CompilerKit::Error

Compiler errors in CompilerKit are all represented by the Error class. New instances of error cannot be created through the constructor. Instead, static functions are provided to create different types of errors.

Errors can be printed to any standard library output stream (#include <iostream>) using the standard caret syntax:

Error err = Error:Generic("I/O", "something went wrong", token);
std::cout << err << "\n";

Static API

Error::Syntax(const string& expected, const Token& token) -> Error

Returns a new instance of Error for a syntax error, for a given expected token type and actual found token.

Parameters:

• expected: the type of token that was expected by the parser.
• token: the token that was found by the parser.

Error::Semantic(const string& message, const Token& token) -> Error

Returns a new instance of Error for a semantic error at a given token in the source code.

Parameters:

• message: the error message to attach to the error.
• token: the token where the error was found.

Error::Generic(const string& type, const string& message, const Token& token) -> Error

Returns a compiler error of a given type, at a given token and with a given message.

Parameters:

• type: a type of error, shown when printing the error.
• message: the error message to attach to the error.
• token: the token where the error was found.

Public API

print(std::ostream& out) -> void

Prints the error, along with its source code location, to an output stream.

Parameters:

• out: the output stream to print this to.

Operators

operator<(const Error& other) const -> bool
operator>(const Error& other) const -> bool

Comparison operators implemented to allow sorting a collection of errors by line and columns.
