Not writing files?

[mitchellst]

Still new to grunt, so sorry if this is ridiculous. I'm trying to convert some YAML files to json. Here's my task:

convert: {
  yaml2json : {
    files : [
      {
        expand: true,
        cwd: '_data',
        src: ['*.yml'],
        dest: 'json/',
        ext: '.json'
      }
    ]
  }
},

From what I can tell, that should take any YAML files in my _data directory and put them in a json directory with json extensions. So far so good. I run grunt convert --verbose and get:

Running "convert:yaml2json" (convert) task
Verifying property convert.yaml2json exists in config...OK
Files: _data/staff.yml -> json/staff.json
Files: _data/teachers.yml -> json/teachers.json
Files: _data/workshops.yml -> json/workshops.json
Options: pretty, mergeAttrs, inline=8, indent=2, csv={"columns":true,"delimiter":","}
Options: pretty, mergeAttrs, inline=8, indent=2, csv={"columns":true,"delimiter":","}
Reading _data/staff.yml...OK

Done, without errors.

It found the three files I wanted to convert, and knew where I wanted to put them. It reads in the first one, but then finishes. No JSON files were written. Anybody who could let me know what I missed, it'd be greatly appreciated.

Using versions:

grunt: 0.4.5
grunt-convert: 0.1.12
node: 4.1.1

I had the same issue. In my case it was the first YAML file which was not converted causing the issue.

For me it worked to replace the code for convert.js from the node module with the code here on Github. Then running in verbose gave an error message where the error in the yaml file exactly was.
