* support selections in the source editorKartik K. Agaram2022-09-061-1/+0
| | | | | I've only tested side A so far, and included a statement of how I want side B to behave.
* support drawings in the source editorKartik K. Agaram2022-09-051-17/+22

* editing source code from within the appKartik K. Agaram2022-09-031-5/+0
| | | | | integrated from pong.love via text.love: https://merveilles.town/@akkartik/108933336531898243
* set color for each fragmentKartik K. Agaram2022-08-231-1/+1
| | | | | In general it seems like good practice to minimize assumptions about the current color.
* helper: trimming whitespace from stringsKartik K. Agaram2022-08-231-0/+12
|
* fix a nameKartik K. Agaram2022-08-191-4/+4
|
* couple of accidental globalsKartik K. Agaram2022-08-181-2/+2
| | | | Luckily they didn't bite me yet.
* get rid of some ridiculous codeKartik K. Agaram2022-08-181-15/+5
| | | | | | I guess I wrote it before I settled into the idiom of: * first change cursor * then scroll if necessary

* remove some unnecessary workKartik K. Agaram2022-08-171-1/+3
|
* standardize scroll check in a few placesKartik K. Agaram2022-08-171-3/+3
| | | | | | | | | | | | I'm taking some lessons from pensieve.love here. It seem like specific pixel thresholds don't matter too much for plain lines.love. I'd probably feel safer if I just used Text.cursor_out_of_screen in these places, but it means we draw the screen twice for most events[1]. Let's see if we can get by with the current approach. [1] Or we have to start scheduling things for the next draw, which is more complex to orchestrate.
* simplify cursor-on-screen checkKartik K. Agaram2022-08-171-6/+6

* swap return valuesKartik K. Agaram2022-08-171-5/+5

* obsolete commentKartik K. Agaram2022-08-161-2/+0

* moveKartik K. Agaram2022-08-151-28/+28
|
* drop some unnecessary callsKartik K. Agaram2022-08-151-6/+0
|
* stop confusingly reading a globalKartik K. Agaram2022-08-151-2/+2
| | | | | | | The way Text.draw is called by edit.draw, we know it'll never be called for lines above screen_top1.line. Comparing every line on screen with screen_top1 makes no sense. The intent is really just to compare with screen_top1 only for the first line, and otherwise to ignore this check.
* bugfix: handle drawings when updating screen topKartik K. Agaram2022-08-111-0/+1
|
* renameKartik K. Agaram2022-08-111-24/+24
|
* bugfix: pagedown was sometimes bouncing upKartik K. Agaram2022-08-101-1/+1
|
* bugfix: backspace from start of final lineKartik K. Agaram2022-08-101-1/+5
|
* unnecessary argsKartik K. Agaram2022-08-101-1/+1
|
* click to the left of a lineKartik K. Agaram2022-07-291-2/+1
|
* bugfix: searchKartik K. Agaram2022-07-211-1/+1
| | | | | Broken since commit 188bbc73 9 days ago :/ At least we have a test for it now.
* use line cache for drawings as wellKartik K. Agaram2022-07-201-26/+26
|
* bugfix: where cursor is drawnKartik K. Agaram2022-07-201-4/+11
| | | | | | | The published version of lines.love was broken for almost an hour. The cursor would render one position to the right of where it really is. To fix it, this commit rolls back 26ba6e4e5a71. There doesn't seem a good way to test it.
* .Kartik K. Agaram2022-07-201-0/+2
|
* exclude left margin from my word-split heuristicKartik K. Agaram2022-07-201-1/+1
| | | | | Gratifying how few tests need changing. Recent commits seem on the right track.
* allow Text.nearest_pos_less_than to return 0Kartik K. Agaram2022-07-201-5/+2
| | | | This eliminates another case of overflowing margins.
* drop an unnecessary level of indentKartik K. Agaram2022-07-201-23/+21
|
* clean up some printsKartik K. Agaram2022-07-201-17/+10
| | | | | (Looking at prints in Text.draw, Text.compute_fragments and Text.nearest_pos_less_than)
* move a var closer to its useKartik K. Agaram2022-07-201-2/+2
|
* more clearly skip prints before screen topKartik K. Agaram2022-07-201-21/+19
|
* 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
|
* separate data structure for each line's cache dataKartik K. Agaram2022-07-171-50/+58
| | | | I have no idea what the performance implications of this are..
* keep all text cache writes inside text.luaKartik K. Agaram2022-07-171-5/+5

* switch to line index in a functionKartik K. Agaram2022-07-171-2/+3

| | | | - Text.compute_fragments
* make a function oblivious to line data structureKartik K. Agaram2022-07-171-5/+5
