class EscapeSequence¶

extends:	`Object`

static method getCharacter(sequence: String, chr: Char *) → Int¶: This is a function for decoding an escape sequence. It supports the most common escape sequences and also hexadecimal (x0a) and octal (101) escape sequences. You have to pass the escape sequence without the leading backslash as sequence and a pointer to the result char as chr. The return value is one of EscapeSequence valid (chr contains a valid value now), EscapeSequence needMore (chr‘s content is undefined, the escape sequence is incomplete (the case for “x1”) and EscapeSequence invalid (like for “u”).

static method unescape(s: String) → String¶: Unescape the string s. This will handle hexadecimal, octal and one-character escape escape sequences. Unknown escape sequences will just get the ‘\’ stripped. (“\u” -> “u”)

static method escape(s: String) → String¶: Escape a string. This will replace non-printable characters with equivalents like something or x??.
