README for openhub-repositories.git

openhub.net (formerly ohloh.net) has an interesting comparison of the number of public repositories on the net, based on searches of popular hosting services. This comparison is available at <https://www.openhub.net/repositories/compare> and shows an estimated market share between Bazaar, CVS, Git, Mercurial and Subversion.

I've been monitoring this since 2014-08-05 to see how things were developing, and it's a good indication of the popularity of the various version control systems. Generated SVG graphs are stored in graph/:

• relative.svg
  Show graphs of relative growth between the various version control systems.
• relative-zoom.svg
  Same as relative.svg, but since the Git graph dwarfs all the others, this is a zoomed-in version to show the differences between Bazaar, CVS, Mercurial and Subversion better.
• repos.svg
  Graph of total number of repositories.

A status report generated from the newest data is stored in status.txt.

Usage

• make update
  Update repos.dat with new data from openhub.net.
• make
  Create repos.sql, repos.sqlite and README.html, update and view status.txt.
• make plot
  Generate relative Gnuplot graph.
• make bezier
  Same as make plot, but use Bézier smoothing.
• make zoom
  Generate zoomed-in relative Gnuplot graph to show the differences between Bazaar, CVS, Mercurial and Subversion.
• make abs
  Generate absolute plot. Not as detailed as the relative plot.
• make status
  Create some tables with statistics.
• make repos.sqlite
  Create the SQLite database.
• make repos.sql
  Create repos.sql.
• make svg
  Create SVG plots in graph/.
• make README.html
  Create README.html from README.md.
• make dups
  If there are no updates, execute this to store the new entry in dups.dat. This is to avoid polluting repos.dat with duplicates, and also document that new data was fetched, but there were no changes.
• make sort
  Sort repos.dat and dups.dat. Used by make dups.

Dependencies

These programs are necessary to run the various make commands or ./get-new-stats.py:

• sqlite3
• gnuplot
• Python v3
• /bin/sh, found on most *nix variants
• Perl
• cmark, CommonMark parser to generate README.html
