I’m trying to generate a full range of files but I’m stuck on woff2. Am I missing something for the argument? The file that gets generated appears to be a woff as it is the same size as a woff.
When generating woff/2 you don’t have control over the filename. I believe it generates automatically from the family name. Is it possible to adjust for this?
ex.
import os
from robofab.interface.all.dialogs import GetFolder
fileFolder = GetFolder("Pick a directory...")
folderPath = '~/Desktop/TEMP_FONT_INSTANCES'
folderPathRelative = os.path.expanduser(folderPath)
if not os.path.exists(folderPathRelative):
os.makedirs(folderPathRelative)
web_path = folderPath + "/web"
web_pathRelative = os.path.expanduser(web_path)
if not os.path.exists(web_pathRelative):
os.makedirs(web_pathRelative)
fileFolder = os.path.expanduser(fileFolder)
fileNames = os.listdir(fileFolder)
OTF_AutoHint = True
TTF_AutoHint = True
RemoveOverlap = True
UseSubroutines = True
UseProductionNames = True
for fileName in fileNames:
if os.path.splitext(fileName)[1] == ".glyphs":
for instance in font.instances:
print "== Exporting WOFF --> " + web_path + "/file_name.woff"
instance.customParameters["Webfont Formats"] = "woff"
instance.generate(Format = "TTF", FontPath = os.path.expanduser(web_path + "/file_name.woff"), AutoHint = TTF_AutoHint, RemoveOverlap = RemoveOverlap, UseSubroutines = UseSubroutines, UseProductionNames = UseProductionNames)
print
Secondly — my script is causing autosaves on the fonts I generate. Is it possible to close/remove them?
your scrip is missing the copy post from my snippet. That is specifically added to prevent changing the original document.
And there is a “fileName” parameter in the instances (check the actual spelling, I’m not at the Mac right now).
Thank you for all your help.
I can’t find in the API documentation a list of possible custom parameters.
Does this exist, can I generate it? print help(instanceFont.instances[0].customParameters)? How do I check the actual spelling?
To confirm
Copying the instance removes autosave files?
I can define the file name via customParemeters[“File Name or something”] instead of the FontPath?
import os
from robofab.interface.all.dialogs import GetFolder
fileFolder = GetFolder("Pick a directory...")
folderPath = '~/Desktop/TEMP_FONT_INSTANCES'
folderPathRelative = os.path.expanduser(folderPath)
if not os.path.exists(folderPathRelative):
os.makedirs(folderPathRelative)
web_path = folderPath + "/web"
web_pathRelative = os.path.expanduser(web_path)
if not os.path.exists(web_pathRelative):
os.makedirs(web_pathRelative)
fileFolder = os.path.expanduser(fileFolder)
fileNames = os.listdir(fileFolder)
for fileName in fileNames:
if os.path.splitext(fileName)[1] == ".glyphs":
font = GSFont(os.path.join(fileFolder, fileName))
saveFileName = font.filepath.lastPathComponent().replace(".ufo", "").replace(".glyphs", "").replace(".vfb", "")
for instance in font.instances:
print "== Exporting WOFF --> " + web_path + "/"
instanceFont = instance.interpolatedFont # Copying the instance remove autosave files
instanceFont.instances[0].customParameters["Webfont Formats"] = "woff2"
instanceFont.instances[0].customParameters["File Name"] = saveFileName + ".woff2" # File Name is defined here
instanceFont.instances[0].generate(Format = "TTF", FontPath = os.path.expanduser(web_path))
print
The custom parameters are not documented in the python docu but in the appendix of the Handbook. Or just see what is available in the master/instance settings.
fileName string Name for the font file, without the dot suffix, i.e.,
without ‘.otf’, etc. Gives you the chance to export two versions
of the same font style name without the second file overwriting
the first one
After the last update the script I’ve been working with has stopped working.
The script shown above now errs:
Traceback (most recent call last):
File "<string>", line 24, in <module>
File "GlyphsApp/GlyphsApp/__init__.py", line 3634, in <lambda>
File "GlyphsApp/GlyphsApp/__init__.py", line 3632, in Instance_FontObject
TypeError: 'NSKVONotifying_GSFont' object is not callable

Any news on exporting Webfonts like that? I got an rather old script which doesn’t export the webfonts anymore. It did work way back.
When I run this code from Quinn posted above but adding a traceback, I get this:
Traceback (most recent call last):
File "<string>", line 28, in <module>
File "GlyphsApp/GlyphsApp/__init__.py", line 4254, in __Instance_Export__
ValueError: NSInvalidArgumentException - -[NSTaggedPointerString count]: unrecognized selector sent to instance 0xa4874c57d14229a5
I tried to export webfonts from Glyphs UI and Glyphs crashed, when I had a CP “Webfont Formats”
(for testing. I sent the report).
When I have the CP [“Webfont Formats” = woff2] in one instance (again for testing) and want to export Webfonts from GUI (Setting to WOFF and WOFF2), I get these errors: There was a problem converting the PostScript source font. (Light)
and The file “XYZ-Thin.woff2” couldn’t be opened because there is no such file.
