Re: [g-a-devel] Keeping/removing AccessibleText get by Sentence [Fwd: Re: [Accessibility-ia2] Suggest remove IA2_TEXT_BOUNDARY_SENTENCE]

I think SENTENCE support should be removed, and the rest kept. The rest are usually already implemented in some form by the app.

Sentence can be implemented by the AT if it really needs it. I don't want to have to deal with the i18n issues here. Also the AT needs consistency and every app will do this differently.

Hi guys,

In addition to the discussion about state deprecations, I'd like to give another kick to the apple cart - keeping/removing some of the text range constants. I put the letter/word/line/sentence stuff in in the first place, thinking it'd be useful for several AT use cases and trusting that the Java parsing support for those chunks would do the right thing.

Alas, as Harald points out supporting this generally (especially sentence) is a right pain. And I have a feeling that screen readers aren't using this API. So, while we are in a deprecating mood, perhaps we should deprecate this too?
I am not in favor of this removal. It's actually much easier to implement in most cases than "LINE", and we need to keep the old ones around for back-compat guarantees anyhow.

I think a good case can be made for retaining this for 'talking book', page-reading, and similar use cases (i.e. meta clipboard apps that cuts one sentence, etc.)

I don't believe this is something the AT wants to have the app support
for just accessibility, because the support will end up being incorrect
or very different between implementations.
I agree to this, I'd love to see Sentence go. It's not only a nightmare to implement, it can also lead to obscure bugs with languages that don't have a concept of "sentence".
