pyglass: Preview Mac OS X Documents

pyglass is a python wrapper around Apple's QuickLook to extract preview images from common filetypes.

Additionally, pyglass wraps around SketchTool to generate previews from Sketch files.

Usage

Basic Previews

>>> import pyglass
>>> previews = pyglass.preview('design_v1.sketch')
>>> previews
 ['/var/folders/fq/xtn_qh1x6c3drpp3ycytx1fr0000gn/T/pyglassY92Xqs.png',
 '/var/folders/fq/xtn_qh1x6c3drpp3ycytx1fr0000gn/T/pyglassZ34Jab.png']

Each preview returned in the list is a PNG, one for each page in the source document.

Sketch

Pages

To get a flat list, use sketch.pages. Note that slices and artboards lists within each page are not populated automatically with this command. Use sketch.list_artboards and sketch.list_slices respectively if you're interested in artboard and slice data.

>>> pyglass.sketch.pages('/Users/Vayu/Development/src/pyglass/tests/data/sketch/pages.sketch')
[<Page:
  '<Page (
      id="C10E136D-6E3D-40C9-AA6C-67C456893C6D",
      name="Something",
      bounds=<Bounds (x=-75.0, y=-128.0, width=541.0, height=399.0)>,
      slices=[],
      artboards=[]
   )>'
 >,
<Page:
  '<Page (
      id="AB21474C-3F41-4531-8433-9E01140E08EC",
      name="Another one",
      bounds=<Bounds (x=-66.0, y=-31.0, width=587.0, height=369.0)>,
      slices=[],
      artboards=[]
   )>'
 >,
<Page:
  '<Page (
    id="7BEAECDA-21FF-4245-9758-D94A3FDAA9A8",
    name="A third one",
    bounds=<Bounds (x=-99.0, y=-269.0, width=572.0, height=312.0)>,
    slices=[],
    artboards=[]
  )>'
>]

Artboards

To get a flat list, use sketch.artboards

>>> pyglass.sketch.artboards('/Users/Vayu/Development/src/pyglass/tests/data/sketch/artboards.sketch')
[<Artboard: '<Artboard (
                id="38BADD7D-C452-4DFD-9054-7939A23902C1",
                name="Artboard 1",
                rect=<Rect (x=-101.0, y=-557.0, width=640.0, height=1136.0)>)
              >'>,
<Artboard: '<Artboard (
                id="BFFAD951-2678-4C55-85CB-0B2130BD0392",
                name="Artboard 2",
                rect=<Rect (x=639.0, y=-557.0, width=640.0, height=1136.0)>)
            >'>
]

To get the entire hierarchy, use sketch.list_artboards

>>> pyglass.sketch.list_artboards('/Users/Vayu/Development/src/pyglass/tests/data/sketch/artboards.sketch')
[<Page:
  '<Page (
    id="C10E136D-6E3D-40C9-AA6C-67C456893C6D",
    name="Something",
    bounds=<Bounds (x=-131.0, y=-587.0, width=1440.0, height=1196.0)>,
    slices=[],
    artboards=[
      <Artboard: \'<Artboard (
                      id="38BADD7D-C452-4DFD-9054-7939A23902C1",
                      name="Artboard 1",
                      rect=<Rect (x=-101.0, y=-557.0, width=640.0, height=1136.0)>
                    )>\'>,
      <Artboard: \'<Artboard (
                      id="BFFAD951-2678-4C55-85CB-0B2130BD0392",
                      name="Artboard 2",
                      rect=<Rect (x=639.0, y=-557.0, width=640.0, height=1136.0)>
                    )>\'>
    ]
  )>
'>]
