Transform original string through style (TextTransform for Style) #93
Description
Activity
Way more difficult than I expected.
Transforming input string is quite easy for simpleStyle, but forStyleGroupis REALLY hard.
Having the chance to manipulate the string by changing its length messes up with ranges used to detect tags.- added a commit that references this issue
on Dec 20, 2019 It will be available inside the next release.
Custom Text Transforms
Sometimes you want to apply custom text transforms to your string; for example you may want to make some text with a given style uppercased with current locale.
In order to provide custom text transform inStyleinstances just set one or moreTextTransformto yourStyle's.textTransformsproperty:let allRedAndUppercaseStyle = Style({ $0.font = UIFont.boldSystemFont(ofSize: 16.0) $0.color = UIColor.red $0.textTransforms = [ .uppercaseWithLocale(Locale.current) ] }) let text = "test".set(style: allRedAndUppercaseStyle) // will become red and uppercased (TEST)
While
TextTransformis an enum with a predefined set of transform you can also provide your own function which have aStringas source and anotherStringas destination:let markdownBold = Style({ $0.font = UIFont.boldSystemFont(ofSize: 16.0) $0.color = UIColor.red $0.textTransforms = [ .custom({ return "**\($0)**" }) ] })
All text transforms are applied in the same ordered you set in
textTransformproperty.- changed the title

Sometimes it can be useful to have a
Stylecapable of transforming the string itself.Our current use case scenario is this one:
Style&instead of&is the most annoying example).UILabelAnother use case scenario is this #91
I believe something like this could work:
Or even something more complex like BonMot is doing here
I'll try to put together a PR.
