How to get/set attributes of attributedString (from Text Layer)?

[GoranW (Göran Wallgren)]

Hi! I’m on Sketch 2025.2.1 (Barcelona) and I’m trying write plugin code for getting and setting the text in TextLayers, for localization purposes. I’ve got that working fine, but now I also need to get/set the internal styling (mainly bold/italic and color) of individual text-ranges inside a string.

I’ve found out that string-internal styling is stored as attributedString with attributes in the Sketch (JSON) Open File Format, but I’m looking for a way to access this data from JavaScript code.

A sketch.Types.Text layer does not seem to have direct access to this data. But I can use layer.sketchObject to get the underlying native MSTextLayer object, and from that I can use .attributedString() to get the MSAttributedText object, which also gives me the text-string via its method .string().

However, then I’m stuck, since from there I don’t know how to access the array of stringAttribute (?) objects which I suppose contain attributes of type MSAttributedStringFontAttribute and MSAttributedStringFontColorAttribute etc.

Any help would be appreciated.

Never mind, I was able to solve it by using “introspection” methods on the Mocha class.

I can access the text-styling ranges this way, from a Text component (layer) :

msTextLayer = textComponent.sketchObject // MSTextLayer
msAttribStr = msTextLayer.attributedString() // MSAttributedString
strAttribs = msAttribStr.attributedStringAttributes() // MSAttributedStringAttribute
attribs = Array.from(strAttribs)

attr = attribs[0]
r = attr.range()
d = attr.attributeDictionary()
//k = d.allKeys()

c = d["MSAttributedStringColorAttribute"]

f = d["MSAttributedStringFontAttribute"]
fd = f.fontAttributes()
//fk = fd.allKeys()
fn = fd["NSFontNameAttribute"]
