API

ASCII_RANGE is an array with two indices: [bottomOfRange, topOfRange]

Chars.ASCII_RANGE_UPPERCASE Chars.ASCII_RANGE_LOWERCASE Chars.ASCII_RANGE_NUMBERS Chars.ASCII_RANGE_SPECIAL_1 Chars.ASCII_RANGE_SPECIAL_2 Chars.ASCII_RANGE_SPECIAL_3 Chars.ASCII_RANGE_SPECIAL_4 Chars.ASCII_RANGE_ALL

Chars.REGEXP_SPECIAL_CHARS

<array> REGEXP_SPECIAL_CHARS

Returns an array (like a set) with all special characters used in regular expressions.

Chars.ascii Chars.ordinal

Chars.isUpper

<boolean> Chars.isUpper( <string>/<number> char )

Returns true if char is uppercase.

Chars.isLower

<boolean> Chars.isLower( <string>/<number> char )

Returns true if char is lowercase.

Chars.isAlpha

<boolean> Chars.isAlpha( <string>/<number> char )

Returns true if char is uppercase or lowercase alpha.

Chars.isNumeric

<boolean> Chars.isNumeric( <string>/<number> char )

Returns true if char is a number.

Chars.isSpecial

<boolean> Chars.isSpecial( <string>/<number> char )

Returns true if char is a special character from the SPECIAL_1,2,3 or 4 range.

Chars.isAlphaNumeric

<boolean> Chars.isAlphaNumeric( <string>/<number> char )

Returns true if char is a uppercase, lowercase or number.

Chars.random

<string> Chars.random( range )

Returns a random character in range range. range defaults to the Chars.ASCII_RANGE_ALL range

Chars.prototype.constructor

<object> constructor( <string>/<number> char, <array> range )

char can be a number character or ordinal, range has the format of ASCII_RANGE

Chars.prototype.get

<string> get()

Returns this.char

Chars.prototype.set

Proceed this.char to the following ascii character, if no arguments are given. Proceed to amount ascii characters ahead, limited by this.range, if amount is set.

Chars.prototype.prev

<this> prev( <string>/<number> amount )

Proceed this.char to the following ascii character, if no arguments are given. Proceed to amount ascii characters back, limited by this.range, if amount is set.
