I have a situation with the following grammar:
my $parse = Parse::RecDescent->new(<<'EndGrammar');
rebol : block { dump_item('block', \@item) }
| scalar { dump_item('scalar', \@item) }
block : '[' block_stuff(s?) ']'
block_stuff : scalar
scalar : <skip:''> '%' file
file : /w+/
EndGrammar
My grammar matches a filename, ie:
%reb.html
just fine. However, it does not match a filename within a block, ie:
[ %reb.html ]
and I know exactly why after tracing the grammar.
It is trying the
<skip:''> '%' file
production with the input text
" %reb.html"
note the space in the input text.
The reason this distresses me is that I have not changed the universal token separator from
/\s*/
Yet it did not gobble up the white space between the
'[' terminal and the
<skip:''>'%' file production
