Kitty shows font using oblique face vs. book face

I should also specify that this is on OS X using the Core Text API; I'm on e34f74f.

Hmm, I dont have an awful lot of experience with CoreText but I know of no reason why it should prefer the oblique to the regular face, see line 48 of core_text.m where the font descriptor is created, the only traits specified are bold, italic and monospace, bold and italic should give the bold and italic variants and when they are off it should give the normal variant. And in https://developer.apple.com/reference/coretext/ctfontsymbolictraits?language=objc I see no mention of oblique at all. So I'm not sure what else to do here. You can display the full name of the font CoreText resolves to, using the following command:

/Users/Shared/buildbot/sw/sw/bin/python3 /path/to/kitty -c "from kitty.fonts.core_text import *; set_font_family('DejaVuSansMonoForPowerline', 12, True); f=main_font[(False, False)]; print(f.family_name, f.full_name)"

sorry for the slow response @kovidgoyal!

here's what you asked for (I updated to current git and rebuilt before running this):

$ /Users/Shared/buildbot/sw/sw/bin/python3 . -c "from kitty.fonts.core_text import *; set_font_family('DejaVuSansMonoForPowerline Nerd Font', 12, True); f=main_font[(False, False)]; print(f.family_name, f.full_name)"
[glfw error]: The GLFW library is not initialized
DejaVuSansMonoForPowerline Nerd Font
DejaVu Sans Mono Oblique for Powerline Nerd Font Complete Mono

$ /Users/Shared/buildbot/sw/sw/bin/python3 . -c "from kitty.fonts.core_text import *; set_font_family('DejaVuSansMonoForPowerline Nerd Font Book', 12, True); f=main_font[(False, False)]; print(f.family_name, f.full_name)"
[glfw error]: The GLFW library is not initialized

Helvetica

$ /Users/Shared/buildbot/sw/sw/bin/python3 . -c "from kitty.fonts.core_text import *; set_font_family('DejaVuSansMonoForPowerlineNerdFontCompleteMono-Book', 12, True); f=main_font[(False, False)]; print(f.family_name, f.full_name)"
[glfw error]: The GLFW library is not initialized
Helvetica

Notice that a family name of DejaVuSansMonoForPowerline Nerd Font returns the Oblique face (not the Book one).

Probably, the font name you need is something like

DejaVu Sans Mono Book for Powerline Nerd Font Complete Mono
or
DejaVu Sans Mono Regular for Powerline Nerd Font Complete Mono
or
DejaVu Sans Mono for Powerline Nerd Font Complete Mono
