type Environment 

type Environment interface {
	Getenv(string) string
	LookupEnv(string) (string, bool)
}

Environment allows us to mock the OS environment

type GitSemVer 

type GitSemVer struct {
	Git      Gitter      // Git
	Env      Environment // environment
	DebugOut io.Writer   // if nit nil, write debug output here
	// contains filtered or unexported fields
}

func New 

func New(gitBin string) (vs *GitSemVer, err error)

New returns a GitSemVer ready to examine the git repositories using the given Git binary.

func (*GitSemVer) Debug added in v1.3.21 

func (vs *GitSemVer) Debug(f string, args ...any)

Debug writes debugging output to DebugOut if it's not nil.

func (*GitSemVer) GetBranch 

func (vs *GitSemVer) GetBranch(repo string) (branchName string)

GetBranch returns the current branch as a string suitable for inclusion in the semver text as well as the actual branch name in the build system or Git. If no branch name can be found (for example, in detached HEAD state), then an empty string is returned.

func (*GitSemVer) GetBuild 

func (vs *GitSemVer) GetBuild(repo string) (build string)

GetBuild returns the build counter. This is taken from the CI system if available, otherwise the Git commit count is used. Returns an empty string if no reasonable build counter can be found.

func (*GitSemVer) GetTag 

func (vs *GitSemVer) GetTag(repo string) (string, bool)

GetTag returns the semver git version tag matching the current tree, or the closest semver tag if none match exactly. It also returns a bool that is true if the tree hashes match and there are no uncommitted changes.

func (*GitSemVer) GetVersion 

func (vs *GitSemVer) GetVersion(repo string) (vi VersionInfo, err error)

GetVersion returns a VersionInfo for the source code in the Git repository.

func (*GitSemVer) IsEnvTrue 

func (vs *GitSemVer) IsEnvTrue(envvar string) (yes bool)

IsEnvTrue returns true if the given environment variable exists and is set to something that parses as true.

func (*GitSemVer) IsReleaseBranch 

func (vs *GitSemVer) IsReleaseBranch(branchName string) bool

IsReleaseBranch returns true if the given branch name should be allowed to use 'release mode', where the version string doesn't contains build information suffix.

type GitTag added in v1.4.33 

type GitTag struct {
