Golang: Convert JSON to Struct
Golang: Convert JSON in to a useful struct. Raw JSON Input { "example": { "from": { "json": true } } } Go Struct Output package main type MyJsonName struct { Example struct { From struct { JSON bool `json:"json"` } `json:"from"` } `json:"example"` } Notes: Also supports loading from remote json via the src param. Example: http://json2struct.mervine.net?src=http://json2struct.mervine.net/example.js
go fmt your code - The Go Programming Language
Andrew Gerrand 23 January 2013 Introduction Gofmt is a tool that automatically formats Go source code. Gofmt’d code is: easier to write: never worry about minor formatting concerns while hacking away, easier to read: when all code looks the same you need not mentally convert others’ formatting style into something you can understand. easier to maintain: mechanical changes to the source don’t cause
cannot convert data (type interface {}) to type string: need type assertion
I am pretty new to go and I was playing with this notify package. At first I had code that looked like this: func doit(w http.ResponseWriter, r *http.Request) { notify.Post("my_event", "Hello World!") fmt.Fprint(w, "+OK") } I wanted to append newline to Hello World! but not in the function doit above, because that would be pretty trivial, but in the handler afterwards like this below: func handler
The Go Programming Language Specification - The Go Programming Language
Introduction This is the reference manual for the Go programming language. The pre-Go1.18 version, without generics, can be found here. For more information and other documents, see go.dev. Go is a general-purpose language designed with systems programming in mind. It is strongly typed and garbage-collected and has explicit support for concurrent programming. Programs are constructed from packages
research!rsc: Go Data Structures
When explaining Go to new programmers, I've found that it often helps to explain what Go values look like in memory, to build the right intuition about which operations are expensive and which are not. This post is about basic types, structs, arrays, and slices. Basic types Let's start with some simple examples: The variable i has type int, represented in memory as a single 32-bit word. (All these
Text normalization in Go - The Go Programming Language
Go’s approach to normalization As mentioned in the strings blog post, Go does not guarantee that characters in a string are normalized. However, the go.text packages can compensate. For example, the collate package, which can sort strings in a language-specific way, works correctly even with unnormalized strings. The packages in go.text do not always require normalized input, but in general normal
Understanding Slices in Go Programming
August 15, 2013Understanding Slices in Go Programming Since I started programming in Go the concept and use of slices has been confusing. This is something completely new to me. They look like an array, and feel like an array, but they are much more than an array. I am constantly reading how slices are used quite a bit by Go programmers and I think it is finally time for me to understand what slic
Go at Google: Language Design in the Service of Software Engineering - The Go Programming Language
1. Abstract (This is a modified version of the keynote talk given by Rob Pike at the SPLASH 2012 conference in Tucson, Arizona, on October 25, 2012.) The Go programming language was conceived in late 2007 as an answer to some of the problems we were seeing developing software infrastructure at Google. The computing landscape today is almost unrelated to the environment in which the languages being

Effective Go - The Go Programming Language
Introduction Go is a new language. Although it borrows ideas from existing languages, it has unusual properties that make effective Go programs different in character from programs written in its relatives. A straightforward translation of a C++ or Java program into Go is unlikely to produce a satisfactory result—Java programs are written in Java, not Go. On the other hand, thinking about the prob

実践Go言語 - golang.jp
Go言語とは、Googleが開発した新しいプログラミング言語です。 当サイトではこの新しい言語についての情報を集約していきます。 このサイトの更新が滞っており、情報が古くなっておりますのでご注意ください。 はじめに Goは新しい言語です。既存の言語からアイデアを取り入れてはいますが、他の言語にはない機能をもっているため、実際に記述されたGoのプログラムは、他の類似した言語とはだいぶ異なるものになります。C++またはJavaプログラムをGo言語へ直接変換しても、あまりうまくは行きません。JavaのプログラムはあくまでJavaで書かれており、Go言語で書かれてはいないからです。一方で、Go側の視点からこの問題を考えると、変換に成功したとしても、全く違うプログラムができてしまうことになります。言い換えると、Go言語を使いこなすには、Go言語の機能や文法を理解することが重要です。おなじく、Go言語
