Rools-04. has been released

cappela...@gmail.com (cappelaere) — Mon, 05 Nov 2007 16:20:44 UT

Minor release but great idea from Grant Mcinnes with ranges.
They can now be defined as facts as used in rules.
Let me know how this works out.
Still working on cleaning up the site...
Sorry it took so long for a new revision.

Re: facts must be an array

I was looking at this method Pat (from facts.rb):
def value
if @fact_value.size == 1
@fact_value[0]
else
@fact_value
end
end
along with this comment:
In my case I want to pass in a Range object, but since Range doesn't
have a size method it chokes here. I can get round this by adding a

What makes you think that?

facts must be an array

grant.mcin...@eyesopen.ca (Grant McInnes) — Mon, 20 Aug 2007 15:09:34 UT

Am I right in thinking that facts must be an array, rather than an
arbitrary type of object?

thanks, pat, for the fix...
moved my anonymous Person class to app\models and everything is ok
should have had it there in the first place as i will eventually have
a persons table in my database
learned something new, today, about classes and ruby and rails
Rools does rule!

any .csv file i try to read in a controller class generates the same
error, for instance:
rules = Rools::RuleSet.new '/rails/purl/businessrules/sal utations.csv'
generates the error:
rule_0

this is the working code i used as a basis for my rails app:
require 'test/unit'
require 'rools'
require 'rools/base'
require 'logger'
class Person
attr_accessor :name, :personicx
def initialize(name, personicx)
@name = name

Doug,
Can you duplicate the problem in a non rails example?
Would save me some time...
Pat.

Grant,
Great job about rspec!
I think we need to break this list of questions down a bit to avoid too much
confusion and lengthy responses...
Your defined rule is ready to trigger every time a "Patient" fact is
asserted. The convention is to use the lowercase name as a variable in the
condition. This is being enforced now to support multiple triggers.

Hi Pat:
I have lots of questions. I think probably most of what's going on
here is that I don't understand how rules engines work - this is my
first attempt. I have no context from other systems. If we can work
on this, I can write things up from a newb perspective, and hopefully
this can help someone else.

Re: [rools-dev] Can't get 0.3 to work

Hi Grant,
Would love to help but you might need to give me more details here.
bug #11965 is due to a typo. The error has been cleaned in 0.3 (still get
an error though).
You may want to try to give me a test case and full output in debug mode.
V/R,
Pat.

Can't get 0.3 to work

grant.mcin...@eyesopen.ca (gmcinnes) — Tue, 24 Jul 2007 20:43:03 UT

Hi Pat:
Great package with lots of potential, but I can't get 0.3 to work
properly. I'm having the same issues as described in bug #11965
I tried going back to 0.1.5 with require_gem 'rools', '=0.1.5' and
things seem to work properly there, but some of the nice functionality
like extends is missing, so it's not as useful to me.

Autotest

cappela...@gmail.com (cappelaere) — Sat, 21 Jul 2007 15:36:59 UT

Rools now supports Autotest in svn.
gem install ZenTest
Renamed specs to spec
Fixed Rakefile
install Growl/growlnotify
run rake spec:autotest in terminal window and specs get run when
source file is changed. You get notification on desktop via Growl (on
the Mac)...
Pretty cool.
Thanks Linda!
