Jacode-2.13.4.34

Changes for version 2.13.4.34 - 2026-06-15

  • lib/jacode.pl: rewrite the UTF-8 source self-check on line 2 so that it no longer uses perl 5 only syntax. The previous form embedded the file name with the "baby cart" construct @{[__FILE__]}, which depends on references (and __FILE__ interpolation) and therefore does NOT parse on perl 4.036 -- it caused a compile-time failure that prevented jacode.pl from loading at all on perl 4, contradicting the stated "perl 4.036 through current perl 5" compatibility goal. The regular expression that detects the encoding is unchanged (it still aborts loading unless the file was saved as UTF-8); only the die message was simplified to drop @{[...]} and __FILE__.
  • add t/9060_perl4_baby_cart.t: static guard asserting that lib/jacode.pl contains no @{[ ... ]} baby-cart construct (a perl 5 only idiom), so this perl 4 incompatibility cannot silently return
  • lib/jacode.pl: document the perl 4 safe self-check in POD ("COMPATIBILITY AND WARNINGS" section)
  • lib/jacode.pl: suppress the "Old package separator" deprecation warning that the apostrophe (') separator triggers on Perl 5.38.0+. The separator is kept for Perl 4.036 / 5.005_03 compatibility and is NOT changed to "::". Two BEGIN blocks (gated on $] >= 5.038000, wrapped in eval q{} so they stay inert on Perl 4 / 5.005_03) install a __WARN__ filter before, and restore the caller's handler after, the apostrophe code is compiled. The filter drops only that one message and chains every other warning through to the caller (fail-safe).
  • add t/9030_no_apostrophe_warning.t: assert require/init emits no other warning class, and that the apostrophe-separator warning does not leak on Perl 5.38.0+
  • add t/9040_roundtrip_invariant.t: assert X -> Y -> X round-trip identity for jis/euc/sjis/utf8 over a hiragana/katakana/kanji/fullwidth/halfwidth/ punctuation corpus
  • lib/jacode.pl: document the above warning suppression in POD (new "COMPATIBILITY AND WARNINGS" section)
  • created by INABA Hitoshi
