[Grammatica-users] regular expression problem in tokens

[Wieger Wesselink]

Hi,

when I put the regular expression '\d+(-\d+)+' in a token I would
expect that the string '1-23' is accepted. However, I get the following
error:

Parse tree from 1.pdn:
Error: in 1.pdn: line 1:
      unexpected character '1'

1-23
^

I have verified on http://www.fileformat.info/tool/regex.htm that
the string '1-23' matches with '\d+(-\d+)+'.

Is this a bug in Grammatica, or am I doing something wrong? For the
full grammar see below.

Best regards,

Wieger
