SVG container renders wrong size in Safari desktop (fine in Chrome/iOS)

阅读更多关于 SVG container renders wrong size in Safari desktop (fine in Chrome/iOS)

问题 I thought Safari had sorted this but it still seems to be an issue (unless I'm doing something obviously wrong). I have a SVG placed inside an object tag. That is wrapped in a flexible containing DIV (e.g set to be width 50%). On resize, the container height resizes in Firefox, Chrome and Opera as I would expect but on Safari the container stays too high. Here's an example on Codepen to demonstrate, switch to the full size result or 'editor on side' (button bottom right) to see the effect

Is a C++ optimizer allowed to move statements across a function call?

阅读更多关于 Is a C++ optimizer allowed to move statements across a function call?

问题 Note: No multithreading at all here. Just optimized single-threaded code. A function call introduces a sequence point. (Apparently.) Does it follow that a compiler (if the optimizer inlines the function) is not allowed to move/intermingle any instructions prior/after with the function's instructions? (As long as it can "proove" no observable effects obviously.) Explanatory background: Now, there is a nice article wrt. a benchmarking class for C++, where the author stated: The code we time won

Behavior of LINE in inline functions

问题 I have a macro that passes the line number and file name to an error handler: #define SYSTEM_FAILURE (error_code, comment) \ System_Failure((error_code), (comment), __LINE__, __FILE__); How will the __LINE__ be resolved when used inside an inlined function? file.h: inline int divide(int x, int y) { if (y == 0) { SYSTEM_FAILURE(ENUM_DIVIDE_BY_ZERO, "divide by zero error"); } return x/y; } Will __LINE__ contain the line number within the header file, or the line number of the source file where

Different implementations of inline functions in different translation units

阅读更多关于 Different implementations of inline functions in different translation units

The C++ standard says this about ODR, as it applies to inline functions (emphasis mine): 3.2 One definition rule 3 Every program shall contain exactly one definition of every non-inline function or variable that is odr-used in that program; no diagnostic required. The definition can appear explicitly in the program, it can be found in the standard or a user-defined library, or (when appropriate) it is implicitly defined (see 12.1, 12.4 and 12.8). An inline function shall be defined in every translation unit in which it is odr-used . It doesn't say anything about whether the inline functions

Inline functions mechanism

阅读更多关于 Inline functions mechanism

I know that an inline function does not use the stack for copying the parameters but it just replaces the body of the function wherever it is called. Consider these two functions: inline void add(int a) { a++; } // does nothing, a won't be changed inline void add(int &a) { a++; } // changes the value of a If the stack is not used for sending the parameters, how does the compiler know if a variable will be modified or not? What does the code looks like after replacing the calls of these two functions? What makes you think there is a stack ? And even if there is, what makes you think it would be

CSS中 inline、block、inline-block的区别

阅读更多关于 CSS中 inline、block、inline-block的区别

我们用firbug浏览别人网站时会发现设计者会在很多地方使用inline-block。我们都知道 inline是声明div是内联对象，block是声明块对象，那么inline-block是什么意思，即内联又成块？接下来做个测试，让我们了解一下三者的区别和作用吧： 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 <htmlxmlns=" http://www.w3.org/1999/xhtml "> <head> <metahttp-equiv="Content-Type"content="text/html; charset=utf-8"/> <title>inline、block、inline-block的区别</title> <style> .a{display:inline; width:100px; height:100px; padding:5px; background-color:#F00;} .b{display:block; width:100px; height:100px; padding:5px;background-color:#0f0;} .c{display:inline-block; width:100px;height:100px; padding:5px;background

inline-block 前世今生

曾几何时，display:inline-block 已经深入「大街小巷」，随处可见「display:inline-block; *display:inline; *zoom:1; 」这样的代码。如今现代浏览器已经全面支持这个属性值了，上面的代码只是为了兼容 IE6、7 而已。那么你真的了解 inline-block 了吗？本文将带你深入剖析该属性值的前世今生，让你更好的理解和运用 inline-block。（本文约定 display:inline-block 简写为 inline-block）开篇我们来看几个问题： IE6、7 真的不支持 display:inline-block 吗？ display:inline-block 后的元素为什么会产生水平空隙，这真的是 bug 吗？如何更好的解决 display:inline-block 元素间产生的水平空隙？一、inline-block 前世 1.认知也许有人问你为何要写「 display:inline-block; *display:inline; *zoom:1; 」来兼容 IE6、7 时，你会立马答道：因为 IE6、7 不支持 display:inline-block 呗!不知道何时起，惯性思维给开发者带来了这样一个可怕的概念。万物都是辩证的，当你写下这些的时候，可曾怀疑过大众观点真的可靠吗？也许你认为这些无关

static and inline

Iam programing in C. I want some description about static and inline functions. I know that if we make a function static then it is an indication to compiler that it is under internal linkage for only one translation unit. I have following doubts regarding static and inline : If we make a function as static , can we use it in other translation units ...i.e in other .c files? If yes ..how? If we make the function as static inline what is the difference then ? How it will be treated by the compiler ? Does making a function as static gives the same effect as a macro? Treating a function to be

%matplotlib inline

阅读更多关于 %matplotlib inline

%matplotlib inline比较奇怪，而且无论你是用哪个python的IDE如spyder或者pycharm,这个地方都会报错，显示是invalid syntax（无效语法）。那为什么代码里面还是会有这一句呢？ %matplotlib作用是在使用jupyter notebook 或者 jupyter qtconsole的时候，才会经常用到%matplotlib，也就是说那一份代码可能就是别人使用jupyter notebook 或者 jupyter qtconsole进行编辑的。关于jupyter notebook是什么，可以参考这个链接：[Jupyter Notebook介绍、安装及使用教程][1] 而%matplotlib具体作用是当你调用matplotlib.pyplot的绘图函数plot()进行绘图的时候，或者生成一个figure画布的时候，可以直接在你的python console里面生成图像。而我们在spyder或者pycharm实际运行代码的时候，可以直接注释掉这一句，也是可以运行成功的。链接：https://www.jianshu.com/p/2dda5bb8ce7d 来源： https://www.cnblogs.com/Allen-rg/p/11991873.html
