fontfinder 0.16.1

Package for finding and installing fonts for Unicode scripts.

fontfinder

Overview

fontfinder is a Python package for finding and installing fonts for Unicode scripts. It's useful when generating documents that must specify a font family and will be viewed across multiple platforms. For now, fontfinder mostly locates fonts in the Google Noto font collection.

Font enumeration and installation is currently supported on macOS (using CoreText) and Windows (using DirectWrite).

Most functionality is provided by instantiating the FontFinder class.

Examples

>>> from fontfinder import FontFinder
>>> ff = FontFinder()
>>> text = 'الشمس (رمزها: ☉) هي النجم المركزي للمجموعة الشمسية.' # From Arabic Wikipedia article about the Sun
>>> ff.analyse(text)
TextInfo(main_script='Arabic', script_variant='', emoji_count=1, script_count=Counter({'Arabic': 39, 'Common': 12}))
>>> known_families = ff.find_families(text) # Available font families for the given text
>>> print(known_families)
['Noto Kufi Arabic', 'Noto Naskh Arabic', 'Noto Naskh Arabic UI', 'Noto Sans Arabic']
>>> preferred_family = ff.find_family(text) # Selects a single preferred font family for the text
>>> print(preferred_family)
Noto Naskh Arabic
>>> print(ff.installed_families(preferred_family)) # The font family is not yet installed
[]
>>> family_fonts = ff.find_family_fonts(preferred_family)
>>> print([font_info.postscript_name for font_info in family_fonts]) # The individual fonts in the family
['NotoNaskhArabic-Bold', 'NotoNaskhArabic-Medium', 'NotoNaskhArabic-Regular', 'NotoNaskhArabic-SemiBold']
>>> from tempfile import TemporaryDirectory
>>> tempdir = TemporaryDirectory()
>>> fonts_for_download = ff.find_family_fonts_to_download(preferred_family) # The indiv fonts that can be downloaded
>>> fonts_for_install = ff.download_fonts(fonts_for_download, tempdir.name) # The downloaded fonts
>>> ff.install_fonts(fonts_for_install) # Actually install each individual font
>>> print(ff.installed_families(preferred_family)) # The font family is now installed
['Noto Naskh Arabic']
>>> ff.uninstall_fonts(fonts_for_install) # Uninstall each individual font
>>> print(ff.installed_families(preferred_family)) # The font family is once again not installed
[]
>>> tempdir.cleanup()
