DESCRIPTION
Awk Traps
C/C++ Traps
Sed Traps
Shell Traps
Perl Traps
Perl4 to Perl5 Traps

Discontinuance, Deprecation, and BugFix traps, Parsing Traps, Numerical Traps, General data type traps, Context Traps - scalar, list contexts, Precedence Traps, General Regular Expression Traps using s///, etc, Subroutine, Signal, Sorting Traps, OS Traps, DBM Traps, Unclassified Traps

Discontinuance, Deprecation, and BugFix traps

Symbols starting with "_" no longer forced into main, Double-colon valid package separator in variable name, 2nd and 3rd args to splice() are now in scalar context, Can't do goto into a block that is optimized away, Can't use whitespace as variable name or quote delimiter, while/if BLOCK BLOCK gone, ** binds tighter than unary minus, foreach changed when iterating over a list, split with no args behavior changed, -e behavior fixed, push returns number of elements in resulting list, Some error messages differ, split() honors subroutine args, Bugs removed

Parsing Traps

Space between . and = triggers syntax error, Better parsing in perl 5, Function parsing, String interpolation of $#array differs, Perl guesses on map, grep followed by { if it starts BLOCK or hash ref

Numerical Traps

Formatted output and significant digits, Auto-increment operator over signed int limit deleted, Assignment of return values from numeric equality tests doesn't work, Bitwise string ops

General data type traps

Negative array subscripts now count from the end of array, Setting $#array lower now discards array elements, Hashes get defined before use, Glob assignment from localized variable to variable, Assigning undef to glob, Changes in unary negation (of strings), Modifying of constants prohibited, defined $var behavior changed, Variable Suicide

Context Traps - scalar, list contexts

Elements of argument lists for formats evaluated in list context, caller() returns false value in scalar context if no caller present, Comma operator in scalar context gives scalar context to args, sprintf() prototyped as ($;@)

Precedence Traps

LHS vs. RHS of any assignment operator, Semantic errors introduced due to precedence, Precedence of assignment operators same as the precedence of assignment, open requires parentheses around filehandle, $: precedence over $:: gone, Precedence of file test operators documented, keys, each, values are regular named unary operators

General Regular Expression Traps using s///, etc.

s'$lhs'$rhs' interpolates on either side, m//g attaches its state to the searched string, m//o used within an anonymous sub, $+ isn't set to whole match, Substitution now returns null string if it fails, s`lhs`rhs` is now a normal substitution, Stricter parsing of variables in regular expressions, m?x? matches only once, Failed matches don't reset the match variables

Subroutine, Signal, Sorting Traps

Barewords that used to look like strings look like subroutine calls, Reverse is no longer allowed as the name of a sort subroutine, warn() won't let you specify a filehandle

OS Traps

SysV resets signal handler correctly, SysV seek() appends correctly

Interpolation Traps

@ always interpolates an array in double-quotish strings, Double-quoted strings may no longer end with an unescaped $, Arbitrary expressions are evaluated inside braces within double quotes, $$x now tries to dereference $x, Creation of hashes on the fly with eval "EXPR" requires protection, Bugs in earlier perl versions, Array and hash brackets during interpolation, Interpolation of \$$foo{bar}, qq() string passed to eval will not find string terminator

DBM Traps

Perl5 must have been linked with same dbm/ndbm as the default for dbmopen(), DBM exceeding limit on the key/value size will cause perl5 to exit immediately

Unclassified Traps

require/do trap using returned value, split on empty string with LIMIT specified

perlunicode - Unicode support in Perl

DESCRIPTION
Important Caveats

Safest if you "use feature 'unicode_strings'", Input and Output Layers, use utf8 still needed to enable UTF-8/UTF-EBCDIC in scripts, BOM-marked scripts and UTF-16 scripts autodetected, use encoding needed to upgrade non-Latin-1 byte strings

Byte and Character Semantics
Effects of Character Semantics
Unicode Character Properties

\p{All}, \p{Alnum}, \p{Any}, \p{ASCII}, \p{Assigned}, \p{Blank}, \p{Decomposition_Type: Non_Canonical} (Short: \p{Dt=NonCanon}), \p{Graph}, \p{HorizSpace}, \p{In=*}, \p{PerlSpace}, \p{PerlWord}, \p{Posix...}, \p{Present_In: *} (Short: \p{In=*}), \p{Print}, \p{SpacePerl}, \p{VertSpace}, \p{Word}, \p{XPosix...}

perlunifaq - Perl Unicode FAQ

Q and A
perlunitut isn't really a Unicode tutorial, is it?
What character encodings does Perl support?
Which version of perl should I use?
What about binary data, like images?
When should I decode or encode?
What if I don't decode?
What if I don't encode?
Is there a way to automatically decode or encode?
What if I don't know which encoding was used?
Can I use Unicode in my Perl sources?
Data::Dumper doesn't restore the UTF8 flag; is it broken?
Why do regex character classes sometimes match only in the ASCII range?
Why do some characters not uppercase or lowercase correctly?
How can I determine if a string is a text string or a binary string?
How do I convert from encoding FOO to encoding BAR?
What are decode_utf8 and encode_utf8?
What is a "wide character"?
INTERNALS
What is "the UTF8 flag"?
What about the use bytes pragma?
What about the use encoding pragma?
What is the difference between :encoding and :utf8?
What's the difference between UTF-8 and utf8?
I lost track; what encoding is the internal format really?

perluniprops - Index of Unicode Version 6.0.0 properties in Perl

DESCRIPTION
Properties accessible through \p{} and \P{}

Single form (\p{name}) tighter rules:, white space adjacent to a non-word character, underscores separating digits in numbers, Compound form (\p{name=value} or \p{name:value}) tighter rules:, Obsolete, Stabilized, Deprecated, * is a wild-card, (\d+) in the info column gives the number of code points matched by this property, D means this is deprecated, O means this is obsolete, S means this is stabilized, T means tighter (stricter) name matching applies, X means use of this form is discouraged

\p{Canonical_Combining_Class=Attached_Below_Left}, \p{Joining_Type=Left_Joining}

Properties not accessible through \p{} and \P{}
Unicode regular expression properties that are NOT accepted by Perl

Expands_On_NFC (XO_NFC), Expands_On_NFD (XO_NFD), Expands_On_NFKC (XO_NFKC), Expands_On_NFKD (XO_NFKD), Grapheme_Link (Gr_Link), Jamo_Short_Name (JSN), Script=Katakana_Or_Hiragana (sc=Hrkt)

Updated Modules

release 1.94_57, bugfix: treat modules correctly that are deprecated in perl 5.12, bugfix: RT #57482 and #57788 revealed that configure_requires implicitly assumed build_requires instead of normal requires. (Reported by Andrew Whatson and Father Chrysostomos respectively), testfix: solaris should run the tests without expect because (some?) solaris have a broken expect, testfix: run tests with cache_metadata off to prevent spill over effects from previous test runs

Changes to Existing Documentation

Selected Bug Fixes

Timely cleanup of SVs that are cloned into a new thread but then discovered to be orphaned (i.e. their owners are -not- cloned) (e42956), Don't accidentally clone lexicals in scope within active stack frames in the parent when creating a child thread (RT #73086) (05d04d), Avoid loading feature.pm when 'no 5.13.2;' or similar is encountered (faee19), Trap invalid use of SvIVX on SVt_REGEXP when assertions are on (e77da3), Don't stamp on $DB::single, $DB::trace and $DB::signal if they already have values when $^P is assigned to (RT #72422) (4c0f30), chop now correctly handles perl's extended UTF-8 (RT #73246) (65ab92), Defer signal handling when shared SV locks are held to avoid deadlocks (RT #74868) (65c742), glob() no longer crashes when %File::Glob:: is empty and CORE::GLOBAL::glob isn't present (4984aa), perlbug now always permits the sender address to be changed before sending - if you were having trouble sending bug reports before now, this should fix it, we hope (e6eb90), Overloading now works properly in conjunction with tied variables. What formerly happened was that most ops checked their arguments for overloading before checking for magic, so for example an overloaded object returned by a tied array access would usually be treated as not overloaded (RT #57012) (6f1401, ed3b9b, 6a5f8c .. 24328f), Independently, a bug was fixed that prevented $tied->() from always calling FETCH correctly (RT #8438) (7c7501)

What's the minimum perl version required to run Archive::Tar?, Isn't Archive::Tar slow?, Isn't Archive::Tar heavier on memory than /bin/tar?, Can you lazy-load data instead?, How much memory will an X kb tar file need?, What do you do with unsupported filetypes in an archive?, I'm using WinZip, or some other non-POSIX client, and files are not being extracted properly!, How do I extract only files that have property X from an archive?, How do I access .tar.Z files?, How do I handle Unicode strings?

ExtUtils::MakeMaker::Config - Wrapper around Config.pm

SYNOPSIS
DESCRIPTION

ExtUtils::MakeMaker::FAQ - Frequently Asked Questions About MakeMaker

DESCRIPTION
Module Installation

How do I install a module into my home directory?, How do I get MakeMaker and Module::Build to install to the same place?, How do I keep from installing man pages?, How do I use a module without installing it?, PREFIX vs INSTALL_BASE from Module::Build::Cookbook

Philosophy and History

Why not just use <insert other build config tool here>?, What is Module::Build and how does it relate to MakeMaker?, pure perl. no make, no shell commands, easier to customize, cleaner internals, less cruft

Module Writing

How do I keep my $VERSION up to date without resetting it manually?, What's this META.yml thing and how did it get in my MANIFEST?!, How do I delete everything not in my MANIFEST?, Which tar should I use on Windows?, Which zip should I use on Windows for '[nd]make zipdist'?

XS

How to I prevent "object version X.XX does not match bootstrap parameter Y.YY" errors?, How do I make two or more XS files coexist in the same directory?

Module::Build::Cookbook - Examples of Module::Build Usage

DESCRIPTION
BASIC RECIPES
Installing modules that use Module::Build
Modifying Config.pm values
Installing modules using the programmatic interface
Installing to a temporary directory
Installing to a non-standard directory
Installing in the same location as ExtUtils::MakeMaker
Running a single test file
ADVANCED RECIPES
Making a CPAN.pm-compatible distribution
Changing the order of the build process
Adding new file types to the build process
Adding new elements to the install process
EXAMPLES ON CPAN
SVN-Notify-Mirror

1. Using auto_features, I check to see whether two optional modules are available - SVN::Notify::Config and Net::SSH;, 2. If the S::N::Config module is loaded, I automatically generate test files for it during Build (using the PL_files property), 3. If the ssh_feature is available, I ask if the user wishes to perform the ssh tests (since it requires a little preliminary setup);, 4. Only if the user has ssh_feature and answers yes to the testing, do I generate a test file
