it would be nice if the - (string) node would support similar characterdefinitions as in regexpr. at the moment, you have to create a “- (String)” node manually
for each string you want to subtract.
for example take this spread:
abcd23
xyz12
34qwertz
i like to subtract all numbers of each index…
it would be nice to feed the operand2 inlet with something like /d.
or maybe theres a clever node combination (with regexpr ad string spectral etc…)
of which i have no clue???
i think RegExpr should be able to do this trick. I have added some text to FAQ RegExpr The main question is how to deal with malformed inputs - can they occur, should they generate additional slices, should they be ignored etc…
hmm, my description of the problem in my previous post was really unclear.
regexpr acts as a filter which just let pass strings that mach the definition. and it creates a new silceindex for every match. im looking for a way to subtract strings without affecting the slicecount.
if, for example, an index contains a string which doesnt match, the outputspread of regexpr has a different slicecount. while “- string” has no affect to the slicecount.
heres a better example:
abcd23,
xyz12,
1223,
34qwertz (Slicecount 4)
|
|
v
regexpr with (\D*)
|
|
v
abcd23,
xyz12,
34qwertz (Slicecount 3)
a “- (String)”-node which would accept for example /d* as operand2, could solve the problem.
yes. thats why i said, the main question is how to deal with malformed inputs… what do you want to get from (abcd23, xyz12, 1223, 34qwertz) ??
(abcd, xyz, , qwertz) ??
i think the start of line and end of line tokens $ ^ will help you. of maybe prefixing all strings with a separate token…
i actually already logged a feature request for a pin at the regexpr node, which would return the orginating slice index of a given output slice. but this will not make it into the next release (which will be released REAL SOON NOW)
