Link Unfurling For WebTalk

This library and associated modification to the webtalk front-end will unfurl incoming links, giving you previews of links and expanding images and youtube videos.

A simple %gall app watches your porch (your incoming %talk messages) and, when it sees a candidate for unfurling, it checks the url to see if there is available metadata, or otherwise expands the link. The resulting metadata is then inserted into your porch (invisible to the rest of the %talk channel), where it is formatted by a modified version of webtalk.

Setup

1. Install %gall application

• This application depends on ~palfun's string library https://github.com/Fang-/urbit-string
• Copy the contents of the /app and /lib directory from this repo into the appropriate locations on your planet. Better distro methods forthcoming!
• In %dojo run the following commands:
• |start %unfurl
• :unfurl %listen
• To stop the app from unfurling links, you can run
• :unfurl %ignore

2. Install front-end

• If you'd like to keep your original webtalk pristine, copy the contents of /home/web/talk to somewhere civilized
• Copy the contents of this repo's /web/talk into your ship's /home/web/talk
• If you'd like to poke around at some very poorly written coffeescript, check here http://www.github.com/vvisigoth/talk/tree/unfurl
