By default Textadept's strips off trailing whitespace from all lines. This is a good thing, especially if you are using version control. To avoid moving the caret when you have just carefully found your position in some deeply nested code, this extension saves your position and by enabling virtual space keeps the cursor's position. If another key is pressed the necessary spaces are inserted again. To see what is going on enable view whitespace. |

Variable to save the current column. |
local saved_col
|
|
Save position before saving. |
events.connect('file_before_save',
function()
local buffer = buffer
saved_col = buffer.column[buffer.current_pos]
end, 1)

Go in virtual space to position the cursor was at before saving. |
events.connect('file_after_save',
function()
local buffer = buffer
if saved_col > 0 then
virtual_space = buffer.virtual_space_options
buffer.virtual_space_options = 2
local col = buffer.column[buffer.current_pos]
local diff = saved_col - col
if diff > 0 then
for i=1, diff do
buffer:char_right()
end
end
buffer.virtual_space_options = virtual_space
end
end)
