Popular programming languages

One question was always of my interest right since I started working as a Open Source Data Analyst at SAP Labs, Palo Alto: Which is the most popular/used language in the Open Source development? Thus, I decided to do an analysis of number of projects where a particular language is used. The list below shows the top ten entries.

Language

Percentage

Java

18.6

C++

17.3

C

16.0

PHP

13.2

Perl

6.1

Python

5.0

C#

3.8

JavaScript

3.5

Visual Basic

2.1

Delphi/Kylix

2.0

Unix Shell

1.9

Assembly

1.5

PL/SQL

1.1

Others

7.8

Then I thought that this metric is not a fair metric for evaluation. First reason is that the projects are not of the same size in terms of Lines of Code and secondly there are is large variation among the number of developers for an open source project. Then I rank ordered the languages by the total number of lines of code for a particular language. The results are as follows.

Name

Ratio

C/C++

47.29%

Java

26.90%

PHP

7.63%

C#

5.17%

JavaScript

3.44%

Python

3.00%

Perl

2.22%

Pascal

1.15%

Ruby

0.93%

shell script

0.75%

Tcl

0.75%

Objective C

0.51%

Emacs Lisp

0.17%

Erlang

0.07%

Scheme

0.02%


Here we can see that C/C++ has much more impact than Java. This can be contributed to large projects in C/C++ like Linux where there is a lot of effort involved. On the other hand even though Java has larger number of projects they are smaller in size and effort.
