What does the yellow background on filename mean in Intellij?

Question

I think it might have something to do with asynchronous tasks but I don't know for sure. Could someone please clarify this for me?

Also what do the yellow frames mean when you are debugging?

Solution 1

This color indicates the non-project files (libraries), you can customize it here:

Make sure to restart the debugger for the changes to have effect.

Solution 2

If this suddenly happens to your project:
Consider closing pycharm and deleting the .idea/ folder of that project.

After reopening the project the project, pycharm will detect all files as normal. But you'll need to set up the project again. -> Set source-folder, add run configuration etc.

For me that was the faster solution than figuring out how to fix it.

One more mention: It happened after a merge which caused some version conflicts and required to "roll back" a file.

Solution 3

This also happened to me and the cause was that the project folder was removed from the 'project structure'. You can re-add it in Settings-> Project <...> -> Project Structure.

See also the documentation: https://www.jetbrains.com/help/pycharm/configuring-project-structure.html

Solution 4

The above solution did not work for me -- by happenstance, I was clicking around the settings in Intellij/GoLand and stumbled across a solution that worked for me.

When I went to the Project Structure, the Project Structure pane was empty and there was no way for me to manually re-add my project directory.

Fix that worked for me: Top Menu Bars -> File -> Repair IDE

A bubble window shows up on the bottom right, and I just clicked through the tooltips to repair different aspects of Intellij. In my case, the 'Reindex Project Structure" step worked for me (it was Step 3 of 6 in the repair process).

After repairing + waiting a bit for the project to reindex, everything went back to normal.

My files used to be project files and sudenly turned to be non-project files. After a PyCharm update, looks like it's a bug

thanks. I was deleting .idea directory inside intellij. You need to make sure to close intellij first and then delete the directory.
