Public Methods
const Err & err ()The result of parsing. Since this does not have access to the initial string, it will not
indicate context for the error. That can be generated from the error_token() if desired.

ExprToken error_token ()Defined at line 64 of file ../../src/developer/debug/zxdb/expr/expr_parser.h
void ExprParser (std::vector<ExprToken> tokens, ExprLanguage lang, fxl::RefPtr<EvalContext> eval_context)The eval context can be null if the caller doesn't have any symbol context. This means that we
can't resolve any type or variable names, and can't disambiguate some cases like how to parse
"Foo < 1 > bar". In this mode, we'll assume that "<" after a name always mean a template rather
than a comparison operation.

fxl::RefPtr<ExprNode> ParseStandaloneExpression ()Parses an expression by itself, for example, the content of the debugger frontend "print"
command. This should never be called internally by the parser to parse subexpressions, use
ParseExpression() for that.
Returns the root expression node on successful parsing. On error, returns an empty pointer in
which case the error message can be read from err() and error_token()

fxl::RefPtr<BlockExprNode> ParseBlock (BlockDelimiter delimiter)Parses a block. { and } will be consumed (these are optional if the block delimiter is set to
implicit). The input is counted as being complete.

Err ParseIdentifier (const std::string & input, Identifier * output)Attempts to parse the given string as an identifier. The returned err indicates whether the
output identifier is valid.
