PyHorizon custom language interpreter

PyHorizon

PyHorizon is a tiny custom programming language written in Python. Program files use the .pyh extension and are executed by main.py.

Project Structure

• main.py - command-line entry point. Reads a .pyh file and runs it.
• lexer.py - converts source code into tokens.
• parser.py - turns tokens into an abstract syntax tree.
• ast_nodes.py - AST node definitions.
• interpreter.py - executes the AST.
• environment.py - variable scope handling.
• errors.py - readable lexer, parser, and runtime errors.
• tokens.py - token data model.
• example.pyh - sample program in the language.
• calculator.pyh - interactive calculator app written in PyHorizon.
• app.pyh - GUI app that opens a window.

Syntax

Supported commands:

• say "Hello"
• say Hello world name
• imp x = 10
• x = x + 1
• if x > 5 ... else ... end
• loop x < 10 ... end
• func add(a, b) ... end
• return value
• # comment

In say, plain words without quotes are treated as text, and variables are inserted automatically. Example:

imp name = Gh
say Hello name

ask reads user input and automatically converts numbers and booleans when possible:

imp value = ask Введи число

How It Works

1. The lexer reads text from a .pyh file and turns it into tokens.
2. The parser builds a structured tree of statements and expressions.
3. The interpreter walks that tree and executes the program.

Run
