CloseUnsplitView
If you often do an unsplit after closing a message or error buffer you can combine these into one key command in your ~/.textadept/init.lua:
keys['ctrl+w'] = function()
if buffer._type then
buffer:close()
ui.goto_view(-1)
view:unsplit()
else
buffer:close()
end
end
NOTE: The above code is simple but doesn't work as intended when you have a
vertical split and you run the program/script in the left hand split. It's a
subtle point but ui.goto_view(-1) does not go back to the previously active
view, instead it goes to the view with view number one less than that of the
current view.
To get the desired behavior you need to goto the view above the current view
(the message buffer) before you do the unsplit, the only way I've found to do
this is to recursively search the split table, see ui.get_split_table().
Anyway here's the code that should work regardless of how the views are split.
function is_view(t)
return not (t[1] or t[2])
end
function get_view_num(v)
return _G._VIEWS[v]
end
-- Find upper view in horizontal split given view number
-- of the lower view
-- vnum is view number of lower view in horizontal split
-- t is the split table to search (recursively)
-- Returns view number of upper view or 0 if no such view
function split_walker(vnum, t)
local result = 0
if is_view(t) then
return 0
else
if ((not t.vertical) and is_view(t[2])
and get_view_num(t[2]) == vnum) then
return get_view_num(t[1])
else
result = split_walker(vnum, t[2])
if result == 0 then
result = split_walker(vnum, t[1])
end
end
end
return result
end
-- Goto view above the current view if there is one
function goto_view_above()
cur_view_num = _G._VIEWS[_G.view]
t = ui.get_split_table()
view_above = split_walker(cur_view_num , t)
if view_above > 0 then
ui.goto_view(_G._VIEWS[view_above])
end
end
keys['ctrl+w'] = function()
if buffer._type then
buffer:close()
goto_view_above()
view:unsplit()
else
buffer:close()
end
end
