* unify two similar functionsKartik K. Agaram2022-07-191-11/+4
| | | | | | The cost is just having to tweak a few more brittle tests. I can't actually perceive any difference in how the cursor moves when I click on text.
* keep text from overflowing right marginKartik K. Agaram2022-07-191-5/+15
| | | | | | | | | | I've been sloppy about this so far, and outside of tests I can't find any examples where it matters, but it matters in a potential fork where I'm rendering multiple columns of text. It's unfortunate that my tests have this level of brittleness. What I'd really like to assert in many of these changed lines is that the text stays inside the margins and that more text would overflow margins.
* bugfix: couple of margin-relative computationsKartik K. Agaram2022-07-171-2/+2
|

|
* bring back a set of constantsKartik K. Agaram2022-07-161-3/+3
| | | | | It's starting to sink in that I don't want hard-coded constants inside objects.
* replace globals with args in a few functionsKartik K. Agaram2022-07-121-3/+3
| | | | | | | | | - Drawing.draw_shape - Drawing.draw_pending_shape - Drawing.in_drawing - Drawing.find_or_insert_point - Drawing.near - Drawing.pixels

| | | | | Editor state initialization now depends on window dimensions, so we have to more carefully orchestrate startup.
* add state arg to a few functionsKartik K. Agaram2022-07-121-107/+93
| | | | | | | | | | | | | - Text.cursor_at_final_screen_line - Text.move_cursor_down_to_next_text_line_while_scrolling_again_if_necessary - Text.snap_cursor_to_bottom_of_screen - Text.in_line - Text.to_pos_on_line - Text.to2 - Text.to1 - Text.previous_screen_line - Text.tweak_screen_top_and_cursor - Text.redraw_all

|
* stop pretending globals are localKartik K. Agaram2022-07-111-4/+0

* start passing left/right margins everywhereKartik K. Agaram2022-07-081-8/+8
| | | | | | | | | | | I have a set of changes that passes all tests, but I'm going to commit them very carefully to ensure I don't miss any call-sites. In this commit I'm adding the args to: - Text.draw - Text.tweak_screen_top_and_cursor But calls within them don't yet pass them where they should. In this manner I'm going to progress systematically from the top down.
* rename a couple of variablesKartik K. Agaram2022-07-081-10/+10

* drop an arg from a functionKartik K. Agaram2022-07-081-1/+1
