Determining whether the running ruby is outdated?

From: Lars Olsson on 10 Aug 2010 05:22 Hi, I'm writing a small utility that shows information on the currently running ruby environment. One part of the utility checks whether any gems is outdated, but I also want to check if the ruby interpreter itself is outdated. Getting the currently installed version is simple, but getting a list of released ruby versions seems a bit trickier. I'm mainly interested in *stable* source versions, but I don't mind if my utility lists development and rc versions as well. Does anyone know a good way of checking this? My first try was to use the ruby github mirror to fetch available tags. Then I tried using svn.ruby-lang.org to get the same information, but neither of those gave me the information I wanted in a simple way. Any suggestions on how to solve this? /lasso

Possibly parse this list: http://ftp.ruby-lang.org/pub/ruby/1.9/ et al. -r -- Posted via http://www.ruby-forum.com/.

I just went thru ALL the 1.8.x i386-mswin32 releases compiling a list, and did 1.9.1 also. I did NOT do any previews, or release candidates, or 1.9.0 or 1.6.x > > Any suggestions on how to solve this? I had to spend 2 days downloading every package, extracting the interpreter DLLs, a PITB. The file is not done.. I'm missing a few dates. I may also be missing a few patch_levels that were released for test, but no precompiled package was released. (not likely anyone is running them.) I wrote a PureRuby Backport Patch for older versions, that adds newer constants to older versions (<1.8.7), which you might like to use (you'll get the idea when you read it; it can be condensed into smaller code.) It's attached here, and in the post you'll see other links where it's available (rubyforge snippet library, etc.) http://redmine.ruby-lang.org/issues/show/3665 .. some has suggested I add RUBY_ENGINE to all before 1.9.x (but I haven't got to it yet.)

Here's the snippet for RUBY_ENGINE: # # RUBY_ENGINE was added sometime in the 1.9.x branch # if defined?(RUBY_ENGINE).nil? RUBY_ENGINE = RUBY_VERSION.split('.')[0..1].join('.') end -- Posted via http://www.ruby-forum.com/.

Thanks guys! I was hoping there was a simpler method than parsing directory listings (say, like a text file) but if that's the way to go then I'll just have to dig in. /lasso |
