`InteractivePrinter::print_snip` computes the snip separator width as
`term_width - panel_count - snip_left_count - title_count`. At `--terminal-width 1`
the panel is disabled and `title_count == 2`, so the subtraction underflows
`usize` (release has no overflow-checks, so it wraps to ~usize::MAX); `str::repeat`
then aborts with "capacity overflow" whenever a snip separator is emitted (two or
more disjoint line ranges, or a diff gap) — which the default style does.
Use `saturating_sub` for the repeat counts so they clamp to 0 instead of
underflowing. Added an integration test.
Every shell completion script (bash, zsh, fish, PowerShell) shells out
to bat to enumerate languages/themes for tab completion candidates. If
the user has wired bat into LESSOPEN (e.g. LESSOPEN='|-bat -f -pp %s'),
bat's normal pager auto-detection can engage when stdout looks like a
terminal at completion time and reflect ANSI escape sequences back into
the candidate list. The result is the issue's reproducer: tab completion
expands 'Per' to '\033[38;2;248;248;242mPerl' instead of 'Perl'.
The list-languages/list-themes calls are always meant to be machine-
readable, so they should never page. Pass --no-paging explicitly to
every bat invocation inside the four completion files. The flag is the
public alias for --paging=never (already documented in bat --help) and
is the same form completion scripts elsewhere in the codebase use.
Touches the four completion files only; no production code changes.
The previous awk script in `bat.zsh.in` split each line of
`bat --list-languages` on `:` or `,` and emitted every field as a
completion candidate, including the second column. That column lists
file matchers, which can be plain extensions (`rs`), globs (`*.rs`),
absolute paths (`/etc/profile`), or filenames (`Containerfile`). None
of those parse as `-l` arguments, so completing them produces
`unknown syntax` errors.
Switch to splitting on `:` only and emit the language name as the
completion value with the file-matcher list as its description, which
matches the bash completion's behavior.
Closes#3735.
Add a .cargo/config.toml that sets target-feature=+crt-static for the
i686, x86_64, and aarch64 MSVC targets so bat.exe no longer depends on
the vcruntime DLL. Mirrors the fix applied to fd in sharkdp/fd#1891.
Closes#3634
Add extensionless regression test files for tclsh, wish, and expect
shebangs so syntect bumps don't silently break first-line detection.
Move changelog entry from Features to Syntaxes per reviewer suggestion.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add first_line_match to the Tcl syntax definition via a patch file,
enabling automatic Tcl highlighting for scripts with tclsh, wish,
or expect shebangs.
Fixes#3513
Add documentation showing how to erase the fish abbreviations for
--help and -h, since the dash-prefixed names make removal non-obvious.
The key is using -- before the abbreviation name to prevent fish from
interpreting it as a flag.
Closes#3536
The i686 .deb package declared its architecture as "i686", which
Debian does not recognize. Debian uses "i386" for 32-bit x86,
matching the convention already used by the other targets (arm64,
armhf, amd64).
Closes#3611
Control characters displayed in caret notation (e.g. ^@ for NUL)
occupy 2 terminal columns, but the width calculation treated them
as 0-width. Add a char_width() helper that returns 2 for control
characters, fixing incorrect line wrapping with --binary=as-text.
Fixes#3631
