  • The text mode lie: why modern TUIs are a nightmare for accessibility
    > a locked down GUI that is efficient to use and designed to display the data that the commandline tools produce [...] You can have all that. There are various data presentation tools out there (one I can think of right now is Streamlit as I tried it out a few months ago, but I'm not really a data person, Python is just my primary language). For a more general GUI framework that's pretty easy to use and still full... - Source: Hacker News / 3 months ago

  • Using Uv and PEP 723 for Self-Contained Python Scripts
    It's more the latter, particularly when Rust is used in libraries (eg. FastAPI) as opposed to tools, as it's destroying portability. For example I use flet[0] in some of my projects, and I have to be increasingly careful about the other dependencies as there is no support for the Rust toolchain within Dart/Flutter, and even if there was it still sounds like it'd be a nightmare to maintain. Same applies to any... - Source: Hacker News / over 1 year ago

    The problem with all this combining is that it's making apps less portable.

  • Flet is "The fastest way to build Flutter apps in Python" - it's not :(
    "The fastest way to build Flutter apps in Python" is the title of Flet's web page. As someone coming from the Flutter world reading the line I draw an ideal picture of "swapping Dart language for Python and magically having the whole power of Flutter framework and the tips of your fingers". - Source: dev.to / almost 3 years ago

  • Inkscape (vector graphics editor) is hiring: Accelerating the GTK4 migration
    Web and Flutter support for other languages is debatable to be fair: you have webassembly so if your language of choice supports it as a compilation target you should be good, sure it doesn't count as a toolkit, but Blazor is a real example that relies on that, although you will need JS anyway to act on the DOM; Flutter has Flet that allows you to use it through Python and also other languages are coming if I'm...
