Might be better to do it based on the page types included, could probably be done by regexp.. for example you might want to provide a download link (within a text field) to an .mp4. Otherwise you'd have to parse the xml which would increase the time further.

This is part of my point about sticking to only xml. If save.php could write a compatible json object then we could skip a lot of the parsing. We could even parse it at save time and include a option then?

no, this is loading scripts you need for your piece (because you have added them to the list, you must need them)

You’re thinking of the Maths and Mediaelement stuff I think, which, yes, loads every time.

It’s probably not so hard to search for mp4 flv `` in the file and load those libraries as appropriate.

Ok, but that's loading the scripts even if not needed? So not on actually demand but possible demand?

I think that’s why I added that lsit to the LO root icon, so they could be loaded before parsing the content. Maybe we should add that to the other template as well?

I’ve added a list on the LO icon where you can add the libraries you want, also a stylesheet, so then you can easily define  <div id=”chart” class=”ChartClass”/> in the piece by hand, and use script to set it up:

That would be fine – I thought this was more for end users

Have a dropdown with the libraries prepopulated and for each supported one, an array or sources for fallback. If you get a 200 you move on, if you get something else you try the next in the array…

You can also do it this way and execute the callback when the script has loaded to use it.

D3 is probably the ultimate in charting tools and is HUGE i agree but a lot of that is the data manipulation routines, cross browser, legacy browser support stuff... Don't we potentially want all them too?



Making it a jquery plugin doesn't actually have that much overhead but i think they could/should further split the sections into sub plugins so that you can pick and choose which you require...



Its only 135kb minified though - not much or any bigger than 1 decent sized image - what we need to do in xenith is enable on-demand loading/background pre-fetching of these libraries i think and then there isn't an issue...



See here though for others http://techslides.com/50-javascript-charting-and-graphics-libraries/



I was actually wondering whether we should just make the editor code into jquery plugins which leverage the power of jquery chaining and oop in a sense, so something like:



$('#treemenu :nth-child(6)').insertBranch('...').bind('click', function().... Etc



Easy to do, maintain and read...

It is a plugin, but you could link the raw GitHub stuff to save space.



I think the jquery in XOT could be moved into a library into which D3 could be added



I've got two D3 plugins half developed, but I've just bundled the JS in

There are some really nice examples on their site. I think it’s abit more than I need: it seems to be a whole jquery like plugin, rather than just the charting stuff.



This is one example where being to load libraries from a CDN would be good, because then people can choose. I don’t know if you can make the charting setup FWS for anything but the simplest charts, which we already have.



After equations though, academics would make a lot of use of charts. I suppose they can do them as images, but it’s a bit of a hassle.

The ability to show a range of charts would be a good addition to the site template, and the toolkit, it would complement the MathJax stuff nicely.



Does anyone have any recommendations?
