Support for alt text on images posted to Twitter (blocked on mf2py)

[miklb]

It seems that it is doable with the Twitter REST API to pass alt text for images

Not 100% sure how to do so with Bridgy, unless bridgy can parse the alt attribute from the image with a u-photo or u-featured class. Then it would be pretty straight forward I would guess.

this is currently blocked on mf2py supporting img alt text explicitly, microformats/mf2py#83, based on microformats/microformats2-parsing#2.

(also, for my own notes, i'm tentatively planning to serialize HTML alt into AS1 displayName. alternative was summary.)

[snarfed]

this is deployed! still needs more testing and bug fixes - eg i need to ellipsize at 420 chars, and i think it doesn't work with multiple photos right now - but feel free to try it!

[snarfed]

fixed both of those issues.

• alt text: screen shot of aperture and my website

@snarfed I'm not sure if this may have broken again, but looking at this tweet in Granary, I don't see the alt tag returned, unless I'm doing something wrong?

[snarfed]

ah, i only implemented this for publishing, not consuming. i take it you're interested in the consuming side in granary? looks doable! interested in tackling it? 😁

[jamietanna]

Sorry yep, I'm only looking for the consuming side as I've seen that Bridgy does publish the alt tags to Twitter.

I wasn't looking where I was and thought this issue was on Granary - sorry! I'll raise an issue for it, not sure if I'll get round to it soon, but it'll at least be there for someone else to

@jamietanna Perhaps helpful to crosslink it here when you open the ticket.

@Ryuno-Ki snarfed/granary#183 is the issue, of which snarfed has already implemented a fix 🙌🏼
