Enhancement of new `fill` command (#7846) to handle content including ANSI escape codes for formatting or multi-code-point Unicode grapheme clusters. In both of these cases, the content is (many) bytes longer than its visible length, and `fill` was counting the extra bytes so not adding enough fill characters. # Description This script: ```rust # the teacher emoji `\u{1F9D1}\u{200D}\u{1F3EB}` is 3 code points, but only 1 print position wide. echo "This output should be 3 print positions wide, with leading and trailing `+`" $"\u{1F9D1}\u{200D}\u{1F3EB}" | fill -c "+" -w 3 -a "c" echo "This output should be 3 print positions wide, with leading and trailing `+`" $"(ansi green)a(ansi reset)" | fill -c "+" -w 3 -a c echo "" ``` Was producing this output: ```rust This output should be 3 print positions wide, with leading and trailing `+` 🧑🏫 This output should be 3 print positions wide, with leading and trailing `+` a ``` After this PR, it produces this output: ```rust This output should be 3 print positions wide, with leading and trailing `+` +🧑🏫+ This output should be 3 print positions wide, with leading and trailing `+` +a+ ``` # User-Facing Changes Users may have to undo fixes they may have introduced to work around the former behavior. I have one such in my prompt string that I can now revert. # Tests + Formatting Don't forget to add tests that cover your changes. -- Done Make sure you've run and fixed any issues with these commands: - [x] `cargo fmt --all -- --check` to check standard code formatting (`cargo fmt --all` applies these changes) - [x] `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A clippy::needless_collect` to check that you're using the standard code style - [x] `cargo test --workspace` to check that all tests pass # After Submitting `fill` command not documented in the book, and it still talks about `str lpad/rpad`. I'll fix. Note added dependency on a new library `print-positions`, which is an iterator that yields a complete print position (cluster + Ansi sequence) per call. Should this be vendored?
