The Transparent Language Popularity Index

The tool

The Language Popularity Index tool is a fully automatic, transparent, open-source and free tool to measure the popularity of programming languages on the Internet.

The measurement of programming language popularity suffers two common problems that are probably the same for most market studies:

1. The study depends on arbitrary choices on what to measure: blogs, book sales, wikis, open-source projects, jobs or videos ? Or which mix of all that ?
2. The study may depend on cumbersome semi-manual methods with their own problems:
   • if the method is too complex, nobody will try to verify the results
   • mistakes may remain undetected
   • when a mistake becomes evident, one may either correct it but must admit and explain that the results were wrong for a long time, or postpone or smooth the correction.

The first problem has no real solution since it is a question of definition. However, a fully parametrizable measurement tool may help discussing the various aspects of that definition.
We have a solution to the second problem: the tool behind the Language Popularity Index is fully automatic.
Moreover, you can easily verify the results:

• all results, including intermediary ones, are published
• a detailed results grid let you verify individual queries just by clicking the results
• you can download and build the automatic tool and run it yourself.

Download

Download the Language Popularity Index tool from the SourceForge project page.

NB: you may also need to check the Subversion revisions to get the latest source changes and search engine configurations.

Notes on recent queries

• June 2013: Yahoo! doesn't display number of search results anymore - so it will eventually disappear completely from the index in a later edition...
• More in the history: "Changes" sheet in the search.xls file, or in the Subversion log (link above).

The results

1. The main result is the following ranking (NB: no more maintained):

2. But wait: since we are transparent, we also provide all necessary data to reproduce the above results in the following table. Note that you can click on each count of the cells (language, engine) to see yourself the results. Depending on your location, browser, language settings, cookies, etc. the engine may return a slightly different search count +/- a few percents. Note also that the time lag between now and the time at which the grid has been obtained (displayed on the top) is crucial: the search engine data are very dynamic, especially, of course, those with a one-year filtering.

Some explanations about the choices of categories "general-purpose", "script", "other". The choices are subjective and cannot be perfect due to some overlap of categories' definitions.

• The union of all categories, "Any", covers all queried languages. If you don't like the attempt of categorization at all, stick with the "any" results column and just ignore the other ones!
• "General-purpose" covers general-purpose languages, usually compiled or compilable. Variables don't exist before or after the program's execution. After compilation and linking, a standalone executable is available.
• "Script" covers mostly interpreted languages (optionally compiled), often with dynamic typing. They are often interactive or have an interactive mode, where commands or scripts can be run in random order. Variables are set on-the-fly, may change type, may not be declared, may exist before the program's execution. Some may exist after the program's execution and can be reused for the next execution, with different values. Mostly programs need a specific environment to be run.
• "Other" covers specialized languages, also called Domain-Specific Languages (DSL's). They are bound to a specific purpose like education, a database system, an accounting system, an administration software, a sound or graphics system, a document display, or a hardware description. Their use outside their dedicated purpose may be theoretically possible but perhaps difficult and definitely not appropriate.
