php-mode

Mature, well-established codebase

The first lines of source code were added to php-mode in 2003. Projects with recent activity, and a code base more than five years old are likely solving vital problems and delivering consistent value, and may be organized to reward sustained effort by an engaged team of contributors.

Such a lengthy source control history in conjunction with recent activity may indicate that this code base and community are important enough to attract long-term commitment, and may also indicate a mature and relatively bug-free code base.

Note: The source code for php-mode might actually be older than the source control history can reveal. Many new projects begin by incorporating a large amount of source code from existing, older projects. You might be able to tell whether this is the case by looking for a rapid rise in the amount of code early in the project's history.

Very well-commented source code

php-mode is written mostly in Emacs Lisp.

Across all Emacs Lisp projects on Ohloh, 16% of all source code lines are comments. For php-mode, this figure is 59%.

This very impressive number of comments puts php-mode among the top 10% of all Emacs Lisp projects on Ohloh.

A high number of comments might indicate that the code is well-documented and organized, and could be a sign of a helpful and disciplined development team.

No recent development activity

The source code for php-mode has not been changed in over a year.

Over 75% of all projects on Ohloh have no recent activity. Open source has a "long tail" of projects whose developers have moved on. But the code is still there for all to benefit from!  

For this measurement, Ohloh considers only recent changes to the code. Over the entire history of the project, 2 developers have contributed.
