Detailed Description

Simple matcher expression parser.

The parser understands matcher expressions of the form: MatcherName(Arg0, Arg1, ..., ArgN) as well as simple types like strings. The parser does not know how to process the matchers. It delegates this task to a Sema object received as an argument.

Grammar for the expressions supported:
<Expression>        := <Literal> | <NamedValue> | <MatcherExpression>
<Literal>           := <StringLiteral> | <Boolean> | <Double> | <Unsigned>
<StringLiteral>     := "quoted string"
<Boolean>           := true | false
<Double>            := [0-9]+.[0-9]* | [0-9]+.[0-9]*[eE][-+]?[0-9]+
<Unsigned>          := [0-9]+
<NamedValue>        := <Identifier>
<MatcherExpression> := <Identifier>(<ArgumentList>) |
                       <Identifier>(<ArgumentList>).bind(<StringLiteral>)
<Identifier>        := [a-zA-Z]+
<ArgumentList>      := <Expression> | <Expression>,<ArgumentList>
