String Transformation

Functions for converting case, encoding, escaping, and type conversion.

Transformation

Function	Method Alias	Description
`LowerCase(s)`	`.ToLower` / `.LowerCase`	Converts to lowercase (Unicode).
`ASCIILowerCase(s)`	-	Converts to lowercase (ASCII only).
`UpperCase(s)`	`.ToUpper` / `.UpperCase`	Converts to uppercase (Unicode).
`ASCIIUpperCase(s)`	-	Converts to uppercase (ASCII only).
`Trim(s)`	`.Trim`	Removes whitespace from both ends.
`Trim(s, L, R)`	`.Trim(L, R)`	Removes `L` chars from left and `R` from right.
`TrimLeft(s) / TrimRight(s)`	`.TrimLeft / .TrimRight`	Removes whitespace from one end.
`PadLeft(s, len [, ch])`	`.PadLeft(len [, ch])`	Pads string to `len` with character `ch`.
`PadRight(s, len [, ch])`	`.PadRight(len [, ch])`	Pads string to `len` with character `ch`.
`StrReplace(s, old, new)`	`.Replace(old, new)`	Replaces all occurrences of `old` with `new`.
`ReverseString(s)`	`.Reverse`	Reverses the character order.
`DupeString(s, count)`	`.Dupe(count)`	Returns the string repeated `count` times.
`NormalizeString(s)`	`.Normalize`	Normalizes Unicode string (NFC default).
`StripAccents(s)`	`.StripAccents`	Removes diacritics (e.g. é -> e).

Conversion

Function	Method Alias	Description
`IntToHex(v, digits)`	`.ToHexString(digits)`	Integer to hexadecimal string.
`IntToBin(v, digits)`	`.ToBinaryString(digits)`	Integer to binary string.
`HexToInt(s)`	`.HexToInteger`	Hexadecimal string to integer.
`FloatToStr(f [, p])`	`.ToString`	Float to string (optional precision `p`).
`ByteSizeToStr(v)`	-	Converts a number of bytes into human-readable size (e.g. "1.5 MB").
`BoolToStr(b)`	`.ToString`	Boolean to "True" or "False".
`StrToBool(s)`	`.ToBoolean`	String to boolean.

Encoding and Escaping

Function	Method Alias	Description
`StrToHtml(s)`	`.ToHtml`	HTML entity encoding.
`StrToHtmlAttribute(s)`	`.ToHtmlAttribute`	HTML attribute encoding.
`StrToJSON(s)`	`.ToJSON`	Escapes string for JSON/JavaScript literal.
`StrToCSSText(s)`	`.ToCSSText`	Escapes string for CSS content.
`StrToXML(s)`	`.ToXML`	XML text encoding.
`QuotedStr(s [, quote])`	`.QuotedString`	Wraps string in quotes (default `'`).
`NormalizeString(s [, form])`	`.Normalize`	Unicode normalization (NFC, NFD, etc).
`StrIsASCII(s)`	`.IsASCII`	Returns True if all characters in the string are ASCII (0..127).

Advanced Transformations

// Specialized Trimming
var s := "[[[Hello]]]";
PrintLn('Trim(3, 3): ' + s.Trim(3, 3));

// Array Packing (on dynamic array)
var arr : array of String = ['A', '', 'B', ' ', 'C'];
var packed := arr.Pack();
PrintLn('Packed: ' + packed.Join(', '));

// Unicode Normalization
var accented := 'e'#$0301; // e + combining acute accent
PrintLn('Length pre-normalize: ' + accented.Length.ToString);
var normalized := accented.Normalize();
PrintLn('Length post-normalize: ' + normalized.Length.ToString);

Result

Trim(3, 3): Hello
Packed: A, B,  , C
Length pre-normalize: 2
Length post-normalize: 1
