b73117d075 add failing test for 'dj' motion, and progress reimplementing 'MakeNormalDelete.deleteLine' 2025-09-25 06:11:36 +01:00
d25a06a9ed progress reimplementing 'MakeNormalDelete.deleteLine 2025-09-25 06:04:11 +01:00
11015dfa9e add two more test cases for 'dj' motion that were failing when added, and modify 'MakeNormalDelete.deleteLineDown' to handle them 2025-09-25 05:28:13 +01:00
e24230834e rename existing 'MakeNormalDelete.deleteLine' function to 'MakeNormalDelete.deleteLineDown', make 'dj' and 'ydj' commands use the renamed function, and add a new 'MakeNormalDelete.deleteLine' function (which has no implementation yet). We do this because we want to distinguish between 'dd' and 'dj' commands, allowing 'dd' to delete to the end of the file despite any count, while stoppinhg 'dj' from deleting the file when on the last line. 2025-09-25 04:56:25 +01:00
1255238d6c pass failing tests for 'dj' motion 2025-09-24 19:32:31 +01:00
2076d25653 begin reimplementing 'MakeNormalDelete.deleteLine' function 2025-09-24 17:58:37 +01:00
80078196e0 if 'MakeNormalDelete.deleteLine' deletes to the end of the file such that there is no newline at the end, then append a newline. This makes one of the tests we have pass. 2025-09-24 13:05:13 +01:00
222a9aa43c fix 'MakeNormalDelete.removeChr' by accounting for case when we are deleting from last line but the last line does not end with its own newline 2025-09-24 09:46:28 +01:00
e70aab8952 add another failing test for 'dl' motion 2025-09-24 09:07:26 +01:00
95393e1e13 amand MakeNormalDelete.removeChr function (which is used by 'x' and 'dh' commands) to pass test, which checks that cursorIdx does not fall on newline-after-chr after deletion 2025-09-24 09:02:33 +01:00
c500704f04 add failing tests for 'dj' motion 2025-09-24 08:54:13 +01:00
a8bc405727 add failing test for 'dl' motion 2025-09-24 07:58:45 +01:00
00ab086257 remove code related to appending newlines in 'MakeNormalDelete', as we have decided that we allow files which do not end in newlines as well as files that do 2025-09-24 07:18:11 +01:00
51a7c358ca found bug in '0' motion, added test for it, and fixed it as well 2025-09-23 16:05:23 +01:00
9a15b1715a pass all tests for 'j' motion 2025-09-23 15:30:28 +01:00
95a4f109bd progress reimplementing 'j' motion to pass new tests 2025-09-23 15:22:49 +01:00
c3ca8dddf4 add additional failing unit test for 'j' motion 2025-09-23 13:30:54 +01:00
109fda187a add a new failing test, and modify 'TestUtils.init' function (which takes a string and returns an AppType.app_type) so that it does not automatically add a newline to the end of strings. (This modification required changing the strings in some tests, as those strings did not have newlines at the end but the test assumes they did.) 2025-09-23 13:18:36 +01:00
2376ae07b5 fix tests which broke due to a design decision (how to handle newlines) 2025-09-23 12:15:14 +01:00
fcc8c8085a reimplement 'G' motion so that it follows new rule (cursor goes to second-last chr if last chr is a newline preceded by a non-newline, but goes to last chr otherwise) 2025-09-23 11:57:19 +01:00
5d20b81bcc adjust functor to move by dfa so that we cannot go to the last char of the file if (last char is a newline and is preceded by a non-newline), but otherwise we can go to the last char of the file. 2025-09-23 11:47:25 +01:00
5fded45303 remove redundant test 2025-09-23 11:11:33 +01:00
4f20379219 take care of a few tests after refactoring/making a different design decision 2025-09-23 11:04:47 +01:00
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
8931d4d071 fix minor compilation error introduced in previous commit 2025-09-23 09:29:02 +01:00
ec462a4df7 remove special case from 'k' motion: the exact semantics we want for trailing newlines at the end of a file are currently a bit unclear and require exploration 2025-09-23 09:27:13 +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
505521f5e2 minor cosmetic change 2025-09-23 09:04:18 +01:00
6be1d48b02 add test for 'k' motion: when file ends with two newlines and cursor is on newline_1 in the pattern (char -> newline_1 -> newline_2), we should be able to move up by a line 2025-09-23 09:00:50 +01:00
c9365076ad handle special case with 'k' motion: when file ends with \n\n and cursor is on first \n: we should be able to move upwards from here too 2025-09-23 08:54:19 +01:00
494d56e997 add two new tests to check that 'w' motion does not let cursor go to last newline in file, but does let cursor go to second-last newline 2025-09-23 08:20:40 +01:00
79d232df7a amend very minor bug: when looping through DFA and hitting a 'final state', we let the next chr afterwards handle the start state, but we want the current char to handle the start state instead, as this matches vim's behaviour 2025-09-23 07:36:51 +01:00
0b0d5268fc handle edge case when deleting by DFA: when we are deleting to the end of the file and if cursor is on first character after newline, then we also want to delete preceding newline too. Or else we will end up with two newlines at the end of the file, which is not what we want. 2025-09-23 07:18:58 +01:00
ec10f3e025 tiny amount of formatting 2025-09-23 07:04:41 +01:00
9174e4923c don't deleteByDfa when buffer's length is 1, because that would mean that we would be deleting last newline in file 2025-09-23 07:04:20 +01:00
02ada5765b improve 'MakeNormalDelete.deleteByDfa' function by refraining from deleting the unix-style line ending, if DFA takes us past the ending 2025-09-23 06:09:03 +01:00

e3148e6ac1 when deleting using a DFA motion, make sure we have a linebreak at the end so that we still have unix-style line endings as an invariant 2025-09-22 12:41:33 +01:00
351f7e9bf9 fix edge case with 'd$' motion: if deleting to end of file, we need to append two newlines 2025-09-22 12:28:08 +01:00
d3c6031b19 pull in new version of brolib-sml, which has bug fixes for line_gap.sml's 'lineNumberToIdx' function 2025-09-22 10:30:00 +01:00
