$ go install golang.org/x/website/tour@latest · This will place the tour binary in your GOPATH's bin directory. A document that gives tips for writing clear, idiomatic Go code. A must read for any new Go programmer. It augments the tour and the language specification, both of which should be read first.

March 31, 2011 - The convention is simple: to document a type, variable, constant, function, or even a package, write a regular comment directly preceding its declaration, with no intervening blank line. Godoc will then present that comment as text alongside the item it documents.

To document a function, type, constant, variable, or even a complete package, write a regular comment directly preceding its declaration, with no blank line in between. For example, this is the documentation for the fmt.Println function:

This means a user of the data structure can create one with new and get right to work. For example, the documentation for bytes.Buffer states that "the zero value for Buffer is an empty buffer ready to use." Similarly, sync.Mutex does not have an explicit constructor or Init method.

Go is an open source programming language designed for building scalable, secure and reliable software. Please read the official documentation to learn more. Go by Example is a hands-on introduction to Go using annotated example programs.

March 11, 2024 - Let’s look into the comments in this sample code and what the generated documentation looks like: ... The title or short description should be the first comment for the package without any new lines between the comment and the package definition. Long description Starts after topic sentences after a new line. Can contain as many paragraphs and sections as we want. Sub-sections/headings Starts with “#” and is displayed as a sub-heading · Code Examples If we indent anything in the description section, it is displayed inside a block, whether it is code or not.

Go, often referred to as Golang, is a modern programming language developed by Google. Thanks to its efficiency, simplicity, and robust support for concurrency, Go has become a popular choice for developing scalable web servers, cloud services, and command-line tools.

Directive comments such as //go:generate are not considered part of a doc comment and are omitted from rendered documentation. Gofmt moves directive comments to the end of the doc comment, preceded by a blank line. For example:

How to use godoc for documenting your Go packages? Explained with examples - amalmadhu06/godoc-example

May 7, 2015 - $ go test -v === RUN TestString --- PASS: TestString (0.00s) PASS ok golang.org/x/example/hello/reverse 0.110s · Examples without output comments are useful for demonstrating code that cannot run as unit tests, such as that which accesses the network, while guaranteeing the example at least compiles. Godoc uses a naming convention to associate an example function with a package-level identifier. func ExampleFoo() // documents the Foo function or type func ExampleBar_Qux() // documents the Qux method of type Bar func Example() // documents the package as a whole

$ go mod init example/hello go: creating new go.mod: module example/hello

271 for _, c := range file.Comments { 272 if body.Pos() <= c.Pos() && c.End() <= body.End() { 273 comments = append(comments, c) 274 } 275 } 276 277 // Strip the "Output:" or "Unordered output:" comment and adjust body 278 // end position. 279 body, comments = stripOutputComment(body, comments) 280 281 // Include documentation belonging to dependent declarations.

Source code is Unicode text encoded in UTF-8. The text is not canonicalized, so a single accented code point is distinct from the same character constructed from combining an accent and a letter; those are treated as two code points. For simplicity, this document will use the unqualified term character to refer to a Unicode code point in the source text.

Godoc example. GitHub Gist: instantly share code, notes, and snippets.

type Example struct { Name string // name of the item being exemplified Doc string // example function doc string Code ast.Node Comments []*ast.CommentGroup Output string // expected output }

A span of unindented non-blank lines defines link targets when every line is of the form “[Text]: URL”. In other text in the same doc comment, “[Text]” represents a link to URL using the given text—in HTML, <a href=“URL”>Text</a>. For example: // Package json implements encoding and decoding of JSON as defined in // [RFC 7159]. The mapping between JSON and Go values is described // in the documentation for the Marshal and Unmarshal functions. // // For an introduction to this package, see the article // “[JSON and Go].” // // [RFC 7159]: https://tools.ietf.org/html/rfc7159 // [JSON and Go]: https://golang.org/doc/articles/json_and_go.html package json
