Methods

limit(a:Arr, l:Int) Source: stdlib.ngs:2008

Truncate an array if necessary so it would have maximum l elements.

Parameters

a	Array to (possibly) truncate.
l	Maximum elements

Returns

Either a or new Arr of length l

Example

[10,11,12].limit(2)   # [10,11]
[10,11,12].limit(10)  # [10,11,12]

limit(h:Hash, l:Int) Source: stdlib.ngs:2584

Truncate a Hash if necessary so it would have maximum l key-value pairs.

Parameters

h	Source hash
l	Maximum elements

Returns

Hash

Example

{"a": 1, "b": 2}.limit(1)  # {"a": 1}

limit(s:Str, n:Int, marker:Str='') Source: stdlib.ngs:3483

Truncate a string if necessary so it would have maximum n characters (currently bytes).

Parameters

s	The string to (possibly) truncate.
n	Maximum characters
marker	The truncation marker

Returns

Either s or new Str of length n

Example

"abc".limit(5, "...")     # "abc"
"abcdef".limit(5, "...")  # "ab..."
"abcdef".limit(2)         # "ab"
