"raco pkg install" rejects directory names and certain archive names with "." characters in them

[dnm]

What version of Racket are you using?
8.4

What program did you run?

C:\Users\Etaoin Shrdlu\Hack\rosette-4.0>raco pkg install

What should have happened?
I expected this to be a valid package name as a directory package; I believe (but cannot readily test at the moment) that in somewhat previous versions of Racket (CS 7.x builds) I didn't encounter this problem.

If you got an error message, please include it here.

Linking current directory as a package
raco pkg install: invalid package source;
 inferred package name includes disallowed characters
  given: C:\Users\Etaoin Shrdlu\Hack\rosette-4.0\

Please include any other relevant details
I tested this with different permutations of the directory name (e.g., "rosette-4.0", "rosette-4", "rosette4.0", and "rosette4") and found that directory names containing "." characters were rejected with the same error above.

I also did the same with .zip archives instead of the package expanded into a directory, just as another test (e.g., "C:\Users\Etaoin Shrdlu\Hack>raco pkg install rosette-4.0.zip"), with the same permutations of archive names (i.e., "rosette-4.0.zip", "rosette-4.zip", "rosette4.0.zip", and "rosette4.zip") and experienced the same behavior with these names with respect to error messages about disallowed characters in inferred package names as I did with the directory examples.

I suspect after "raco pkg install" identifies the file extension, it considers other "." characters illegal in the rest of the package name. Some archive file extensions/suffixes can contain one or more "." characters: while ".zip" has only one, ".tar.gz" has two, and "raco pkg install" doesn't complain about e.g., "raco pkg install rosette-4.tar.gz" but does with "raco pkg install rosette-4.0.tar.gz")

You can give a --name so that it doesn't use the inferred name that has a .. Running raco pkg install --name rosette should fix your problem.
