According to the Racket documentation, there is no difference — there is only a convention to use [ and ] for cond clauses (and use your judgement for the rest, as far as I understand): The use of square brackets for cond clauses is a convention. In Racket, parentheses and square brackets are actually interchangeable, … Read more
No. Component styles are shared between all instances of a component, either because they’re statically extracted to a .css file, or because they’re injected into a single <style> element that all components reference. If it were possible to put variables directly inside the component’s <style>, it would mean that Svelte would need to create encapsulated … Read more
I don’t think it is possible. You can reuse “node” but not part of it. bill-to: &id001 given : Chris family : Dumars ship-to: *id001 This is perfectly valid YAML and fields given and family are reused in ship-to block. You can reuse a scalar node the same way but there’s no way you can … Read more
This is Flowtype’s Exact Object type syntax.
This is the inclusive range operator. The range x..=y contains all values >= x and <= y, i.e. “from x up to and including y”. This is in contrast to the non-inclusive range operator x..y, which doesn’t include y itself. fn main() { println!(“{:?}”, (10..20) .collect::<Vec<_>>()); println!(“{:?}”, (10..=20).collect::<Vec<_>>()); } // Output: // // [10, 11, … Read more
There is no symbol for line continuation in Kotlin. As its grammar allows spaces between almost all symbols, you can just break the statement: val text = “This ” + “is ” + “a ” + “long ” + “long ” + “line” However, if the first line of the statement is a valid statement, … Read more
The tail position is a position which an expression would return a value from. There are no more forms evaluated after the form in the tail position is evaluated. Consider this example from The Joy of Clojure (defn absolute-value [x] (if (pos? x) x ; “then” clause (- x))) ; “else” clause It takes a … Read more
Please review Appendix B: Operators and Symbols of The Rust Programming Language. In this case, the double colon (::) is the path separator. Paths are comprised of crates, modules, and items. The full path for your example item, updated for 1.0 is: std::usize::BITS Here, std is the crate, usize is a module, and BITS is … Read more
if your default operator is OR, then you can just give the query as sharedTo:(‘foo’ ‘bar’) If your default operator is AND, then you’ll have to do it like this: sharedTo:(foo OR bar)
It’s to avoid triggering warnings if the open shadows an exisiting identifier. See the manual.
