The Perl virtual machine is a stack-based process virtual machine implemented as an opcodes interpreter which runs previously compiled programs written in the Perl language. The opcodes interpreter is a part of the Perl interpreter, which also contains a compiler (lexer, parser and optimizer) in one executable file, commonly /usr/bin/perl on various Unix-like systems or perl.exe on Microsoft ...
Common Lisp has numerous standard dynamic variables, and so threads cannot be sensibly added to an implementation of the language without these variables having thread-local semantics in dynamic binding. For instance the standard variable *print-base* determines the default radix in which integers are printed. If this variable is overridden ...
Windows installation scripts to allow Strawberry Perl to be easily uninstalled. Various non-standard but widely used Perl modules. These mostly relate to ease of installation of further extensions from the CPAN , but also include various tools that enhance the ability to install packages from other sources such as the Perl Archive Toolkit , the ...
Perl Archive Toolkit (PAR) is a cross-platform packaging and deployment tool for computer applications and libraries written in the Perl programming language. Its name is inspired by Java 's JAR (file format) technology.
POE, The Perl Object Environment can be thought of as a tiny modular operating system. One or more POE programs or instances can be run concurrently and are generally well suited for cooperative multitasking. The POE package consists of namespaces and abstractions that guide future development of POE in an open-ended CPAN-style convention.
The print function takes the result yielded by eval, and prints it out to the user. If it is a complex expression, it may be pretty-printed to make it easier to understand. The development environment then returns to the read state, creating a loop, which terminates when the program is closed.
RFC 3875 "The Common Gateway Interface (CGI)" partially defines CGI using C, [2] in saying that environment variables "are accessed by the C library routine getenv() or variable environ". The name CGI comes from the early days of the Web, where webmasters wanted to connect legacy information systems such as databases to their Web servers.
In these languages, including the line __DATA__ (Perl) or __END__ (Ruby, old Perl) marks the end of the code segment and the start of the data segment. Only the contents prior to this line are executed, and the contents of the source file after this line are available as a file object: PACKAGE::DATA in Perl (e.g., main::DATA) and DATA in Ruby ...
