* experiment: slightly adaptive scrollingKartik K. Agaram2022-06-041-2/+14
| | | | | | | | | | | When long wrapping lines go past the current page, I find myself scrolling before I get to the bottom. So let's scroll less, usually from the start of the bottom-most line, even if it wraps multiple screen lines. The challenge with this is to ensure that a long line that fills the whole page by itself doesn't get you stuck. I take some care to make sure <pagedown> always makes forward progress.
* make cursor more obviousKartik K. Agaram2022-06-041-1/+1
| | | | | Let's see if this is good enough. I can also bump up to 4px radius if I need to.

* highlight selection while draggingKartik K. Agaram2022-06-031-12/+40
| | | | | | | Mouse stuff is pretty strenuous. For the first time I have to be careful not to recompute too often. And I ran into a race condition for the first time where resetting line.y within App.draw meant mouse clicks were extremely unlikely to see line.y set.
* select text using mouse dragKartik K. Agaram2022-06-031-2/+6
| | | | Doesn't yet highlight while dragging.

* more efficient undo/redoKartik K. Agaram2022-06-021-56/+36
| | | | | Now the bottleneck shifts to applying undo/redo in large files. But things should be snappy if you don't use the sluggish feature.
* renameKartik K. Agaram2022-06-021-12/+12
|
* this implementation undo load-tests quite poorlyKartik K. Agaram2022-06-021-0/+28
| | | | | | Even a 10KB file gets sluggish within the first 1k characters inserted. We're not running out of memory, we're just overloading Lua's GC.
* after much struggle, a brute-force undoKartik K. Agaram2022-06-021-0/+125
| | | | | | | | | Incredibly inefficient, but I don't yet know how to efficiently encode undo mutations that can span multiple lines. There seems to be one bug related to creating new drawings; they're not spawning events and undoing past drawing creation has some weird artifacts. Redo seems to consistently work, though.
* avoid scrolling down if possibleKartik K. Agaram2022-05-301-1/+28

* support non-text lines in Text.to2Kartik K. Agaram2022-05-301-1/+3
| | | | | Originally I was only using it on cursor line, but there's no reason that has to be true in general.

* selecting text and deleting selectionsKartik K. Agaram2022-05-291-4/+291
| | | | | | I've written a few tests for delete_selection, but the way different operations initialize the selection seems fairly standard and not worth testing so far.

* move some codeKartik K. Agaram2022-05-281-0/+28
| | | | | I had this idea originally to keep text.lua oblivious to drawings. But that hasn't been true for some time. Losing battle.

| | | | | I spent 20 minutes converting a manual test to a reproducible automated one, but in the process I knew exactly what the problem was. Nice.
