[REBOL] [Feature request] FIND vs PARSE
From: Rebolinth::nodep::dds::nl at: 30-Jul-2003 15:45
Hello All / RT,
As there is no option inside PARSE function that returns the
parsed delimiters (only the result) doing a walkthru,
a FIND or PARSE enhancement might be usefull?
# First #
Basicly a migration of the PARSE actions to the FIND function.
(|) skip with thru to
The idea comes from the fact that PARSE does a complete walktrhu the
series while FIND stops at the point where it finds. This means that
find needs an extention with a loop function to behave like PARSE.
a: {.....endlessly long string......endlessly long string.....}
find a [ thru "endlessly" copy b to "string" ]
find a [ 3 "." ]
find a [ "." | "," ]
# second #
a new PARSE option: /inverse
a: {.....endlessly long string......endlessly long string.....}
>>parse/inverse a [ "long" ]
== [ "" "" "" "long" "" "" "" "long" "" "" ""]

Norman.
