At the time of Go's inception, only a decade ago, binary options derivation, the programming world was different from today. Meanwhile, we had become frustrated by the undue complexity required to use the languages we worked with to develop server software.
Also, it was clear that multiprocessors were becoming universal but most languages offered little help to program them efficiently and safely. We decided to take a step back and think about what major issues were going to dominate software engineering in the years ahead as technology developed, and how a new language might help address them.
For instance, the rise of multicore CPUs argued that a language should provide first-class support for some sort of concurrency or parallelism. And to make resource management tractable in a large concurrent program, garbage collection, or at least some sort of safe automatic memory management was required. These considerations led to a series of discussions from which Go arose, first as a set of ideas and desiderata, then as a language. An overarching goal was that Go do more to help the working programmer by enabling tooling, automating mundane tasks such as code formatting, and removing obstacles to working on large code bases.
A much more expansive description of the goals of Go and how they are met, or at least approached, binary options derivation, is available in the article, Go at Google: Language Design in the Service of Software Engineering. Robert Griesemer, Rob Pike and Ken Thompson started sketching the goals for a new language on the white board on September 21, Within a few days the goals had settled into a plan to do something and a fair idea of what it would be.
Design continued part-time in parallel with unrelated work. By JanuaryKen had started work on a compiler with which to explore ideas; it generated C code as its output. By mid-year the language had become a full-time project and had settled enough to attempt a production compiler. In MayIan Taylor independently started on a GCC front end for Go using the draft specification.
Russ Cox joined in late and helped move the language and libraries from prototype to reality. Go became a public open source project on November 10, Countless people from the community have contributed ideas, binary options derivation, discussions, and code. There are now millions of Go programmers—gophers—around the world, and there are more every day. Go's success has far exceeded our expectations.
The mascot and logo were designed by Renée Frenchwho also designed Glendabinary options derivation, the Plan 9 bunny. A blog post about the gopher explains how binary options derivation was derived from one she used for a WFMU T-shirt design some years ago.
The logo and mascot are covered by the Creative Commons Attribution 3. The gopher has a model sheet illustrating his characteristics and how to represent them correctly. The model sheet was first shown in a talk by Renée at Gophercon in He has unique features; he's the Go gophernot just any old gopher. The language is called Go. The "golang" moniker arose because the web site is golang, binary options derivation.
orgnot go. org, which was not available to us. Many use the golang name, though, and it is handy as a label.
For instance, the Twitter tag for the language is " golang". The language's name is just plain Go, regardless. A side note: Although the official logo has two capital letters, the language name is written Go, not GO. Go was born out of frustration with existing languages and environments for the work we were doing at Google. Programming had become binary options derivation difficult and the choice of languages was partly to blame.
One had to choose either efficient compilation, efficient execution, or ease of programming; all three were not available in the same mainstream language. We were not alone in our concerns. After many years with a pretty quiet landscape for programming languages, binary options derivation, Go was among the first binary options derivation several new languages—Rust, Elixir, Swift, and more—that have made programming language development an active, almost mainstream field again.
Go addressed these issues by attempting to combine the ease of programming of binary options derivation interpreted, dynamically typed language with the efficiency and safety of a statically typed, compiled language, binary options derivation. It also aimed to be modern, with support for networked and multicore computing. Finally, working with Go is intended to be fast : it should take at most a few seconds to build a large executable on a single computer.
To meet these goals required addressing a number of linguistic issues: an expressive but lightweight type system; concurrency and garbage collection; rigid dependency specification; and so on. These cannot be addressed well by libraries or tools; a new language was called for.
The article Go at Google discusses the background and motivation behind the design of the Go language, as well as providing more detail about many of the answers binary options derivation in this FAQ. However, it is a new language across the board. In every respect the language was designed by thinking about what programmers do and how to make programming, at least the kind of programming we do, more effective, which means more fun. We binary options derivation that these languages required too much bookkeeping and repetition.
Some programmers reacted by moving towards more dynamic, binary options derivation, fluid languages like Python, at the cost of efficiency and type safety.
We felt it should be possible to have the efficiency, the safety, binary options derivation, and the fluidity in a single language. Go attempts to reduce the amount of typing in both senses binary options derivation the word. Throughout its design, we have tried to reduce clutter and complexity. There are no forward declarations and no header files; everything is declared exactly once. Initialization is expressive, automatic, and easy to use.
Syntax is clean and light on keywords. Repetition foo. And perhaps most radically, there is no type hierarchy: types just arethey don't have to announce their relationships. These simplifications allow Go to be expressive yet comprehensible without sacrificing, well, sophistication.
Another important principle is to keep the concepts orthogonal. Methods can be implemented for any type; structures represent data while interfaces represent abstraction; and so on. Orthogonality makes it easier to understand what happens when things combine.
Go is used widely in production inside Google. One easy example is the server behind golang. It's just the godoc document server running in a production configuration on Google App Engine. A more significant instance is Google's download server, dl. comwhich delivers Chrome binaries and other large installables such as apt-get packages. Go is not the only language used at Google, binary options derivation, far from it, but it is a key language for a number of areas including site reliability engineering SRE and large-scale data processing.
Go usage is growing worldwide, especially but by no means exclusively in the cloud computing space. A couple of major cloud infrastructure projects written in Go are Docker and Kubernetes, but there are many more.
It's not just cloud, though. The Go Wiki includes a pageupdated regularly, that lists some of the many companies using Go. Binary options derivation Wiki also has a page with links to success stories about companies and projects that are using the language.
It is possible to use C and Go together in the same address space, but it is not a natural fit and can require special interface software. Also, linking C with Go code gives up the memory safety and stack management properties that Go provides.
Sometimes it's absolutely necessary to use C libraries to solve a problem, but doing so always introduces an element of risk not present with pure Go code, so do so with care.
If you do need to use C with Go, how to proceed depends on the Go compiler implementation. There are three Go compiler implementations supported by the Go team. These are gcthe default compiler, gccgowhich uses the GCC back end, and a somewhat less mature gollvmbinary options derivation uses the LLVM infrastructure. Gc uses a different calling convention and linker from C and therefore cannot be called directly from C programs, or vice versa, binary options derivation.
You can also use cgo and SWIG with Gccgo and gollvm. The Go project does not include a custom IDE, but the language and libraries have been designed to make it easy to analyze source code. As a consequence, most well-known editors and IDEs support Go well, either directly or through a plugin.
The list of well-known IDEs and editors that have good Go support available includes Emacs, Vim, VSCode, Atom, Eclipse, Sublime, IntelliJ through a custom variant called Golandand many more.
Chances are your favorite environment is a productive one for programming in Go. A separate open source project provides the necessary binary options derivation plugin and library. It is available at github, binary options derivation. We encourage developers to make Go Language sites in their own languages. However, if you choose to add the Google logo or branding to your site it does not appear on golang. orgyou will need to abide by the guidelines at www.
Go does have an extensive library, called the runtimethat is part of every Go program. The runtime library implements garbage collection, concurrency, stack management, and other critical features of the Go language.
Although it is more central to the language, Go's runtime is analogous to libcthe C library. It is important to understand, however, that Go's runtime does not include a virtual machine, such binary options derivation is provided by the Java runtime. Go programs are compiled ahead of time to native machine code or JavaScript or WebAssembly, for some variant implementations.
When designing Go, we wanted to make sure that it was not overly ASCII-centric, which meant extending the space of identifiers from the confines of 7-bit ASCII.
Go's rule—identifier characters must be letters or digits as defined by Unicode—is simple to understand and to implement but has restrictions. Combining characters are excluded by design, for instance, and that excludes some languages such as Devanagari.
This rule has one other unfortunate consequence. Since an exported identifier must begin with an upper-case letter, identifiers created from characters in some languages can, by definition, not be exported.
