This will capture everything after the key/value pairs to the end of the line into a "message" entry:

Hi! I'm trying to write a lpeg grammar for parsing key-value tuples with a "suffix message". I got the key-value part working, but I can't figure out how to extract the rest of the message. My input data looks like this: x="a string" status=200 hello world I want to parse this into: message: "hello world" x: "a string" status: 200 The grammar currently looks like this (http://lpeg.trink.com/share/17121232195128835076): local l = require 'lpeg' l.locale(l) local sp = l.space local key = l.C((1 - l.S('= '))^1) local rawString = l.C((1 - sp)^1) local quotedString = l.C((l.P('\\"') + (1 - l.P('"')))^0) local integer = l.digit^1 / tonumber local double = l.digit^1 * "." * l.digit^1 / tonumber local pair = ( l.Cg(key * "=" * '"' * quotedString * '"' ) + l.Cg(key * "=" * (double + integer + rawString)) ) * sp^0 grammar = l.Cf(l.Ct("") * pair^0, rawset) I don't understand how to extract "hello world" into the result table. Any pointers on how to do this? Thanks, Anton _______________________________________________ Heka mailing list [email protected] https://mail.mozilla.org/listinfo/heka
