Apple/Mac FAQ: I want to add new fonts to my Mac, what is the Mac OS X (macOS) fonts folder?

Scary font ideas

I’m working on cover designs for my new “Functional Programming in Scala” book, and I want the words Functional Programming to be scary or intimidating. These are some different font ideas. The red fonts seem to get the “scary” point across well, though I suspect that some combinations of grays and white can also work.

All fonts available with XeTex and XeLaTeX

To generate a list of all fonts available available with XeTex and XeLaTeX, use this command at your Unix command line:

fc-list : family

How to get the default system font in a Java/Swing application

I haven’t tested this with other Java components, but if you want/need to get the “system font”, this code gets the default system font from a JEditorPane component:

val outputArea = new JEditorPane
val fontFamily = outputArea.getFont.getFamily

That code is written in Scala, but as you can see, it converts easily to Java. On Mac OS X 10.10, fontFamily ends up being “Lucida Grande”.
