Question

In Doxygen, to get the copyright symbol in HTML output, the documentation must use ©, as in:

/// @copyright Copyright © 2012

In this case, I’d prefer to type it like this:

/// @copyright Copyright (c) 2012

In the latter example, it looks a little nicer and would probably translate over to plain text & RTF output better as well. Is it possible to create a text to entity mapping in Doxygen? For example, (c) would map to ©, and doxygen would simply replace all (c) occurrences with ©

Answer 1

In general I think such substitutions are better handled by an input filter.
Here is a simple filter that would replace a (c) followed by some digits by © and then the same digits:

#!/bin/perl
open(F,"<$ARGV[0]") || die("Failed to open file $ARGV[0]: $!");
while (<F>)
{
  s/\([cC]\)(\s*\d+)/&copy;\1/g;
  print $_;
}
close(F);

To use this filter put the following in the config file:

INPUT_FILTER = "perl filter.pl"

Note 1 The filter will process the whole file. It might be a useful feature to allow a filter that is only applied to comments.

Note 2 If you use a UTF-8 capable editor and corresponding encoding (INPUT_ENCODING) you can also insert the copyright character directly (code C2 A9 hex)
