Image alt text?

cfristrom · January 13, 2023, 4:50pm

I have been posting photos to my hosted Micro.blog account from the iOS Sunlit app, and adding an “Accessibility Description” to each photo before posting. But when I look at the post source the img alt tag is an empty string.

For example, take a look at Elegant Newt

If I edit the post using the Micro.blog web interface and add a non-empty alt tag string, the post works as expected, for example Elegant Newt

Why is the description not being included in the markup? Am I just not understanding how this works?

I have also had this issue for some time now. This must be a bug.

This is a bug in Sunlit. It works correctly in all the other apps, but I think we need to do a bug fix update for Sunlit.

I cloned the Sunlit repo and fixed the bug. I would like to create a PR but I’m not sure what branch to base my fix on. Should I just create a branch off of master?

Excellent, thank you! A pull request on master will be great. The branches need a little cleanup but we can sort it out.

Add a media item reference to AltTextController and set it before showing the vi…ew. Use that item's alt text to initialize the text view and make it first responder when the controller's view is shown. Update the media item's alt text when the user selects the "Add" button. Also remove unused outlets and commented out code. Tested by starting a new post, adding an image, and selecting the "Add Description" option for that image. Confirmed that the text is stored in the media item by entering some text, selecting "Add", and then re-selecting the "Add Description" option to see the same text. Confirmed that selecting "Cancel" leaves the text unchanged. Completed the post and confirmed that the text appears in the alt tag for the image.
