Seq stands for a-z or 0-9 which can be used only in Include and Exclude. When you write Include(Seq('a', 'm')) it means you are including a character from that sequence in a given position of your pattern. So if you have
Pattern(Include(Seq('a', 'm')), 'c')
That is sort of building the following set of strings.
ac
bc
cc
.
.
.
When you use Exclude, it would be like you are picking a char that is not belonging to the sequence, like in:
Pattern(Exclude(Seq('0, 9')), c)
then you would end up with a set like:
ac
bc
cc
.
.
.
It means, a set whose first character of the elements arent digits.
- masklinn 9y agoSeq is odd, to me Seq('a', 'm') says it matches 'am'. Why not overload X to support filtered forms instead? E.g X() is ".", X(from_, to_) is $from-$to, X(items) is [$items] and X(exclude) is [^$items]?
- iogf 9y agohmm, I think it is good, maybe p0 = X('a', 'z'). I like it.
- masklinn 9y agoPlus then you get to more add convenient overloads e.g. (X('a') | X('z')), (~X('q')), X[1:7] (I guess slices would be ranges, and indexes would be explicit numbers of repetitions), etc…
- iogf 9y agoI think so i would ask you to open issues in crocs at github, so i can better keep track of suggestions and implement them.
