perlretut - Perl regular expressions tutorial

DESCRIPTION
Part 1: The basics

Simple word matching
Using character classes
Matching this or that
Grouping things and hierarchical matching: 0. Start with the first letter in the string 'a', 1. Try the first alternative in the first group 'abd', 2. Match 'a' followed by 'b'. So far so good, 3. 'd' in the regexp doesn't match 'c' in the string - a dead end. So backtrack two characters and pick the second alternative in the first group 'abc', 4. Match 'a' followed by 'b' followed by 'c'. We are on a roll and have satisfied the first group. Set $1 to 'abc', 5 Move on to the second group and pick the first alternative 'df', 6 Match the 'd', 7. 'f' in the regexp doesn't match 'e' in the string, so a dead end. Backtrack one character and pick the second alternative in the second group 'd', 8. 'd' matches. The second grouping is satisfied, so set $2 to 'd', 9. We are at the end of the regexp, so we are done! We have matched 'abcd' out of the string "abcde"
Extracting matches
Backreferences
Relative backreferences
Named backreferences
Alternative capture group numbering
Position information
Non-capturing groupings
Matching repetitions: 0. Start with the first letter in the string 't', 1. The first quantifier '.*' starts out by matching the whole string ""the cat in the hat"", 2. 'a' in the regexp element 'at' doesn't match the end of the string. Backtrack one character, 3. 'a' in the regexp element 'at' still doesn't match the last letter of the string 't', so backtrack one more character, 4. Now we can match the 'a' and the 't', 5. Move on to the third element '.*'. Since we are at the end of the string and '.*' can match 0 times, assign it the empty string, 6. We are done!
Possessive quantifiers
Building a regexp
Using regular expressions in Perl

perlunicode - Unicode support in Perl

DESCRIPTION

Important Caveats: Safest if you "use feature 'unicode_strings'", Input and Output Layers, You must convert your non-ASCII, non-UTF-8 Perl scripts to be UTF-8, "use utf8" still needed to enable UTF-8 in scripts, UTF-16 scripts autodetected
Byte and Character Semantics
ASCII Rules versus Unicode Rules: When the string has been upgraded to UTF-8, There are additional methods for regular expression patterns
Extended Grapheme Clusters (Logical characters)
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{Title}" and "\p{Titlecase}", "\p{Unicode}", "\p{VertSpace}", "\p{Word}", "\p{XPosix...}"
Comparison of "\N{...}" and "\p{name=...}": [1], [2], [3], [4], [5]
Wildcards in Property Values
User-Defined Character Properties
User-Defined Case Mappings (for serious hackers only)
Character Encodings for Input and Output
Unicode Regular Expression Support Level: [1] "\N{U+...}" and "\x{...}", [2] "\p{...}" "\P{...}". This requirement is for a minimal list of properties. Perl supports these. See R2.7 for other properties, [3] Perl has "\d" "\D" "\s" "\S" "\w" "\W" "\X" "[:prop:]" "[:^prop:]", plus all the properties specified by <https://www.unicode.org/reports/tr18/#Compatibility_Properties>. These are described above in "Other Properties", [4], Regular expression lookahead, [5] "\b" "\B" meet most, but not all, the details of this requirement, but "\b{wb}" and "\B{wb}" do, as well as the stricter R2.3, [6], [7], [8] UTF-8/UTF-EBDDIC used in Perl allows not only "U+10000" to "U+10FFFF" but also beyond "U+10FFFF", [9] Unicode has rewritten this portion of UTS#18 to say that getting canonical equivalence (see UAX#15 "Unicode Normalization Forms" <https://www.unicode.org/reports/tr15>) is basically to be done at the programmer level. Use NFD to write both your regular expressions and text to match them against (you can use Unicode::Normalize), [10] Perl has "\X" and "\b{gcb}". Unicode has retracted their "Grapheme Cluster Mode", and recently added string properties, which Perl does not yet support, [11] see UAX#29 "Unicode Text Segmentation" <https://www.unicode.org/reports/tr29>,, [12] see "Wildcards in Property Values" above, [13] Perl supports all the properties in the Unicode Character Database (UCD). It does not yet support the listed properties that come from other Unicode sources, [14] The only optional property that Perl supports is Named Sequence. None of these properties are in the UCD

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?: If the string's characters are all code point 255 or lower, Perl outputs bytes that match those code points. This is what happens with encoded strings. It can also, though, happen with unencoded strings that happen to be all code point 255 or lower, Otherwise, Perl outputs the string encoded as UTF-8. This only happens with strings you neglected to encode. Since that should not happen, Perl also throws a "wide character" warning in this case
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?

What is an "IV"?
Working with SVs: "SvIV(SV*)" ("IV") and "SvUV(SV*)" ("UV"), "SvNV(SV*)" ("double"), Strings are a bit complicated:, Byte string: "SvPVbyte(SV*, STRLEN len)" or "SvPVbyte_nolen(SV*)", UTF-8 string: "SvPVutf8(SV*, STRLEN len)" or "SvPVutf8_nolen(SV*)", You can also use "SvPV(SV*, STRLEN len)" or "SvPV_nolen(SV*)" to fetch the SV's raw internal buffer. This is tricky, though; if your Perl string is "\xff\xff", then depending on the SV's internal encoding you might get back a 2-byte OR a 4-byte "char*". Moreover, if it's the 4-byte string, that could come from either Perl "\xff\xff" stored UTF-8 encoded, or Perl "\xc3\xbf\xc3\xbf" stored as raw octets. To differentiate between these you MUST look up the SV's UTF8 bit (cf. "SvUTF8") to know whether the source Perl string is 2 characters ("SvUTF8" would be on) or 4 characters ("SvUTF8" would be off)

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?, How can I organize tests into subdirectories and have them run?, PREFIX vs INSTALL_BASE from Module::Build::Cookbook, Generating *.pm files with substitutions eg of $VERSION
Common errors and problems: "No rule to make target `/usr/lib/perl5/CORE/config.h', needed by `Makefile'"
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 '[ndg]make zipdist'?
XS: How do 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?, XSMULTI, Separate directories, Bootstrapping

DESIGN

MakeMaker object hierarchy (simplified)
MakeMaker object hierarchy (real)
The MM_* hierarchy

Obtaining and installing libnet

What is libnet ?
Which version of perl do I need ?
What other modules do I need ?
What machines support libnet ?
Where can I get the latest libnet release

Using Net::FTP

How do I download files from an FTP server ?
How do I transfer files in binary mode ?
How can I get the size of a file on a remote FTP server ?
How can I get the modification time of a file on a remote FTP server ?
How can I change the permissions of a file on a remote server ?
Can I do a reget operation like the ftp command ?
How do I get a directory listing from an FTP server ?
Changing directory to "" does not fail ?
I am behind a SOCKS firewall, but the Firewall option does not work ?
I am behind an FTP proxy firewall, but cannot access machines outside ?
My ftp proxy firewall does not listen on port 21
Is it possible to change the file permissions of a file on an FTP server ?
I have seen scripts call a method message, but cannot find it documented ?
Why does Net::FTP not implement mput and mget methods

Using Net::SMTP

Why can't the part of an Email address after the @ be used as the hostname ?
Why does Net::SMTP not do DNS MX lookups ?
The verify method always returns true ?

Debugging scripts

How can I debug my scripts that use Net::* modules ?

Pod::Perldoc::GetOptsOO - Customized option parser for Pod::Perldoc

SYNOPSIS
DESCRIPTION: Call Pod::Perldoc::GetOptsOO::getopts($object, \@ARGV, $truth), Given -n, if there's a opt_n_with, it'll call $object->opt_n_with( ARGUMENT ) (e.g., "-n foo" => $object->opt_n_with('foo'). Ditto "-nfoo"), Otherwise (given -n) if there's an opt_n, we'll call it $object->opt_n($truth) (Truth defaults to 1), Otherwise we try calling $object->handle_unknown_option('n') (and we increment the error count by the return value of it), If there's no handle_unknown_option, then we just warn, and then increment the error counter

VERSION
SYNOPSIS
DESCRIPTION
METHODS

Class Methods
Rules data structure: By default, all tests are eligible to be run in parallel. Specifying any of your own rules removes this one, "First match wins". The first rule that matches a test will be the one that applies, Any test which does not match a rule will be run in sequence at the end of the run, The existence of a rule does not imply selecting a test. You must still specify the tests to run, Specifying a rule to allow tests to run in parallel does not make the run in parallel. You still need specify the number of parallel "jobs" in your Harness object
