I would like to put a contiguous overline over a series of c

Question

I would like to put a contiguous overline over a series of characters in a Text composable like you would notate a repeating decimal The only options for `TextDecoration` appear to be `LineThrough` `Underline` and `None` I tried putting combining overline unicode characters in the text but it puts an overline over each character not one contiguous overline across all the characters Is there a way to do this in Compose

Thinking about this a little more `TextDecoration` was probably not the appropriate place to look to solve this because I d want to be able to overbar a substring of the text Perhaps then this is not a Compose specific question

Siyamed · Answer

I didnt understand why TeztDecoration doesnt work dor this case

Siyamed · Answer

Are you using AnnotatedString or factory function of it to set the TextDecoration on the substring

Siyamed · Answer

Currently the factory function is ``` buildAnnotatedString append myString setSpanStyle 3 5 SpanStyle textDecoration = TextDecoration Underline ``` I am on mobile so the function signature might not be accurate but they should be similar

Rick Regan · Answer

My comment about TextDecoration was imagining a new overline option but that that would not help in the Text composable because it would overline the whole string But I have not used AnnotatedString before so I will look into it and let you know

Rick Regan · Answer

I found a code example for AnnotatedString which I was able to modify to use TextDecoration Underline to underline a subset of a string so that s a good start thanks I also applied the combining overline to a substring and that worked in that it put a bar over each character To get the vinculum for repeating decimals I would need a contiguous overline Is that something TextDecoration could support for Compose

Siyamed · Answer

Decoration overline is a planned feature but since it was not natively supported by android we deprioritized it We want to add it but there would be a considerable time gap

If there is an open feature request please point me to it so I could star it and comment on it Thanks
