kandi X-RAY | toadstool Summary
toadstool is a style guide framework. concepts are simple, build in the abstract and apply to the semantic. ##run the app toadstool is a sinatra rack app. simply clone the app into a new directory, bundle install and then rake server. to simulate "production" mode run rake server production. this task will compile your sass with the compressed output style and closely simulates heroku's environment. we use this mode to perform final qa prior to deployment to heroku. ##sass / compass processing your sass to css can happen a few ways. by default, toadstool is set up to compile sass once via the following rakefile command. this is the most efficient way to do it and ensures that a static version of sass is made available in production. this task automatically invokes when you run rake server; there should be no need to run it manually. ###toadstool and sass toadstool style guide framework makes heavy use of sass as it's primary styling language read more ... ###developing sass be sure to run compass watch process in the background. this really is the best way to process edited sass. in the terminal it will be easy to see the sass error log if there are

QUESTION
This may be specific to the SWI Prolog module system.
Suppose we have three Prolog modules (in the SWI-Prolog module system):
robin
(in filerobin.pl
)arthur
(in filearthur.pl
)helper
(in filehelper.pl
).
Predicates robin:robin/0
(i.e. predicate robin_hood/0
in module robin
) and predicate arthur:arthur/0
call predicate helper:helper/2
(which is exported by module helper
).
Predicate helper:helper/2
then should call a predicate toolshed/1
, which is different depending on the caller modules. I would like helper/2
to call the toolshed/1
predicate associated with the predicate that calls helper/2
.
In Java, one would pass an interface with a toolshed()
method to helper()
, so that helper()
can call the interface and end up at the correct implementation.
How do I do it in Prolog?
Example code:
robin.pl
...ANSWER
Answered 2021-Feb-11 at 08:39Looks like I stumbled upon a solution:
The new helper.pl
It has a modified helper/2
: now helper/3
which accepts the module name of the caller as third argument and uses it to qualify the call to toolshed/1
:
(is it possible to find out by which module one is currently being called? without creating a stack trace?)

I'm using the Online Retail dataset from the UCI Machine Learning Repository in pandas, and I'm setting a multi-index consisting in CustomerID
as first level, and InvoiceNo
as second level. Here's the code:

QUESTION
I have two basic classes:
This is my english interpretation of the code: The Entree class is supposed to take in a name, and then some ingredients (it makes an array out of those), and then there is this hasIngredient function that lets me check if the array has certain elements...
Then there is the PricedEntree class which extends Entree. It inherits a construct, but then also takes the array and uses the "as" and puts it into "ingredient", and cycles through it (via foreach).
I want to use the PricedEntree class, because I want access to the getCost method; but I cannot seem to be able to make a valid instantiation of PricedEntree. I am getting an error saying:
...ANSWER
Answered 2019-Feb-13 at 00:26Your PricedEntree
class checks to see if the array of ingredients is an array of Entree
objects, you're sending it an array of strings. This line of code doesn't seem to make any sense:
