How to Find the Full Path to a Font from its Display Name on a Mac using Python

If you’re working on a design project that requires you to identify specific fonts from their display names, you might face the challenge of pinning down the actual path to those fonts on your Mac. This often comes into play when you’re using Photoshop’s JavaScript API within a Python environment, and you need to bridge the gap between the font name you have and its physical file on your disk. Let’s explore how you can tackle this problem effectively.

Understanding the Problem

In graphic design and digital content creation, fonts play a crucial role. When working in Photoshop, you might retrieve a font name via the JavaScript API. However, to streamline your workflow, you might need to locate the physical font file associated with this name on your Mac’s filesystem. The task at hand is to discover a straightforward method to achieve this, preferably using Python or relevant APIs.

Approaches to Consider

As you look for solutions, here are the possible routes you could take:

  • Using Photoshop JavaScript Functions
  • Leveraging Python Functions
  • Calling macOS APIs via Python

The Solution: Locating the Font Path

Key Method

The most effective method currently available is utilizing a function from the ApplicationServices framework on macOS. Unfortunately, due to the lack of bridge support files, it is difficult to access this directly from Python. However, with the help of ctypes, you can interact with this framework directly.

Step-by-Step Explanation

  1. Accessing the Font Reference

    • You need to first look up the ATSFontRef for the font you’re interested in. This can be done either from the font name or display name.

  2. Using ATSFontGetFileReference

    • After you have the ATSFontRef, you can use the ATSFontGetFileReference function to obtain the file reference for that font.

Python Implementation

Here’s a simplified outline of how you can implement this in Python with a focus on using ctypes:

import ctypes
from ctypes import c_void_p, c_char_p

# Load the ApplicationServices framework
ApplicationServices = ctypes.cdll.LoadLibrary('/System/Library/Frameworks/ApplicationServices.framework/ApplicationServices')

# Define the function signatures
# Example: Define any necessary function signatures here based on the ATSFontRef

# ... Your additional code to look up ATSFontRef goes here

Points to Note

  • As of macOS 10.5, Cocoa offers limited support for obtaining font locations. Therefore, utilizing the ApplicationServices framework is often your best bet.

  • Be aware of deprecated APIs and always check for updated documentation, as macOS evolves over time.

Conclusion

In conclusion, retrieving the full path of a font from its display name on a Mac involves using a combination of Photoshop’s JavaScript API and macOS frameworks accessed through Python. While there are certain limitations, especially regarding support, using ctypes with the ApplicationServices framework can provide a way to achieve your goal.

If you follow the steps outlined above, you will be better equipped to manage fonts effectively in your design projects.

By integrating these steps into your workflow, you can simplify your process of managing fonts, thereby enhancing your efficiency and creative output.
