kandi X-RAY | regent Summary
Regent lets you query a data structure by asking true or false questions. Regent logic is written as single responsibility rules that are self-documenting, composable, and human readable. Let's look at an example. Taking the previous example a bit further, we can refine the scenario to be more precise. We can create and combine multiple rules to test this condition. If it is raining and the wind isn't so strong the umbrella will turn inside-out and blow out of our hands, we need an umbrella. Regent also provides a simple way to find or filter array items based on a regent rule.

QUESTION
I am working through a payment integration transformation. One xml payment fie can contain more than one payment. because of this there will be more than one instances of IBAN (). I need my XSLT to remove all spaces and hyphens from the one or many instances of . XML below. I have exhausted all options. as for this project this is the only art I need answers on. In the XML sample below there are two instances of IBAN. I have tried for-each, storing and removing characters in variable (ends up concat values in both elements)... any help would be great. This is sample data and not actual payment data.

QUESTION
First excuse my language and poor understanding of coding (I'm doing this by trial and error).
I have 2 dropdown menus that have a default option of "choose county" and Choose holiday park". When on these options I want the save button to be disabled. This works until I swap back and forth between the dropdown boxes.
Also, as an aside how do I have an explanation for the end user to complete the field before the button becomes active? I have a jsfiddle that demonstrates the issue. https://jsfiddle.net/cosypaws/gry0w98t/8/

Answered 2020-Jun-09 at 16:28Just set the "next" button to disabled when the first dropdown is changed:
QUESTION
I am trying to search for the strings in the brackets using the re.search method. From my examples of x, I am only able to properly find 'Parkwoods', I am not able to find any of the other strings.
This is what I have been doing initially, adding in \s for whitespaces etc., but I am still unable to find Garden District, Ryerson and Regent Park / Harbourfront
...ANSWER
Answered 2020-Mar-22 at 03:23Try the following regex:
\((\w|,| |\/)+\)
In terms of code: re.search(r"\((\w|,| |\/)+\)", x)
Explanation:
( and ) : match the outermost parentheses
( )+ :one or more of whatever's within the ( ), used to indicate "or"
\w|,| |/ : match alpha-numeric OR comma "," OR " " (space" OR "/" (backslash, which we escape like "/")
Try playing around on: https://regexr.com/
Edit: other comments build on the negated set [^)], but this would match ANY character not a right parens. You might want to impose stricter rules based on your application. For instance, it'd match (&&&*$$)
in Downtown Toronto(&&&*$$)
, which is something you may or may not want.
QUESTION
I have been asked to build a query that runs quality checks for data on a certain state test.
I have the following query that creates a variable named 'Flag' to identify cases where there are issues. The main query is really in a subquery, and I filter out all records where there isn't a flag by only selecting cases where Flag has a value.
I would like to be able to have a CASE WHEN for instances where there are duplicate tests. We do have some duplicates where, for the same student ID (test.studentID, studenttestscore.studentID, students.ID), a student will have the same test date for the same exam.
Test date, as you can see, is STUDENTTEST.TEST_DATE. Exams can be identified by either STUDENTTEST.ID or TEST.NAME. It might be easier to look for records where STUDENTTEST.test_date and STUDENTTEST.ID are the same for a STUDENTTEST.studentID. But once you get that count, it would have to be appended to the subquery here so that we can have a student name associated with it.

QUESTION
I'm trying to do a chloropeth map following this guide: https://www.r-graph-gallery.com/327-chloropleth-map-from-geojson-with-ggplot2.html
I mixed a bit of the tutorial with this answer(Chloropleth map with geojson and ggplot2), since I wasn't getting the result I expected. The cities were being filled with the same color, and it seemed as R wasn't understanding the data as numeric, and filled every city that had at least 1 user with the default color. (tried using as.numeric, didnt work either)
I downloaded "users by city" data from my website from Google Analytics using
...ANSWER
Answered 2020-Jan-28 at 22:09It looks like you have a couple relatively large values, while most are small. This causes 'skewing' of your color scale in a way that looks less interesting. Instead of graphing number of users, consider mapping based on a quantile .
Here is an implementation of grouping into quantiles using cut2()
from Hmisc
. In this case, values are cut into 5 groups.

QUESTION
I am trying to put different lights in a scene and have them cast shadows simultaneously. The problem is that every time I create a new osgShadow::ShadowMap for a light, the previous light stops casting shadow. I suspect that this has something to do with index or something, the same way every light has to have a setLightNum(x) defined. Below is the code used as reference for this image: .
...ANSWER
Answered 2019-May-24 at 16:56You are using a wrong method for this. To allow use multiple lights use:
osgShadow::ViewDependentShadowMap* sm0 = new osgShadow::ViewDependentShadowMap;
