Themes for notebook

[migeruhito]

You can now add full new themes to Sage. From light css touches to full template system replacement. I have used flask_themes2.

I have tried to keep changes in the sources at minimum, but jinja2 initialization process had to be modified and, as consequence, the rendering of worksheet templates.

Several test themes are included in this branch. There are two locations where themes can be placed. One place is a special new directory sagenb/sagenb/themes, intended for providing official distribution themes and/or system wide available themes. The other place is a directory themes in SAGENB_DOT. Some documentation was added in the help menu. For more information about how to write themes, see flask_themes2 docs.
Warning flask_themes is broken and is incompatible with newer versions of flask.

You must make flask_themes2 available in the local sage's python path in order to test this feature. An appropriate dependency was added in setup.py.

I know that a new UI redesign is coming. Could this extension make this transition smoother?

I like that you were somehow able to get the "new UI" in here as a theme that could be selected between. I certainly don't have time to pore through all these massive changes now :) but please do update with comments here what your status is! Making it easier to work with this as you have done is a really valuable contribution.

I'll work to incorporate newUI as a theme. A year ago, I incorporated Samuel Ainswoth's pull request for newUI as a fully functional theme in a way compatible with classic themes. The changes were not massive, but subtle. Today, this theme doesn't work any more. I use classic themes with this branch in my classroom sage server, available at https://farto.eis.uva.es:8080

Today, this theme doesn't work any more.

Oh, I didn't realize that. What changed in the meantime? There haven't been very large changes here, as you are no doubt aware...

Anyway, the current pull request you have here includes that newUI, as far as I can tell.

I mean the newUI theme of my themes branch doesn't work any more. Sorry.

I have been disconnected from here for a year. The themes included in my themes branch are mere examples to test the concept. I use one of them in production, but it is anecdotic. I'd like to get the "new UI" in here to work as a theme and substitute the current newUI theme by it.

sagenb/newui branch has been converted in the theme newUI. Intensive testing is needed.

Now a change from a classic theme to a newui theme can be done without restarting the notebook.

sagenb is now in maintenance only mode
