I'm pleased to hear we're back to Leo being an alternative to, rather than a copy of, Emacs :-) > @button, Leo's API and Leo's DOM, combined with python scripting, are much more convenient and powerful than org-mode. Simplicity and generality are more important than a org-mode features. Leo most definitely has the chops to support reproducible research, or any other buzzword one wants to use.> > Leo 5.5 will have an execute-script-in-common-namespace command. This can be added with only a few lines of code. It's needed to simulate pyzo/jupyter/org mode calculations. vs-eval / vs-last / vs-pretty do this. I added them to the inscrutable valuespace plugin because it already creates a common namespace (c.vs), but really they should be separate, seeing they're straight forward and easy to understand, unlike the rest of valuespace ;-) > Leo 5.5 will also have a show-drawer command.
