XLang-Rust

XLang-Rust is a Rust implementation of the XLang programming language, designed to provide a cross-platform, experimental, dynamically strong-typed programming environment. It executes scripts through a virtual machine and offers a unique set of language features.

Features

• Dynamically Strong Typed: Variable types are determined at runtime, but type errors raise exceptions.
• Expression-Based: Statements are sequences of expressions, with the result of the last expression being the statement's result. The syntax style is similar to Rust.
• Lambda Core: Functions are defined and called entirely using Lambda functions, allowing Lambdas to cache their last call's parameters and return value.
• Tuples: The primary ordered collection type, which are mutable and support indexing, key-value pairs, and named parameters.
• Single-Threaded Async Tasks: Implements cooperative concurrency through async/await for managing tasks that interleave execution on a single thread (note: behavior differs from traditional suspendable/resumable coroutines).
• Non-Local Control Flow: Uses boundary/raise to implement non-local jumps more powerful than return.
• Object Binding: Simulates object-oriented behavior through the bind keyword.
• Alias System: Attaches static aliases to objects using ::.
• Rich Built-in Types: Includes integers, floats, booleans, strings, byte sequences, ranges, key-value pairs, named parameters, and more.
• Toolchain: Provides REPL (repl), compiler (compile to .xir or .xbc), runner (run), IR viewer (display-ir), bytecode translator (translate), and LSP server (lsp).

Status

XLang-Rust is currently in an experimental phase. Its design incorporates some unique concepts and behaviors that may differ from other mainstream languages. Feedback and experimentation are welcome.

Quick Start

Assuming the compiler executable is named xlang-rust:

1. Run a Script File:

   xlang-rust run your_script.x

   You can also run intermediate code (.xir) or bytecode (.xbc) files.

2. Compile to Bytecode:

   xlang-rust compile your_script.x -b -o your_script.xbc

   (-b indicates compiling to bytecode, -o specifies the output file)

3. Start the REPL:

   xlang-rust repl
