Remove webassets from sagenb?

[Volker Braun]

Webassets doesn't install with the new docutils (http://trac.sagemath.org/ticket/16736). What is it used for, and can we just remove it?

Good question, though presumably for something!   In #13121, we have

"new dependency on webassets for js/css autominification (not currently used in the master branch)"

Especially things like

sagenb/data/webassets_generated/jmol_popup.js

in your list seem to indicate that there are a few places we might minify js using this in sagenb, though I was not able to verify whether these were the specific js files used in actual running sagenb.  And you'll note that https://github.com/sagemath/sagenb/tree/master/sagenb/data doesn't have a webassets_generated folder, but I don't know if that means these are just unneeded sources or whether we really don't use it at all... unfortunately a lot of the people who might know this are not currently active.  This dependency was apparently added in https://github.com/sagemath/sagenb/commit/38327cae5a9e33f5ab1c90c0c27075df6d697f75 ... 

Got it.  This is only there so that people can use the "newui" branch (which apparently is quite nice but under tested).  See https://github.com/sagemath/sagenb/commit/6a8330ae7e907ac9c73b28a410286dd9384dd2dd

 Add @samuela's branch's dependency to spkg-dist

This way the spkg will still only contain sagemath's master, but you can

fetch and play with @samuela's branch without having to rerun `setup.py

develop`.

That took more time to track down than I would have liked.   So I guess we can indeed scrap it, though if we can keep samuela's branch compatibility (this is called the "newui" branch on github) that would be good for honoring that contribution, as someone may have time to do this in the long run (sagenb may not be cutting-edge but it is still the best choice for a lot of local work; I assume it is lighter-weight than whatever local SMC comes up but assumptions are dangerous).  Anyway, hope this detective work was useful.

By the way, webassets seems to be at 0.11 and perhaps upgrading it would do the trick as well.

I tried that already

Actually if you are using KDE there is an interesting alternative to sagenb:
"cantor" http://www.kde.org/applications/education/cantor
Pity it doesn't work on OS X.

Yes, I've heard about this, though I haven't used it.  Pity lots of things in the open-source world don't work other than on certain Linux setups... such as Sage on Windows ;-)

Okay.  Hmm, I guess it would be pretty easy to remove it by just removing those dependencies in two places.  If fbissey's option of patching webassets is easier we can do that too. 

[P Purkayastha]

Is any Sage developer working on Cantor? I used it a couple of years ago, and found it lacking (will have to look at it again to recall the issues I had with it). It seemed like it had a lot of potential though.

[Ivan Andrus]

Has anyone tried? You can install KDE libraries with homebrew (or fink, or mac ports). It’s not inconceivable that cantor could work.
