --html src-hl.texi -c HIGHLIGHT_SYNTAX='source-highlight'
src-hl.texi: warning: must specify a title with a title command or @top
$ texi2any --html src-hl.texi -c HIGHLIGHT_SYNTAX='source-highlight' --no-split
src-hl.texi: warning: must specify a title with a title command or @top
$
