Glyphs.app Python Scripting API Documentation¶
This is the documentation for the Python Scripting API for Glyphs.app (glyphsapp.com)
About this Document¶
This document covers all methods that are implemented in the Python wrapper. There are many more functions and objects available via the PyObjC bridge. For more details, please have a look at the Core part of the documentation.
Changes in the API¶
These changes could possibly break your code, so you need to keep track of them. Please see GSApplication.versionNumber for how to check for the app version in your code. Really, read it. There’s a catch.
GSApplication¶
The mothership. Everything starts here.

class
GSApplication¶ Properties
Functions
Properties
-
currentDocument¶ The active
GSDocumentobject or None.- Type:
# topmost open document document = Glyphs.currentDocument
-
documents¶ An array of open
GSDocumentobjects.- Type:
list
-
fonts¶ Be aware that the order is defined by last used font. Append and extend generally don’t insert at the end of the list.
- Type:
list
# access all open fonts for font in Glyphs.fonts: print(font.familyName) # add a font font = GSFont() font.familyName = "My New Font" Glyphs.fonts.append(font)
-
reporters¶ List of available reporter plug-ins (same as bottom section in the ‘View’ menu). These are the actual objects. You can get hold of their names using object.__class__.__name__.
Also see
GSApplication.activateReporter()andGSApplication.deactivateReporter()methods below to activate/deactivate them.- Type:
list
# List of all reporter plug-ins print(Glyphs.reporters) # Individual plug-in class names for reporter in Glyphs.reporters: print(reporter.__class__.__name__) # Activate a plugin Glyphs.activateReporter(Glyphs.reporters[0]) # by object Glyphs.activateReporter('GlyphsMasterCompatibility') # by class name
-
activeReporters¶ List of activated reporter plug-ins.
- Type:
list
# Activate a plugin Glyphs.activateReporter(Glyphs.reporters[0]) # list of currently active reporter plug-ins activeReporters = Glyphs.activeReporters
-
filters¶ List of available filters (same as ‘Filter’ menu). These are the actual objects.
Below sample code shows how to get hold of a particular filter and use it. You invoke it using the processFont_withArguments_() function for old plugins, or the filter() function for newer plugins. As arguments you use the list obtained by clicking on ‘Copy Custom Parameter’ button in the filter’s dialog (gear icon) and convert it to a list. In the include option you can supply a comma-separated list of glyph names.
- Type:
list
# Helper function to get filter by its class name def filterForName(name): for filter in Glyphs.filters: if filter.__class__.__name__ == name: return filter # Get the filter offsetCurveFilter = filterForName('GlyphsFilterOffsetCurve') # Run the filter (old plugins) # The arguments came from the 'Copy Custom Parameter' as: # Filter = "GlyphsFilterOffsetCurve;10;10;1;0.5;" offsetCurveFilter.processFont_withArguments_(font, ['GlyphsFilterOffsetCurve', '10', '10', '1', '0.5', 'include:%s' % glyph.name]) # If the plugin were a new filter, the same call would look like this: # (run on a specific layer, not the first layer glyphs in the include-list) # The arguments list is a dictionary with either incrementing integers as keys or names (as per 'Copy Custom Parameter' list) offsetCurveFilter.filter(layer, False, {0: 10, 1: 10, 2: 1, 3: 0.5})
New in version After: 2.4.2
-

- Type:
bool
if Glyphs.boolDefaults["com.MyName.foo.bar"]: print('"com.MyName.foo.bar" is set')
-

int
-
handleSize¶ Size of Bezier handles in Glyph Edit view. Possible value are 0–2. Corresponds to the ‘Handle size’ setting from the Preferences.
To use the handle size for drawing in reporter plugins, you need to convert the handle size to a point size, and divide by the view’s scale factor. See example below.
- Type:
int
# Calculate handle size handSizeInPoints = 5 + Glyphs.handleSize * 2.5 # (= 5.0 or 7.5 or 10.0) scaleCorrectedHandleSize = handSizeInPoints / Glyphs.font.currentTab.scale # Draw point in size of handles point = NSPoint(100, 100) NSColor.redColor.set() rect = NSRect((point.x - scaleCorrectedHandleSize * 0.5, point.y - scaleCorrectedHandleSize * 0.5), (scaleCorrectedHandleSize, scaleCorrectedHandleSize)) bezierPath = NSBezierPath.bezierPathWithOvalInRect_(rect) bezierPath.fill()
-
versionString¶ String containing Glyph.app’s version number. May contain letters also, like ‘2.3b’. To check for a specific version, use
Glyphs.versionNumberbelow.- Type:
string
-
versionNumber¶ Glyph.app’s version number. Use this to check for version in your code.
- Type:
float
-
buildNumber¶ Glyph.app’s build number.
Especially if you’re using preview builds, this number may be more important to you than the version number. The build number increases with every released build and is the most significant evidence of new Glyphs versions, while the version number is set arbitrarily and stays the same until the next stable release.
- Type:
float
Add menu items to Glyphs’ main menus.
Following constants for accessing the menus are defined:
APP_MENU,FILE_MENU,EDIT_MENU,GLYPH_MENU,PATH_MENU,FILTER_MENU,VIEW_MENU,SCRIPT_MENU,WINDOW_MENU,HELP_MENUdef doStuff(sender): # do stuff newMenuItem = NSMenuItem('My menu title', doStuff) Glyphs.menu[EDIT_MENU].append(newMenuItem)

-
addCallback(function, hook)¶ Add a user-defined function to the glyph window’s drawing operations, in the foreground and background for the active glyph as well as in the inactive glyphs.
The function names are used to add/remove the functions to the hooks, so make sure to use unique function names.
Your function needs to accept two values: layer which will contain the respective
GSLayerobject of the layer we’re dealing with and info which is a dictionary and contains the value Scale (for the moment).For the defined keys see Callback Keys
def drawGlyphIntoBackground(layer, info): # Due to internal Glyphs.app structure, we need to catch and print exceptions # of these callback functions with try/except like so: try: # Your drawing code here NSColor.redColor().set() layer.bezierPath.fill() # Error. Print exception. except: import traceback print(traceback.format_exc()) # add your function to the hook Glyphs.addCallback(drawGlyphIntoBackground, DRAWBACKGROUND)
-
removeCallback(function)¶ Remove the function you’ve previously added.
# remove your function from the hook Glyphs.removeCallback(drawGlyphIntoBackground)
-

-
localize(localization)¶ Return a string in the language of Glyphs.app’s UI locale, which must be supplied as a dictionary using language codes as keys.
The argument is a dictionary in the languageCode: translatedString format.
You don’t need to supply strings in all languages that the Glyphs.app UI supports. A subset will do. Just make sure that you add at least an English string to default to next to all your other translated strings. Also don’t forget to mark strings as unicode strings (
'öäüß') when they contain non-ASCII content for proper encoding, and add a # encoding: utf-8 to the top of all your .py files.Tip: You can find Glyphs’ localized languages here
Glyphs.defaults["AppleLanguages"].print(Glyphs.localize({ 'en': 'Hello World', 'de': 'Hallöle Welt', 'fr': 'Bonjour tout le monde', 'es': 'Hola Mundo', })) # Given that your Mac’s system language is set to German # and Glyphs.app UI is set to use localization (change in app settings), # it will print: >> Hallöle Welt

Glyphs.activateReporter('GlyphsMasterCompatibility')
-
deactivateReporter(reporter)¶ Deactivate a reporter plug-in by its object (see Glyphs.reporters) or class name.
Glyphs.deactivateReporter('GlyphsMasterCompatibility')
-
GSDocument¶
The document class
GSFont¶
Implementation of the font object. This object is host to the masters used for interpolation. Even when no interpolation is involved, for the sake of object model consistency there will still be one master and one instance representing a single font.
Also, the glyphs are attached to the Font object right here, not one level down to the masters. The different masters’ glyphs are available as layers attached to the glyph objects which are attached here.

enableUpdateInterface()¶ This re-enables the interface update. Only makes sense to call if you have disabled it earlier.
