Ultimately boils down to getting `height` and `width` for:
- prompt
- preview
- results
No matter what you do, I will not make prompt have more than one line (atm)
Result of `resolve` should be a table with:
{
preview = {
get_width = function(self, max_columns, max_lines) end
get_height = function(self, max_columns, max_lines) end
},
result = {
get_width = function(self, max_columns, max_lines) end
get_height = function(self, max_columns, max_lines) end
},
prompt = {
get_width = function(self, max_columns, max_lines) end
get_height = function(self, max_columns, max_lines) end
},
total ?
}
!!NOT IMPLEMENTED YET!!
height =
1. pass between 0 & 1
This means total height as a percentage
2. pass a number > 1
This means total height as a fixed number
3. {
previewer = x,
results = x,
prompt = x,
}, this means I do my best guess I can for these, given your options
4. function(max_rows)
-> returns one of the above options
return max.min(110, max_rows * .5)
if columns > 120 then
return 110
else
return 0.6
end
width =
exactly the same, but switch to width
{
height = 0.5,
width = {
previewer = 0.25,
results = 30,
}
}

After we get layout, we should try and make top-down sorting work.
That's the next step to scrolling.
{
vertical = {
},
horizontal = {
},
height = ...
width = ...
}

--- Win option always returns a table with preview, results, and prompt.
