RedPen plugin does not work with IntelliJ IDEA CE 2018

[johnblommers]

We had a working RedPen with IntelliJ IDEA CE 2017.3.4. Then we used the update process within IDEA to bring it to the 2018.1.1 version. Now the red wiggly lines of RedPen never appear. The only workaround we found is to delete the 2018 version of IDEA and reinstall the 2017 version.

This is on macOS X 10.11.6 El Capitan. We're using the RedPen IntelliJ Plugin 1.8.1.

Thank you very much for the valuable report @johnblommers! I will look into the problem.

It'd be nice to have a fix for this, as IntelliJ 2018.x have been out for a while now.

Hi @hameerabbasi, Thank you for the remind. I tried RedPen plugin in IntelliJ 2018.1 and confirmed the plugin works.

The following is the image of the IntelliJ.

This problem might be PyCharm specific then. I'm going to Settings > Preferences and clicking browse repositories. Then, searching for RedPen and clicking Install.

After it downloads, it doesn't ask for an IDE restart or tell me that the plugin is installed. I can't find it in my plugin list either.

I see. I will try RedPen with PyCharm.

Reproduced error in PyCharm.

Got the following error messages in ~/Library/Logs/PyCharmCE2018.1/idea.log.

I can't tell from this on reading the traceback... Is this a PyCharm issue, a RedPen issue, or a plugin distribution issue? Maybe your filename is compatible with IntelliJ but not with PyCharm for some reason? Maybe the server is messing with filenames for different IDEs? Just throwing ideas out here.

Confirmed we can install RedPen plugin downloading from plugin home page.

https://plugins.jetbrains.com/plugin/8210-redpen-plugin

Download the zipped plugin file from the above URL and expand it in the plugin directory described in the following page.

https://stackoverflow.com/questions/1226066/how-do-i-install-a-specific-version-of-an-idea-plugin

I still do not know why we cannnot install the plugin from the IntelliJ UI...

Finally I succeeded to install RedPen in Pycharm through UI. @hameerabbasi Can you please try it again?

[hameerabbasi]

I’ll check tomorrow, hopefully.

I just tested. The installation from UI works fine now. Haven't tested for any other bugs, though.

Thanks! I close this issue.
