Constructor & Destructor Documentation

Parser::Parser ( std::string  source )

inlineexplicit

Calls parse to create all expressions found in the source code.

Parameters

source

The source file as a string of characters. interpreter

Member Function Documentation

void Parser::code_gen	(	llvm::Module *	M,
		llvm::IRBuilder<> &	B
	)

Generates the IR (Intermediate Representation) code to be executed by llvm.

Parameters

M	A pointer to the Brain's module.
B	A reference to the Brain's IR builder.

void Parser::debug_description

(

int

level

)

Prints debug information when Brain's compiler has the active flags: -v | -emit-ast.

Parameters

level

The width used to display the debug information (to mimic identation).

void Parser::parse ( std::vector< Expr * > &  exprs, int  level  )

protected

It parses the Brain code.

Parameters

exprs	The vector of expressions read by the constructor
level

Member Data Documentation

std::vector<Expr *> Parser::_exprs

protected

Store pointers of expressions to later call code_gen on each one of them.
