fix bug with ViDlrDfa.next: we previously did not consider the case of cursor starts on a line containing nothing but a blank \n newline. We consider this now, returning the same index when it occurs.

when constructing SEARCH message, include time in the message as well. This will enable us to ignore any messages when we have a 'later' state available.

add backtract functionality for range search as well
Humza Shahid2025-09-06 23:05:11 +01:00

add backtracking functionality to search; when we find a partial but incomplete match, we want to start looking for a match from ('idx + 1'), where 'idx' is the index we started this failed search at.

handle edge cases in line-break removal function ('J' command). If the newline we find is the last character in the file, we don't delete it, because of Unix convention that text files always end with newlines.
Humza Shahid2025-09-06 10:05:06 +01:00

add a function to remove line breaks: the equivalent of Vim's 'J' command.

replace redundant code (which matched semantics of a newly added function) with a function call.

fix minor bug when deleting around (with motion like da( or da< or da) or da>). The bug was that, if the last character we delete with the highest index is also the last character at the end of this line, we deleted the range properly but placed the cursor at a linebreak. In this case, the cursor is meant to be a single character before the line break, and after this commit, we have this desired behaviour.

in normal mode, when we receive an event which we don't want to handle (like enter), we clear the app's mode and command history instead of simply returning the same app unmodified. This fixes a bug: say we pres 'f' to go to a character and then press enter. Before this commit, pressing a character after that 'enter' will go to that character. This is contrary to Vim, which resets the command history on an invalid command, and now we reset the command history too.

bug fix when yanking or deleting inside a word (we should not clip 'high' value, and we should search for end of word strictly); this handles cases like when we only have one character in the buffer, or an empty buffer
Humza Shahid2025-09-06 01:12:59 +01:00
b9332bcd94
fix bugs related to deleting ('dge' and 'dgE' motions should also delete the letter which the cursor is currently at, and now they do)
Humza Shahid2025-09-06 00:02:37 +01:00

refactoring, and fix bug in 'y^' motion. (When cursor is after first-non-space-character, copy from first-non-space-character to cursor. Otherwise, copy spaces at beginning until first-non-space-character.)

because GLFW at this time has clipboard bugs on Wayland (setting clipboard string), we print out whenever the shell receives a 'yank' message indicating for GLFW to copy. This will let us test that the correct string is yanked.

fix visual bug resulting from 'TextBuilder.buildTextStringSearch' function. When we have a search string 'abc' and a file 'abcabc', there are two matches and it should also look like there are two matches, but it did not look like there were two matches prior to this commit. This commit fixes that by advancing the search position before adding to the text accumulator.
