Hy features and specs

  • Python Interoperability
    Hy seamlessly integrates with Python, allowing you to use the entire Python ecosystem while writing your code in a Lisp-like syntax. This interoperability makes it easier for developers familiar with Python to experiment with Lisp's syntax and ideas.
  • Lisp Syntax and Macros
    Hy provides Lisp's powerful macro system and syntax, enabling more expressive and concise code. The ability to create macros can lead to highly customizable and domain-specific solutions.
  • Readability
    For those familiar with Lisp, Hy offers increased readability due to its minimal syntax and symbolic expressions. This can lead to more straightforward reasoning about the code and reduced syntactic noise.
  • Compiles to Python
    Hy code is compiled to Python bytecode, allowing it to run on any environment where Python is available. This ensures good performance and compatibility with existing Python tools and utilities.

Possible disadvantages of Hy

  • Steep Learning Curve
    For developers not familiar with Lisp, Hy's syntax and concepts (like macros) can be difficult to grasp initially. This can slow down development time as developers need to learn new paradigms.
  • Limited Adoption
    Hy is not as widely adopted or supported as some other languages or even other Lisp implementations. This can lead to less community support, fewer third-party libraries written specifically for Hy, and potentially more difficulty finding solutions to problems.
  • Debugging Complexity
    Debugging in Hy can sometimes be more challenging because errors may occur in the compiled Python code rather than the original Hy code, which can complicate traceback and error understanding.
  • Macro Overuse
    While macros are a powerful feature, their misuse can lead to code that is hard to read and maintain. This can become a con if developers do not exercise restraint and best practices in their use.
  • Performance Overhead
    While Hy compiles to Python, the added layer of abstraction and translation may introduce small performance overheads compared to writing natively in Python, especially for performance-critical applications.

CMU Common Lisp features and specs

  • High-Performance Compiler
    CMU Common Lisp features an efficient native code compiler that can produce highly optimized code for the supported platforms, enhancing performance for computationally-intensive applications.
  • Extensive Library Support
    Includes a wide variety of libraries, providing functionality ranging from numerical computing to system interfacing, which allows developers to implement diverse applications without relying heavily on external packages.
  • Strong Typing System
    CMUCL provides a strong type system with good error detection and optimization capabilities that can help catch errors at compile-time and improve runtime performance.
  • Garbage Collection
    It includes an efficient garbage collector that manages memory naturally, minimizing manual intervention and reducing memory leaks and fragmentation in applications.
  • Comprehensive Integrated Development Environment
    CMUCL comes with an integrated environment which includes a debugger, inspector, and an interface for efficient development and troubleshooting.

Possible disadvantages of CMU Common Lisp

  • Limited Platform Support
    The number of platforms explicitly supported by CMUCL is limited, which can be a constraint for developers who need to work across multiple or newer systems.
  • Steep Learning Curve
    Newcomers might find CMUCL challenging due to its complexity and the intricate features specific to Lisp, requiring a steep learning curve compared to more modern languages and environments.
  • Outdated Documentation
    Some users find the documentation to be outdated or not comprehensive enough, making it difficult to get started and fully leverage the system's capabilities.
  • Limited Community Support
    The user and contributor community for CMUCL is relatively small compared to other languages and projects, which may result in less frequent updates and fewer third-party resources.
  • Complex Setup Process
    Initial setup and configuration of CMUCL can be cumbersome, especially for users not familiar with Lisp environments or those who require specific custom configurations.

  • How trying new programming languages helped me grow as a software engineer
    I really like Hy because it's fully inter-operable with Python. But its documentation is insufficient for anything moderately complex, and its tooling support is pretty basic. If Hy were well documented and supported I'd use it for all my throwaway scripts and prototyping -- today I use Python for that. Source: over 2 years ago

  • Val on Programming: What makes a good REPL?
    I've been using the Hy REPL[0] whenever I've wanted to drop into a python REPL. The lack of whitespace formatting with Hy is great, but it still has access to all of python's libraries. [0] - https://docs.hylang.org/en/stable/. - Source: Hacker News / over 2 years ago
