phpcs: How can I modify PSR2 to check that the brace is on the same line as the method?

阅读更多关于 phpcs: How can I modify PSR2 to check that the brace is on the same line as the method?

问题 I've spent now over 2h on trying to figure out how to require the { in the same line as the method declaration instead of the default requirement being the next line. How can I get this done? I've copied the PSR2 standard to a new folder named PSR2 to be ably to modify it to my liking. So the base I'm working on is basically the PSR2 standard which I would like to modify.

阅读更多关于 Convention result and code error C++ int foo (…)

问题 In Linux for example when i use batch if error code is 0 thats good, but what is the convention in C++ ? when int (or bool) is equal to one we say that's true, but what must be the return of such function in C++ ? 回答1: In C++ it is common to use boolean return to indicate true for success, and false for failure.

阅读更多关于 Dynamically add rules to CSS file

问题 For each element I want to dynamically add a rule to my CSS. Each rule should have different background-image and different name. Don't know where I have made a mistake.
