func NewWatcher

func NewWatcher(paths []string, ignore PathMatcher, l logger.Logger) (Notify, error)

type PathMatcher added in v0.9.3

	MatchesEntireDir(file string) (bool, error)
}

When we specify directories to watch, we often want to ignore some subset of the files under those directories.

For example: - Watch /src/repo, but ignore /src/repo/.git - Watch /src/repo, but ignore everything in /src/repo/bazel-bin except /src/repo/bazel-bin/app-binary

The PathMatcher inteface helps us manage these ignores.

	// contains filtered or unexported fields
}

TempDir holds a temp directory and allows easy access to new temp directories.

NewDir creates a new TempDir in the default location (typically $TMPDIR)

func NewDirAtRoot

func NewDirAtRoot(root, prefix string) (*TempDir, error)

NewDir creates a new TempDir at the given root.

func NewDirAtSlashTmp

func NewDirAtSlashTmp(prefix string) (*TempDir, error)

NewDirAtSlashTmp creates a new TempDir at /tmp

func (*TempDir) NewDeterministicDir

func (d *TempDir) NewDeterministicDir(name string) (*TempDir, error)

func (*TempDir) NewDir

func (d *TempDir) NewDir(prefix string) (*TempDir, error)

d.NewDir creates a new TempDir under d

func (*TempDir) Path
