使用ruby的treetop peg来解析debian Packages.gz
我正在尝试使用Ruby的树梢打开一个Packages.gz，但我无法明确地使用关键字和值。这是我的树梢语法：
grammar Debian
rule collection
entry+
end
rule entry
(tag space value)
end
rule package_details
tag value &[^$]
end
rule tag
[A-Za-z0-9-]+ ":"
end
rule value
(!tag value_line+ "n")+
end
rule value_line
([A-Za-z0-9 <>@()=.-|/,_"':])+
end
rule space
[ t]+
end
end

grammar Debian # The file is too big for us to emit a package_list.
