有两个常用的传入参数的类型。一个是struct,在模板内可以读取该struct域的内容来进行渲染。还有一个是map[string]interface{},在模板内可以使用key来进行渲染。 我一般使用第二种,效率可能会差一点儿,但是用着方便。 模板内内嵌的语法支持,全部需要加{{}}来标记。 在模板文件内, . 代表了当前变量,即在非循环...
for a C programmer). I'd suggest you create a wrapper function in C (or Go) to create the structure for you. for printing, you can define the String method on real type of structure (it won't be portable, as it depends the real type name of the C struct, but it's certainly do...
Let's start by defining the data structures. A wiki consists of a series of interconnected pages, each of which has a title and a body (the page content). Here, we definePageas a struct with two fields representing the title and body. ...
在汇编文件中可以定义、引用宏。通过#define get_tls(r) MOVQ TLS, r类似语句来定义一个宏,语法结构与C语言类似;通过#include "textflag.h"类似语句来引用一个外部宏定义文件。 go编译器为了方便汇编中访问struct的指定字段,会在编译过程中自动生成一个go_asm.h文件,可以通过#include "go_asm.h"语言来引用,该...

In this code, we define a Thing struct with two fields, Name and Num. The struct has a receiver function, Init, which sets the values of these fields based on the parameters provided. In the main function, we create a new instance of the Thing struct using the new keyword and subsequen...
The code above comes from the quick js library. The goal is to use a macro to define that initializes a struct. What did you expect to see? I expected this code to compile on Linux, like it does on MacOS. What did you see instead?
