Processing doesn't recognize methods of PApplet when the sketchfolder has a hyphen in it

[mythicaleinhorn]

Description

When the name of a sketch folder contains a hyphen, Processing doesn't recognize the methods of PApplet like draw(), background(), etc.
The sketch will compile and run without any problems anyway.

Steps to Reproduce

1. Create a sketch in a folder with a name containing a hyphen
2. A sketch.properties file is created pointing to the main file (which can't have a hyphen in it, Processing will refuse to start in that case)
3. Processing won't recognize the methods of PApplet anymore (draw(), background(), etc.)

Your Environment

• Processing version: 4.1.1
• Operating System and OS version: TUXEDO OS 1 (KDE Plasma) / Windows 11
• Other information: This problem exists since 4.1.0

Suggested fix:
Adding a check similar to https://github.com/processing/processing4/blob/1e1d1964eef5a2660296d56ce68f4612b1c9e33e/app/src/processing/app/Base.java#L1606-L1615 to check for hypens in a folder name.

This does not happen on OSX. But it does indeed happen on windows.
The thing is, instead of a "sanitary check", it would be better to find why it breaks with a hyphen and fix that.

@sampottinger Any quick thoughts? (Not your fault, just that you were in this code recently dealing with incorrect/superficial errors/warnings being reported.)

This is another split between the live error checking and the generated code that's actually run. It looks like there's probably an assumption about class name being the same as the main tab name or the folder name, so this is showing errors when the sketch folder doesn't match up (i.e. it has spaces, hyphens, anything else that's now allowed if you un-check “Keep sketch name and main tab in sync”.

Weird. Yeah it could be something with the edt edit generation. It's strange that it is OS specific though. I'll take a look.

I'm seeing it on macOS, I don't think it's OS-specific. To reproduce:

1. Uncheck the pref to keep sketch name and tab in sync
2. Do a “Save As” and re-save the sketch to a folder that has spaces or hyphens in the name
3. You should see red squiggles in the editor area for built-in functions

(i.e. potentially nearby the other bit you had just fixed w/ error squiggles.)

Ah I must have misinterpreted an earlier comment. I'll try to take a look tomorrow!

Actually I think I have a minute let me pop in now @benfry

All set for 4.1.2 thanks to @sampottinger.
