All,
I have the following lines that I would like to parse in python using
pyparsing, but have some problems forming the grammar.
Line in file:
table <ALINK> const { 207.135.103.128/26, 207.135.112.64/29 }
table <INTRANET> persist { ! 10.200.2/24, 10.200/22 }
table <RFC_1918> const { 192.168/16, ! 172.24.1/29, 172.16/12, 169.254/16 }
table <DIALER> persist { 10.202/22 }
table <RAVPN> const { 10.206/22 }
table <KS> const { \
10.205.1/24, \
169.136.241.68, \
169.136.241.70, \
169.136.241.71, \
169.136.241.72, \
169.136.241.75, \
169.136.241.76, \
169.136.241.77, \
169.136.241.78, \
169.136.241.79, \
169.136.241.81, \
169.136.241.82, \
169.136.241.85 }
I have the following grammar defn.
tableName = Word(alphanums + "-" + "_")
leftClose = Suppress("<")
rightClose = Suppress(">")
key = Suppress("table")
tableType = Regex("persist|const")
ip4Address = OneOrMore(Word(nums + "."))
ip4Network = Group(ip4Address + Optional(Word("/") +
OneOrMore(Word(nums))))
temp = ZeroOrMore("\\" + "\n")
tableList = OneOrMore(Optional("\\") |
ip4Network | ip4Address | Suppress(",") | Literal("!"))
leftParen = Suppress("{")
rightParen = Suppress("}")
table = key + leftClose + tableName + rightClose + tableType + \
leftParen + tableList + rightParen
I cannot seem to match sixth line in the file above, i.e table name with
KS, how do I form the grammar for it, BTW, I still cannot seem to ignore
comments using table.ignore(Literal("#") + restOfLine), I get a parse error.
Any help appreciated.
Thanks
Prabhu
