c29afbdb7c fix minor bug regarding 'NormalMove.moveCursorDown': after a <count-j> that moved the cursor to the last line in the buffer, the cursor would be at the last column too, even if that wasn't the previous column. To address this issue, we take out code that calculates the lineIdx from the 'NormalMove.finishMoveCursorUpDown' function, and have both 'NormalMove.moveCursorUp' and 'NormalMove.moveCursorDown' calculate their own lineIdx in different ways and pass it to the 'NormalMove.finishMoveCursorUpAndDown' function. 2025-09-20 02:58:51 +01:00
090e7ccea2 pass 'maxLength' value to TextScroll function so that we can prevent scrolling past the bottom of the file (unless we want to od so by centtering the screen) 2025-09-19 23:17:28 +01:00
d3fa4d08bf extract reusable function containing common code previously used in both 'NormalMove.moveCursorUp' and 'NormalMove.moveCursorDown' functions, and make them call the reusable function instead 2025-09-19 22:40:29 +01:00
859860b19f reimplement vi's 'j' motion, and remove the original function for this motion which was in cursor.sml 2025-09-19 22:33:37 +01:00
2c88341c37 remove code which became dead after reimplementing vi's 'k' motion 2025-09-19 05:27:10 +01:00
9ec8891ce5 fix bugs in new function for moving cursor upwards, taking care to calculate column different if on first line (where there is no preceding newline) vs any line other than the first 2025-09-19 05:23:20 +01:00
4c1a76ae67 begin reimplementing motion to move cursor up (vi's 'k' command), although it is in progress and buggy 2025-09-19 04:59:40 +01:00
e4e3961d41 in NormalMove.moveToLine function, use new LineGap function, 'LineGap.lineNumberToIdx', to get the index a line is at, and delete the Cursor.getLineStartIdx' function which we no longer need, as that functionality is in brolib-sml itself. 2025-09-19 04:45:29 +01:00
38c1766b14 pull in new version of brolib-sml, which adds a function to convert a line number to an index 2025-09-19 04:38:52 +01:00
b6244d4962 amend motion to move to a line: if the requested line has a linebreak as the next character after it, stay at the current position, or else add 1 to the linebreak's idx so that we go to the first character of the line 2025-09-19 04:03:54 +01:00
d871ac451f restore temp.txt to previous state, as it was temporarily being edited for testing 2025-09-19 03:04:10 +01:00
ab2f2cc752 simplify 'vi-hl-dfa's DFA, removing one state 2025-09-19 02:40:14 +01:00
ad7d103f61 rename 'ViLDfa' structure to 'ViHlDfa' since this DFA implements both vi's 'h' motion and vi's 'l' motion 2025-09-17 11:02:11 +01:00
dbf05ec8dc refactor Cursor.viH to use DFA 2025-09-17 10:45:37 +01:00
9ddb5f68d7 fix bugs in vi-l-dfa (we want to stop looping when the counter is ~1, because the starting character will likely be final/a not-newline, and we want to loop at least once; also, we want to special case 'twoNewlineState' as a final case which causes us to go backwards by 1 instead of treating 'oneNewlineState' as a final/special case). We also modify other code to use the new vi-l implementation in the program. 2025-09-17 03:52:31 +01:00
5174a5b0a4 adjustments to vi-l-dfa: we should accept a single-newline as a final state, but not a double-newline 2025-09-17 02:35:32 +01:00
161caee62a create DFA for Vi's 'l' motion 2025-09-17 02:31:38 +01:00
c94aa72015 create 'MakeIfCharFolderNext' functor, which mirrors the 'MakeIfCharFolderPrev' functor that we already have 2025-09-17 02:20:36 +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
1adb74df2c pull in new brolib-sml changes (which just changes one particular function's name to be clearer), and modify code to use the correct name 2025-09-16 22:20:55 +01:00
c4fedc6434 fix 'Cursor.getLineStartIdx' function, which should look at the left nodes if there is no relevant line in this node 2025-09-16 22:09:15 +01:00
96521f358f when looping through a DFA in a functor, make sure we return the absolute index to the calling function and not a modified version of the absolute index which has already been clipped 2025-09-16 21:35:48 +01:00
12478f8ac2 remove references to 'Cursor.clipIdx' and delete that function once it is no longer used 2025-09-16 16:08:01 +01:00
578d3af5ec remove changes to temp.txt which were only for testing 2025-09-16 15:55:16 +01:00
19d2235686 refactor 'MakeNormalDelete.removeLineBreaks' function to remove function call to 'Cursor.clipIdx', instead relying on textLength field in buffer 2025-09-16 15:53:41 +01:00
2c5449dc0a rewrite 'MakeMove' functor in fcore/move.sml to use textLength field instead of Cursor.clipIdx function 2025-09-16 07:59:26 +01:00
148b108062 when using 'G' command to move to end fo file, use the 'textLength' field to calculate the new bufferIdx, which is more sensible than using the LineGap's idx for the same purpose 2025-09-16 07:52:47 +01:00
3d9bf962e7 handle additional deleteLine edge case 2025-09-16 07:40:58 +01:00
70ffea21b3 fix the last MakeNormalDelete.deleteLine bug: if we delete such that the startIdx (prior to deletion) becomes longer than the text in the buffer, we move the cursor to the start of the last line 2025-09-16 07:01:55 +01:00
6507b9d49c adjust MakeNormalDelete.deleteLine implementation slightly, because the previous implementation did not delete the last character when we are at the end of the file 2025-09-16 06:29:35 +01:00
169f96f459 fix exception when the buffer is empty 2025-09-16 04:35:49 +01:00
0793744e24 minor bug fix: when we start looping backwards in a DFA and the rightStrings is empty, start iterating from leftStrings if possible 2025-09-16 03:05:33 +01:00
820a6c2462 copy new file order from shf.mlb to shf-tests.mlb, and remove split-string tests because we have tried to refactor string-search logic to be separate from the data structure 2025-09-16 01:25:27 +01:00
873fa1b1ac pull in update to brolib-sml, which gives us a LineGap that has textLength and lineLength fields 2025-09-14 15:54:59 +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
9b34014af1 a few bug fixes to NORMAL_SEARCH_MODE: the main one is that we were passing the general searchString to the resize function before, and we were drawing the wrong string because of that; another bug fix is that, on resizing, we have to update the mode to contain the recalculated searchScrollColumn 2025-09-14 10:28:42 +01:00
0632f7a969 add horizontal scrolling functionality to SearchBar 2025-09-14 10:07:43 +01:00
f1a06f946d add searchScrollColumn to NORMAL_SEARCH_MODE variant, and update and recalculate it where needed 2025-09-14 09:50:07 +01:00
b556fc7d63 extract a reusable function to calculate the scroll column in different contexts (can be used for a plain string or a LineGap.t; doesn't matter) 2025-09-14 09:22:37 +01:00
428208f9bf when text is wide enough to be centered, also centre the search bar 2025-09-14 09:14:22 +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
120568a18d modify 'TextBuilder.initEnv' function to take 'startX' and 'startY' parameters, instead of hardcoding the startX/Y inside the function, and change width/height calculations to take these parameters into account 2025-09-14 08:24:37 +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
7a388f2983 add TextScroll function for centering line to cursor, and use it in 'NormalFinish.centreToCursor' function 2025-09-13 18:23:55 +01:00
18d2579605 remove todo-exception from 'G' (NormalMove.goToEnd) command. The todo was a reminder to implement a way to get the scroll line when moving to the end. We have that implemented now. 2025-09-13 18:15:30 +01:00
bfb653e059 pull in new changes to brolib-sml, which fixes the LineGap.goToLine function to properly go to the start of the line 2025-09-13 18:04:23 +01:00
bbe39f90d4 move cursor to low/cursorIdx in helper function 2025-09-13 08:48:00 +01:00
9208c47622 fix exception caused by resizing in normal mode: we were passing 'buffer' to the TextScroll function previously, but we were meant to be passing 'newBuffer'. We are passing 'newBuffer' in this new commit as we are meant to. 2025-09-13 05:31:11 +01:00
2a332f543a minor adjustment to vertical TextScroll: we shouldn't need to move the cursor to the very line in the visible area, or the ver first line in the visible area, to scroll. We scroll if the cursorLine is some distance close to either edge instead. 2025-09-13 05:24:51 +01:00
668dd07699 pull in new version of brolib-sml so that we can get bug fixes for LineGap.getLineNumberOfIdx, delete the TextWindow structure (which was previously used to get the start line to draw from), and replace previous usages of TextWindow with TextScroll.getStartLine. This enables us to scroll in a way tailored to the reimplemented TextBuilder (which do not wrap lines or characters) 2025-09-13 05:12:17 +01:00
