Clean All Except?

[pjdicke]

This is probably more of a feature request but it might be nice to do clean all except a file or dir?

Check out ! as that will negate a pattern. src: ['include/*.js', '!dont/include/*.js']. http://gruntjs.com/configuring-tasks#globbing-patterns

Perfect! thanks

@shama Not working consistently for me. +1

Apparently you must use exclude the directory and all its children, e.g.:

{
  // ...
  files: {
    '!path/to/your/directory'
  , '!path/to/your/directory/**/*'
  }
  // ...
}

@adjohnson916 ! negates a pattern. Since folder/**/* doesn't match folder but rather the contents of that folder; prepending ! won't negate folder either.

You also seem to have to use object.files notation. I used an array of paths before and that didn't work.

Works:

clean: { files:[
    "web/client/**/*.js*",
    "!web/client/libs/**/*.js*",
     "web/packages/**/*.js*",
    "!web/packages/omm/**/*.js*",
    "web/server/**/*.js*",
    "web/tests/**/*.js*"
] }

Doesn't work:

clean: [
    "web/client/**/*.js*",
    "!web/client/libs/**/*.js*",
     "web/packages/**/*.js*",
    "!web/packages/omm/**/*.js*",
    "web/server/**/*.js*",
    "web/tests/**/*.js*"
]
