Expand description

Errors and warnings that can occur during string unescaping.

Variants§

§

LoneSlash

Escaped ’' character without continuation.

§

InvalidEscape

Invalid escape character (e.g. ‘\z’).

§

BareCarriageReturn

Raw ‘\r’ encountered.

§

CannotSkipMultipleLines

Can only skip one line of whitespace.

"this is \
 ok" == "this is ok";

"this is \
 \
 also ok" == "this is also ok";

"this is \
  
 not ok"; // error: cannot skip multiple lines
§

HexEscapeTooShort

Numeric character escape is too short (e.g. ‘\x1’).

§

InvalidHexEscape

Invalid character in numeric escape (e.g. ‘\xz1’).

§

UnicodeEscapeTooShort

Unicode character escape is too short (e.g. ‘\u1’).

§

InvalidUnicodeEscape

Invalid character in unicode character escape (e.g. ‘\uz111’).

§

StrNewline

Newline in string literal. These must be escaped.

§

StrNonAsciiChar

Non-ASCII character in non-unicode literal.

§

HexNotHexDigit

Non hex-digit character in hex literal.

§

HexBadUnderscore

Underscore in hex literal.

§

HexOddDigits

Odd number of hex digits in hex literal.

§

HexPrefix

Hex literal with the 0x prefix.
