today I build a flake8 plugin from scratch showing the bare minimum to add a new lint check! I also demo all the related tools I use to make this happen: astpretty, pytest, flake8, and a little bit of python packaging!
- flake8: gitlab.com/pycqa/flake8
- flake8-2020: github.com/asottile/flake8-2020
- astpretty: github.com/asottile/astpretty
- pytest: github.com/pytest-dev/pytest

I love your videos. Today I thought one company-specific plugin would be helpful, but I thought it'll be hard to write it. And now I just watched your video and wrote it about an hour.

Thanks for the video, it's really helpful. I am making my first plugin and this is pretty helpful

Hey, I watch your streams and I just found out that you talk about some really cool stuff here on your channel. On stream you do a lot of open source programming and a big part of that (it seems) is your masterful usage of git. You seem to know your way around git and it would be interesting if you can make a video about semi-advanced usage of git in a "open source" setting. Like, what you most commonly use in git while developing, some tricks that you've acquired over the years and some things that you think are worth knowing. I would love learning about git from you!

I have a few git-related ones planned! should be coming soon :)

This was super informative! I have never used the ast module. Any suggestions on how to get started playing around with ast?

@anthonywritescode Год назад

no real suggestions beyond just doing something with it! astpretty is helpful for visualizing

Great Video! I have one Question: is it possible to make the checks depending on the filename? for example to check if a class is defined in a file which has the filename as the classname? I guess this needs to be done before the plugin is loaded?

@Schulesucks 2 года назад

I found the solution. If someone else needs ist: you can just get filename as an input parameter of the init method in plugin (after tree)

@anthonywritescode 2 года назад

you can, but it's kind of a bad idea -- for instance your code may be fed through `--stdin` and won't know what file its in
