FreeC.Frontend.IR.Scanner
Description
This module contains a scanner for the intermediate language that takes the source code and converts it into a token stream.
We convert the source code to a token stream such that FreeC.Frontend.IR.Parser does not have to handle whitespace explicitly.
Synopsis
- data TokenWithPos = TokenWithPos {}
- scan :: MonadReporter r => SrcFile -> r [TokenWithPos]
Documentation
data TokenWithPos Source #
A Token and its position in the source code.
Constructors
| TokenWithPos | |
Fields
| |
Instances
| Show TokenWithPos Source # | We need a show instance for tokens with positions such that the parser can print unexpected tokens. |
Defined in FreeC.Frontend.IR.Scanner | |
scan :: MonadReporter r => SrcFile -> r [TokenWithPos] Source #
Converts the given IR source code to a stream of IR tokens.
Reports a fatal error if there are unknown tokens.
