Thank you.

I added it to the wrapper and the docu (both will be online soon).

I’m trying to access value with this code :

font = Glyphs.font
master = font.selectedFontMaster
print(master.numberValueForName_("newNumber").value)

It return me

<native-selector value of <GSInfoValue 0x60000467d680> 0>

What I’m doing wrong ?

Add a () after the value, like this: numberValueForName_(“name”).value()

Which is the method to add a Number Value to Font ?
I tried all method with GSFont, but I didn’t succeed.

9

Number values are set on masters.

10

I also tried all GSFontMaster Method…

11

I see, the wrapper code is not yet in the latest shipping version.

Here is what you can do in the meantime:

someMaster.setNumberValueValue_forName_(15, 'SomeName')

Got a couple questions on this same topic.

  1. How to access the Name and Value of each Number Value in a Master?
font = Glyphs.font
master = font.selectedFontMaster
print (master.numbers())

prints out something like this

(
    "<GSInfoValue 0x600005be3120> 70",
    "<GSInfoValue 0x600039b31920> 100",
)
  1. I am able to set number values but do not see them updating in the actually Master tab menu UI. Is there another way to achieve this or force the UI to update?
# Access the current font
font = Glyphs.font

font.disableUpdateInterface()
# Iterate through all font masters
for master in font.masters:
    # Check if the master's name is in our predefined dictionary
    if master.name in master_values:
        # Iterate through each name-value pair for this master
        for name, value in master_values[master.name].items():
            # Set the number value for this name
            master.setNumberValueValue_forName_(value, name)
            print(f"Set {name} to {value} for {master.name}")
    else:
        print(f"No predefined values for {master.name}")
font.enableUpdateInterface()

Any update on this? Is there a method to output the name value of the number values?

The names is stored in font.numbers (similar to font.metrics and font.stems). You can either do:

master = Font.masters[0]
for number in Font.numbers:
	print(number.name)  # e.g. "My Number"
	numberValue = master.numbers[number.id]
	print(numberValue)  # e.g. 123
	infoValue = master.numberValueForId_(number.id)
	print(infoValue)  # e.g <GSInfoValue 0x600002d49ad0> 123

or

master = Font.masters[0]
for metricId in master.numberValues():
	infoValue = master.numberValues()[metricId]
	print(infoValue)  # e.g <GSInfoValue 0x600002d49ad0> 123
	number = infoValue.metric()
	print(number)  # e.g. <GSMetric 0x6000029f76c0> My Number (22F234ED-8128-4819-8E02-3BF3766A8140)
	print(number.name)  # e.g. "My Number"

Thanks @GeorgSeifert

Is the value updating method the same as Florian described in his earlier message? I.e.:

someMaster.setNumberValueValue_forName_(15, 'SomeName')

Thanks in advance!

16 
master.numbers["SomeName"] = 15

I just saw that the UI is not properly updating. I’ll need to have a look.

I think this is what @gor.jious was asking in his last post.

Thanks again!

Is the first approach more recommended?

The first approach works fine.
The second approach – after opening the font – gives an error:

<GSInfoValue 0x600000cdf420> 14
None
Traceback (most recent call last):
  File "<macro panel>", line 7
AttributeError: 'NoneType' object has no attribute 'name'

However, after opening and closing Font Info → Masters, it starts working as expected:

<GSInfoValue 0x600003009740> 14
<GSMetric 0x6000024d3000> myMetric1 (CCF11B2C-B0A8-4E6F-8606-536BE0F5A166)
