Functions

afilter
auto afilter(T[] arr)
Undocumented in source. Be warned that the author may not have intended to support it.
amap
auto amap(T[] arr)
Undocumented in source. Be warned that the author may not have intended to support it.
asort
auto asort(T[] arr)
Undocumented in source. Be warned that the author may not have intended to support it.
auniq
auto auniq(T[] arr)
Undocumented in source. Be warned that the author may not have intended to support it.
contains
bool contains(T[] arr, V val)

Whether array contains value, no BS.

containsAt
bool containsAt(T[] haystack, T[] needle, size_t offset)

Like startsWith, but with an offset.

countSort
T[] countSort(T[] arr)
Undocumented in source. Be warned that the author may not have intended to support it.
eat
deprecated bool eat(T[] arr, T[] prefix)

If arr starts with prefix, slice it off and return true. Otherwise leave arr unchaned and return false.

emptySlice
auto emptySlice()

Returns an empty, but non-null slice of T.

fromBytes
inout(T) fromBytes(inout(ubyte)[] bytes)

Reverse of bytes()

get
T get(T[] arr, size_t index)

Like AA.get - soft indexing, throws an Exception (not an Error) on out-of-bounds, even in release builds.

get
auto get(T[] arr, size_t index, T defaultValue)

Like AA.get - soft indexing, returns default value on out-of-bounds.

getExpand
T getExpand(T[] arr, size_t index)

Expand the array if index is out-of-bounds.

indexOf
sizediff_t indexOf(T[] arr, D val)

Complement to std.string.indexOf which works with arrays of non-character types. Unlike std.algorithm.countUntil, it does not auto-decode, and returns an index usable for array indexing/slicing.

indexOf
sizediff_t indexOf(T[] arr, T[] val)
Undocumented in source. Be warned that the author may not have intended to support it.
indexOfElement
sizediff_t indexOfElement(T[] arr, D val)

Index of element, no BS.

isIn
bool isIn(T val, T[] arr)
Undocumented in source. Be warned that the author may not have intended to support it.
isOneOf
bool isOneOf(T val, T[] arr)
Undocumented in source. Be warned that the author may not have intended to support it.
list
auto list(Args args)

Equivalent of PHP's list language construct: http://php.net/manual/en/function.list.php

Works with arrays and tuples. Specify null as an argument to ignore that index (equivalent of list(x, , y) in PHP).

memcmp
int memcmp(ubyte[] a, ubyte[] b)
Undocumented in source. Be warned that the author may not have intended to support it.
memmove
void memmove(T[] dst, T[] src)

Like std.algorithm.copy, but without the auto-decode bullshit. https://issues.dlang.org/show_bug.cgi?id=13650

padRight
T[] padRight(T[] s, size_t l, T c)
Undocumented in source. Be warned that the author may not have intended to support it.
pluck
T pluck(T[] arr)

Select and return a random element from the array, and remove it from the array.

putExpand
T putExpand(T[] arr, size_t index, T value)

Expand the array if index is out-of-bounds.

queuePeek
T queuePeek(T[] arr)
Undocumented in source. Be warned that the author may not have intended to support it.
queuePeekLast
T queuePeekLast(T[] arr)
Undocumented in source. Be warned that the author may not have intended to support it.
queuePop
T queuePop(T[] arr)
Undocumented in source. Be warned that the author may not have intended to support it.
repeatOne
T[] repeatOne(T c, size_t l)
Undocumented in source. Be warned that the author may not have intended to support it.
sample
auto ref sample(T[] arr)

Select and return a random element from the array.

shift
T shift(T[] arr)
Undocumented in source. Be warned that the author may not have intended to support it.
shift
T[] shift(T[] arr, size_t n)
Undocumented in source. Be warned that the author may not have intended to support it.
shift
T[N] shift(T[] arr)
Undocumented in source. Be warned that the author may not have intended to support it.
skipUntil
T[] skipUntil(T[] source, D delim, bool orUntilEnd)

Returns the slice of source up to the first occurrence of delim, and fast-forwards source to the point after delim. If delim is not found, the behavior depends on orUntilEnd: - If orUntilEnd is false (default), it returns null and leaves source unchanged. - If orUntilEnd is true, it returns source, and then sets source to null.

slice
T[] slice(T[] arr, size_t p0, size_t p1)

Slices an array. Throws an Exception (not an Error) on out-of-bounds, even in release builds.

sliceIndex
size_t sliceIndex(T[] arr, T[] slice)

Given an array and its slice, returns the start index of the slice inside the array.

splitEmpty
auto splitEmpty(T value, S separator)

Like std.array.split, but returns null if val was empty.

stackPeek
T stackPeek(T[] arr)
Undocumented in source. Be warned that the author may not have intended to support it.
stackPop
T stackPop(T[] arr)
Undocumented in source. Be warned that the author may not have intended to support it.
stackPush
void stackPush(T[] arr, T val)
Undocumented in source. Be warned that the author may not have intended to support it.
toArray
T[] toArray(T v)

Slice a variable.

unshift
void unshift(T[] arr, T value)
Undocumented in source. Be warned that the author may not have intended to support it.
unshift
void unshift(T[] arr, T[] value)
Undocumented in source. Be warned that the author may not have intended to support it.

T[] vectorAssign(T[] a, T[] b)
Undocumented in source. Be warned that the author may not have intended to support it.
