Dancer (software)
Dancer is an Open-source software, open source lightweight web application framework written in Perl and inspired by Ruby (programming language), Ruby's Sinatra (software), Sinatra. In April 2011, Dancer was rewritten from scratch and released as Dancer2. The reason for the rewrite was to fix architectural issues and eliminate the use of singleton pattern, singletons. Development of Dancer1 was at first frozen, but was later continued to maintain backward compatibility for existing apps. Dancer is developed through GitHub, with stable releases available via CPAN. Dancer2 is released as a separate module. Example #!/usr/bin/env perl use Dancer2; get '/hello/:name' => sub ; get '/redirectMeTo/:trgval' => sub ; start; Features Out-of-box Unlike other frameworks such as Catalyst (software), Catalyst, Dancer only requires a handful of CPAN modules and is very self-contained. Standalone development server Dancer includes a standalone development server that can be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perl
Perl is a family of two high-level, general-purpose, interpreted, dynamic programming languages. "Perl" refers to Perl 5, but from 2000 to 2019 it also referred to its redesigned "sister language", Perl 6, before the latter's name was officially changed to Raku in October 2019. Though Perl is not officially an acronym, there are various backronyms in use, including "Practical Extraction and Reporting Language". Perl was developed by Larry Wall in 1987 as a general-purpose Unix scripting language to make report processing easier. Since then, it has undergone many changes and revisions. Raku, which began as a redesign of Perl 5 in 2000, eventually evolved into a separate language. Both languages continue to be developed independently by different development teams and liberally borrow ideas from each other. The Perl languages borrow features from other programming languages including C, sh, AWK, and sed; They provide text processing facilities without the arbitrary data-le ...

UWSGI
uWSGI is an open source software application that "aims at developing a full stack for building hosting services". It is named after the Web Server Gateway Interface (WSGI), which was the first plugin supported by the project. uWSGI is maintained by Italian based software company unbit. uwsgi (all lowercase) is the native binary protocol that uWSGI uses to communicate with other servers. uWSGI is often used in conjunction with web servers such as Cherokee and Nginx, which offer direct support for uWSGI's native uwsgi protocol, to serve Python web applications such as Django. For example, data may flow like this: HTTP client ↔ Nginx ↔ uWSGI ↔ Python app. A common alternative to uWSGI is Gunicorn The Gunicorn "Green Unicorn" (pronounced jee-unicorn or gun-i-corn) is a Python Web Server Gateway Interface (WSGI) HTTP server. It is a pre-fork worker model, ported from Ruby's Unicorn project. The Gunicorn server is broadly compatible with .... References External link ...

Plack (software)
Plack is a Perl web application programming framework inspired by Rack for Ruby and WSGI for Python, and it is the project behind the PSGI specification used by other frameworks such as Catalyst and Dancer. Plack allows for testing of Perl web applications without a live web server. Plackup is a command line utility to run PSGI applications from the command line. PSGI PSGI or Perl Web Server Gateway Interface is an interface between web servers and web applications and frameworks written in the Perl programming language that allows writing portable applications that can be run as standalone servers or using CGI, FastCGI, mod_perl, et al. It is inspired by the Web Server Gateway Interface for Python, Rack for Ruby and JSGI for JavaScript. A PSGI application is a Perl subroutine that accepts arguments as a single hash reference and returns a reference to an array of three elements: an HTTP status code, a reference to an array of HTTP headers and a reference to an array of HTTP ...

Catalyst (software)
Catalyst is an open source web application framework written in Perl, that closely follows the model–view–controller (MVC) architecture, and supports a number of experimental web patterns. It is written using Moose, a modern object system for Perl. Its design is heavily inspired by frameworks such as Ruby on Rails, Maypole, and Spring. A web application developer would use Catalyst to deal with code common to all web applications: it provides interfaces to web servers and receiving page requests, dispatching these into developer-written code to process and return the requests, and provides a standardised interface for data models, authentication, session management and other common web application elements. All of these elements are implemented as plugins to a set of common interfaces, allowing the developer to change the specific method used (e.g. a session storing in shared memory versus as a database table, or using FastCGI versus operating as an within Apache's mod_perl) ...

CPAN
The Comprehensive Perl Archive Network (CPAN) is a repository of over 250,000 software modules and accompanying documentation for 39,000 distributions, written in the Perl programming language by over 12,000 contributors. ''CPAN'' can denote either the archive network or the Perl program that acts as an interface to the network and as an automated software installer (somewhat like a package manager). Most software on CPAN is free and open source software. History CPAN was conceived in 1993 and has been active online since October 1995. It is based on the CTAN model and began as a place to unify the structure of scattered Perl archives. Role Like many programming languages, Perl has mechanisms to use external libraries of code, making one file contain common routines used by several programs. Perl calls these ''modules''. Perl modules are typically installed in one of several directories whose paths are placed in the Perl interpreter when it is first compiled; on Unix-like ope ...

Backward Compatibility
Backward compatibility (sometimes known as backwards compatibility) is a property of an operating system, product, or technology that allows for interoperability with an older legacy system, or with input designed for such a system, especially in telecommunications and computing. Modifying a system in a way that does not allow backward compatibility is sometimes called " breaking" backward compatibility. A complementary concept is forward compatibility. A design that is forward-compatible usually has a roadmap for compatibility with future standards and products. A related term from programming jargon is hysterical reasons or hysterical raisins (near-homophones for "historical reasons"), as the purpose of some software features may be solely to support older hardware or software versions. Usage In hardware A simple example of both backward and forward compatibility is the introduction of FM radio in stereo. FM radio was initially mono, with only one audio channel represented ...

Cross-platform
In computing, cross-platform software (also called multi-platform software, platform-agnostic software, or platform-independent software) is computer software that is designed to work in several computing platforms. Some cross-platform software requires a separate build for each platform, but some can be directly run on any platform without special preparation, being written in an interpreted language or compiled to portable bytecode for which the interpreters or run-time packages are common or standard components of all supported platforms. For example, a cross-platform application may run on Microsoft Windows, Linux, and macOS. Cross-platform software may run on many platforms, or as few as two. Some frameworks for cross-platform development are Codename One, Kivy, Qt, Flutter, NativeScript, Xamarin, Phonegap, Ionic, and React Native. Platforms ''Platform'' can refer to the type of processor (CPU) or other hardware on which an operating system (OS) or application runs, t ...

Singleton Pattern
In software engineering, the singleton pattern is a software design pattern that restricts the instantiation of a class to a singular instance. One of the well-known "Gang of Four" design patterns, which describe how to solve recurring problems in object-oriented software, the pattern is useful when exactly one object is needed to coordinate actions across a system. More specifically, the singleton pattern allows objects to: * Ensure they only have one instance * Provide easy access to that instance * Control their instantiation (for example, hiding the constructors of a class) The term comes from the mathematical concept of a singleton. Common uses Singletons are often preferred to global variables because they do not pollute the global namespace (or their containing namespace). Additionally, they permit lazy allocation and initialization, whereas global variables in many languages will always consume resources. The singleton pattern can also be used as a basis for oth ...
