Brian #1: Switching to direnv, Starship, and uv

• Last week I mentioned that I’m ready to try direnv again, but secretly, I still had some worries about the process. Thankfully, Trey has a tutorial to walk me past the troublesome parts.

• direnv - an extension for your shell. It augments existing shells with a new feature that can load and unload environment variables depending on the current directory.

• Switching from virtualenvwrapper to direnv, Starship, and uv

  - Trey Hunner**

  • Trey has solved a bunch of the problems I had when I tried direnv before

    • Show the virtual environment name in the prompt

    • Place new virtual environments in local .venv instead of in .direnv/python3.12

    • Silence all of the “loading”, “unloading” statements every time you enter a directory

    • Have a script called

      venv
      

      to create an environment, activate it, create a

      .envrc
      

      file

      • I’m more used to a create script, so I’ll stick with that name and Trey’s contents

    • A

      workon
      

      script to be able to switch around to different projects.

      • This is a carry over from “virtualenvwrapper’, but seems cool. I’ll take it.

    • Adding

      uv
      

      to the mix for creating virtual environments.

      • Interestingly including --seed which, for one, installs pip in the new environment. (Some tools need it, even if you don’t)

  • Starship

    • Trey also has some setup for Starship. But I’ll get through the above first, then MAYBE try Starship again.
    • Some motivation
      • Trey’s setup is pretty simple. Maybe I was trying to get too fancy before
      • Starship config in toml files that can be loaded with direnv and be different for different projects. Neato
      • Also, Trey mentions his dotfiles repo. This is a cool idea that I’ve been meaning to do for a long time.

Michael #2: rqlite - Distributed SQLite DB

• via themlu, thanks!
• rqlite is a lightweight, user-friendly, distributed relational database built on SQLite.
• Built on SQLite, the world’s most popular database
• Supports full-text search, Vector Search, and JSON documents
• Access controls and encryption for secure deployments

Michael #3: A Python dict that can report which keys you did not use

• by Peter Bengtsson
• Very cool for testing that a dictionary has been used as expected (e.g. all data has been sent out via an API or report).
• Note: It does NOT track d.get(), but it’s easy to just add it to the class in the post.
• Maybe someone should polish it up and put it on pypi (that person is not me :) ).

Brian #4: Some Markdown Stuff

• Textual 4.0.0

  adds Markdown.append which can be used to efficiently stream markdown content

  • The reason for the major bump is due to an interface change to Widget.anchor
  • Refreshing to see a symantic change cause a major version bump.

• html-to-markdown

  • Converts html to markdown

  • A complete rewrite fork of markdownify

  • Lots of fun features like “streaming support”
    • Curious if it can stream to Textual’s Markdown.append method. hmmm.
