Hello,
I'd like to make a little suggestion for phobos: enrich
findSplit* method family with the "needleless" predicate option.
Motivation:
Let's have a range of string tokens that - after cutting of the
initial brace - looks like this:
auto range = ["23", "42", "14.3", "-323", "}"]
Now I want to map all the numbers to the array:
auto array = range.findSplitBefore(x =>
!x.isNumeric).map(to!double).array;
As you can see, I do not need the second parameter of prediate,
as I am not comparing the subsequent haystack elements with any
needle - I check the condition on the haystack elements alone
instead. Unfortunately, It's not that simple, because I have only
this prototype:
auto findSplitBefore(alias pred, R1, R2)(R1 haystack, R2
needle) //[...]
That's why I need to add a dummy parameter to achieve what I want
to:
auto array = range.findSplitBefore(x =>
!x.isNumeric)([""]).map(to!double).array;
So I suggest adding this prototype as well for convenience:
auto findSplitBefore(alias pred, R)(R haystack) //[...]
