elseif needs to be single word tag/keyword and expression shouldn’t have parenthesis same as if expression. http://twig.sensiolabs.org/doc/tags/if.html <body {% if page|default(‘login’) == ‘login’ %} class=”login” {% elseif page == ‘other’ %} class=”login” {% else %} class=”noclass” {% endif %}> </body>
Simply: SELECT NULLIF(regexp_replace(po_number, ‘\D’,”,’g’), ”)::numeric AS result FROM tbl; \D being the class shorthand for “not a digit”. And you need the 4th parameter ‘g’ (for “globally”) to replace all occurrences. Details in the manual. For a known, limited set of characters to replace, plain string manipulation functions like replace() or translate() are substantially cheaper. … Read more
Type traits: #include <iostream> #include <type_traits> // C++0x //#include <tr1/type_traits> // C++03, use std::tr1 template<typename T> void printType(T param) { if(std::is_same<T,char*>::value) std::cout << “char*” << endl; else if(std::is_same<T,int>::value) std::cout << “int” << endl; else std::cout << “???” << endl; } Or even better yet, just overload the function: template<class T> void printType(T partam){ std::cout << … Read more
I think both the fastest and most concise way to do this is to use NumPy’s built-in Fancy indexing. If you have an ndarray named arr, you can replace all elements >255 with a value x as follows: arr[arr > 255] = x I ran this on my machine with a 500 x 500 random … Read more
Assuming you want what you asked for, as opposed to suggestions for redesigning your code, you should look at Awaitility. For example, if you want to see if a file will be created within the next 10 seconds, you do something like: await().atMost(10, SECONDS).until(() -> myFile.exists()); It’s mainly aimed at testing, but does the specific … Read more
Ruby also has between?: if value.between?(lower, higher)
Another possibility is to use the operator iif in a SwitchMap. https://www.learnrxjs.io/learn-rxjs/operators/conditional/iif https://rxjs-dev.firebaseapp.com/api/index/function/iif but it can restrain the possibility to control specfic conditions on your Observable : myObservable1 .pipe( switchMap(result1 => iif(() => condition , myObservable2 , myObservable1 ) ) .subscribe(result => console.log(result)); Where you can replace ‘condition’ by a function returning a boolean. With … Read more
One way would be to convert the Boolean values to an integer, add the results, and compare to 1.
