This is still very alpha experiment

Skyedit is an editor embedded in browser. Some browsers support view-source:* type URIs for viewing page source (Try clicking view-source:http://google.com in Firefox or Chrome). In a same way you could view source for a files in the local hard drive view-source:file:///etc/hosts. Would not be it nice to have similar way to edit those files ? Would not be it awesome to have an edit link edit:https://gist.github.com/raw/648918/2520e8264bd20d9b1d58848e369ab15c9f665bd6/read-lines.js on a gist page along with embed to start editing it an editor, or just being able to navigate to edit:file:///etc/hosts to edit it ? This is an experiment using jetpack and ace with an attempt to do exactly that and probably more in a future.

git clone git://github.com/Gozala/sky-edit.git --recursive
cd sky-edit

Download latest .xpi file from downloads and drag it to firefox.
