  • Uses the fabulous Hpricot library to parse HTML from Ruby. Extracts all elements of "command' class and displays unescaped text from inside these elements. The following command can help install dependencies (apart from Ruby itself) gem sources -a http://gems.github.com && sudo gem install why-hpricot

  • This is the simple revision number on stdout, that can be fed to any useful/fun script of yours. Setting LC_ALL is useful if you use another locale, in which case "Revision" is translated and cannot be found. I use this with doxygen to insert my source files revisions into the doc. An example in Doxyfile: FILE_VERSION_FILTER = "function svn_filter { LC_ALL=C svn info $1 | grep Revision | awk '{print $2}'; }; svn_filter" Share your ideas about what to do with the revision number !

    -2
    LC_ALL=C svn info | grep Revision | awk '{print $2}'
