Hi,
I am trying to make a regex that matches a term with an arbitrary number of arguments. It has the format:
TERM KEY(-?PRE:COL[,-?PRE:COL]*)
with at least 1 PRE:COL and at most N (comma separated) PRE:COL, each of them possible prefixe with 1 '-' char
I have the following:
^([[:word:]])[[:blank:]]*KEY\\(-?[[:word:]]+:[[:word:]]+(,-?([[:word:]])+:([[:word:]]+))*\\)
But this does not work: e.g. the string
KEY1 KEY(TEK:KDE),NOCASE,OPT,PRIMARY
has the following matches (notice the empty matches):
what[0] = KEY1 KEY(TEK:KDE),NOCASE,OPT,PRIMARY what[1] = KEY1 what[2] = TEK what[3] = KDE what[4] = what[5] = what[6] =
and the string
KEY1 KEY(RKM:KEN,RKM:REL,RKM:VAL),NOCASE,OPT,PRIMARY
has the following matches (notice match 4 and the lack of the last PRE:COL pair):
auxWhat[0] = KEY1 KEY(RKM:KEN,RKM:REL,RKM:VAL),NOCASE,OPT,PRIMARY auxWhat[1] = KEY1 auxWhat[2] = RKM auxWhat[3] = KEN auxWhat[4] = ,RKM:VAL auxWhat[5] = RKM auxWhat[6] = VAL
Is there a regex that sort of does does what I want?
Slightly offtopic, sounds better suited to Boost.Spirit.Qi.
