Plato is a JS code complexity analyzer.
The documentation can be found at that link. I cannot get it to run however. It must be a dumb mistake but here is what I have tried.
plato fileX.js -d somename "~/Desktop/"
plato addNewDocPopup.js -d "~/Desktop/"
Amongst many others :) I don't claim to be amazing at the command line but the error I get is:
Must specify a value for option d (dir : The output directory)
I could have sworn that is exactly what I'm doing... Maybe not...
Just a guess but maybe options must come before target file? plato -d ~/Desktop fileX.js. Also, don't put ~/Desktop in double quotes. That will prevent the shell from expanding the ~ into the path to your home directory for you.
