Revision history for Perl extension IO::Stty
0.08 Thu Apr 02 2026
Bug fixes:
- Fix Perl 5.8 compatibility: replace // (defined-or) operator with
ternary equivalent. The // operator requires Perl 5.10 but
MIN_PERL_VERSION is 5.008. (GH #28, GH #29, PR #30, PR #31)
- Implement crterase alias (was documented but never coded) and
correct dec/crt combination documentation to match actual behavior.
(PR #33)
- Add exta, extb, and 134.5 baud rate aliases that were documented
but silently rejected. (PR #32)
- Use _POSIX_VDISABLE for disabling special characters instead of
hardcoded 0, fixing 'undef'/'^-' on macOS/BSD where VDISABLE is
255. Also fix sane/cooked combos to use 'undef' for eol. (PR #37)
- Handle VEOF/VMIN and VEOL/VTIME shared cc slots on Solaris/SVR4
systems where these overlap in the termios cc array. (GH #38,
PR #42)
- Fix _cc_to_hat() to use only _POSIX_VDISABLE, not hardcoded 0/255,
preventing wrong <undef> display on Linux and macOS. (PR #46)
- Add missing igncr flag to -a display output. (PR #50)
- Handle getattr() failure by returning undef instead of silently
continuing with zeroed flags. Return setattr() result so callers
can detect failure. (PR #36)
- Fix broken $private_subs reference in t/99-pod-coverage.t and
remove duplicate echok in sane combo expansion. (PR #34)
Improvements:
- Add evenp, oddp, parity, cbreak, and litout combination aliases
matching GNU stty behavior. (PR #35)
- Add 'speed' query parameter to return just the output baud rate,
matching GNU stty behavior. (PR #51)
- Document iexten as a settable local flag in POD. (PR #36)
- Document AI Policy
Maintenance:
- Add provides metadata to Makefile.PL for correct CPAN indexing,
using MM->parse_version() for dynamic version extraction. (PR #47,
PR #53)
- Add strict/warnings to boilerplate test files. (PR #34)
- Clarify in CLAUDE.md that README.md and MANIFEST are generated
files and that release prep is human-only. (PR #53, PR #54)
0.07 Sun Mar 22 2026
Bug fixes:
- Fix "Use of uninitialized value" warning in stty.pl when stdin is
not a terminal. stty() returns undef when isatty fails; the script
now guards with defined() before comparing. (PR #25)
- Fix broken C<-icanon> POD formatting and add missing iexten to sane
combination documentation. Replace "Needs documentation" stub with
proper docs for show_me_the_crap(). (PR #26)
Improvements:
- Show min and time values in -a output. These are critical for
non-canonical (raw/cbreak) mode users and match GNU stty behavior.
Also adds functional tests for hat-notation control char assignment,
undef/^- char disabling, and min/time setting. (PR #27)
Maintenance:
- Declare MIN_PERL_VERSION 5.008 in Makefile.PL to prevent CPAN from
attempting installation on too-old perls. (PR #25)
- Add IO::Pty as a test recommends in cpanfile for better test
coverage on CPAN testers and CI. (PR #25)
- Regenerate README.md from updated POD. (PR #26)
0.06 Fri Mar 20 2026
Bug fixes:
- Fix show_me_the_crap() emitting "speed baud" (empty speed) when
getospeed() returns a value not mapped to any standard POSIX B*
constant (e.g. on OpenBSD). Now falls back to the raw numeric value.
(GH #19, PR #23)
- Display ispeed separately in -a output when it differs from ospeed,
using the same raw-numeric fallback for unmapped values. (PR #23)
- Fix ispeed test failure on Linux ptys where the kernel normalises
ispeed to match ospeed during tcsetattr(). Set both speeds in a
single stty() call to avoid the normalisation window.
(GH #16, PR #17, PR #21)
- Replace // (defined-or) operator in tests with ternary equivalent
for Perl 5.8 compatibility. (GH #20, PR #24)
Improvements:
- Recognize --version flag in stty.pl; previously only -v and bare
"version" were matched despite the POD documenting --version.
(PR #15)
- Modernize scripts/stty.pl: add strict/warnings, lexical variables,
and a portable shebang. (PR #15)
Maintenance:
- Harden ispeed baud rate test against Linux pty kernel normalisation.
(GH #16, PR #21)
0.05 Wed Mar 19 2026
Bug fixes:
- Fix broken single-arg baud rate setting. Passing a numeric rate like
"9600" as the sole argument now correctly sets both ispeed and ospeed.
The single-arg code path had two independent if/else blocks instead of
one if/elsif chain, so the baud rate was silently never applied. (PR #11)
- Replace unsafe symbolic dereference &{"POSIX::B" . $input} in the
ospeed/ispeed handlers with a static %BAUD_RATES hash lookup. The old
pattern was dead code in all public releases (use strict prevented it
from running) but is now properly fixed. Unknown rates produce a
warning instead of dying. (PR #7, PR #11)
Improvements:
- Add modern baud rates B57600, B115200, and B230400 with eval guards
for platforms that lack them. (PR #9)
- Render control characters in hat notation (e.g. ^C, ^D) in -a
output instead of raw numeric values. (PR #8)
- Add special character value parsing for stty(): accept hat notation
(^C), hexadecimal (0x03), octal (003), decimal, and single literal
characters when setting control char values. (PR #6)
Maintenance:
- Add functional pty-based test suite using IO::Pty covering flag
toggling, -g/-a roundtrips, raw/cooked/sane modes, baud rate setting,
and control character assignment. (PR #10)
- Add baud rate regression tests with a decoy-function guard against
reintroduction of symbolic dereference. (PR #7)
- Modernize CI: replace three separate workflow files with unified
testsuite.yml using current GitHub Actions. (GH #12, PR #13)
- Update stale GitHub URLs (http to https) and modernize CPAN metadata
to META spec v2 with TEST_REQUIRES. (PR #14)
- Add cpanfile for CI dependency management.
- Re-generate README from Stty.pm.
- Apply Perl::Tidy formatting.
