SFSymbols?

TPO

@mikael you could try FuzzyFinder in 10 lines of Python

Cheers,

pulbrich

I would go with @TPO ‘s idea, perfectly enough for the purpose.

@pulbrich, @TPO, thanks. Search now included, see the updated picture above.

Usability is not 100% - for some reason textfield.end_editing() does not hide the keyboard, at least on my phone.

pulbrich

@mikael Many, many thanks! Perfect now!

Same on my iPad mini 4 (iOS 13 + Pythonista beta)
There is a kind of flicking, I think that the keyboard is dismissed and then comes back.

FWIW:

from ui import *
from objc_util import *
uiimage=ObjCClass('UIImage')
v=Image.named('test:Lenna')
u=uiimage.systemImageNamed_('lessthan.circle')
v.objc_instance._setImageAsset_(u.imageAsset())

Leading underscore did the trick, iPadOS 13.1.3.
Maybe not the most future proof, but does the job...

@JonB As usual, you're the 🤴

mikael

@JonB, thanks. Intuitively this seems like it should be faster and more efficient than going via the PNG conversion.

But when I went to test the performance I ran into a couple of issues with the asset approach:

Resulting image size is dependent on the size of the original ui.Image created.
Both the original and ”asset-applied” images are retained in the ui.Image somehow, and for example ButtonItems do not really handle that well.

See below couple of example images. First one uses a too-large initializing picture (Lenna), the second too small one (triangle arrow icon), which you can see presented in the title area.

Break 1
Break 2

@mikael your module now crashes with

@cvp, yes, just noticed. iOS 14 must’ve changed it. Will take a look.

cvp

@mikael 900 added symbols in iOS 14 see here

mikael

@cvp, here’s the relevant code if you want to do a manual quick fix. Will push an update to PyPI soon.

    ...
    if point_size is not None:
        conf = conf.configurationByApplyingConfiguration_(
                UIImageSymbolConfiguration.configurationWithPointSize_(point_size))
    if weight is not None:
        conf = conf.configurationByApplyingConfiguration_(
            UIImageSymbolConfiguration.configurationWithWeight_(weight))
    if scale is not None:
        conf = conf.configurationByApplyingConfiguration_(
            UIImageSymbolConfiguration.configurationWithScale_(scale))
    objc_image = objc_image.imageByApplyingSymbolConfiguration_(conf)
    ...

mikael

@cvp, for the new symbols, I found a downloadable list of changes, but no list of new icons or an updated master list.

@mikael said:

Seems ok

cvp

@mikael dis you see? Even colored ones

7upser

If someone interested in a list of string, here we go

import plistlib
import io

vFilePath = '/System/Library/CoreServices/CoreGlyphs.bundle/symbol_order.plist'

with open(vFilePath, 'rb') as vFile:
	vFileObject = io.BytesIO(vFile.read())
vJsonSFSymbols = plistlib.load(vFileObject)

for vIndex, vJsonSFSymbol in enumerate(vJsonSFSymbols):
	print(str(vIndex).zfill(4), vJsonSFSymbol)

mikael

@7upser, excellent! I ran a quick comparison, and the plist list has all the symbols that the ”manual” list had, plus 162 additional symbols all ending in one of: ar, he, hi, ja, ko, zh or rtl, which I take to be additional language-based versions.

With this, when I have a moment, I can probably change the symbol browser to show whatever you have available in your iOS version, rather than relying on a manually updated list. What seems to be missing, though, is the marker for the symbols that Apple says must not be used outside their Apple context (like ”airpods”).

I'm missing the Categories for SF Symbols.
I think there are only Categories in the Mac App.
I found two older version and a Screenshot for the new Gaming Cat.
I add some cats for newer Symbols, but didn't finished.
This is what i have (with Pythonista Symbols and Emojis)

Icons.json

Names of restricted Symbols are here:
/System/Library/CoreServices/CoreGlyphs.bundle/symbol_restrictions.strings
(also a plist file)
