Transcrypt features and specs

  • Python to JavaScript Transpilation
    Transcrypt allows you to write your code in Python, which is then transpiled into JavaScript. This enables Python developers to leverage their existing knowledge and skills to develop web applications.
  • Efficiency and Performance
    Transcrypt produces highly readable and compact JavaScript code, which can be optimized for better performance. The generated code includes optional source maps for debugging.
  • Access to JavaScript Libraries
    Transcrypt allows you to use JavaScript libraries seamlessly alongside Python code, enabling integration with existing JavaScript ecosystems.
  • Static Typing
    Transcrypt supports optional static typing, which can help catch errors earlier in the development cycle and make your code more robust.
  • Advanced Features
    Transcrypt supports advanced Python features such as multiple inheritance, tuple assignment, and list comprehension, providing a rich development experience.

Possible disadvantages of Transcrypt

  • Limited Python Support
    Only a subset of Python's standard library is supported, which might limit functionality that can be directly transpiled without modifications.
  • Compatibility Issues
    Certain Python constructs and idioms may not translate well into JavaScript, requiring developers to adapt their code specifically for web environments.
  • Learning Curve
    Although it enables Python development for the web, developers need to learn about the limitations and specifics of the transpilation process, which can be a barrier.
  • Community and Support
    Transcrypt has a smaller community compared to mainstream JavaScript frameworks, which can make finding support and resources challenging.
  • Development Overhead
    Transcrypt introduces an additional step in the build process, which might increase the complexity of the development and deployment workflow.

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.

  • PyScript
    This is a laudable effort, but I'm not a fan of shipping the entire interpreter. I looked around a few weeks ago and found https://transcrypt.org, which compiles your Python script to JS, so size is minimal. It's great for shipping small, internal tools/apps, I love how maintainable they are by all the Python devs, plus they're very fast to load and execute. - Source: Hacker News / about 4 years ago
  • PySketch: Python Playground for HTML5
    How is the Python being run by the browser? Several impressive projects bring Python to the browser, such as Brython, Transcrypt, Skulpt, Pyodide. PySketch uses Brython that compiles Python to JavaScript in the browser. You can take a look at this article about technologies and comparisons if you want to learn more. - Source: dev.to / over 4 years ago
  • How to actually use python code in browser or application?
    I have a Python program that takes user input from the console and shows some results on the console, and I want the user to be able to type stuff into it instead of pre-recorded runs. How do I do that? I'm not really sure. You could have a copy of Python running on the server and have the front-end communicating with it, but you'd have to be sure it's secured -- there are a lot of dangerous Python commands...

  • Use of python for software development
    For web apps: in my experience, there are tools that convert Python into JavaScript or try to make Python run inside a web browser like Brython and Transcrypt. These have been VERY awkward or painfully slow, so I would strongly discourage their use in practical web development. Source: about 5 years ago
  • Python and the Browser - Revisited
    A while back, I posted about my initial foray into using Python to develop front-end web applications with React by using the Transcrypt transpiler. Python in the Browser Part of the initial learning process I went through was doing the official React tutorial, but using Python for the code instead of JavaScript. When I did that, I adhered to the structure of the application that was used in the tutorial... - Source: dev.to / over 5 years ago

  • 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: almost 4 years ago

    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 / almost 4 years ago
