Re: Completion Framework for TeXmacs

Dear Owen, 

I'm not familiar with Ivy/Helm. Can you briefly describe what you would like to obtain? On one side TeXmacs provides already scheme sessions embedded in a document. So you could simply either have a document with code which can be sequentially (re)evaluated (a la jupyter notebook or mathematica files). If you want to have, on one side a scheme file and on another a buffer where to evalute, I would try to create a new document with a session and then come glue code in scheme which allows to select part of a scheme file and send them to the other document for evaluation. This should not be too difficult. 

Note that with scheme you can also programmatically create dialogs (but not full fledged editor windows yet). However there are a couple of widgets you could be interested in : one is texmacs-input and the other texmacs-output. The second allows to render arbitrary documents, while the first is a full editor, but you do not get the toolbars nor the menus...
You can see some examples in TeXmacs/progs/kernel/gui/menu-test.scm


for example, open a scheme session and then do

(show (widget6))

to see the two widgets I mentioned above in action.


Best
Max
