TJoseph, it looks like an interesting way of doing things
-- I have considered node.js as a vehicle ontop of HAL for a while, and looked into things like extending it for HAL access, despite some duplication for instance with mongoose which emcweb is based upon my take is: node.js functionality and speed are appealing. But it is extremely in flux, it is _huge_, and hence I have reservations importing node.js into LinuxCNC as a requirement. That doesnt mean it shouldnt or cannot be used, but I dont think it should be a cornerstone things should rest on in LinuxCNC. The functionality required to talk to HAL over Websockets/JSON is rather minimal and can be provided by a fairly simple server based on libwebsockets, and the jansson library, giving HAL web networked I/O functionality. The whole thing is on the order of say a thousand lines of C, which is perfectly understood and can be fixed/extended within this community. This would run on a given URI; whatever people choose to serve to the webclient on another URI is their decision. What we need to come up with is a standardized JSON/ws interaction flow any JS application can talk to that HAL ws/json server. Wherever widgets and other stuff comes is orthogonal to that. I would think the widgets in bitlash would be worth investigating. - Michael Am 08.06.2013 um 17:17 schrieb TJoseph Powderly <tjt...@gmail.com>: > this thread has grown a bit > > for the part of the thread concerned with web gui interfaces... > 'bitlash commander' is interesting > > https://raw.github.com/billroy/bitlash-commander/master/public/images/screenshot-servolab.png > > using this web interface, > i have an exer-bike hooked to an arduino, to a meter, to a threshold, to > an ssr, that should ( not yet ) turn off the damn laptop unless i pedal > harder ( oughtta be a hal -gui sez i ) > > for the part concerned with hal web visualization ( i read hal di-graphs > made useful in a browser ), > this is interesting ( the standard 'dot' record idea, using svg and in a > browser window ) > take kent's advise , use Ctrl+ Ctrl- Ctrl0 and the cursor keys to zoom, > pan, and restore ( sigh the Ctrl mouse keys died with Adobe's SVG plugin ) > lookee here, imagine the records are hal widgets > > http://my-wordpress.ru/lesson/visual-db/ > > regards > tomp > > ------------------------------------------------------------------------------ > How ServiceNow helps IT people transform IT departments: > 1.
