func AnyTags Uses

func AnyTags() map[string]bool

AnyTags returns a special set of build tags that satisfy nearly all build tag expressions. Only "ignore" and malformed build tag requirements are considered false.

func MatchFile Uses

func MatchFile(name string, tags map[string]bool) bool

MatchFile returns false if the name contains a $GOOS or $GOARCH suffix which does not match the current system. The recognized name formats are:

name_$(GOOS).*
name_$(GOARCH).*
name_$(GOOS)_$(GOARCH).*
name_$(GOOS)_test.*
name_$(GOARCH)_test.*
name_$(GOOS)_$(GOARCH)_test.*

Exceptions:

if GOOS=android, then files with GOOS=linux are also matched.
if GOOS=illumos, then files with GOOS=solaris are also matched.

If tags["*"] is true, then MatchFile will consider all possible GOOS and GOARCH to be available and will consequently always return true.

func ReadComments Uses

func ReadComments(f io.Reader) ([]byte, error)

ReadComments is like ioutil.ReadAll, except that it only reads the leading block of comments in the file.

func ReadImports Uses

func ReadImports(f io.Reader, reportSyntaxError bool, imports *[]string) ([]byte, error)

ReadImports is like ioutil.ReadAll, except that it expects a Go file as input and stops reading the input once the imports have completed.

func ScanDir Uses

func ScanDir(dir string, tags map[string]bool) ([]string, []string, error)

func ScanFiles Uses

func ScanFiles(files []string, tags map[string]bool) ([]string, []string, error)

func ShouldBuild Uses

func ShouldBuild(content []byte, tags map[string]bool) bool

ShouldBuild reports whether it is okay to use this file, The rule is that in the file's leading run of // comments and blank lines, which must be followed by a blank line (to avoid including a Go package clause doc comment), lines beginning with '// +build' are taken as build directives.

The file is accepted only if each such line lists something matching the file. For example:

// +build windows linux

marks the file as applicable only on Windows and Linux.

If tags["*"] is true, then ShouldBuild will consider every build tag except "ignore" to be both true and false for the purpose of satisfying build tags, in order to estimate (conservatively) whether a file could ever possibly be used in any build.

func Tags Uses

func Tags() map[string]bool

Tags returns a set of build tags that are true for the target platform. It includes GOOS, GOARCH, the compiler, possibly "cgo", release tags like "go1.13", and user-specified build tags.
