    With the freeze of Ruby 1.9.3 coming up near the end of the month I =
    looked at how much documentation coverage ruby has for it's standard =

    Files: 511

    Classes: 1036 ( 624 undocumented)
    Modules: 228 ( 136 undocumented)
    Constants: 1335 (1134 undocumented)
    Attributes: 738 ( 381 undocumented)
    Methods: 8098 (2960 undocumented)

    Total: 11435 (5235 undocumented)
    54.22% documented

    Can we make it to 60% coverage? That's only another 1626 items to =

    I've written a blog post with further information including a link to an =
    hourly-updatidng coverage report and a tutorial by Steve Klabnik on how =
    to write documentation and get it committed, the short link is here:

    Let's make Ruby 1.9.3 the best-documented release ever!=

    Thanks! I never really contributed to Ruby, but if it's that easy I'll
    probably do so.

    this is certainly a worthwhile effort - thanks for organizing it...
    happy to help out in any way i can.

    I'm not sure who makes these decisions for, but is there any chance that we could get Yardoc-formatted documentation (or at least a fresh stylesheet for standard rdoc output) this time around?

    I'd be very inclined to help out with this effort if I knew the output was going to look fresh and appealing.

    (Yes, I know I could host my own styled version of the docs. But I'm talking about what comes up first on Google.)

  7. I would appreciate this more for the fact that the syntax is better.

    That too, but I figured if the goal here was to complete the documentation (instead of revamping it), a complete conversion to Yardoc would be a hard sell. (If that's not the case, I'll be thrilled.)

  10. Hi,

    based in your coverage @ I took a
    few looks, e.g. it says:

    # in files:
    # ext/socket/raddrinfo.c
    # ext/socket/lib/socket.rb

    class Addrinfo

    I took a look at ext/socket/raddrinfo.c and found addrinfo_initialize()
    with lots of documentation above it which I also see reflected at .

    Next sample was

    class CSV # is documented

    # in file lib/csv.rb
    def raw_encoding(default = Encoding::ASCII_8BIT); end


    taking a closer look, it's method marked private.

    I've a few questions now:

    - for Addrinfo, is there really still something missing or does this
    come from the additional ruby code in ext/socket/lib/socket.rb and the
    coverage report just can't connect both of these together?

    - Is there an encouragement to document private methods? If not it would
    be nice if they could be omitted from the coverage. Otherwise just so we
    know what the goal is.

    - While I was looking at addrinfo_initialize() in ext/socket/raddrinfo.c
    and then looked at , I
    noticed that at the HTML page there is a typo, it says "The instnace
    contains..." but the docs in the code are right. Looking with git blame
    at the code docs it said last change was in 2009-11-04 12:02:37 . That's
    now more than two years and I'm wondering if looking at will give generally a wrong impression
    because the docs aren't up to date? Is there some automatic generation?

    thanks for clearing things up,

  11. I can't speak for Eric, but I think part of documenting is marking the
    code which does not need documenting with :nodoc:

    Ever since 1.9 came out, I've felt like has fallen behind. has been my go-to site for documentation:

    Justin Collins, Jun 16, 2011
  12. But rdoc, at least by default, does not document private methods. I
    assume it's just a limitation of the coverage tool for now.
    Thanks, I quickly noticed it contains stdlib but not core.

    I'm still looking for a convenient way to quickly search through the
    current docs. Currently I use a FF4 keyworded search which uses the
    integrated search on :

    The results I get back when I search for e.g. split or other methods are
    often nearly perfect. That's where I also found Addrinfo.

    The advantage at ruby-doc, at least for me, is that it includes core;
    and I need core too.

  13. It does, actually. It's a bit hidden under "stdlib" => "core". :)

    There is no class documentation for Addrinfo. Either a Document-class: =
    Addrinfo needs to be added to the C file or a class comment needs to be =
    added to the ruby file.
    Yes, but if the maintainer of the library decides that a private method =
    is also an implementation detail it may be hidden by :nodoc:

    Private methods can be API. For example, when you subclass you may need =
    to call a private method for proper operation.

    I'm not sure how ofter updates, I don't maintain it.=

    When you run `make` on ruby trunk rdoc is run with --all so private =
    methods are picked up. The coverage report does the same.=
