Why can't you name a function in Go “init”?

由 久未见 提交于 2019-12-10 01:23:37
问题 So, today while I was coding I found out that creating a function with the name init generated an error method init() not found , but when I renamed it to startup it all worked fine. Is the word "init" preserved for some internal operation in Go or am I'm missing something here? 回答1: Yes, the function init() is special. It is automatically executed when a package is loaded. Even the package main may contain one or more init() functions that are executed before the actual program begins: http:

VS Express 2013 for Web: How to use the internal VS server, not IIS express?

由 旧巷老猫 提交于 2019-12-08 16:51:38
问题 I switched to Visual Studio Express 2013 for Web, but I've just stumbeled into something. It's default settings are set so that it uses IIS Express as a default web server, and there isn't a button that could change that, as in VS Express 2012 for Web before. I was looking for that option in the settings and in the properties / property page for my project, but I can't find it. 回答1: It's been discontinued. The options are IIS Express or IIS. And that's for the full range of the product, not
