Hi, With v1.96.0 of Parse::RecDescent and Text::Balanced v2.0.0 the following grammar is not parsed as I would expect: A: ( x x ) ( x x ) This results in 'Untranslatable item encountered: ")"'. This appears to be a logic error in the code around line 1920 starting with ... elsif ($grammar =~ m/(?=$IMPLICITSUBRULE)/gco and do { ($code) = extract_codeblock($grammar,'{([',undef,'(',1); $code }) { $code =~ s/\A\s*\(|\)\Z//g; ... Here $code is '( x x ) ( x x )' and is then turned into 'x x ) ( x x'. I am somewhat unsure from the documentation of Text::Balanced whether it is supposed to return '( x x ) ( x x )' rather than '( x x )', it may be a good idea to document that one way or the other. (By the way, the code passes five parameters to extract_codeblock while it only seems to document four parameters, but then uses them all.) regards, -- Björn Höhrmann · mailto:bjoern@hoehrmann.de · http://bjoern.hoehrmann.de Am Badedeich 7 · Telefon: +49(0)160/4415681 · http://www.bjoernsworld.de 25899 Dagebüll · PGP Pub.
