## About Font-Discovery This is a library to find system font files. It works on systems with DirectWrite (Windows), CoreText (macOS, iOS), and FontConfig (Linux, BSD). It does not have any foreign dependencies that aren't already directly available on the system. ## How To You can list all fonts by using ``list-fonts``, or find a specific font using ``find-font``. Both of these functions take a number of arguments to query for fonts with specific properties (``family``, ``slant``, ``weight``, ``spacing``, ``stretch``). Both of them return ``font`` instances, from which you can query the precise properties, as well as their font file location with ``file``.

Uninitializes the library.
This will shut down foreign libraries and deallocate cache memory.
Returns T if it did so.
It will not close the foreign libraries that were opened by INIT.
It is safe to call this function multiple times.
See INIT
Attempts to find a font with specifications that match the query as close as possible.
Returns a FONT instance, or NIL if no match can be found.
Note that on some systems the returned font may not be an exact
match, but rather a closest approximation.
For the possible values of the arguments, see the FONT class and its
reader functions.
Doing this will automatically call INIT.
See LIST-FONTS
See INIT
See FONT
Initializes the library for use.
This will load foreign libraries and set up internal state if
necessary. Returns T if it did so.
It is safe to call this function multiple times.
See REFRESH
See DEINIT
Returns a list of fonts with specifications that match the query.
Returns a list of FONT instances that match the query.
For the possible values of the arguments, see the FONT class and its
reader functions.
Doing this will automatically call INIT.
See FIND-FONT
See INIT
See FONT
Refreshes the font cache.
This should cause new system fonts to be recognised. You should call
this function whenever you think the list of system fonts might have
changed. Returns T if the cache was updated.
Doing this will automatically call INIT.
