Hello, the desire to be able to write activities using html has been expressed several times by developers. We have seen several approaches but there is not much support for it in the core platform yet. I and Simon have been trying to figure out how to best integrate this with the existing platform. Bits of code can be pulled from the sugar-build html branch. We don't have much of a demo yet, but I think the basic pieces of the infrastucture are becoming clear, so I thought it would be good to try and summarize them in an email to the list. 1 sugar-toolkit-html * A new module. * Independent from the native sugar API, so that html activities might be run on other platforms, like Android or even inside a web browser. * HTML equivalents of the gtk widgets. For example Toolbar and Palette. * Per-platform (sugar-os, android, web-browser...) implementations of the same javascript interface to the sugar services. For example it might provide a datastore.save(metadata, file) method or an icon.get_with_colors(xo_colors) 2 sugar-http-server * A sugar-os internal component. Other platforms might implement the html/javascript API without even using an http server. * Implemented by the sugar-toolkit-html module but managed by the sugar shell. * Serves the activity bundles content with something like http://localhost:8000/org.sugarlabs.HTMLDemo/index.html. * Exposes the sugar services API with json methods like http://localhost:8000/org.sugarlabs.HTMLDemo/datastore/save
As we talked about today, I was looking at node-dbus [1] in order to talk to the DS over dbus from java script. Looks straight forward. I installed the module (npm install node-dbus) and did a quick example based on the test in the repo to listen on the 'Created' signal from the DS. Works fine.
Of course, if we use nodejs we have to handle the modules packaging as nodejs itself is rather limited and a most of the functionality is in the modules.
Cheers, Simon [1] https://npmjs.org/package/node-dbus
