Detailed Description

template<typename Lexer>
struct Lex::ParseInput< Lexer >

Lexer functor for defining tokenization rules using Boost Spirit Lex.

This struct is a functor that defines the tokenization rules for the lexer. It inherits from boost::spirit::lex::lexer<Lexer> and is used to configure the lexer with regular expressions and corresponding token IDs. The rules are added to the lexer during construction.

Template Parameters

Lexer

The type of lexer to be used (e.g., boost::spirit::lex::lexertl::lexer<>).

The constructor performs the following steps:

1. Iterates over the token types defined in symbol_table::token_types_r_.
2. Adds regular expressions and their corresponding token IDs to the lexer.
3. Skips whitespace characters (spaces, tabs, and newlines) by assigning them a specific token ID.
