Running symbex with no arguments does nothing but pauses for ages

[simonw]

It recursively reads in every Python file it can find, but then scans them for no symbols and hence doesn't produce any output.

It shouldn't do all of that work for nothing.

It should probably display help.

[simonw]

Actually I think the solution is to say that symbols are required unless -s is specified.

Got this working:

 % symbex
Usage: symbex [OPTIONS] [SYMBOLS]...
Try 'symbex --help' for help.

Error: Invalid value: Either provide symbols to search for or use -s/--signatures

[simonw]

I want it to show help instead, this seems unfriendly.

[simonw]

Yes this feels much nicer:

% symbex
Usage: symbex [OPTIONS] [SYMBOLS]...

  Find symbols in Python code and print the code for them.

  Example usage:

      # Search current directory and subdirectories
      symbex my_function MyClass
  
      # Search using a wildcard
      symbex 'test_*'
