2 years ago Option introspection would be nice to have in general. I would like to see the ability to run :set ignorecase and have the current value printed as an info message. We already have toggle capability via ! for non-visual boolean options like that, but e.g. for ignorecase, without testing a search pattern it is not easy to know what the result of :set ignorecase! is.
There's a possible issue with a unified api, in that some options are tied to specific windows and other acting globally.
This should be fine, window-specific options can be at vis.win.option where global options can be vis.option, etc. Looks like that's already the case, with some other namespaces like file and ui as well:

I guess we just need to decide where the remaining options should go. Could require some refactoring and new drawing logic if we want to make more things window-local (which can quickly get overcomplicated):
search_direction-> global optiontabwidth-> in vim,tabstopet al. are buffer-local, but that seems weird. Window-local makes more sense to me, but even that might be overkill.expandtab-> same astabwidth.autoindent-> same astabwidth.change_colors->vis.ui.change_colorsignorecase-> global optionshell-> global option, read-only
That's the most obvious stuff I could see in https://github.com/martanne/vis/blob/master/vis-core.h, although some of the other things may be interesting to expose for some advanced plugins, I suppose.
Plugins should be able to read the values of options from lua somehow. Currently options can be set with
vis:command, but they cannot be read. I specifically want to be able to readexpandtabandtabwidth, but I think a more generic mechanism is needed. It's worth noting that vis already exposes thesyntaxoption withvis.syntaxandvis:set_syntax.There's a possible issue with a unified api, in that some options are tied to specific windows and other acting globally.
