961ce63023 begin refactoring to let cursor move to very last char of file (including unix line ending) 2025-09-23 10:50:10 +01:00
21e12addf3 in text builders, check when on newline if this is the second last character in the file, and draw it on a newline if so. This is to align with the design decision that we want the second-last character to be selectable 2025-09-23 09:16:02 +01:00
d63201ada7 reimplement vi's 'l' motion so that we only skip a newline when it is preceded by a non-newline character 2025-09-21 17:49:30 +01:00
97936b83a0 in TextBuilder functions, when we encounter a newline, we want any cursor here to be drawn after a linebreak (after the posX and posY values go to the next line) and not before 2025-09-16 22:29:19 +01:00
ae1772605b in TextBuilderWithHighlight.build, check when we encounter a \n if we would be past the last line, and return the acc if so, or else continue looping 2025-09-14 10:39:51 +01:00
4bc6c54951 in TextBuilder.build functions, when we encounter a space, check if we are before the scroll column's start, and set the x position to startX if so. This is done in preparation for the character which is actually at the scroll column's start, which will be added at the wrong offset unless we do this. 2025-09-14 08:42:46 +01:00
2ab48626cd remove 'skipToFirstVisibleColumn' function in TextBuilder, as control flow is simpler if we have fewer mutually recursive functions and we can implement its functionality in the 'build' function instead. Also change the 'z' values for cursor and highlight; the cursor should appear above the highlight and now it does, but it previously didn't 2025-09-13 23:22:40 +01:00
a3b00e09d8 port over bug fixes from mutually recursive functions from test-builder-with-cursor.sml to text-builder-with-highlight.sml 2025-09-13 03:02:13 +01:00
20a542df29 in BinSearch.equalOrMore and BinSearch.equalOrLess, return ~1 if no item is found, for the sake of less ambiguity in usage. Functions that call these have also been adapted. 2025-09-13 02:18:14 +01:00
422d6ad9ac fix bugs in implementing and using text buffer. Some functions did not save the drawMsg to the app's state, which we means we didn't draw in those cases. The text builder functions also drew cursors on characters even when the cursor is not at this position. Both of these bugs are fixed. 2025-09-12 23:21:53 +01:00
77a64ae794 previously forgot to draw char in text builder, but we do that now 2025-09-12 14:02:38 +01:00
67db4804fb implement function to initialise env for text builder 2025-09-12 11:17:11 +01:00
