What are the top open source programming languages?

Basm allah alrhman alrahim

there are a lot of comparison at wikipedia about programing language .

all of theme are so important but you must dig if you want to chose one of theme

my recomendation are php for websites developer , java for all OS , C# for windows , c/C++ for linux , and windows , why did I choose those programming languages ? because they have a lot of librarys , a lot of librarys mean easier program making .

Python. 

Why??? ↓↓↓↓

Advantages/Benefits of Python

The diverse application of the Python language is a result of the combination of features which give this language an edge over others. Some of the benefits of programming in Python include:

1. Presence of Third Party Modules:

The Python Package Index (PyPI) contains numerous third-party modules that make Python capable of interacting with most of the other languages and platforms.

2. Extensive Support Libraries:

Python provides alarge standard library which includes areas like internet protocols, string operations, web services tools and operating system interfaces. Many high use programming tasks have already been scripted into the standard library which reduces length of code to be written significantly.

3. Open Source and Community Development:

 Python language is developed under an OSI-approved open source license, which makes it free to use and distribute, including for commercial purposes.

Further, its development is driven by the community which collaborates for its code through hosting conferences and mailing lists, and provides for its numerous modules.

4. Learning Ease and Support Available:

 Python offers excellent readability and uncluttered simple-to-learn syntax which helps beginners to utilize this programming language. The code style guidelines, PEP 8, provide a set of rules to facilitate the formatting of code. Additionally, the wide base of users and active developers has resulted in a rich internet resource bank to encourage development and the continued adoption of the language.

5. User-friendly Data Structures:

Python has built-in list and dictionary data structures which can be used to construct fast runtime data structures.  Further, Python also provides the option of dynamic high-level data typing which reduces the length of support code that is needed.

6. Productivity and Speed:

Python has clean object-oriented design, provides enhanced process control capabilities, and possesses strong integration and text processing capabilities and its own unit testing framework, all of which contribute to the increase in its speed and productivity. Python is considered a viable option for building complex multi-protocol network applications.

Python

Python can be described as a first programming language that is easy for people to pick up quickly. Developed in the 80’s by Guido van Rossum, he handed over the language to the non-profit Python Software Foundation. This foundation serves as the administrator of the language. The language is open source and is free to use even for commercial application. Usually used as a scripting language, programmers can easily produce large quantities of readable as well as functional code in a short period.

Features associated with Python:

• It is an interpreted and object-oriented programming language
• Similar to PERL, It has gained popularity because of its clear syntax as well as readability
• It is portable – thus it can be interpreted in a number of operating systems, including Unix based systems, various versions of Microsoft Windows 98, Mac OS, MS Dos and OS/2.
• The source code is open for modification and reuse
• Relatively easy learning curve
• Python has a very simple syntax and is an example of a FLOSS.
• It is a high level language that does not need compilation to binary
• It supports procedure-oriented programming as well as object-oriented programming Python has a very powerful but simplistic way of implementing OOP.
• It can be imbedded in C and C++.

Disadvantages

• Not the best for memory intensive tasks
• Interpreted language
• Slow compared to C/C++ or Java
• There is a lack of true multiprocessor support
• There have been issues of slower software performance
• A Lack of prepackaged solutions exists
• The programming language is relatively obscure
• There are Documentation gaps
• Lack of GUI as well as teamwork tools

Ruby

Ruby is a dynamic as well as open-source, object-oriented programming language. Developed by Yukihoro Matsumoto in the 90’s, it is one of the youngest languages, which is being still widely used. The syntax is easy to read and less complex than many other programming languages. The language is object oriented, but it is also capable of supporting various programming techniques such as procedural, functional, and imperative programming. Thus, it is very flexible in its approach as well.

Some of the features of ruby are:

• The free format allows writing of programs from any line or column
• The lowercase letters as well as uppercase letters are distinct
• The syntax/infrastructure makes using anonymous blocks easy
• provision of open classes
• The language Can seamlessly inherit from any of the standard classes
• Provides for clean object hierarchy that makes meta-programming easy
• Is capable of writing brief one-liners for system administration tasks

Some of the disadvantages of Ruby are:

• Smaller community and support
• Slower processing
• Lack of regular updates
• Higher learning curve

PHP

PHP is becoming the most popular open source programming language and has made itself to the no.1 position. According to many leading industry leaders, PHP has emerged as the most developer friendly open source language, which explains why various open source packages such as Joomla and Drupal are being built on PHP. Being budget friendly, PHP based solutions are being utilized by entrepreneurs and SME’s as well. Today, many developers are debuting on PHP, giving it a strong boost and strong community base.

Some features of PHP

• No need to specify data type for variable declaration – an example of a loosely typed language
• Provides cross platform compatibility
• Allows predefined variables called super-globals.
• Predefined error reporting constants are available
• Supports extended regular expressions
• Ability to generate dynamic page content
• Ability to collect form data and even send and receive cookies
• Allows creating, opening, reading, writing, deleting, and closing files on the server
• Output not limited to HTML, but also images, PDF files, flash, XHTML, and XML.
• Runs on various platforms such as windows, Linux, Unix, Mac OS x, etc.
• Compatible with almost all servers used presently (apache, IIS, etc)

Some of the disadvantages of PHP

• Language semantics can be changed by global configuration parameters – this can complicate deployment and portability.
• PHP lacks named parameters
• PHP is constantly changing – newer updates bring newer problems
• PHP has an ugly and unpredictable type system
• Less secure
• Less modular – hence not suitable for very large projects

Perl

According to the PERL website, PERL is a powerful, stable, mature, and portable language, which is highly capable and feature rich. It is veteran in its existence with over 27 years of development. Perl 5 runs on over 100 platforms, which range from portables to mainframes. PERL is suitable for rapid prototyping as well as large-scale development projects.

Further, PERL 5 is a part of the PERL family of languages, which also includes PERL 6. However, PERL 6 is a separate language that has its own development team, but its existence and development will have no significant impact on the development of PERL 5.

Thus, it comes as a dynamic and a dynamically typed, scripting (interpreted) language that is most comparable with PHP as well as python. It is ideally suited for processing and producing text data. It is highly portable, and widely supported. The syntax owes a lot to shell scripting tools that were popular in the past.

Some Features of PERL

• Simple syntax
• Easy to learn
• Can be easily understood by novices as well as expert programmers
• It is cross platform, hence programs written for one platform can run on different platforms with very little or no alteration.
• Perl is versatile and has a very comprehensive library of modules.
• Perl also has a very powerful as well as flexible object-oriented programming syntax
• It supports multiple platforms including Linux, Microsoft DOS, Windows, Apple Mac, and some mobile platforms as well.

Disadvantages of PERL

• Stagnation
• Overcome by Python and Java

Java

Java is one of the web world’s veteran and influential programming languages, which is mostly open source today. It is being used at the heart of many web and non-web applications on all platforms and operating systems, and many devices. It is a deeply featured as well as class based object oriented language. The special status that Java has gained over the years makes it a very valuable system. However, due to its portability and applicability, it can be very difficult to grasp, thus making it difficult to program effectively and efficiently.

Features of Java

• Easy to learn
• It is easy to write, compile, and debug compared to other programming languages
• It is object oriented
• Allows you to create modular programs and reusable code
• Ease of portability
• Platform independent both at the source as well as binary levels

Disadvantages of Java

• Interpreted language
• Time consuming – not speed intensive
• Lack of support for low-level programming
• Supports GUI control but has less features
• No garbage control features

ASP.NET

Microsoft has continued its commitment to open source. Now, it not only hosts projects at CodePlex Forge, but also supports many open source projects, and even creates their own open source projects. Today ASP.NET MVC, Web API and Web Pages (Razor) are open source projects. The source code ASP.NET MVC, Web API, and Web pages have been released under the Apache 2.0 license. Microsoft continues to fully support ASP.NET. The products are actively developed by the ASP.NET team that is assigned to the Microsoft Open Tech Hub in collaboration with an open source development committee.

Features

• Rich and robust server and client side controls
• Support for defining own controls.
• Fairly rapid deployment
• Built in security features
• Flexible and mature framework

Disadvantages

• Developers need to be familiar with HTML and CSS
• Non availability of drag and drop controls such as web forms
• Need to know client side code and HTML code
• Known vulnerabilities

I think most of programming languages are free, however the IDE of framework may be will not be free because its developed by a group of computer engineers.

Anyway, if you talk about the websites, PHP is most top open source programming language and if you talk about desktop C++ is the most top on.

This my opinion.

Tanks for invitation,,,

Python because it has largest free open source libraries

Python

Python can be described as a first programming language that is easy for people to pick up quickly. Developed in the 80’s by Guido van Rossum, he handed over the language to the non-profit Python Software Foundation. This foundation serves as the administrator of the language.
