Split window

Hey VisiDaters, check it out!

In the bleeding-edge develop branch, VisiData can now show TWO sheets at the same time:

The ability to see two sheets on the screen at the same time has been on the v2.0 roadmap for a long time. I've even caught myself lamenting a few times that, if we had split-screen, the design for some feature would be straightforward. Deep down I also think it might open up a whole new dimension of user interface, where movement on the active window instantly updates the inactive window.

So I've given it a few tries already; it's not that technically challenging to do, but the interface for it remained elusive After talking with @tsibley and @anjakefala and sitting with it for long enough, last week I finally put together a working prototype. It's serviceable but not perfect, so hopefully it can serve as a launching pad for discussion about the finer points of split-screen workflow.


The main option is disp_splitwin_pct, which specifies the height of the top window as a percent of the full screen height. Currently, a positive number puts the top sheet in the top window, whereas a negative number keeps the same layout, but puts the top sheet in the bottom window.


Its full implementation could solve several issues (choosing jointype/aggregators, popup command help) and would make a two panel orthodox file manager all but inevitable.

This is still quite experimental so if you use this feature, let me know how you feel about it! Post an issue on Github, share a tweet , or stop by for a chat in freenode #visidata.
