A new Go API for Protocol Buffers - The Go Programming Language
Joe Tsai, Damien Neil, and Herbie Ong 2 March 2020 Introduction We are pleased to announce the release of a major revision of the Go API for protocol buffers, Google’s language-neutral data interchange format. Motivations for a new API The first protocol buffer bindings for Go were announced by Rob Pike in March of 2010. Go 1 would not be released for another two years. In the decade since that fi
Working with Errors in Go 1.13 - The Go Programming Language
Damien Neil and Jonathan Amsterdam 17 October 2019 Introduction Go’s treatment of errors as values has served us well over the last decade. Although the standard library’s support for errors has been minimal—just the errors.New and fmt.Errorf functions, which produce errors that contain only a message—the built-in error interface allows Go programmers to add whatever information they desire. All i

Module Mirror and Checksum Database Launched - The Go Programming Language
Katie Hockman 29 August 2019 We are excited to share that our module mirror, index, and checksum database are now production ready! The go command will use the module mirror and checksum database by default for Go 1.13 module users. See proxy.golang.org/privacy for privacy information about these services and the go command documentation for configuration details, including how to disable the use
Generating code - The Go Programming Language
Rob Pike 22 December 2014 A property of universal computation—Turing completeness—is that a computer program can write a computer program. This is a powerful idea that is not appreciated as often as it might be, even though it happens frequently. It’s a big part of the definition of a compiler, for instance. It’s also how the go test command works: it scans the packages to be tested, writes out a
Profiling Go Programs - The Go Programming Language
Russ Cox, July 2011; updated by Shenghou Ma, May 2013 24 June 2011 At Scala Days 2011, Robert Hundt presented a paper titled Loop Recognition in C++/Java/Go/Scala. The paper implemented a specific loop finding algorithm, such as you might use in a flow analysis pass of a compiler, in C++, Go, Java, Scala, and then used those programs to draw conclusions about typical performance concerns in these
Compile-time Dependency Injection With Go Cloud's Wire - The Go Programming Language
Robert van Gent 9 October 2018 Overview The Go team recently announced the open source project Go Cloud, with portable Cloud APIs and tools for open cloud development. This post goes into more detail about Wire, a dependency injection tool used in Go Cloud. What problem does Wire solve? Dependency injection is a standard technique for producing flexible and loosely coupled code, by explicitly prov
The Laws of Reflection - The Go Programming Language
Rob Pike 6 September 2011 Introduction Reflection in computing is the ability of a program to examine its own structure, particularly through types; it’s a form of metaprogramming. It’s also a great source of confusion. In this article we attempt to clarify things by explaining how reflection works in Go. Each language’s reflection model is different (and many languages don’t support it at all), b
