Methods

=~(x:Any, nr:NumRange, _mc:MatchContext) Source: stdlib.ngs:2704

Checks whether x is in the range.

Example

1 =~ 0..5  # true

[](arr:Arr, range:NumRange)

Get array elements at specified indexes.

Returns

Arr

[](s:Str, range:NumRange)

Get substring

Example

"abcd"[1..3]  # "bc"

[](arr:Arr, r:NumRange) Source: stdlib.ngs:3347

Get array elements at specified indexes. Indexes specified by NumRange.

Parameters

r	NumRange with negative .end

Returns

Arr

Example

[10,20,30,40][1..-1]  # [20,30]

[](s:Str, r:NumRange) Source: stdlib.ngs:4820

Get a substring. Indexes in s are specified by NumRange.

Parameters

s	Original string
r	NumRange with negatve .end

Returns

Str

Example

"(Look ma, no parens)"[1..-1]  # "Look ma, no parens"

[]=(arr:Arr, range:NumRange, replacement:Arr)

Set array elements at specified indexes.

Returns

replacement

[]=(s:Str, range:NumRange, replacement:Str)

Change substring

Returns

replacement

Example

s="abcd"; s[1..3]="X"; s  # "aXd"

each(r:NumRange, cb:Fun) Source: stdlib.ngs:2659

Iterates over the elements of r, passing each in turn to cb.

Parameters

cb	Function to be called with values from r

Returns

r

Example

s=0
(1...10).each(F(i) { global s; s+=i })
echo(s)  # Outputs: 55

ensure(n:Int, r:NumRange) Source: stdlib.ngs:2715

Checks that x is in the range.

Example

ensure(3, 3..10)  # 3

finished_ok(p:Process, field_name:Str, ok:NumRange)internal Source: stdlib.ngs:6377

Decide whether a process finished normally.

Example

$(ok:0..10 ls no-such-file)

in(n:Int, r:NumRange) Source: stdlib.ngs:2670

Check whether the number is in range 10 in 10..20 # true 1 in 10..20 # false

init(r:Repeat, pattern:Any, count:NumRange) Source: stdlib.ngs:1299

Undocumented

init(i:RangeIter, r:NumRange)

Initialize RangeIter. Will throw NotImplemented if r.start or r.step are not Int

Iter(r:NumRange)

Create Iter from NumRange

len(r:NumRange) Source: stdlib.ngs:2693

Length of a NumRange. Only defined for Int start and end. Equals to how many times cb will be invoked in each(r, cb).

rand(r:NumRange) Source: stdlib.ngs:8343

Pick one random element from a range

Returns

Any
