How many package managers can one language have? Its a simple language but setting it up is just incredibly bad. Maybe this is the one or should I wait for the next?
Out of the box, the Python extension redlines all the third-party imports.
As a workaround, I have to plunge into the guts of uv's Cache directory to tell VS Code the cached venv path manually, and cross fingers that it won't recreate that venv too often.
You can work around this surprising behavior by always using inline dependencies, or by using the `--project` argument but this requires that you type the script path twice which is pretty inconvenient.
Other than that uv is awesome, but this small quirk is quite annoying.
One gotcha I caught myself in with this technique is using it in a script that would remediate a situation where my home has lost internet and needed the router to be power cycled. When the internet is out, `uv` cannot download the dependencies specified in the script, and the script would fail. Thankfully I noticed this problem after writing it but before needing it to actually work, and refactored my setup to pre-i…
I wish there was a straightforward way to let VS Code pick up the venv that uv transparently creates. Out of the box, the Python extension redlines all the third-party imports. As a workaround, I have to plunge into the guts of uv's Cache directory to tell VS Code the cached venv path manually, and cross fingers that it won't recreate that venv too often.
I've been working on a VSCode extension to automatically detect and activate the right interpreter: https://marketplace.visualstudio.com/items?itemName=nsarrazi...

uv is so cool. haha. goodbye conda.
Love this feature of UV. Here's a one-liner to launch jupyter notebook without even "installing" it: uv run --with jupyter jupyter notebook Everything is put into a temporary virtual environment that's cleaned up afterwards. Best thing is that if you run it from a project it will pick up those dependencies as well.
Earlier quoted context omitted.
Completely agree. UV for stalled what was going to be a major project to move lots of python to golang. There will still be a lot migrated, but smaller script like things are no longer in scope.
I still write small some scripts in golang when the bootup time is important. Python still takes its time to boot up, and it's not the best tool for the job if it's gonna be called like a shell utility for thousands of files, for example.
They're the ones that just keep running in cron with zero modifications.
Python is when I need to iterate fast and just edit crap on the go, most of those will also be migrated to Go after they stabilise - unless there's a library dependency that prevents it.
`uv` is nice, but it's not "static binary that runs literally anywhere with no prerequisites" -nice

shebang mode is also incredibly useful and allows execution like ./script.sh #!/usr/bin/env -S uv run --script # /// script # dependencies = [ # "requests
