Front page | perl.perl5.porters | Postings from May 2013 perl 5.18.0 is now available! From:Ricardo Signes Date: May 18, 2013 13:35 Subject: perl 5.18.0 is now available! Message It is an error to divide people into the living and the dead: there are people who are dead-alive, and people who are alive-alive. The dead-alive also write, walk, speak, act. But they make no mistakes; only machines make no mistakes, and they produce only dead things. The alive-alive are constantly in error, in search, in questions, in torment. -- Yevgeny Zamyatin We are excited to announce perl v5.18.0, the first stable release of v +ersion 18 of Perl 5.

    Do you mind telling us what is actually new in this release? Thanks.

      See perldelta.

      Most notable changes (imo):

      • The seed used by Perl's hash function is now random.
      • Lexical subroutines
      • given now aliases the global $_
      • Lexical $_ is now experimental

        What does 'lexical $_ is now experimental' mean? Is something like this still doable?

        while(<SOMEHANDLE>) { chomp; my $string = "hello" .$_; print $string; }

        Still work?

      Off the top of my head, the big ones are:

      * Lexical subroutines! package Foo { my sub bar { ... } } Now you can use bar() inside Foo, but there is no way to access that from the outside. There's also state subs, in case you ever seen those.

      * Regexp code blocks that actually work! /(?{...})/ and /(??{...})/ now work exactly as you'd expect them to. Before it was a buggy pain.

      * Character class set operations! This is my personal favorite. Basically, now you can write /(?[ \p{Math} & \p{Symbol} ])+/ where before you had to do /((?=\p{Math})\p{Symbol})+/. There's other operations too, like + or -.

    ouch I see lots of problems on cygwin. Does not build with make -j 3 but maybe this is expected... Still make test fails for me. Some seem to be issues with file perms but the re ones seem worrisome. :/

    make test output gives:

    hth --steph Failed 26 tests out of 2336, 98.89% okay. ../cpan/Encode/t/CJKT.t ../cpan/Encode/t/at-cn.t ../cpan/Encode/t/perlio.t ../cpan/Pod-Simple/t/corpus.t ../cpan/Pod-Simple/t/pulltitl.t ../cpan/Text-Tabs/t/Tabs-ElCid.t ../cpan/Text-Tabs/t/Wrap-JLB.t ../cpan/podlators/t/man.t ../ext/XS-APItest/t/call_checker.t ../lib/File/stat.t io/shm.t op/bop.t op/taint.t op/threads.t re/fold_grind.t re/pat_rt_report.t re/pat_rt_report_thr.t re/regex_sets_compat.t re/regexp.t re/regexp_noamp.t re/regexp_notrie.t re/regexp_qr.t re/regexp_qr_embed.t re/regexp_qr_embed_thr.t re/regexp_trielist.t uni/overload.t

    a rebase at a fixed address should probably be done just after the build... as some dlls gave a fork error. Most tests could use a "spawn" instead of fork-exec. Please p5p give us a spawn this would be useful on cygwin. These days I maintain a rebase db for all my perls. A given dll gets the same base address. I don't use the cygwin rebase db, it does not fit my needs for many perls and a third of cpan installed ;)
