Revision history for Perl extension IO::Stty

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.

0.04 Sat Jan 18 2020
   - Switch to EU::MM
   - Address a few deficiencies in the way how the stty() sub processes its arguments
   - Enable testing on Github actions.

0.03 Thu May 6 2010
   - Re-vamp IO::Stty to modern layout
   - stty.txt moved into POD for module
   - stty.pl in docs. Die if no params passed to stty

0.02_01 Tue Mar 23 2010
  - Re-vamp module to Module::Build
  - stty.txt merged into POD so it shows up on CPAN
  - add Changes log
  - basic tests
  - die if no parameters passed to stty
