This is commit af7fba3263 along with all patches to it.
The experiment was largely a success so far. However, I saw a bug that was just strange enough to question whether this is too radical a hatchet.
As I recall, I grabbed a pane and then clicked on the surface. And I got this error:
Error edit.lua:219: bad argument #1 to 'ipairs' (table expected, got nil)
Traceback [love "callbacks.lua"]:228: in function 'handler' [C]: in function 'ipairs' edit.lua:219: in function 'mouse_pressed' run.lua:712: in function 'mouse_pressed_in_normal_mode' run.lua:677: in function 'mouse_pressed' main.lua:242: in function <main.lua:239> app.lua:31: in function <app.lua:22> [C]: in function 'xpcall'
Doesn't matter. I don't need a long tail of bugs in my software when nobody would notice just truncating the number of columns.
With this, pensieve no longer has an infinite surface. Back when I conceived of an infinite surface I didn't have search. But with (even just the current hokey iteration of) search it's easy to bring back a column. And the spatial metaphor seems pretty conclusively not working. I never have a sense of the big picture of the surface, and moving things in radical ways never feels choppy. That might be a good idea, but it's not for this product.
Thanks Jack Rusher for pushing back on the need for this idea. That got me to question it even though "everything seems to be working."
Let's see now if pensieve ever seems sluggish again.
