Usage

toArray

Converts a string to an array

string.toArray("a", "|") => ["a"]
string.toArray("", "|") => []

pad

Pads a string

//pad at the end
string.pad("STR", 5, " ", true) => "STR  "

//pad at the beginning
string.pad("STR", 5, "$") => "$$STR"

truncate

Truncates a string to the specified length.

//from the beginning
string.truncate("abcdefg", 3) => "abc";
//from the end
string.truncate("abcdefg", 3,true) => "efg"
//omit the length
string.truncate("abcdefg") => "abcdefg"

multiply

Returns a string duplicated n times

string.multiply("HELLO", 5) => "HELLOHELLOHELLOHELLOHELLO"

escape

Escapes a string so that it can safely be used in a RegExp.

stringExtended.escape(".$?*|{}()[]\/+^"); "//\.\$\?\*\|\{\}\(\)\[\]\/\+\^"

stringExtended(".$?*|{}()[]\/+^").escape().value(); "//\.\$\?\*\|\{\}\(\)\[\]\/\+\^"

You can also specify an optional array of characters to ignore when escaping.

stringExtended.escape(".$?*|{}()[]\/+^", [".", "?", "{", "["]); //".\$?\*\|{\}\(\)[\]\/\+\^"
stringExtended(".$?*|{}()[]\/+^").escape([".", "?", "{", "["]).value(); //".\$?\*\|{\}\(\)[\]\/\+\^"

trim Trims white space characters from the beginning and end of a string.

stringExtended.trim("   Hello World   "); //"Hello World"

stringExtended("   Hello World   ").trim().value(); //"Hello World"

trimLeft

Trims white space characters from the beginning of a string.

stringExtended.trimLeft("   Hello World   "); //"Hello World   "

stringExtended("   Hello World   ").trimLeft().value(); //"Hello World   "

trimRight

Trims white space characters from the end of a string.

stringExtended.trimLeft("   Hello World   "); //"   Hello World"

stringExtended("   Hello World   ").trimLeft().value(); //"   Hello World"

format

Formats a string with the specified format.

1. String Formats %[options]s

   • • : left justified
   • Char : padding character Excludes d,j,s
   • Number : width

2. Number Formats %[options]d

   • • : left justified
   • • : signed number
   • Char : padding character Excludes d,j,s
   • Number : width

3. Object Formats %[options]j

   • Number : spacing for object properties.

var format = string.format;

format("%s, %s", ["Hello", "World"]) => "Hello, World";

format("%[ 10]s, %[- 10]s", ["Hello", "World"]); //"     Hello, World     ";

format("%-!10s, %#10s, %10s and %-10s", "apple", "orange", "bananas", "watermelons")
     //"apple!!!!!, ####orange,    bananas and watermelon"

format("%+d, %+d, %10d, %-10d, %-+#10d, %10d", 1,-2, 1, 2, 3, 100000000000)
     //"+1, -2, 0000000001, 2000000000, +3########, 1000000000"

format("%[h:mm a]D", [date]) => 7:32 PM - local -

format("%[h:mm a]Z", [date]) => 12:32 PM - UTC

 //When using object formats they must be in an array otherwise
 //format will try to interpolate the properties into the string.
format("%j", [{a : "b"}]); //'{"a":"b"}'

format("%1j, %4j", [{a : "b"}, {a : "b"}]); //'{\n "a": "b"\n},\n{\n    "a": "b"\n}'

format("{hello}, {world}", {hello : "Hello", world : "World"); //"Hello, World";

format({[-s10]apple}, {[%#10]orange}, {[10]banana} and {[-10]watermelons}",{
    apple : "apple",
    orange : "orange",
    banana : "bananas",
    watermelons : "watermelons"
}); //"applesssss, ####orange,    bananas and watermelon"
