Usage Examples

Flip one file

In this example, a single file is flipped.

grunt.initConfig({
  flipcss: {
    app: {
      files: {
        'css/main-rtl.css': 'css/main.css'
      }
    }
  }
})

Flip multiple files

In this example, multiple files are flipped.

grunt.initConfig({
  flipcss: {
    app: {
      files: {
        'css/main-rtl.css': 'css/main.css',
        'css/theme-rtl.css': 'css/theme.css'
      }
    }
  }
})

Flip multiple files to one file

In this example, multiple files are flipped and concatenated to a single file.

grunt.initConfig({
  flipcss: {
    app: {
      files: {
        'css/rtl.css': ['main.css', 'theme.css']
      }
    }
  }
})

Flip multiple file groups to multiple files

In this example, files in two directories are flipped.

grunt.initConfig({
  flipcss: {
    options: {},
    app: {
      files: [
        {
          expand: true,
          cwd: 'build/css',
          src: '*.css',
          dest: 'build/app/css'
        },
        {
          expand: true,
          cwd: 'build/theme',
          src: '*.css',
          dest: 'build/app/theme'
        }
      ]
    }
  }
})
