Unable to patch fonts on Apple silicon #662
Description
Hello,
I'm trying to patch a font but despite having FontForge installed locally, which is said to be the only prerequisite in the docs, attempting to run the Python script resulted in:
» /opt/font-patcher.py
Nerd Fonts: FontForge module is probably not installed. [See: http://designwithfontforge.com/en-US/Installing_Fontforge.html]
So I tried it this way:
» fontforge -script /opt/font-patcher.py RecMonoSemicasual-Bold-1.078.ttf

The requested file, original-source.otf, does not exist
Traceback (most recent call last):
File "/opt/font-patcher.py", line 929, in <module>
main()
File "/opt/font-patcher.py", line 924, in main
patcher.patch()
File "/opt/font-patcher.py", line 88, in patch
symfont = fontforge.open(self.args.glyphdir + patch['Filename'])
OSError: Open failed
So then I tried it this way:
» docker run -v unpatched:/in -v patched:/out nerdfonts/patcher -c
WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested
And finally, I tried it this way:
» docker run --platform linux/amd64 --rm -v unpatched:/in -v patched:/out nerdfonts/patcher -c
...which simply fails to launch, whereas Docker notes "Attempts to run Intel-based containers on Apple Silicon machines under emulation can crash as qemu sometimes fails to run the container." Docker's recommended remedy is "encouraging container authors to produce arm64, or multi-arch, versions of their containers." So I'm here to encourage you to please build a multi-arch version of the Docker image so that I may patch my fonts in peace.
Thank you!
