Save output to a file

[paazmaya]

Allow to use Grunt task files property for setting the destination file where the output will be directed instead of stdout in case it is defined.

Example usage

csscss: {
      options: {
        outputJson: true
      },
      dist: {
        'csscss.json': ['css/*.css']
      }
    }

Nice idea :) Will take a look at this for you.

[paazmaya]

Thank you!

Before that, I can just run the command by hand with > csscss.json

[peterkeating]

Played around with your idea last night, Managed to get something together, however my concern is when using the glob feature to process multiple files and outputting JSON, the JSON is not valid. Below is an example.

[]
[]
[{"selectors":[".rule-b",".rule-c"],"count":2,"declarations":["border: 1px solid #000","margin: 0"]}]

Any thoughts?

[paazmaya]

Are you referring to this? http://gruntjs.com/configuring-tasks#globbing-patterns

I was thinking something like

csscss: {
      options: {
        outputJson: true
      },
      dist: {
        'csscss.json': ['css/*.css'],
        'csscss_other.json': ['other/*.css']
      }
    }

Which would create single file for the given set of source files.

But if you mean that single src that contains for example * in this case, would result that invalid json, then each of the resulting arrays should be keys with src filename and wrapped in a object to make it valid.

Taken the example from your comment, the resulting output would be something like this:

{
  "file1.css": [],
  "other.css": [],
  "some.css": [{"selectors":[".rule-b",".rule-c"],"count":2,"declarations":["border: 1px solid #000","margin: 0"]}]
}

[peterkeating]

That's exactly what I mean with regards to a single src that contains *.

I was also thinking the resulting output would look like what you've specified.

[paazmaya]

But are you getting those array per f.src ?
If yes, then just save them to a internal data storage and once the given destination is handled, save that data in it.
I am sure you already tried.... so can you push the version to another branch?

[peterkeating]

Looks like I have fallen into a trap with this task as point out in this article. I am using this.data but I should be using this.files. Now I could just add a dest property that can be accessed via this.data.dest, or I could do it the proper way and refactor the task to use this.files.

Apologies :( Will get it sorted today / this evening!

[peterkeating]

Pushed the branch up for you. If you could give it a test that would be great, let me know how it goes and if there are any issues.

[paazmaya]

Thank you very much, I will look at it soon. Had a busy and long weekend...

With the example in #8 (comment)
I get File: [no files] once running grunt csscss -v.
