[Question] What type of regex is supported by the Lua.Docs.* setting

[NeOzay]

in the documentation, for packageName, privateName and protectedName we have no information on the forms that the pattern can take

is it possible to differentiate _fieldname and _fieldname_?

[PinewoodPip]

They use LPeg.
Ex. to use names with leading underscore as private you can use

"Lua.doc.privateName": [
    "_[a-z]*",
    "_[A-Z]*"
]
