Linting stops working or displaying in Atom with pyls > 0.31.2

[hermidalc]

After upgrading pyls on conda-forge from 0.31.2 -> 0.31.3 or 0.31.4 then ide-python suddenly stops showing any lint comments/warnings/errors. When I downgrade back to 0.31.2 then everything shows up again.

Atom 1.42 (on linux)
ide-python 1.5.0

Me too, I can help the pack?

I also have this problem but I still didn't get the linting after downgrading pyls to 0.31.2. I wonder if anyone has a solution for this?

But my Windows system works fine, which is quite strange.

However, this kit is also dependent on Facebook's Atom IDE UI, and Facebook also stopped maintaining this kit. Maybe we should find a way to move to other UI interfaces, or whether we can make improvements in the dependent Atom IDE UI.

Not sure how you had linting working with 0.31.2, then upgraded to 0.31.3 or 0.31.4 and lost it, then downgraded back to 0.31.2 and linting doesn't come back. I performed the upgrade and downgrade a few times to make sure it was the version upgrade causing the problem and with each downgrade to 0.31.2 linting worked again. I would check there isn't something else you've done that is causing your problem.

Thank you! I have typed the command python -m pip install 'python-language-server[all]' again and nothing was installed (because version 0.31.2 has been installed already). Weird though, I got the linting back in my Atom now!

I have no idea why did that happen but I am glad the linting is back! I love this feature and thank you!

I installed ide-python for the first time and it does not work. I always get the message that pyls should be installed, but it is. I followed the instruction, even did the specific install of "0.31.2", as it seems to be the version that works for you. :)

When i to the command to check if it is installed (python -m pyls --help), I get:

usage: __main__.py [-h] [--tcp] [--host HOST] [--port PORT] [--check-parent-process] [--log-config LOG_CONFIG | --log-file LOG_FILE] [-v]

In the example in the README is says: usage: pyls instead of usage: __main__.py ... is there a problem and how do I fix it?

I’m pretty sure your problem is different than what is described in this issue. Not even certain it’s ide-python could be pyls or something else in your local setup or install.

crazy... I had to set the "Python Executable" to "/usr/bin/python" ... which is my default python which is called when you type "python".
Thanks for the reply :)

Same problem for me:

Global versions

• Atom==1.44.0
• ide-python==1.5.0
• Linux OS: ubuntu==18.10

Tests

• (1) python3.7 (in settings)
  • python3.7 -m pip install python-language-server==0.29.0 (minimum required version for the ide-python to work)
  • Result: error and warnings are displayed
• (2) python3.7 (in settings)
  • python3.7 -m pip install python-language-server==0.31.2 (or newer, I haven't test all the version between 0.29.0 and 0.31.2)
  • Result: error and warnings are NOT displayed
• (3) python3.8 (in settings)
  • python3.8 -m pip install python-language-server==0.29.0 (and same for 0.31.2)
  • Result: error and warnings are displayed, EDIT: But for 0.31.2, a removed previously displayed warning or error is still displayed
• (4) python3.8 (in settings)
  • python3.8 -m pip install python-language-server==0.31.8 (or >= 0.31.3)
  • Result: error and warnings are NOT displayed

Thank you for your work

EDIT:
It seems that pyflakes is broken with python 3.8 ...
Associated log error: Python (pyls) stderr AttributeError: 'Checker' object has no attribute 'NAMEDEXPR'

PyCQA/pyflakes#457

TEMPORARY SOLUTION:
python3.8 -m pip uninstall pyflakes
python3.8 -m pip install git+https://github.com/pycqa/pyflakes

@lgeiger no pressure, just wondering out of interest, are you not going to maintain ide-python anymore given that atom-ide-ui isn't developed and maintained by Facebook anymore?

I think atom-ide-ui, the language server protocol, and packages for each language based off it were some of the best things about Atom, including ide-python. I only had to install one conda package and one Atom package for each language I use and it came loaded with everything you need. Before that I had to install and set up a pair of packages for each individual programming tool I wanted. I guess I could go back to that.

@hermidalc Thanks for asking. I agree ide-python hasn't received enough attention from my side lately. Largely due to the fact that I now have a full time job instead of being a lazy student, I no longer have so much time and energy to maintain ide-python and answer issues.
However this doesn't mean the project is abandoned. I still use it on a daily basis and will provide critical fixes, merge PRs or add support for new features from the language server.
I really encourage everyone who is interested in seeing this project evolve further, to keep answering questions and help to improve the documentation and user experience of ide-python. I am more than happy to give commit access too people interested in helping maintain ide-python.

As a replacement for atom-ide-ui, I can highly recommend the community supported IDE packages which provide 80% of the functionality and are maintained by the Atom IDE community.

@lgeiger thanks for the response. The most pressing thing right now regarding this issue is that ide-python does not work anymore with newer versions of pyls, so would consider this a semi-critical issue.

I use ide-python every day like you for a long time and think it’s really great.

Thanks for pointing me to this page, I thought all the ide-* language packages needed atom-ide-ui so glad to hear there are some workarounds.

I am currently using pyls==0.31.8 and the latest versions of https://atom-ide-community.github.io/ instead of atom-ide-ui with Python 3.7.7 on macOS and I haven't run into any issues so far. So unfortunately I am not in a good place to debug those issues.
