QUESTION
I have a table having a column as below. "Top: xx,xx" part is the price of a product and I want to change the comma to dot. Like Top:26,70
should be Top:26.70
Since there might be multiple occasions within the same row and there is no pattern for the rows I could not split the string.

QUESTION
As noted in another StackOverflow answer that I can't seem to find anymore, this pattern emerges frequently in practical Prolog code:
...ANSWER
Answered 2018-Oct-31 at 17:06The usually named soft-cut control construct is available in several Prolog systems. CxProlog, ECLiPSe, JIProlog, SWI-Prolog, and YAP provide it as both a *->/2
predicate and infix operator. Ciao Prolog, SICStus Prolog, and YAP provide an if/3
predicate with the same semantics.
My main use of this soft-cut control construct is in the implementation of coinduction in Logtalk, where it plays a critical role. Outside of this case, I rarely use it.
The ->/2
, on the other hand, it's widely used. The implicit cut in the if part is local to the construct and its usage avoids, as in your example, trying to prove the guard twice, which can be computationally expensive. It may not be pure but, as with the cut, as long as you're fully aware of its pros and cons, it's a useful control construct.
P.S. Logtalk provides unit tests for this control construct for the *->/2
variant at https://github.com/LogtalkDotOrg/logtalk3/tree/master/tests/prolog/control/soft_cut_2_3 and for the if/3
variant at https://github.com/LogtalkDotOrg/logtalk3/tree/master/tests/prolog/control/if_3

I have a Card with parameters (Color, Value) and method to output Card's parameters.
Error binary '<<' : no operator found which takes a right-hand operand of type 'CardColor' and 'CardValue'(or there is no acceptable conversion)
Card.h
...ANSWER
Answered 2017-Nov-09 at 16:09From you comment:
binary '<<' : no operator found which takes a right-hand operand of type 'CardColor' and 'CardValue' (or there is no acceptable conversion)
You also need to provide operator<<
for the Color and Value class.
example of this for the Color class:
QUESTION
I am trying to calculate the revenue of each instructor from neo4j graph database with the following query
...ANSWER
Answered 2017-Mar-04 at 12:44Since you added relationship between your nodes, the query can be greatly simplified.
We need paths from each instructor to child instructors up to 3 levels down, and depending on how far down, we can get the appropriate percentage to run the calculations on the given transactions, then sum it all up.
Here's an example query that should work, though it will report on any instructor with at least one child instructor, instead of only instructors with at least 3 levels down of child instructors.

Install kral
Install kral pip install -e git+https://github.com/Tawlk/kral/#egg=kral
Configuration After installation simply run the kral cli command which will copy a configuration file to: ~/.kral/config.py This file is a basic key-value mapping of the configuration options available. You will want to set your credentials and other service specific settings here. Note: The user configuration settings need to be set in order for kral streaming to work from the CLI; however you may also set the configuration options at runtime within your application by doing: from kral import config and setting the values according to the config.py template. (i.e config.TWITTER = {'user': 'cute', 'password': 'kitty'})
Collect data From here you can start using the kral.stream() generator to collect data within your appliction. Example that outputs the latest social data on "android" and "bitcoin" across all available networks. import kral for item in kral.stream(['android','bitcoin']): print "%s | %s" % (item.service,item.text) Example that outputs the latest social data on "obama" using only twitter. import kral for item in kral.stream('obama','twitter'): print "%s | %s" % (item.service,item.text) You can also collect data via the CLI interface. kral stream --services="twitter,facebook" --queries="android" For more information on the CLI interface run: kral --help
