I need help understanding what the generate and test method in prolog is, what it is used for and how to use it. I've searched for answers online but can't really find an answer to my question.

I'd like to know what suggestions there are for Googling (or using other search engines if preferable) for Ruby syntax. I'm very new, and a substantial part of my baptism by fire comes by way of reading other people's code. Ruby in particular can be challenging this way-- it's fantastically compact and easy to read if you know how to read it, so to speak. But figuring that out can be difficult at times. It's worth it, but difficult. So, for example, let's say I encounter an expression like this:
tquery = "#{MASTER_URL}#{query_str}"
Well, apparently there's something going on with the syntax #{stuff}, but what? A variable being manipulated, it seems? If you encountered such an expression and didn't know about interpolation/substitution and have no ready access to someone to ask directly, how would you go about Googling that? That's just an example, of course, but I hope it illustrates the type of problem I'd like to address.
Also, if there are better tags to apply to this post please let me know and I will add. Thank you.
Symbolhound is pretty good for this. For example, here's the search for Ruby's #{}.
Mind, as you can see from the results, it doesn't necessarily come immediately back and tell you what the notation you searched for is named, or how it's defined, but it does return some helpful results to get you started. It's especially useful for punctuation-based syntax elements that are difficult or impossible to search for in other search engines.
I am doing a specialization in rails .Its assignment is related to find maximum frequency words.I solve it all but it cant pass one test out of 19.Anybody doing that?
I have finished the assignment with no errors, you may just have a typo in your answer. If you post your code it would be easier to help you. A sample solution has been posted on GitHub Max-word-frequency.
This might be/seem like a basic question. Company just moved us to BO and trying to figure out a formula that would be easy in any other language. Can't seem to get the syntax and can't find documentation online.
=If([Disposition]=2 **Or 5**;Count([Sessionid]))
Apparently the "Or 5" part of this formula is wrong, cannot figure out how to implement it.
You need to list each condition separately. If you update it like below you should have it corrected.
=If([Disposition]=2 Or [Disposition]=5;Count([Sessionid]))
I am learning how to use the version of fuzzyCLIPS from NRC. I would
appreciate if someone could point out some ftp/web sites with examples and
code using fuzzyCLIPS. I find the manual difficult to learn from
Try a search for FuzzyJess. As the syntax for CLIPS and Jess are similar you might find some FuzzyJess examples that can be adapted to FuzzyCLIPS.
I want to write a ruby wrapper swi-prolog. Can anyone please tell me how to proceed with writing one?
I would appreciate if anyone please explain me what steps need to be considered while attempting to write this sort.
You can look at this post by Mauricio Fernandez:

When you are done with that, there's a follow-up article with ideas on how to make things more Rubyish by Jamis Buck:

Edit:
I also found PySwip which is a GPL Python - SWI-Prolog bridge. Even though it's not Ruby, it probably gives you some good ideas about how to tackle the problem.
