此模块的目的是支持文件路径操作（通常称为“文件名”，但不能和文件内容混为一谈，或 者是 Perl 的文件句柄），如连接一些目录和文件名为一个单一的路径，或确定是否是根 路径。

This project is attempting to build an entire AWS SDK from the information that is stored in other AWS SDKs. Other AWS SDKs have a "data-driven" approach, meaning that the definitions for the method calls are stored in a data structure describing input and output parameters. The project is actually generating all of it's classes from botocore.

Pegex is an Acmeist parser framework. It allows you to easily create parsers that will work equivalently in lots of programming languages! The inspiration for Pegex comes from the parsing engine upon which the postmodern programming language Perl 6 is based on. Pegex brings this beauty to the other justmodern languages that have a normal regular expression engine available. Pegex gets it name by combining Parsing Expression Grammars (PEG), with Regular Expessions (Regex). That's actually what Pegex does. PEG is the cool new way to elegantly specify recursive descent grammars. The Perl 6 language is defined in terms of a self modifying PEG language called Perl 6 Rules. Regexes are familiar to programmers of most modern programming languages. Pegex defines a simple PEG syntax, where all the terminals are regexes. This means that Pegex can be quite fast and powerful. Pegex attempts to be the simplest way to define new (or old) Domain Specific Languages (DSLs) that need to be used in several programming languages and environments. Things like JSON, YAML, Markdown etc. It also great for writing parsers/compilers that only need to work in one language.

The Penguin module provides a framework within which a user on one host electronically signs a piece of Perl code, sends it to another host where the signature is checked and the code is executed with privileges that are particular to that user.

Modules that provide OS-specific behaviors often need to know if the current operating system matches a more generic type of operating systems. For example, 'Linux' is a type of 'Unix' operating system and so is 'FreeBSD'. This module provides a mapping between an operating system name as given by $^O and a more generic type.

This module is an extension to perl's native regexp function. It binds anonymous hashes or named variables to matched buffers. Both normal regexp syntax and embedded regexp syntax are supported. You can view it as a tiny and petite data extraction system.

Regexp-Grammars adds grammatical parsing features to Perl 5.10 regexes.

The Perl::PrereqScanner scanner will extract loosely your distribution prerequisites from your files.

Shell-like regular expressions.

This is a second go at a module to simplify installing die() and warn() handlers, and to make such handlers easier to write and control. For most people, this just means that if use Religion; then you'll get noticeably better error reporting from warn() and die(). This is especially useful if you are using eval(). Religion provides four classes, WarnHandler, DieHandler, WarnPreHandler, and DiePreHandler, that when you construct them return closures that can be stored in variables that in turn get invoked by $SIG{__DIE__} and $SIG{__WARN__}. Note that if Religion is in use, you should not modify $SIG{__DIE__} or $SIG{__WARN__}, unless you are careful about invoking chaining to the old handler. Religion also provides a TraceBack function, which is used by a DieHandler after you die() to give a better handle on the current scope of your situation, and provide information about where you were, which might influence where you want to go next, either returning back to where
