[Ctags] regex question

[Johannes Z. <joh...@ze...>]

Hi,

the following pattern:

--langdef=basic
--langmap=basic:.bas.vbs.sba
--regex-basic=/^[ \t]*(private[ \t]+)?(sub|function)[ \t]+([^( \t]+)/\3/r,regex/ei

yiels with a *.sba file containing

Sub Main

a tag file like this (note that there are tag entries ABOVE THE HEADER)

	Macro1.sba	/^Sub Main$/;"	r
	Macro2.bas	/^Sub Main$/;"	r
	PolyMAXpci01.sba	/^Sub Main$/;"	r
	syn.sba	/^Sub Main$/;"	r
!_TAG_FILE_FORMAT	2	/extended format; --format=1 will not append ;" to lines/
!_TAG_FILE_SORTED	1	/0=unsorted, 1=sorted/
!_TAG_PROGRAM_AUTHOR	Darren Hiebert	/da...@hi.../
!_TAG_PROGRAM_NAME	Exuberant Ctags	//
!_TAG_PROGRAM_URL	http://ctags.sourceforge.net	/official site/
!_TAG_PROGRAM_VERSION	5.0.1	//
DialogProc	Macro1.sba	/^Private Function DialogProc(DlgItem$, Action%, SuppValue%) As Boolean$/;"	r
DialogProc	syn.sba	/^Private Function DialogProc(DlgItem$, Action%, SuppValue%) As Boolean$/;"	r
Dialog_XDIO40	X-DIO-40.sba	/^Private Sub Dialog_XDIO40 ' [-- SETTING UP THE DIALOG --]$/;"	r
Main	X-DIO-40.sba	/^Sub Main $/;"	r
Main


If I add a space after 'Sub Main ' everything's ok.
Apparently the regex replacement \3 evaluates to an empty string.
Is this a bug ?
