    Compile packages and dependencies

    +

    +Usage: +

    +
    go build [-o output] [-i] [build flags] [packages]
+
    +

    +Build compiles the packages named by the import paths, +along with their dependencies, but it does not install the results. +

    +

    +If the arguments to build are a list of .go files, build treats +them as a list of source files specifying a single package. +

    +

    +When compiling a single main package, build writes +the resulting executable to an output file named after +the first source file ('go build ed.go rx.go' writes 'ed' or 'ed.exe') +or the source code directory ('go build unix/sam' writes 'sam' or 'sam.exe'). +The '.exe' suffix is added when writing a Windows executable. +

    +

    +When compiling multiple packages or a single non-main package, +build compiles the packages but discards the resulting object, +serving only as a check that the packages can be built. +

    +

    +When compiling packages, build ignores files that end in '_test.go'. +

    +

    +The -o flag, only allowed when compiling a single package, +forces build to write the resulting executable or object +to the named output file, instead of the default behavior described +in the last two paragraphs. +

    +

    +The -i flag installs the packages that are dependencies of the target. +

    +

    +The build flags are shared by the build, clean, get, install, list, run, +and test commands: +

    +
    -a
+	force rebuilding of packages that are already up-to-date.
+-n
+	print the commands but do not run them.
+-p n
+	the number of programs, such as build commands or
+	test binaries, that can be run in parallel.
+	The default is the number of CPUs available.
+-race
+	enable data race detection.
+	Supported only on linux/amd64, freebsd/amd64, darwin/amd64 and windows/amd64.
+-msan
+	enable interoperation with memory sanitizer.
+	Supported only on linux/amd64,
+	and only with Clang/LLVM as the host C compiler.
+-v
+	print the names of packages as they are compiled.
+-work
+	print the name of the temporary work directory and
+	do not delete it when exiting.
+-x
+	print the commands.
+
+-asmflags 'flag list'
+	arguments to pass on each go tool asm invocation.
+-buildmode mode
+	build mode to use. See 'go help buildmode' for more.
+-compiler name
+	name of compiler to use, as in runtime.Compiler (gccgo or gc).
+-gccgoflags 'arg list'
+	arguments to pass on each gccgo compiler/linker invocation.
+-gcflags 'arg list'
+	arguments to pass on each go tool compile invocation.
+-installsuffix suffix
+	a suffix to use in the name of the package installation directory,
+	in order to keep output separate from default builds.
+	If using the -race flag, the install suffix is automatically set to race
+	or, if set explicitly, has _race appended to it.  Likewise for the -msan
+	flag.  Using a -buildmode option that requires non-default compile flags
+	has a similar effect.
+-ldflags 'flag list'
+	arguments to pass on each go tool link invocation.
+-linkshared
+	link against shared libraries previously created with
+	-buildmode=shared.
+-pkgdir dir
+	install and load all packages from dir instead of the usual locations.
+	For example, when building with a non-standard configuration,
+	use -pkgdir to keep generated packages in a separate location.
+-tags 'tag list'
+	a list of build tags to consider satisfied during the build.
+	For more information about build tags, see the description of
+	build constraints in the documentation for the go/build package.
+-toolexec 'cmd args'
+	a program to use to invoke toolchain programs like vet and asm.
+	For example, instead of running asm, the go command will run
+	'cmd args /path/to/asm <arguments for asm>'.
+
    +

    +The list flags accept a space-separated list of strings. To embed spaces +in an element in the list, surround it with either single or double quotes. +

    +

    +For more about specifying packages, see 'go help packages'. +For more about where packages and binaries are installed, +run 'go help gopath'. +For more about calling between Go and C/C++, run 'go help c'. +

    +

    +Note: Build adheres to certain conventions such as those described +by 'go help gopath'. Not all projects can follow these conventions, +however. Installations that have their own conventions or that use +a separate software build system may choose to use lower-level +invocations such as 'go tool compile' and 'go tool link' to avoid +some of the overheads and design decisions of the build tool. +

    Remove object files

    +

    +Usage: +

    +
    go clean [-i] [-r] [-n] [-x] [build flags] [packages]
+
    +

    +Clean removes object files from package source directories. +The go command builds most objects in a temporary directory, +so go clean is mainly concerned with object files left by other +tools or by manual invocations of go build. +

    +

    +Specifically, clean removes the following files from each of the +source directories corresponding to the import paths: +

    +
    _obj/            old object directory, left from Makefiles
+_test/           old test directory, left from Makefiles
+_testmain.go     old gotest file, left from Makefiles
+test.out         old test log, left from Makefiles
+build.out        old test log, left from Makefiles
+*.[568ao]        object files, left from Makefiles
+
+DIR(.exe)        from go build
+DIR.test(.exe)   from go test -c
+MAINFILE(.exe)   from go build MAINFILE.go
+*.so             from SWIG
+
    +

    +In the list, DIR represents the final path element of the +directory, and MAINFILE is the base name of any Go source +file in the directory that is not included when building +the package. +

    +

    +The -i flag causes clean to remove the corresponding installed +archive or binary (what 'go install' would create). +

    +

    +The -n flag causes clean to print the remove commands it would execute, +but not run them. +

    +

    +The -r flag causes clean to be applied recursively to all the +dependencies of the packages named by the import paths. +

    +

    +The -x flag causes clean to print remove commands as it executes them. +

    +

    +

    Show documentation for package or symbol

    +

    +Usage: +

    +
    go doc [-u] [-c] [package|[package.]symbol[.method]]
+
    +

    +Doc prints the documentation comments associated with the item identified by its +arguments (a package, const, func, type, var, or method) followed by a one-line +summary of each of the first-level items "under" that item (package-level +declarations for a package, methods for a type, etc.). +

    +

    +Doc accepts zero, one, or two arguments. +

    +

    +Given no arguments, that is, when run as +

    +
    go doc
+
    +

    +it prints the package documentation for the package in the current directory. +If the package is a command (package main), the exported symbols of the package +are elided from the presentation unless the -cmd flag is provided. +

    +

    +When run with one argument, the argument is treated as a Go-syntax-like +representation of the item to be documented. What the argument selects depends +on what is installed in GOROOT and GOPATH, as well as the form of the argument, +which is schematically one of these: +

    +
    go doc <pkg>
+go doc <sym>[.<method>]
+go doc [<pkg>.]<sym>[.<method>]
+go doc [<pkg>.][<sym>.]<method>
+
    +

    +The first item in this list matched by the argument is the one whose documentation +is printed. (See the examples below.) However, if the argument starts with a capital +letter it is assumed to identify a symbol or method in the current directory. +

    +

    +For packages, the order of scanning is determined lexically in breadth-first order. +That is, the package presented is the one that matches the search and is nearest +the root and lexically first at its level of the hierarchy. The GOROOT tree is +always scanned in its entirety before GOPATH. +

    +

    +If there is no package specified or matched, the package in the current +directory is selected, so "go doc Foo" shows the documentation for symbol Foo in +the current package. +

    +

    +The package path must be either a qualified path or a proper suffix of a +path. The go tool's usual package mechanism does not apply: package path +elements like . and ... are not implemented by go doc. +

    +

    +When run with two arguments, the first must be a full package path (not just a +suffix), and the second is a symbol or symbol and method; this is similar to the +syntax accepted by godoc: +

    +
    go doc <pkg> <sym>[.<method>]
+
    +

    +In all forms, when matching symbols, lower-case letters in the argument match +either case but upper-case letters match exactly. This means that there may be +multiple matches of a lower-case argument in a package if different symbols have +different cases. If this occurs, documentation for all matches is printed. +

    +

    +Examples: +

    +
    go doc
+	Show documentation for current package.
+go doc Foo
+	Show documentation for Foo in the current package.
+	(Foo starts with a capital letter so it cannot match
+	a package path.)
+go doc encoding/json
+	Show documentation for the encoding/json package.
+go doc json
+	Shorthand for encoding/json.
+go doc json.Number (or go doc json.number)
+	Show documentation and method summary for json.Number.
+go doc json.Number.Int64 (or go doc json.number.int64)
+	Show documentation for json.Number's Int64 method.
+go doc cmd/doc
+	Show package docs for the doc command.
+go doc -cmd cmd/doc
+	Show package docs and exported symbols within the doc command.
+go doc template.new
+	Show documentation for html/template's New function.
+	(html/template is lexically before text/template)
+go doc text/template.new # One argument
+	Show documentation for text/template's New function.
+go doc text/template new # Two arguments
+	Show documentation for text/template's New function.
+
+At least in the current tree, these invocations all print the
+documentation for json.Decoder's Decode method:
+
+go doc json.Decoder.Decode
+go doc json.decoder.decode
+go doc json.decode
+cd go/src/encoding/json; go doc decode
+
    +

    +Flags: +

    +
    -c
+	Respect case when matching symbols.
+-cmd
+	Treat a command (package main) like a regular package.
+	Otherwise package main's exported symbols are hidden
+	when showing the package's top-level documentation.
+-u
+	Show documentation for unexported as well as exported
+	symbols and methods.
+
    +

    Print Go environment information

    +

    +Usage: +

    +
    go env [var ...]
+
    +

    +Env prints Go environment information. +

    +

    +By default env prints information as a shell script +(on Windows, a batch file). If one or more variable +names is given as arguments, env prints the value of +each named variable on its own line. +

    +

    Start a bug report

    +

    +Usage: +

    +
    go bug
+
    +

    +Bug opens the default browser and starts a new bug report. +The report includes useful system information. +

    +

    Run go tool fix on packages

    +

    +Usage: +

    +
    go fix [packages]
+
    +

    +Fix runs the Go fix command on the packages named by the import paths. +

    +

    +For more about fix, see 'go doc cmd/fix'. +For more about specifying packages, see 'go help packages'. +

    +

    +To run fix with specific options, run 'go tool fix'. +

    +

    +See also: go fmt, go vet. +

    +

    Run gofmt on package sources

    +

    +Usage: +

    +
    go fmt [-n] [-x] [packages]
+
    +

    +Fmt runs the command 'gofmt -l -w' on the packages named +by the import paths. It prints the names of the files that are modified. +

    +

    +For more about gofmt, see 'go doc cmd/gofmt'. +For more about specifying packages, see 'go help packages'. +

    +

    +The -n flag prints commands that would be executed. +The -x flag prints commands as they are executed. +

    +

    +To run gofmt with specific options, run gofmt itself. +

    +

    +See also: go fix, go vet. +

    +

    Generate Go files by processing source

    +

    +Usage: +

    +
    go generate [-run regexp] [-n] [-v] [-x] [build flags] [file.go... | packages]
+
    +

    +Generate runs commands described by directives within existing +files. Those commands can run any process but the intent is to +create or update Go source files. +

    +

    +Go generate is never run automatically by go build, go get, go test, +and so on. It must be run explicitly. +

    +

    +Go generate scans the file for directives, which are lines of +the form, +

    +
    //go:generate command argument...
+
    +

    +(note: no leading spaces and no space in "//go") where command +is the generator to be run, corresponding to an executable file +that can be run locally. It must either be in the shell path +(gofmt), a fully qualified path (/usr/you/bin/mytool), or a +command alias, described below. +

    +

    +Note that go generate does not parse the file, so lines that look +like directives in comments or multiline strings will be treated +as directives. +

    +

    +The arguments to the directive are space-separated tokens or +double-quoted strings passed to the generator as individual +arguments when it is run. +

    +

    +Quoted strings use Go syntax and are evaluated before execution; a +quoted string appears as a single argument to the generator. +

    +

    +Go generate sets several variables when it runs the generator: +

    +
    $GOARCH
+	The execution architecture (arm, amd64, etc.)
+$GOOS
+	The execution operating system (linux, windows, etc.)
+$GOFILE
+	The base name of the file.
+$GOLINE
+	The line number of the directive in the source file.
+$GOPACKAGE
+	The name of the package of the file containing the directive.
+$DOLLAR
+	A dollar sign.
+
    +

    +Other than variable substitution and quoted-string evaluation, no +special processing such as "globbing" is performed on the command +line. +

    +

    +As a last step before running the command, any invocations of any +environment variables with alphanumeric names, such as $GOFILE or +$HOME, are expanded throughout the command line. The syntax for +variable expansion is $NAME on all operating systems. Due to the +order of evaluation, variables are expanded even inside quoted +strings. If the variable NAME is not set, $NAME expands to the +empty string. +

    +

    +A directive of the form, +

    +
    //go:generate -command xxx args...
+
    +

    +specifies, for the remainder of this source file only, that the +string xxx represents the command identified by the arguments. This +can be used to create aliases or to handle multiword generators. +For example, +

    +
    //go:generate -command foo go tool foo
+
    +

    +specifies that the command "foo" represents the generator +"go tool foo". +

    +

    +Generate processes packages in the order given on the command line, +one at a time. If the command line lists .go files, they are treated +as a single package. Within a package, generate processes the +source files in a package in file name order, one at a time. Within +a source file, generate runs generators in the order they appear +in the file, one at a time. +

    +

    +If any generator returns an error exit status, "go generate" skips +all further processing for that package. +

    +

    +The generator is run in the package's source directory. +

    +

    +Go generate accepts one specific flag: +

    +
    -run=""
+	if non-empty, specifies a regular expression to select
+	directives whose full original source text (excluding
+	any trailing spaces and final newline) matches the
+	expression.
+
    +

    +It also accepts the standard build flags including -v, -n, and -x. +The -v flag prints the names of packages and files as they are +processed. +The -n flag prints commands that would be executed. +The -x flag prints commands as they are executed. +

    +

    +For more about build flags, see 'go help build'. +

    +

    +For more about specifying packages, see 'go help packages'. +

    +

    Download and install packages and dependencies

    +

    +Usage: +

    +
    go get [-d] [-f] [-fix] [-insecure] [-t] [-u] [build flags] [packages]
+
    +

    +Get downloads the packages named by the import paths, along with their +dependencies. It then installs the named packages, like 'go install'. +

    +

    +The -d flag instructs get to stop after downloading the packages; that is, +it instructs get not to install the packages. +

    +

    +The -f flag, valid only when -u is set, forces get -u not to verify that +each package has been checked out from the source control repository +implied by its import path. This can be useful if the source is a local fork +of the original. +

    +

    +The -fix flag instructs get to run the fix tool on the downloaded packages +before resolving dependencies or building the code. +

    +

    +The -insecure flag permits fetching from repositories and resolving +custom domains using insecure schemes such as HTTP. Use with caution. +

    +

    +The -t flag instructs get to also download the packages required to build +the tests for the specified packages. +

    +

    +The -u flag instructs get to use the network to update the named packages +and their dependencies. By default, get uses the network to check out +missing packages but does not use it to look for updates to existing packages. +

    +

    +The -v flag enables verbose progress and debug output. +

    +

    +Get also accepts build flags to control the installation. See 'go help build'. +

    +

    +When checking out a new package, get creates the target directory +GOPATH/src/<import-path>. If the GOPATH contains multiple entries, +get uses the first one. For more details see: 'go help gopath'. +

    +

    +When checking out or updating a package, get looks for a branch or tag +that matches the locally installed version of Go. The most important +rule is that if the local installation is running version "go1", get +searches for a branch or tag named "go1". If no such version exists it +retrieves the most recent version of the package. +

    +

    +When go get checks out or updates a Git repository, +it also updates any git submodules referenced by the repository. +

    +

    +Get never checks out or updates code stored in vendor directories. +

    +

    +For more about specifying packages, see 'go help packages'. +

    Compile and install packages and dependencies

    +

    +Usage: +

    +
    go install [build flags] [packages]
+
    +

    +Install compiles and installs the packages named by the import paths, +along with their dependencies. +

    +

    +For more about the build flags, see 'go help build'. +For more about specifying packages, see 'go help packages'. +

    +

    +See also: go build, go get, go clean. +

    +

    List packages

    +

    +Usage: +

    +
    go list [-e] [-f format] [-json] [build flags] [packages]
+
    +

    +List lists the packages named by the import paths, one per line. +

    +

    +The default output shows the package import path: +

    +
    bytes
+encoding/json
+github.com/gorilla/mux
+golang.org/x/net/html
+
    +

    +The -f flag specifies an alternate format for the list, using the +syntax of package template. The default output is equivalent to -f +''. The struct being passed to the template is: +

    +
    type Package struct {
+    Dir           string // directory containing package sources
+    ImportPath    string // import path of package in dir
+    ImportComment string // path in import comment on package statement
+    Name          string // package name
+    Doc           string // package documentation string
+    Target        string // install path
+    Shlib         string // the shared library that contains this package (only set when -linkshared)
+    Goroot        bool   // is this package in the Go root?
+    Standard      bool   // is this package part of the standard Go library?
+    Stale         bool   // would 'go install' do anything for this package?
+    StaleReason   string // explanation for Stale==true
+    Root          string // Go root or Go path dir containing this package
+    ConflictDir   string // this directory shadows Dir in $GOPATH
+    BinaryOnly    bool   // binary-only package: cannot be recompiled from sources
+
+    // Source files
+    GoFiles        []string // .go source files (excluding CgoFiles, TestGoFiles, XTestGoFiles)
+    CgoFiles       []string // .go sources files that import "C"
+    IgnoredGoFiles []string // .go sources ignored due to build constraints
+    CFiles         []string // .c source files
+    CXXFiles       []string // .cc, .cxx and .cpp source files
+    MFiles         []string // .m source files
+    HFiles         []string // .h, .hh, .hpp and .hxx source files
+    FFiles         []string // .f, .F, .for and .f90 Fortran source files
+    SFiles         []string // .s source files
+    SwigFiles      []string // .swig files
+    SwigCXXFiles   []string // .swigcxx files
+    SysoFiles      []string // .syso object files to add to archive
+    TestGoFiles    []string // _test.go files in package
+    XTestGoFiles   []string // _test.go files outside package
+
+    // Cgo directives
+    CgoCFLAGS    []string // cgo: flags for C compiler
+    CgoCPPFLAGS  []string // cgo: flags for C preprocessor
+    CgoCXXFLAGS  []string // cgo: flags for C++ compiler
+    CgoFFLAGS    []string // cgo: flags for Fortran compiler
+    CgoLDFLAGS   []string // cgo: flags for linker
+    CgoPkgConfig []string // cgo: pkg-config names
+
+    // Dependency information
+    Imports      []string // import paths used by this package
+    Deps         []string // all (recursively) imported dependencies
+    TestImports  []string // imports from TestGoFiles
+    XTestImports []string // imports from XTestGoFiles
+
+    // Error information
+    Incomplete bool            // this package or a dependency has an error
+    Error      *PackageError   // error loading package
+    DepsErrors []*PackageError // errors loading dependencies
+}
+
    +

    +Packages stored in vendor directories report an ImportPath that includes the +path to the vendor directory (for example, "d/vendor/p" instead of "p"), +so that the ImportPath uniquely identifies a given copy of a package. +The Imports, Deps, TestImports, and XTestImports lists also contain these +expanded imports paths. See golang.org/s/go15vendor for more about vendoring. +

    +

    +The error information, if any, is +

    +
    type PackageError struct {
+    ImportStack   []string // shortest path from package named on command line to this one
+    Pos           string   // position of error (if present, file:line:col)
+    Err           string   // the error itself
+}
+
    +

    +The template function "join" calls strings.Join. +

    +

    +The template function "context" returns the build context, defined as: +

    +
    type Context struct {
+	GOARCH        string   // target architecture
+	GOOS          string   // target operating system
+	GOROOT        string   // Go root
+	GOPATH        string   // Go path
+	CgoEnabled    bool     // whether cgo can be used
+	UseAllFiles   bool     // use files regardless of +build lines, file names
+	Compiler      string   // compiler to assume when computing target paths
+	BuildTags     []string // build constraints to match in +build lines
+	ReleaseTags   []string // releases the current release is compatible with
+	InstallSuffix string   // suffix to use in the name of the install dir
+}
+
    +

    +For more information about the meaning of these fields see the documentation +for the go/build package's Context type. +

    +

    +The -json flag causes the package data to be printed in JSON format +instead of using the template format. +

    +

    +The -e flag changes the handling of erroneous packages, those that +cannot be found or are malformed. By default, the list command +prints an error to standard error for each erroneous package and +omits the packages from consideration during the usual printing. +With the -e flag, the list command never prints errors to standard +error and instead processes the erroneous packages with the usual +printing. Erroneous packages will have a non-empty ImportPath and +a non-nil Error field; other information may or may not be missing +(zeroed). +

    +

    +

    Compile and run Go program

    +

    +Usage: +

    +
    go run [build flags] [-exec xprog] gofiles... [arguments...]
+
    +

    +Run compiles and runs the main package comprising the named Go source files. +A Go source file is defined to be a file ending in a literal ".go" suffix. +

    +

    +By default, 'go run' runs the compiled binary directly: 'a.out arguments...'. +If the -exec flag is given, 'go run' invokes the binary using xprog: +

    +
    'xprog a.out arguments...'.
+
    +

    +If the -exec flag is not given, GOOS or GOARCH is different from the system +default, and a program named go_$GOOS_$GOARCH_exec can be found +on the current search path, 'go run' invokes the binary using that program, +for example 'go_nacl_386_exec a.out arguments...'. This allows execution of +cross-compiled programs when a simulator or other execution method is +available. +

    +

    +For more about build flags, see 'go help build'. +

    +

    +See also: go build. +

    +

    Test packages

    +

    +Usage: +

    +
    go test [build/test flags] [packages] [build/test flags & test binary flags]
+
    +

    +'Go test' automates testing the packages named by the import paths. +It prints a summary of the test results in the format: +

    +
    ok   archive/tar   0.011s
+FAIL archive/zip   0.022s
+ok   compress/gzip 0.033s
+...
+
    +

    +followed by detailed output for each failed package. +

    +

    +'Go test' recompiles each package along with any files with names matching +the file pattern "*_test.go". +Files whose names begin with "_" (including "_test.go") or "." are ignored. +These additional files can contain test functions, benchmark functions, and +example functions. See 'go help testfunc' for more. +Each listed package causes the execution of a separate test binary. +

    +

    +Test files that declare a package with the suffix "_test" will be compiled as a +separate package, and then linked and run with the main test binary. +

    +

    +The go tool will ignore a directory named "testdata", making it available +to hold ancillary data needed by the tests. +

    +

    +By default, go test needs no arguments. It compiles and tests the package +with source in the current directory, including tests, and runs the tests. +

    +

    +The package is built in a temporary directory so it does not interfere with the +non-test installation. +

    +

    +In addition to the build flags, the flags handled by 'go test' itself are: +

    +
    -args
+    Pass the remainder of the command line (everything after -args)
+    to the test binary, uninterpreted and unchanged.
+    Because this flag consumes the remainder of the command line,
+    the package list (if present) must appear before this flag.
+
+-c
+    Compile the test binary to pkg.test but do not run it
+    (where pkg is the last element of the package's import path).
+    The file name can be changed with the -o flag.
+
+-exec xprog
+    Run the test binary using xprog. The behavior is the same as
+    in 'go run'. See 'go help run' for details.
+
+-i
+    Install packages that are dependencies of the test.
+    Do not run the test.
+
+-o file
+    Compile the test binary to the named file.
+    The test still runs (unless -c or -i is specified).
+
    +

    +The test binary also accepts flags that control execution of the test; these +flags are also accessible by 'go test'. See 'go help testflag' for details. +

    +

    +For more about build flags, see 'go help build'. +For more about specifying packages, see 'go help packages'. +

    +

    +See also: go build, go vet. +

    +

    Run specified go tool

    +

    +Usage: +

    +
    go tool [-n] command [args...]
+
    +

    +Tool runs the go tool command identified by the arguments. +With no arguments it prints the list of known tools. +

    +

    +The -n flag causes tool to print the command that would be +executed but not execute it. +

    +

    +For more about each tool command, see 'go tool command -h'. +

    +

    Print Go version

    +

    +Usage: +

    +
    go version
+
    +

    +Version prints the Go version, as reported by runtime.Version. +

    +

    Run go tool vet on packages

    +

    +Usage: +

    +
    go vet [-n] [-x] [build flags] [packages]
+
    +

    +Vet runs the Go vet command on the packages named by the import paths. +

    +

    +For more about vet, see 'go doc cmd/vet'. +For more about specifying packages, see 'go help packages'. +

    +

    +To run the vet tool with specific options, run 'go tool vet'. +

    +

    +The -n flag prints commands that would be executed. +The -x flag prints commands as they are executed. +

    +

    +For more about build flags, see 'go help build'. +

    +

    Calling between Go and C

    +

    +There are two different ways to call between Go and C/C++ code. +

    +

    +The first is the cgo tool, which is part of the Go distribution. For +information on how to use it see the cgo documentation (go doc cmd/cgo). +

    +

    +The second is the SWIG program, which is a general tool for +interfacing between languages. For information on SWIG see +http://swig.org/. When running go build, any file with a .swig +extension will be passed to SWIG. Any file with a .swigcxx extension +will be passed to SWIG with the -c++ option. +

    +

    +When either cgo or SWIG is used, go build will pass any .c, .m, .s, +or .S files to the C compiler, and any .cc, .cpp, .cxx files to the C++ +compiler. The CC or CXX environment variables may be set to determine +the C or C++ compiler, respectively, to use. +

    +

    Description of build modes

    +

    +The 'go build' and 'go install' commands take a -buildmode argument which +indicates which kind of object file is to be built. Currently supported values +are: +

    +
    -buildmode=archive
+	Build the listed non-main packages into .a files. Packages named
+	main are ignored.
+
+-buildmode=c-archive
+	Build the listed main package, plus all packages it imports,
+	into a C archive file. The only callable symbols will be those
+	functions exported using a cgo //export comment. Requires
+	exactly one main package to be listed.
+
+-buildmode=c-shared
+	Build the listed main packages, plus all packages that they
+	import, into C shared libraries. The only callable symbols will
+	be those functions exported using a cgo //export comment.
+	Non-main packages are ignored.
+
+-buildmode=default
+	Listed main packages are built into executables and listed
+	non-main packages are built into .a files (the default
+	behavior).
+
+-buildmode=shared
+	Combine all the listed non-main packages into a single shared
+	library that will be used when building with the -linkshared
+	option. Packages named main are ignored.
+
+-buildmode=exe
+	Build the listed main packages and everything they import into
+	executables. Packages not named main are ignored.
+
+-buildmode=pie
+	Build the listed main packages and everything they import into
+	position independent executables (PIE). Packages not named
+	main are ignored.
+
+-buildmode=plugin
+	Build the listed main packages, plus all packages that they
+	import, into a Go plugin. Packages not named main are ignored.
+
    +

    File types

    +

    +The go command examines the contents of a restricted set of files +in each directory. It identifies which files to examine based on +the extension of the file name. These extensions are: +

    +
    .go
+	Go source files.
+.c, .h
+	C source files.
+	If the package uses cgo or SWIG, these will be compiled with the
+	OS-native compiler (typically gcc); otherwise they will
+	trigger an error.
+.cc, .cpp, .cxx, .hh, .hpp, .hxx
+	C++ source files. Only useful with cgo or SWIG, and always
+	compiled with the OS-native compiler.
+.m
+	Objective-C source files. Only useful with cgo, and always
+	compiled with the OS-native compiler.
+.s, .S
+	Assembler source files.
+	If the package uses cgo or SWIG, these will be assembled with the
+	OS-native assembler (typically gcc (sic)); otherwise they
+	will be assembled with the Go assembler.
+.swig, .swigcxx
+	SWIG definition files.
+.syso
+	System object files.
+
    +

    +Files of each of these types except .syso may contain build +constraints, but the go command stops scanning for build constraints +at the first item in the file that is not a blank line or //-style +line comment. See the go/build package documentation for +more details. +

    +

    +Non-test Go source files can also include a //go:binary-only-package +comment, indicating that the package sources are included +for documentation only and must not be used to build the +package binary. This enables distribution of Go packages in +their compiled form alone. See the go/build package documentation +for more details. +

    +

    GOPATH environment variable

    +

    +The Go path is used to resolve import statements. +It is implemented by and documented in the go/build package. +

    +

    +The GOPATH environment variable lists places to look for Go code. +On Unix, the value is a colon-separated string. +On Windows, the value is a semicolon-separated string. +On Plan 9, the value is a list. +

    +

    +If the environment variable is unset, GOPATH defaults +to a subdirectory named "go" in the user's home directory +($HOME/go on Unix, %USERPROFILE%\go on Windows), +unless that directory holds a Go distribution. +Run "go env GOPATH" to see the current GOPATH. +

    +

    +See https://golang.org/wiki/SettingGOPATH to set a custom GOPATH. +

    +

    +Each directory listed in GOPATH must have a prescribed structure: +

    +

    +The src directory holds source code. The path below src +determines the import path or executable name. +

    +

    +The pkg directory holds installed package objects. +As in the Go tree, each target operating system and +architecture pair has its own subdirectory of pkg +(pkg/GOOS_GOARCH). +

    +

    +If DIR is a directory listed in the GOPATH, a package with +source in DIR/src/foo/bar can be imported as "foo/bar" and +has its compiled form installed to "DIR/pkg/GOOS_GOARCH/foo/bar.a". +

    +

    +The bin directory holds compiled commands. +Each command is named for its source directory, but only +the final element, not the entire path. That is, the +command with source in DIR/src/foo/quux is installed into +DIR/bin/quux, not DIR/bin/foo/quux. The "foo/" prefix is stripped +so that you can add DIR/bin to your PATH to get at the +installed commands. If the GOBIN environment variable is +set, commands are installed to the directory it names instead +of DIR/bin. GOBIN must be an absolute path. +

    +

    +Here's an example directory layout: +

    +
    GOPATH=/home/user/go
+
+/home/user/go/
+    src/
+        foo/
+            bar/               (go code in package bar)
+                x.go
+            quux/              (go code in package main)
+                y.go
+    bin/
+        quux                   (installed command)
+    pkg/
+        linux_amd64/
+            foo/
+                bar.a          (installed package object)
+
    +

    +Go searches each directory listed in GOPATH to find source code, +but new packages are always downloaded into the first directory +in the list. +

    +

    +See https://golang.org/doc/code.html for an example. +

    +

    Internal Directories

    +

    +Code in or below a directory named "internal" is importable only +by code in the directory tree rooted at the parent of "internal". +Here's an extended version of the directory layout above: +

    +
    /home/user/go/
+    src/
+        crash/
+            bang/              (go code in package bang)
+                b.go
+        foo/                   (go code in package foo)
+            f.go
+            bar/               (go code in package bar)
+                x.go
+            internal/
+                baz/           (go code in package baz)
+                    z.go
+            quux/              (go code in package main)
+                y.go
+
    +

    +The code in z.go is imported as "foo/internal/baz", but that +import statement can only appear in source files in the subtree +rooted at foo. The source files foo/f.go, foo/bar/x.go, and +foo/quux/y.go can all import "foo/internal/baz", but the source file +crash/bang/b.go cannot. +

    +

    +See https://golang.org/s/go14internal for details. +

    +

    Vendor Directories

    +

    +Go 1.6 includes support for using local copies of external dependencies +to satisfy imports of those dependencies, often referred to as vendoring. +

    +

    +Code below a directory named "vendor" is importable only +by code in the directory tree rooted at the parent of "vendor", +and only using an import path that omits the prefix up to and +including the vendor element. +

    +

    +Here's the example from the previous section, +but with the "internal" directory renamed to "vendor" +and a new foo/vendor/crash/bang directory added: +

    +
    /home/user/go/
+    src/
+        crash/
+            bang/              (go code in package bang)
+                b.go
+        foo/                   (go code in package foo)
+            f.go
+            bar/               (go code in package bar)
+                x.go
+            vendor/
+                crash/
+                    bang/      (go code in package bang)
+                        b.go
+                baz/           (go code in package baz)
+                    z.go
+            quux/              (go code in package main)
+                y.go
+
    +

    +The same visibility rules apply as for internal, but the code +in z.go is imported as "baz", not as "foo/vendor/baz". +

    +

    +Code in vendor directories deeper in the source tree shadows +code in higher directories. Within the subtree rooted at foo, an import +of "crash/bang" resolves to "foo/vendor/crash/bang", not the +top-level "crash/bang". +

    +

    +Code in vendor directories is not subject to import path +checking (see 'go help importpath'). +

    +

    +When 'go get' checks out or updates a git repository, it now also +updates submodules. +

    +

    +Vendor directories do not affect the placement of new repositories +being checked out for the first time by 'go get': those are always +placed in the main GOPATH, never in a vendor subtree. +

    +

    +See https://golang.org/s/go15vendor for details. +

    +

    Environment variables

    +

    +The go command, and the tools it invokes, examine a few different +environment variables. For many of these, you can see the default +value of on your system by running 'go env NAME', where NAME is the +name of the variable. +

    +

    +General-purpose environment variables: +

    +
    GCCGO
+	The gccgo command to run for 'go build -compiler=gccgo'.
+GOARCH
+	The architecture, or processor, for which to compile code.
+	Examples are amd64, 386, arm, ppc64.
+GOBIN
+	The directory where 'go install' will install a command.
+GOOS
+	The operating system for which to compile code.
+	Examples are linux, darwin, windows, netbsd.
+GOPATH
+	For more details see: 'go help gopath'.
+GORACE
+	Options for the race detector.
+	See https://golang.org/doc/articles/race_detector.html.
+GOROOT
+	The root of the go tree.
+
    +

    +Environment variables for use with cgo: +

    +
    CC
+	The command to use to compile C code.
+CGO_ENABLED
+	Whether the cgo command is supported.  Either 0 or 1.
+CGO_CFLAGS
+	Flags that cgo will pass to the compiler when compiling
+	C code.
+CGO_CPPFLAGS
+	Flags that cgo will pass to the compiler when compiling
+	C or C++ code.
+CGO_CXXFLAGS
+	Flags that cgo will pass to the compiler when compiling
+	C++ code.
+CGO_FFLAGS
+	Flags that cgo will pass to the compiler when compiling
+	Fortran code.
+CGO_LDFLAGS
+	Flags that cgo will pass to the compiler when linking.
+CXX
+	The command to use to compile C++ code.
+PKG_CONFIG
+	Path to pkg-config tool.
+
    +

    +Architecture-specific environment variables: +

    +
    GOARM
+	For GOARCH=arm, the ARM architecture for which to compile.
+	Valid values are 5, 6, 7.
+GO386
+	For GOARCH=386, the floating point instruction set.
+	Valid values are 387, sse2.
+
    +

    +Special-purpose environment variables: +

    +
    GOROOT_FINAL
+	The root of the installed Go tree, when it is
+	installed in a location other than where it is built.
+	File names in stack traces are rewritten from GOROOT to
+	GOROOT_FINAL.
+GO_EXTLINK_ENABLED
+	Whether the linker should use external linking mode
+	when using -linkmode=auto with code that uses cgo.
+	Set to 0 to disable external linking mode, 1 to enable it.
+GIT_ALLOW_PROTOCOL
+	Defined by Git. A colon-separated list of schemes that are allowed to be used
+	with git fetch/clone. If set, any scheme not explicitly mentioned will be
+	considered insecure by 'go get'.
+
    +

    Import path syntax

    +

    +An import path (see 'go help packages') denotes a package stored in the local +file system. In general, an import path denotes either a standard package (such +as "unicode/utf8") or a package found in one of the work spaces (For more +details see: 'go help gopath'). +

    +

    Relative import paths

    +

    +An import path beginning with ./ or ../ is called a relative path. +The toolchain supports relative import paths as a shortcut in two ways. +

    +

    +First, a relative path can be used as a shorthand on the command line. +If you are working in the directory containing the code imported as +"unicode" and want to run the tests for "unicode/utf8", you can type +"go test ./utf8" instead of needing to specify the full path. +Similarly, in the reverse situation, "go test .." will test "unicode" from +the "unicode/utf8" directory. Relative patterns are also allowed, like +"go test ./..." to test all subdirectories. See 'go help packages' for details +on the pattern syntax. +

    +

    +Second, if you are compiling a Go program not in a work space, +you can use a relative path in an import statement in that program +to refer to nearby code also not in a work space. +This makes it easy to experiment with small multipackage programs +outside of the usual work spaces, but such programs cannot be +installed with "go install" (there is no work space in which to install them), +so they are rebuilt from scratch each time they are built. +To avoid ambiguity, Go programs cannot use relative import paths +within a work space. +

    +

    Remote import paths

    +

    +Certain import paths also +describe how to obtain the source code for the package using +a revision control system. +

    +

    +A few common code hosting sites have special syntax: +

    +
    Bitbucket (Git, Mercurial)
+
+	import "bitbucket.org/user/project"
+	import "bitbucket.org/user/project/sub/directory"
+
+GitHub (Git)
+
+	import "github.com/user/project"
+	import "github.com/user/project/sub/directory"
+
+Launchpad (Bazaar)
+
+	import "launchpad.net/project"
+	import "launchpad.net/project/series"
+	import "launchpad.net/project/series/sub/directory"
+
+	import "launchpad.net/~user/project/branch"
+	import "launchpad.net/~user/project/branch/sub/directory"
+
+IBM DevOps Services (Git)
+
+	import "hub.jazz.net/git/user/project"
+	import "hub.jazz.net/git/user/project/sub/directory"
+
    +

    +For code hosted on other servers, import paths may either be qualified +with the version control type, or the go tool can dynamically fetch +the import path over https/http and discover where the code resides +from a <meta> tag in the HTML. +

    +

    +To declare the code location, an import path of the form +

    +
    repository.vcs/path
+
    +

    +specifies the given repository, with or without the .vcs suffix, +using the named version control system, and then the path inside +that repository. The supported version control systems are: +

    +
    Bazaar      .bzr
+Git         .git
+Mercurial   .hg
+Subversion  .svn
+
    +

    +For example, +

    +
    import "example.org/user/foo.hg"
+
    +

    +denotes the root directory of the Mercurial repository at +example.org/user/foo or foo.hg, and +

    +
    import "example.org/repo.git/foo/bar"
+
    +

    +denotes the foo/bar directory of the Git repository at +example.org/repo or repo.git. +

    +

    +When a version control system supports multiple protocols, +each is tried in turn when downloading. For example, a Git +download tries https://, then git+ssh://. +

    +

    +By default, downloads are restricted to known secure protocols +(e.g. https, ssh). To override this setting for Git downloads, the +GIT_ALLOW_PROTOCOL environment variable can be set (For more details see: +'go help environment'). +

    +

    +If the import path is not a known code hosting site and also lacks a +version control qualifier, the go tool attempts to fetch the import +over https/http and looks for a <meta> tag in the document's HTML +<head>. +

    +

    +The meta tag has the form: +

    +
    <meta name="go-import" content="import-prefix vcs repo-root">
+
    +

    +The import-prefix is the import path corresponding to the repository +root. It must be a prefix or an exact match of the package being +fetched with "go get". If it's not an exact match, another http +request is made at the prefix to verify the <meta> tags match. +

    +

    +The meta tag should appear as early in the file as possible. +In particular, it should appear before any raw JavaScript or CSS, +to avoid confusing the go command's restricted parser. +

    +

    +The vcs is one of "git", "hg", "svn", etc, +

    +

    +The repo-root is the root of the version control system +containing a scheme and not containing a .vcs qualifier. +

    +

    +For example, +

    +
    import "example.org/pkg/foo"
+
    +

    +will result in the following requests: +

    +
    https://example.org/pkg/foo?go-get=1 (preferred)
+http://example.org/pkg/foo?go-get=1  (fallback, only with -insecure)
+
    +

    +If that page contains the meta tag +

    +
    <meta name="go-import" content="example.org git https://code.org/r/p/exproj">
+
    +

    +the go tool will verify that https://example.org/?go-get=1 contains the +same meta tag and then git clone https://code.org/r/p/exproj into +GOPATH/src/example.org. +

    +

    +New downloaded packages are written to the first directory listed in the GOPATH +environment variable (For more details see: 'go help gopath'). +

    +

    +The go command attempts to download the version of the +package appropriate for the Go release being used. +Run 'go help get' for more. +

    +

    Import path checking

    +

    +When the custom import path feature described above redirects to a +known code hosting site, each of the resulting packages has two possible +import paths, using the custom domain or the known hosting site. +

    +

    +A package statement is said to have an "import comment" if it is immediately +followed (before the next newline) by a comment of one of these two forms: +

    +
    package math // import "path"
+package math /* import "path" */
+
    +

    +The go command will refuse to install a package with an import comment +unless it is being referred to by that import path. In this way, import comments +let package authors make sure the custom import path is used and not a +direct path to the underlying code hosting site. +

    +

    +Import path checking is disabled for code found within vendor trees. +This makes it possible to copy code into alternate locations in vendor trees +without needing to update import comments. +

    +

    +See https://golang.org/s/go14customimport for details. +

    +

    Description of package lists

    +

    +Many commands apply to a set of packages: +

    +
    go action [packages]
+
    +

    +Usually, [packages] is a list of import paths. +

    +

    +An import path that is a rooted path or that begins with +a . or .. element is interpreted as a file system path and +denotes the package in that directory. +

    +

    +Otherwise, the import path P denotes the package found in +the directory DIR/src/P for some DIR listed in the GOPATH +environment variable (For more details see: 'go help gopath'). +

    +

    +If no import paths are given, the action applies to the +package in the current directory. +

    +

    +There are four reserved names for paths that should not be used +for packages to be built with the go tool: +

    +

    +- "main" denotes the top-level package in a stand-alone executable. +

    +

    +- "all" expands to all package directories found in all the GOPATH +trees. For example, 'go list all' lists all the packages on the local +system. +

    +

    +- "std" is like all but expands to just the packages in the standard +Go library. +

    +

    +- "cmd" expands to the Go repository's commands and their +internal libraries. +

    +

    +Import paths beginning with "cmd/" only match source code in +the Go repository. +

    +

    +An import path is a pattern if it includes one or more "..." wildcards, +each of which can match any string, including the empty string and +strings containing slashes. Such a pattern expands to all package +directories found in the GOPATH trees with names matching the +patterns. As a special case, x/... matches x as well as x's subdirectories. +For example, net/... expands to net and packages in its subdirectories. +

    +

    +An import path can also name a package to be downloaded from +a remote repository. Run 'go help importpath' for details. +

    +

    +Every package in a program must have a unique import path. +By convention, this is arranged by starting each path with a +unique prefix that belongs to you. For example, paths used +internally at Google all begin with 'google', and paths +denoting remote repositories begin with the path to the code, +such as 'github.com/user/repo'. +

    +

    +Packages in a program need not have unique package names, +but there are two reserved package names with special meaning. +The name main indicates a command, not a library. +Commands are built into binaries and cannot be imported. +The name documentation indicates documentation for +a non-Go program in the directory. Files in package documentation +are ignored by the go command. +

    +

    +As a special case, if the package list is a list of .go files from a +single directory, the command is applied to a single synthesized +package made up of exactly those files, ignoring any build constraints +in those files and ignoring any other files in the directory. +

    +

    +Directory and file names that begin with "." or "_" are ignored +by the go tool, as are directories named "testdata". +

    +

    Description of testing flags

    +

    +The 'go test' command takes both flags that apply to 'go test' itself +and flags that apply to the resulting test binary. +

    +

    +Several of the flags control profiling and write an execution profile +suitable for "go tool pprof"; run "go tool pprof -h" for more +information. The --alloc_space, --alloc_objects, and --show_bytes +options of pprof control how the information is presented. +

    +

    +The following flags are recognized by the 'go test' command and +control the execution of any test: +

    +
    -bench regexp
+    Run (sub)benchmarks matching a regular expression.
+    The given regular expression is split into smaller ones by
+    top-level '/', where each must match the corresponding part of a
+    benchmark's identifier.
+    By default, no benchmarks run. To run all benchmarks,
+    use '-bench .' or '-bench=.'.
+
+-benchtime t
+    Run enough iterations of each benchmark to take t, specified
+    as a time.Duration (for example, -benchtime 1h30s).
+    The default is 1 second (1s).
+
+-count n
+    Run each test and benchmark n times (default 1).
+    If -cpu is set, run n times for each GOMAXPROCS value.
+    Examples are always run once.
+
+-cover
+    Enable coverage analysis.
+
+-covermode set,count,atomic
+    Set the mode for coverage analysis for the package[s]
+    being tested. The default is "set" unless -race is enabled,
+    in which case it is "atomic".
+    The values:
+	set: bool: does this statement run?
+	count: int: how many times does this statement run?
+	atomic: int: count, but correct in multithreaded tests;
+		significantly more expensive.
+    Sets -cover.
+
+-coverpkg pkg1,pkg2,pkg3
+    Apply coverage analysis in each test to the given list of packages.
+    The default is for each test to analyze only the package being tested.
+    Packages are specified as import paths.
+    Sets -cover.
+
+-cpu 1,2,4
+    Specify a list of GOMAXPROCS values for which the tests or
+    benchmarks should be executed.  The default is the current value
+    of GOMAXPROCS.
+
+-parallel n
+    Allow parallel execution of test functions that call t.Parallel.
+    The value of this flag is the maximum number of tests to run
+    simultaneously; by default, it is set to the value of GOMAXPROCS.
+    Note that -parallel only applies within a single test binary.
+    The 'go test' command may run tests for different packages
+    in parallel as well, according to the setting of the -p flag
+    (see 'go help build').
+
+-run regexp
+    Run only those tests and examples matching the regular expression.
+    For tests the regular expression is split into smaller ones by
+    top-level '/', where each must match the corresponding part of a
+    test's identifier.
+
+-short
+    Tell long-running tests to shorten their run time.
+    It is off by default but set during all.bash so that installing
+    the Go tree can run a sanity check but not spend time running
+    exhaustive tests.
+
+-timeout t
+    If a test runs longer than t, panic.
+    The default is 10 minutes (10m).
+
+-v
+    Verbose output: log all tests as they are run. Also print all
+    text from Log and Logf calls even if the test succeeds.
+
    +

    +The following flags are also recognized by 'go test' and can be used to +profile the tests during execution: +

    +
    -benchmem
+    Print memory allocation statistics for benchmarks.
+
+-blockprofile block.out
+    Write a goroutine blocking profile to the specified file
+    when all tests are complete.
+    Writes test binary as -c would.
+
+-blockprofilerate n
+    Control the detail provided in goroutine blocking profiles by
+    calling runtime.SetBlockProfileRate with n.
+    See 'go doc runtime.SetBlockProfileRate'.
+    The profiler aims to sample, on average, one blocking event every
+    n nanoseconds the program spends blocked.  By default,
+    if -test.blockprofile is set without this flag, all blocking events
+    are recorded, equivalent to -test.blockprofilerate=1.
+
+-coverprofile cover.out
+    Write a coverage profile to the file after all tests have passed.
+    Sets -cover.
+
+-cpuprofile cpu.out
+    Write a CPU profile to the specified file before exiting.
+    Writes test binary as -c would.
+
+-memprofile mem.out
+    Write a memory profile to the file after all tests have passed.
+    Writes test binary as -c would.
+
+-memprofilerate n
+    Enable more precise (and expensive) memory profiles by setting
+    runtime.MemProfileRate.  See 'go doc runtime.MemProfileRate'.
+    To profile all memory allocations, use -test.memprofilerate=1
+    and pass --alloc_space flag to the pprof tool.
+
+-mutexprofile mutex.out
+    Write a mutex contention profile to the specified file
+    when all tests are complete.
+    Writes test binary as -c would.
+
+-mutexprofilefraction n
+    Sample 1 in n stack traces of goroutines holding a
+    contended mutex.
+
+-outputdir directory
+    Place output files from profiling in the specified directory,
+    by default the directory in which "go test" is running.
+
+-trace trace.out
+    Write an execution trace to the specified file before exiting.
+
    +

    +Each of these flags is also recognized with an optional 'test.' prefix, +as in -test.v. When invoking the generated test binary (the result of +'go test -c') directly, however, the prefix is mandatory. +

    +

    +The 'go test' command rewrites or removes recognized flags, +as appropriate, both before and after the optional package list, +before invoking the test binary. +

    +

    +For instance, the command +

    +
    go test -v -myflag testdata -cpuprofile=prof.out -x
+
    +

    +will compile the test binary and then run it as +

    +
    pkg.test -test.v -myflag testdata -test.cpuprofile=prof.out
+
    +

    +(The -x flag is removed because it applies only to the go command's +execution, not to the test itself.) +

    +

    +The test flags that generate profiles (other than for coverage) also +leave the test binary in pkg.test for use when analyzing the profiles. +

    +

    +When 'go test' runs a test binary, it does so from within the +corresponding package's source code directory. Depending on the test, +it may be necessary to do the same when invoking a generated test +binary directly. +

    +

    +The command-line package list, if present, must appear before any +flag not known to the go test command. Continuing the example above, +the package list would have to appear before -myflag, but could appear +on either side of -v. +

    +

    +To keep an argument for a test binary from being interpreted as a +known flag or a package name, use -args (see 'go help test') which +passes the remainder of the command line through to the test binary +uninterpreted and unaltered. +

    +

    +For instance, the command +

    +
    go test -v -args -x -v
+
    +

    +will compile the test binary and then run it as +

    +
    pkg.test -test.v -x -v
+
    +

    +Similarly, +

    +
    go test -args math
+
    +

    +will compile the test binary and then run it as +

    +
    pkg.test math
+
    +

    +In the first example, the -x and the second -v are passed through to the +test binary unchanged and with no effect on the go command itself. +In the second example, the argument math is passed through to the test +binary, instead of being interpreted as the package list. +

    +

    Description of testing functions

    +

    +The 'go test' command expects to find test, benchmark, and example functions +in the "*_test.go" files corresponding to the package under test. +

    +

    +A test function is one named TestXXX (where XXX is any alphanumeric string +not starting with a lower case letter) and should have the signature, +

    +
    func TestXXX(t *testing.T) { ... }
+
    +

    +A benchmark function is one named BenchmarkXXX and should have the signature, +

    +
    func BenchmarkXXX(b *testing.B) { ... }
+
    +

    +An example function is similar to a test function but, instead of using +*testing.T to report success or failure, prints output to os.Stdout. +If the last comment in the function starts with "Output:" then the output +is compared exactly against the comment (see examples below). If the last +comment begins with "Unordered output:" then the output is compared to the +comment, however the order of the lines is ignored. An example with no such +comment is compiled but not executed. An example with no text after +"Output:" is compiled, executed, and expected to produce no output. +

    +

    +Godoc displays the body of ExampleXXX to demonstrate the use +of the function, constant, or variable XXX. An example of a method M with +receiver type T or *T is named ExampleT_M. There may be multiple examples +for a given function, constant, or variable, distinguished by a trailing _xxx, +where xxx is a suffix not beginning with an upper case letter. +

    +

    +Here is an example of an example: +

    +
    func ExamplePrintln() {
+	Println("The output of\nthis example.")
+	// Output: The output of
+	// this example.
+}
+
    +

    +Here is another example where the ordering of the output is ignored: +

    +
    func ExamplePerm() {
+	for _, value := range Perm(4) {
+		fmt.Println(value)
+	}
+
+	// Unordered output: 4
+	// 2
+	// 1
+	// 3
+	// 0
+}
+
    +

    +The entire test file is presented as the example when it contains a single +example function, at least one other function, type, variable, or constant +declaration, and no test or benchmark functions. +

    +

    +See the documentation of the testing package for more information. +

When the `Status` message is +// exposed in different client libraries and different wire protocols, it can be +// mapped differently.

A typical workflow has multiple steps. Each step may +// have a `Status` message for error reporting purpose. +// +// - Batch operations. If a client uses batch request and batch response, the +// `Status` message should be used directly inside batch response, one for +// each error sub-response. +// +// - Asynchronous operations. If an API call embeds asynchronous operation +// results in its response, the status of those operations should be +// represented directly using the `Status` message. +// +// - Logging. If some API errors are stored in logs, the message `Status` could +// be used directly after any stripping needed for security/privacy reasons. +type Status struct { + // The status code, which should be an enum value of [google.rpc.Code][google.rpc.Code]. + Code int32 `protobuf:"varint,1,opt,name=code" json:"code,omitempty"` + // A developer-facing error message, which should be in English.
