Michael #1: SQLCodeGen

• via Josh Thurston
• This is a tool that reads the structure of an existing database and generates the appropriate SQLAlchemy model code, using the declarative style if possible.
• This tool was written as a replacement for sqlautocode, which was suffering from several issues (including, but not limited to, incompatibility with Python 3 and the latest SQLAlchemy version).
• Features:
  • Supports SQLAlchemy 1.4.x
  • Produces declarative code that almost looks like it was hand written
  • Produces PEP 8 compliant code
  • Accurately determines relationships, including many-to-many, one-to-one
  • Automatically detects joined table inheritance
  • Excellent test coverage

Brian #2: The death of setup.py*, long live pyproject.toml

• for Python-only projects
• Juan Luis Cano Rodriguez tweet
• pip install --``editable . now works with setuptools, as of version 64.0.0
• To be clear, setup.cfg also not required.
• So everything can be in pyproject.toml
• The * part: projects with non-Python bits may still need setup.py
• See also the newly updated tutorial by the PyPA: Packaging Python Projects
  • Now with absolutely no mention of setup.py or setup.cfg
  • It’s all pyproject.toml
• Commentary:
  • For Python only projects, is setuptools a decent flit contender???
  • stay tuned

Michael #3: aiocache

• via Owen Lamont
• In the same vein as async-cache you might also be interested in aiocache.
• It has some cool functionality like an optional Redis backend for multi process caching.
• his library aims for simplicity over specialization. All caches contain the same minimum interface which consists on the following functions:
  • add: Only adds key/value if key does not exist.
  • get: Retrieve value identified by key.
  • set: Sets key/value.
  • multi_get: Retrieves multiple key/values.
  • multi_set: Sets multiple key/values.
  • exists: Returns True if key exists False otherwise.
  • increment: Increment the value stored in the given key.
  • delete: Deletes key and returns number of deleted items.
  • clear: Clears the items stored.
  • raw: Executes the specified command using the underlying client.

Brian #4: Hatch : a modern, extensible Python project manager

• Another flit contender?
• While reading Packaging Python Projects tutorial update, I noticed some examples for hatchling, as an alternative to setuptools, flit-core, and pdm.
• Played with it some, but still have some exploring to do.
• features
  • Standardized build system with reproducible builds by default
  • Robust environment management with support for custom scripts
  • Easy publishing to PyPI or other sources
    • includes --repo flag to be able to publish to alternative indices.
    • Awesome for internal systems.
  • Version management
  • Configurable project generation with sane defaults
  • Responsive CLI, ~2-3x faster than equivalent tools
    • This sounds great. I haven’t verified this
• Commentary:
  • Good to see more packaging tools and user workflow explorations around packaging.
