[question][macOS] The default Arduino data directory location on macOS

[kittaakos]

Bug Report

Current behavior

I am not sure if this is a bug, but the CLI has a different default data directory location than the one the Arduino editor uses.

For the CLI, it is ardunio15:

arduino-cli/configs/directories.go

Line 47 in 296c872

return paths.New(userHomeDir).Join("Library", "arduino15"), nil

In case of the editor, it is Arduino15:
https://github.com/arduino/Arduino/blob/fb9ce0ade323f6f36793f29d615db1272d184ba4/arduino-core/src/processing/app/macosx/Platform.java#L80

Expected behavior

Environment

• CLI version (output of arduino-cli version):
• Go version (if building from sources):
  go version go1.12.6 darwin/amd64
• OS version:
  macOS 10.14.4 (18E226).

Additional context

[gvarisco]

I noticed this yesterday on macOS 10.14.6 as well.

tl;dr: @kittaakos is right, the name of the folder is not consistent (arduino15 vs Arduino15). But given starting w/ macOS 10.12 High Sierra, the default FS changed to case-insensitive APFS, there are no strange behaviors happening.

But to be on the safe side, I do suggest we resolve all case-sensitivity naming conflicts (that is, IDE and CLI) to be consistent. Keeping in mind macOS' capitalization "best practice".
