How to draw lines using tilemap with gdscript. In the editor we can use Shift+LBM. Alternatively, could I download the godot source code and sprite it into godot.

I know that godot is subtitled in c++ and I am not concerned with copy paste options just an idea.

I would like there to be the same drawing preview as in the editor and when we release the mouse the tiles just appear.

Since there is no antialiasing involved you can use simple naive line drawing algorithm In pseudocode:

# (x1, y1) and (x2, y2) are endpoints
# x1 must be smaller than x2

var dx = x2 − x1
var dy = y2 − y1

for x in range(x1, x2+1):
    y = y1 + dy * (x − x1) / dx
    set_tile(x, y)
