#45500: ctags 5.8_1 ignores --regex- flags

     Type:  defect     |     Status:  new
 Priority:  Normal     |  Milestone:
Component:  ports      |    Version:  2.3.2
 Keywords:             |       Port:  ctags
-----------------------+--------------------------------
 ctags can be extended for additional language features with the
 --regex-<lang> flag. These appear to be ignored in the macports version of
 ctags. I believe ctags is compiled with the correct flags (+regex), so I'm
 not sure why this is happening.

 As an example, I get this on a linux box:

 {{{
 [@linux]• cat test.js
 var x = {
   test = function(){
   }
 };
 [@linux]• ctags --options=NONE --regex-
 javascript='/(\w+)\s*=\s*function/\1/f,function/' test.js
 No options will be read from files or environment
 [@linux]• cat tags
 !_TAG_FILE_FORMAT       2       /extended format; --format=1 will not
 append ;" to lines/
 !_TAG_FILE_SORTED       1       /0=unsorted, 1=sorted, 2=foldcase/

 }}}

 Notice the "test   test.js  ..." line in the tags file. And this on my
 Mac:

 I don't believe the +internal-sort flag should impact this. I wonder if
 this has to do with the regex library that ctags is compiled with?

 Thanks
