Poe the Poet

I was looking for a way to specify additional commands in my pyproject.toml file to execute using uv. There's an enormous issue thread on this in the uv issue tracker (300+ comments dating back to August 2024) and from there I learned of several options including this one, Poe the Poet.

It's neat. I added it to my s3-credentials project just now and the following now works for running the live preview server for the documentation:

uv run poe livehtml

Here's the snippet of TOML I added to my pyproject.toml:

[dependency-groups]
test = [
    "pytest",
    "pytest-mock",
    "cogapp",
    "moto>=5.0.4",
]
docs = [
    "furo",
    "sphinx-autobuild",
    "myst-parser",
    "cogapp",
]
dev = [
    {include-group = "test"},
    {include-group = "docs"},
    "poethepoet>=0.38.0",
]

[tool.poe.tasks]
docs = "sphinx-build -M html docs docs/_build"
livehtml = "sphinx-autobuild -b html docs docs/_build"
cog = "cog -r docs/*.md"

Since poethepoet is in the dev= dependency group any time I run uv run ... it will be available in the environment.

LLM 0.28

I released a new version of my LLM Python library and CLI tool for interacting with Large Language Models. Highlights from the release notes:

• New OpenAI models: gpt-5.1, gpt-5.1-chat-latest, gpt-5.2 and gpt-5.2-chat-latest. #1300, #1317
• When fetching URLs as fragments using llm -f URL, the request now includes a custom user-agent header: llm/VERSION (https://llm.datasette.io/). #1309
• Fixed a bug where fragments were not correctly registered with their source when using llm chat. Thanks, Giuseppe Rota. #1316
• Fixed some file descriptor leak warnings. Thanks, Eric Bloch. #1313
• Type annotations for the OpenAI Chat, AsyncChat and Completion execute() methods. Thanks, Arjan Mossel. #1315
• The project now uses uv and dependency groups for development. See the updated contributing documentation. #1318

That last bullet point about uv relates to the dependency groups pattern I wrote about in a recent TIL. I'm currently working through applying it to my other projects - the net result is that running the test suite is as simple as doing:

git clone https://github.com/simonw/llm
cd llm
uv run pytest

The new dev dependency group defined in pyproject.toml is automatically installed by uv run in a new virtual environment which means everything needed to run pytest is available without needing to add any extra commands.
