* move some codeKartik K. Agaram2022-05-282-28/+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 saw screen_top not at start of screen line, but at cursor location in middle of line.

| | | | | 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.

| | | | | | | | | | | | | | | | | | | | I'm now extracting the concern of computing line.screen_line_starting_pos out of Text.draw. Earlier I had to make sure I ran through the whole line to compute screen_line_starting_pos, but that had the side-effect of updating Screen_bottom1.pos as well with lines that had never been rendered. In this process I hit my first bug due to an accidental global. It doesn't show up in the patch because I accidentally deleted a local declaration. (I thought I didn't need screen_line_starting_pos anymore, deleted everywhere, then brought it back everywhere from the bottom of the function up, but forgot to put back the very first occurrence.) The amount of yoyoing this caused between App.draw and Text.draw, I very much have spaghetti on my hands. Accidental globals are _terrible_ in a program with tests. Cross test contamination X-(

* first successful pagedown test, first bug found by testKartik K. Agaram2022-05-234-14/+86
| | | | | | | | | | | | | | | | | | | I also really need to rethink how people debug my programs. My approach of inserting and deleting print() takes a lot of commitment. I need my old trace-based whitebox testing idea. However, in my past projects I never did figure out a good framework for tweaking how verbose a trace to emit. Perhaps that's too many knobs. Perhaps we just need a way to run a single test with the most verbose trace possible. Then it's just a matter of having the trace tell a coherent story? But even if the trace stays out of program output in that situation, it's still in the programmer's face in the _code_. Ugh. Current plan: ship program with maximum tests and zero commented-out prints. If you want to debug, insert prints. This is better than previous, text-mode, projects just by virtue of the stdout channel being dedicated to debug stuff.

| | | | | | | | | | | | | | | | | | | I have no fucking idea what I'm doing. All I know is that there's still too many goddamn bugs[1]. Test motherfucking harness or bust. For starters this is just the default love.run from https://love2d.org/wiki/love.run [1] The following file crashes if you repeatedly press cursor-down: << a b c ```lines ``` x >>
