Building a lexer from scratch can be complex and error-prone. Instead, leveraging existing libraries like Logos simplifies tokenization significantly. This guide demonstrates how to integrate Logos as the lexer for a toy language parsed with LALRPOP. Consider the follownig input: var a = 42; var b = 23; # a comment print (a - b); Depandency S ...

When working with lexical analysis, clean separations between tokens are not always straightforward. Consider a language with string literals where variables are single characters: x = "a" y = "bc" An initial grammar attempt might look like this: use super::{Var, Lit, Eql}; grammar; pub Var: Var = <r"[x-z]"&g ...

Overveiw This article discusses several classic simulation problems that involve network string processing. Each problem requires parsing structured text, handling patterns, and implementing matching or replacement logic. The solution are written in C++ using standard libraries. Template Generation System The first problem involves a template e ...

Building upon prior work that automatically inserts signal declarations into C++ header files, this article focuses on automating the insertion of corresponding function definitions into implementation (.cpp) files. Since .cpp files are generally less complex than headers—lacking class structures and access specifiers—their parsing and modifica ...
