JavaScript jamboree
It’s been a fun post-dConstruct week. Tantek has been staying in Brighton being, as always, the perfect guest. On his last night in the country, we went along to Async, the local JavaScript twice-monthly meet-up, host to a show’n’tell this time ‘round.
Tantek demoed his Cassis project. It’s nuts. He’s creating polyglot scripts that are simultaneously JavaScript and PHP, as well as having the ability to report which context they are running in. I feel partly responsible for this madness: he got the idea the last time he was in Brighton after reading Bulletproof Ajax and deciding that he didn’t want to write the same logic twice in two different programming languages. The really crazy thing is that he’s got it working.
Prem, who organised the event, showed his Sandie code: a security mechanism that allows external scripts to be loaded and arbitrary JavaScript to be executed without affecting the global scope. It’s smart stuff that could be incredibly useful for his sqwidget work.
Mark demoed one of the coolest bookmarklets I’ve seen in a while: Snoopy:
It’s intended for use on mobile browsers where you can’t view-source to poke around under the hood of sites to see how they’re built.
If the lack of “view source” on the iPad and iPhone has been bothering you, Snoopy is your friend.
Alas, we had to leave the Async awesomeness early to rendez-vous with the Mozilla HTML5 meet-up in The Eagle so I didn’t even get to see Jim demo the disco snake that he made at Music Hack Day last weekend.
