I don’t inline anything until a profiler has specifically told me that not inlining is resulting in a performance problem. The C++ compiler is very smart and will almost certainly automatically inline such simple function like this for you. And typically it’s smarter than you are and will do a much better job at determining … Read more
I will try to explain my “secret understanding” the best way I can. There are two entirely separate concepts here. One is the compiler’s ability to replace a function call by repeating the function body directly at the call site. The other is the possibility of defining a function in more than one translation unit … Read more
$(‘div’).attr(‘style’, ”); or $(‘div’).removeAttr(‘style’); (From Andres’s Answer) To make this a little smaller, try this: $(‘div[style]’).removeAttr(‘style’); This should speed it up a little because it checks that the divs have the style attribute. Either way, this might take a little while to process if you have a large amount of divs, so you might want … Read more
Use Java 8 Optional (no filter needed): public static String orElse(String defaultValue) { return Optional.ofNullable(System.getProperty(“property”)).orElse(defaultValue); }
C++ is object oriented, in the sense that it supports the object oriented paradigm for software development. However, differently from Java, C++ doesn’t force you to group function definitions in classes: the standard C++ way for declaring a function is to just declare a function, without any class. If instead you are talking about method … Read more
You can, using CSS variables (more precisely called CSS custom properties). Set your variable in your style attribute: style=”–my-color-var: orange;” Use the variable in your stylesheet: background-color: var(–my-color-var); Browser compatibility Minimal example: div { width: 100px; height: 100px; position: relative; border: 1px solid black; } div:after { background-color: var(–my-color-var); content: ”; position: absolute; top: 0; … Read more
This works: python -c ‘print(“Hi”)’ Hi From the manual, man python: -c command Specify the command to execute (see next section). This termi- nates the option list (following options are passed as arguments to the command).
Actually this excellent answer also answers your question, I think: What does extern inline do? The idea is that “inline” can be used in a header file, and then “extern inline” in a .c file. “extern inline” is just how you instruct the compiler which object file should contain the (externally visible) generated code. [update, … Read more
One limitation of the current Rust compiler is that it if you’re not using LTO (Link-Time Optimization), it will never inline a function not marked #[inline] across crates. Rust uses a separate compilation model similar to C++ because LLVM’s LTO implementation doesn’t scale well to large projects. Therefore, small functions exposed to other crates need … Read more
The problem is that the min3 function is compiled as a generic function that uses generic comparison (I thought this uses just IComparable, but it is actually more complicated – it would use structural comparison for F# types and it’s fairly complex logic). > let min3(a, b, c) = min a (min b c);; val … Read more
