Brian # 1: Distinguishing in between listing dependences to make use of bundles and also for bundles themselves

• Brett Cannon
• Why can not we simply make use of pyproject.toml and also quit making use of requirements.txt?
• Nope. A minimum of not yet. They’re presently for various points.
• pyproject.toml.
  • There’s project.dependencies and also project.optional-dependencies. examinations that kinda would certainly help noting dependences for an application.
  • Yet you can not state pip set up -r pyproject.toml It does not function. Which’s strange.
  • job is meant for packaged tasks.
• requirements.txt.
  • for applications and also various other non-packaged tasks
  • It has particular variations
  • functions fantastic with pip
• What after that?
  • Either we stick to requirements.txt
  • Or we create a few other documents, possibly requirements.toml?
  • Or possibly (Brian’s remark), include something like [application] and also application.dependencies and also application.optional-dependencies. examinations to pyproject.toml

Michael # 2: PythonMonkey

• PythonMonkey is a Mozilla SpiderMonkey JavaScript engine installed right into the Python VM, making use of the Python engine to offer the JS host setting.
• This item remains in a beginning, around 80% to MVP since July 2023. It is under energetic advancement by Distributive Outside payments and also responses rate and also urged.
• It will certainly make it possible for JavaScript collections to be utilized perfectly in Python code and also the other way around– with no considerable efficiency charges.
• Call Python bundles like NumPy from within a JavaScript collection, or make use of NPM bundles like [crypto-js]( https://www.npmjs.com/package/crypto-js) straight from Python.
• Carrying out WebAssembly components in Python ends up being unimportant making use of the WebAssembly API and also engine from SpiderMonkey.
• Even more information in Will certainly Pringle’s write-up

Brian # 3: Peculiarities of Python bundle versioning

• Seth Larson
• Yes, we have SemVer, 1.2.3, and also CalVer, 2023.6.1, and also suffixes for beta, 1.2.3 pre1.
• Yet it obtains way much more enjoyable than that, if you obtain imaginative
• Below’s a couple of.
  • v is an optional prefix, like v. 1.0
  • You can consist of an “Date” and also divide it from the variation with a !, like 20! 1.2.3
  • Neighborhood variations with alphanumerics, durations, dashboards, highlights, like 1.0.0+ ubuntu-1 PyPI turns down those. That’s most likely great.
  • Lengthy variations. There’s no max size for a variation number. Just how around 1.2.3.4000000000000000001?
  • Pre, blog post, dev aren’t equally unique: 1.0.0-pre0-post0-dev0
  • Extra insaneness in write-up

  • Call those callables with legitimate criteria: Clear
  • Call those callables with void criteria: Boom
