Modify Python Script to Batch Convert all "WOFF" Files in Directory

I have been using a great open-source python script by GitHub user @hanikesn (see below) that converts a single WOFF file back into OTF format via command line (Terminal on Mac OS X).

As it is now, I drag-and-drop the script to Terminal, then drag-and-drop a WOFF file to Terminal, press Enter, and the script creates an OTF in the same directory. The script can be invoked manually, but I find it much easier and much faster to drag-and-drop. However as a typographer, I work with large font-families, some of them have over 100 styles each, so I need a batch conversion tool. I know there are some tools online, but these usually have a size limit unless you pay for the service, and the results are never as consistent as this script. Besides, I would like to have an offline tool.

I would like to modify it to run on a directory (folder of WOFFs) rather than a single file. Ideally I would like to drag-and-drop the script into terminal, and then drag-and-drop a folder. The script should only attempt to convert files with the .woff extension.

When I asked the creator of the script, he said "This can easily be done with a simple one line shell script:

for file in *.woff; do woff2otf.py $file; done

However I don't know how to implement this. I am not a programmer, but I've had to work with some basic python scripting in my typography projects. So, please explain it to me like I'm 5.

woff2otf.py

You are using zsh, aren't you? so to loop on your WOFF files you could to do

for f in *.woff ; /complete/path/to/your/script.py $f

If you want create an Drag&drop app, you could:

  • open the Automator.app
  • select "Application"
  • in the left-side Library find the Filter Finder Items action
  • drag it into the right
  • add the extenstion is woff condition
  • in the Library find the Run Shell Script action
  • change the Pass input popup to as arguments
  • drag&drop the your woff2otf.py into the place of the echo (you will get it's full path name)
  • save the app somewhere as woff2otf.app
  • congratz - you're done with your 1st OS X application. :)

Just drag the woff files into the application icon and it should convert them. I can't test it, because i havent installed python3.

The final app should be as in the following screenshot:

enter image description here

EDIT: If your python3 command isn't in the standard command search $PATH, you must change the line:

  • /path/to/the/woff2otf.py "$f" to
  • /path/to/your/python3 /path/to/the/woff2otf.py "$f"

I installed python3 using anyenv - e.g. it wont help you. Therefore my python3 is:

$ type python3
python3 is /opt/anyenv/envs/pyenv/shims/python3

so the line in the shell script (for me) looks like:

/opt/anyenv/envs/pyenv/shims/python3 ~/bin/woff2otf.py "$f"

But, your installation is surely different.
