Function std.array.split
Eagerly splits range
into an array, using sep
as the delimiter.
S[] split(S)
(
S s
) pure @safe
if (isSomeString!S);
auto split(Range, Separator)
(
Range range,
Separator sep
)
if (isForwardRange!Range && (is(typeof(ElementType!Range .init == Separator .init)) || is(typeof(ElementType!Range .init == ElementType!Separator .init)) && isForwardRange!Separator));
auto split(alias isTerminator, Range)
(
Range range
)
if (isForwardRange!Range && is(typeof(unaryFun!isTerminator(range .front))));
When no delimiter is provided, strings are split into an array of words, using whitespace as delimiter. Runs of whitespace are merged together (no empty words are produced).
The range
must be a forward range.
The separator can be a value of the same type as the elements in range
or it can be another forward range
.
Parameters
Name | Description |
---|---|
s | the string to split by word if no separator is given |
range | the range to split |
sep | a value of the same type as the elements of range or another |
isTerminator | a predicate that splits the range when it returns true . |
Returns
An array containing the divided parts of range
(or the words of s
).
See Also
splitter
for a lazy version without allocating memory.
splitter
for a version that splits using a regular
expression defined separator.
Example
import std .uni : isWhite;
writeln("Learning,D,is,fun" .split(",")); // ["Learning", "D", "is", "fun"]
writeln("Learning D is fun" .split!isWhite); // ["Learning", "D", "is", "fun"]
writeln("Learning D is fun" .split(" D ")); // ["Learning", "is fun"]
Example
string str = "Hello World!";
writeln(str .split); // ["Hello", "World!"]
string str2 = "Hello\t\tWorld\t!";
writeln(str2 .split); // ["Hello", "World", "!"]
Example
writeln(split("hello world")); // ["hello", "world"]
writeln(split("192.168.0.1", ".")); // ["192", "168", "0", "1"]
auto a = split([1, 2, 3, 4, 5, 1, 2, 3, 4, 5], [2, 3]);
writeln(a); // [[1], [4, 5, 1], [4, 5]]
