It's a small code, look for good

share and feel happy 😂

when you want to compile an open source program, it's like this, I waited for 2 hours and he said checking,

this is python

Canva is a clear thief, I will not let them rob me

yes, without notifying you or not telling you the purpose, canva will takes the money

someone his story WhatsApp

I plan to add class() to lua, because lua is a pop language and not an oop like python, java

I will post it on github wherever I do, welcome to participate

hello all
ask me question about any problem! 👇

lexer programming

I've given up on lua, but reading extensively on lua and all opensource languages I wanted to build a language from scratch.

This code is used to separate any ID, STRING, SEMICOLON, BRACKET

Lexer, parser, and visitor are three important components of a compiler or interpreter.

A lexer (short for lexical analyzer) is responsible for breaking down the input source code into a sequence of tokens. Tokens are the smallest units of meaning in a programming language, such as keywords, identifiers, operators, and literals.

A parser is responsible for analyzing the sequence of tokens produced by the lexer and constructing a parse tree, which represents the syntactic structure of the program. The parse tree is a hierarchical structure that shows how the different parts of the program are related to each other.

A visitor is a design pattern that is often used in conjunction with a parse tree. A visitor allows you to traverse the parse tree and perform some operation on each node. For example, you might use a visitor to evaluate the value of an expression, or to generate code for a particular target platform. The visitor pattern separates the algorithm from the data structure, making it easier to add new operations without modifying the existing code.
