Classes
struct	FileOffset
	Error context for a failed parse, such as the error reason, line, and character offset. More...
class	IntegerParser
	Parser for positive integers, either decimal or hexadecimal. More...
class	LengthParser
	Parser for CSS <length-percentage> strings, such as "10px", "30%", "10em", etc. More...
class	LengthParserImpl
	Implementation of the LengthParser. More...
class	LineOffsets
	Helper class for finding newlines in a string, so that error messages can convert string-relative offsets into line numbers. More...
class	NumberParser

struct	ParseError
	Error context for a failed parse, such as the error reason, line, and character offset. More...
class	ParserBase
	Base class for parsers, containing common functionality such as maintaining the current parse location, skipping whitespace, and parsing numbers. More...
class	ParseResult
	A parser result, which may contain a result of type T, or an error, or both. More...

Functions
std::ostream &	operator<< (std::ostream &os, const ParseError &error)
	Ostream output operator for ParseError, outputs the error message.
template<typename T >
void	PrintTo (const ParseResult< T > &result, std::ostream *os)
	Outputs a ParseResult to a stream for debugging purposes.
	MATCHER (NoParseError, "")
	Matches if the result does not contain a ParseError.
	MATCHER_P (ParseErrorIs, errorMessageMatcher, "")
	Given a ParseResult, matches if it contains an error with the given message.
	MATCHER_P2 (ParseErrorPos, lineMatcher, offsetMatcher, "")
	Given a ParseResult, matches if it contains an error at the given offset.
	MATCHER (ParseErrorEndOfString, "")
	Matches if a ParseResult contains an error at the end of the string.
	MATCHER_P (ParseResultIs, resultMatcher, "")
	Matches if a ParseResult contains a result that matches the given value, and that it does not contain an error.
	MATCHER_P2 (ParseResultAndError, resultMatcher, errorMessageMatcher, "")
	Matches if a ParseResult contains a result that matches the given value, and that it does not contain an error.

Parameters

errorMessageMatcher

Message to match with, either a string or a gmock matcher.

MATCHER_P() [2/2]

donner::base::parser::MATCHER_P	(	ParseResultIs	,
		resultMatcher	,
		""	)

Matches if a ParseResult contains a result that matches the given value, and that it does not contain an error.

Parameters

resultMatcher

Value to match with.

MATCHER_P2() [1/2]

donner::base::parser::MATCHER_P2	(	ParseErrorPos	,
		lineMatcher	,
		offsetMatcher	,
		""	)

Given a ParseResult, matches if it contains an error at the given offset.

Parameters

lineMatcher	Line number of the error.
offsetMatcher	Column offset of the error.

MATCHER_P2() [2/2]

donner::base::parser::MATCHER_P2	(	ParseResultAndError	,
		resultMatcher	,
		errorMessageMatcher	,
		""	)

Matches if a ParseResult contains a result that matches the given value, and that it does not contain an error.

Parameters
