This is a quick reference to Perl's regular expressions. For full information see perlre and perlop, as well as the "SEE ALSO" section in this document. 本ドキュメントは、Perl の正規表現のクイックリファレンスです。 完全な情報は、perlre と perlop、また、本ドキュメントの "SEE ALSO" セクションを参照してください。 演算子¶

This is complete documentation about all aspects of references. For a shorter, tutorial introduction to just the essential features, see perlreftut. Before release 5 of Perl it was difficult to represent complex data structures, because all references had to be symbolic--and even then it was difficult to refer to a variable instead of a symbol table entry. Perl now not only makes it easier to use

Operator precedence and associativity work in Perl more or less like they do in mathematics. Operator precedence means some operators are evaluated before others. For example, in 2 + 4 * 5, the multiplication has higher precedence so 4 * 5 is evaluated first yielding 2 + 20 == 22 and not 6 * 5 == 30. 演算子の優先順位 とは、他の演算子より先に評価される演算子が あるということです。 例えば、2 + 4 * 5 の場合、乗算が高い優先順位を持っているので、 4 * 5 が先に評価され、結果は 6

perlipc - Perl interprocess communication (signals, fifos, pipes, safe subprocesses, sockets, and semaphores) The basic IPC facilities of Perl are built out of the good old Unix signals, named pipes, pipe opens, the Berkeley socket routines, and SysV IPC calls. Each is used in slightly different situations. Perl uses a simple signal handling model: the %SIG hash contains names or references of use

Along with the Perl interpreter itself, the Perl distribution installs a range of utilities on your system. There are also several utilities which are used by the Perl distribution itself as part of the install process. This document exists to list all of these utilities, explain what they are for and provide pointers to each module's documentation, if appropriate. Perl 配布は、Perl インタプリタ自身と共に、様々なユーテ

This page provides a basic tutorial on understanding, creating and using regular expressions in Perl. It serves as a complement to the reference page on regular expressions perlre. Regular expressions are an integral part of the m//, s///, qr// and split operators and so this tutorial also overlaps with "Regexp Quote-Like Operators" in perlop and "split" in perlfunc. このページでは Perl の正規表現(regular exp

題名¶ Moose::Manual::Attributes - Mooseによるオブジェクトのアトリビュート はじめに¶ Mooseのアトリビュートには多くのプロパティがあります。アトリビュートはおそらくMooseの機能としてはずば抜けて強力で柔軟なものですし、アトリビュートを宣言するだけで強力なクラスを作れます。実際、アトリビュートの宣言しかないクラスを作ることもできます。 アトリビュートは、あるクラスに属するすべてのメンバーが持つプロパティです。たとえば、「Personオブジェクトにはかならず姓と名がある」といえます。また、アトリビュートは省略可能にすることもできるので、「Personオブジェクトの中には社会保障番号を持つものもある（持たないものもある）」ということもできます。 もっとも単純な例では、アトリビュートは（ハッシュのように）読み書き可能な名前付きの値とも考えられます。ただし

Perl provides a mechanism for alternative namespaces to protect packages from stomping on each other's variables. In fact, there's really no such thing as a global variable in Perl. The package statement declares the compilation unit as being in the given namespace. The scope of the package declaration is from the declaration itself through the end of the enclosing block, eval, or file, whichever

Perl is designed to make it easy to program securely even when running with extra privileges, like setuid or setgid programs. Unlike most command line shells, which are based on multiple substitution passes on each line of the script, Perl uses a more conventional evaluation scheme with fewer hidden snags. Additionally, because the language has more builtin functionality, it can rely less upon ext

This document provides an introduction to object-oriented programming in Perl. It begins with a brief overview of the concepts behind object oriented design. Then it introduces several different OO systems from CPAN which build on top of what Perl provides. この文書は Perl でのオブジェクト指向プログラミングを紹介します。 これはオブジェクト指向設計の背後にあるコンセプトの概説から始めます。 それから Perl が提供するものの上に構築されている、 CPAN にあるいくつかの OO システムを紹介します。 By default, P

Variable names in Perl can have several formats. Usually, they must begin with a letter or underscore, in which case they can be arbitrarily long (up to an internal limit of 251 characters) and may contain letters, digits, underscores, or the special sequence :: or '. In this case, the part before the last :: or ' is taken to be a package qualifier; see perlmod. Perl の変数名は様々な形があります。 通常、変数名は英文字か下線で

Does exactly the same thing as exec, except that a fork is done first and the parent process waits for the child process to exit. Note that argument processing varies depending on the number of arguments. If there is more than one argument in LIST, or if LIST is an array with more than one value, starts the program given by the first element of the list with arguments given by the rest of the list

This tutorial describes the use of Perl interpreter threads (sometimes referred to as ithreads). In this model, each thread runs in its own Perl interpreter, and any data sharing between threads must be explicit. The user-level interface for ithreads uses the threads class. このチュートリアルは、Perl インタプリタスレッド(iスレッド(ithreads)と 呼ばれる)の特徴を説明するものです。 このモデルにおいては、それぞれのスレッドはそれ自身の Perl インタプリタで 実行され、スレッド間で共有するデータも明示的

First you need to understand what references are in Perl. See perlref for that. Second, if you still find the following reference work too complicated, a tutorial on object-oriented programming in Perl can be found in perltoot and perltooc. まず最初に、あなたが Perl におけるリファレンスがなんであるかを理解している 必要があります。 perlref を参照してください。 第二に、これから説明するリファレンスの動作が複雑すぎると思うようなら、 Perl におけるオブジェクト指向プログラミングのチュートリアルが perltoot と perltooc

This is an introduction to the use of performance and optimization techniques which can be used with particular reference to perl programs. While many perl developers have come from other languages, and can use their prior knowledge where appropriate, there are many other people who might benefit from a few perl specific pointers. If you want the condensed version, perhaps the best advice comes fr

Not really a function. Returns the value of the last command in the sequence of commands indicated by BLOCK. When modified by the while or until loop modifier, executes the BLOCK once before testing the loop condition. (On other statements the loop modifiers test the conditional first.) 実際は関数ではありません。 BLOCK で示されるコマンド列の最後の値を返します。 while や until ループ修飾子で修飾すると、 ループ条件を調べる前に 1 度、BLOCK を実行します。 (これ以外の実行文は、ル

そして通常は以下のようにして使います: $ua = LWP::UserAgent->new; $response = $ua->request($request); 説明¶ HTTP::Request is a class encapsulating HTTP style requests, consisting of a request line, some headers, and a content body. Note that the LWP library uses HTTP style requests even for non-HTTP protocols. Instances of this class are usually passed to the request() method of an LWP::UserAgent object. HTTP::Request

Perl has two simple, built-in ways to open files: the shell way for convenience, and the C way for precision. The shell way also has 2- and 3-argument forms, which have different semantics for handling the filename. The choice is yours. Perl には、ファイルを開くための 2 つの単純な組み込みの手段があります: 利便性のためのシェル風の方法と、正確性のための C 風の方法です。 シェル風の方法には 2 引数と 3 引数があり、ファイル名の扱いに関して 異なった動作をします。 選択はあなた次第です。 シェル風に開く¶ Perl's open functio

This manual page discusses the syntax and use of character classes in Perl Regular Expressions. A character class is a way of denoting a set of characters, in such a way that one character of the set is matched. It's important to remember that matching a character class consumes exactly one character in the source string. (The source string is the string the regular expression is matched against.)
