Hi, I have a custom matcher that I call XMLDiff that takes an actual
XML string and an expected one and uses RSpec’s normal line differ to
show the difference at the node level. It uses a method called
be_functionaly_eql, because two XML strings can be the same regardless
of whitespece. I.e. they are functionaly equivalent. If you ran both
through the same parser, they would (should) result in the same
behavior. So:
actual_xml.should be_functionally_eql(“<xmlstring … >”)
If they are not, you get a context diff right to the element level.
Useful for finding errors in long XML strings.
I have searched for such a thing to no avail. There may be other
solutions and I;d be interested in seeing them. But this is what I
came up with.
The question is, how would you recommend sharing it? I am new to
gem-ing, but can it be packaheged that way, or is there some other
method for sharing custom matchers? I can host it on Github, if that
is a recommended way to do so.
Thanks
Ed

For most users, gems are the easiest answer. By all means, host source
on
github if you want people to contribute, or have a place to inspect
code,
but you don’t need a public source repository in order to push gems to
gemcutter.

HTH,
Yes it does. That was my plan, to add a gem to my github account. I’ll
search out other DSLs for RSpec and see how they packaged them as a
gem. I imagine the easiest way to use it is to add the require to
spec_helper.rb (assuming you have one) and then call the
be_functionally_eql in your specs as normal.
Thanks,
And Happy New Year!

A standard location for RSpec matchers would be pretty handy though, WDYT?
First, I have no cycles to start setting something up like this for a
while
now. I’m trying to wrap up the loose ends on the book and get it to
production. After that, any spare time I have is going to be devoted to
getting the rspec-2.0 and rspec-rails-2.0 (for rails-3.0) projects
rolling
in earnest.
That said, I definitely think we need a home for information about
matchers.
Hosting them, however, is something I’d rather leave to the
professionals 
I’ve imagined a website where folks can list info about matcher
libraries
and others can comment and possibly vote on them. If anybody wants to
volunteer to drive this in the short run, that would be great, but I
won’t
be able to do it myself for several months.
Cheers,
David

Good luck on the book. I am eager to buy it!

Just a suggestion, several other projects have contributions listed on
their Git hub wiki. Can we create a page for them, linking to other
Github accounts. I don’t knoe about voting and such, but it might be a
start. The rspec.info page can just link to the Github wiki for a user
submitted contributions page and people can go from there. Thereby
offloading the responsibility.
If I can help help in any way, let me know.

I think he should. It is Christmas, and it’s not like David ever does
anything else for the community

I like! A wiki solves 90% of problems like this with 2% of the effort.
I hadn’t realised the wiki had moved along - unlike Cucumber, I still
see the static site as the primary reference.
