func ExecsInPath ¶

func ExecsInPath(path string, lookalike func(string) bool) ([]string, error)

execsInPath returns a list of executables in the given path. The returned paths are absolute.

The given path should be an absolute path to a directory. If it's not a directory, the function will not proceed and return a nil slice.

lookalike accepts a function that returns true if the file name matches what we are expecting. Example:

func looksLikePip(name string) bool {
	var pipFileRegex = regexp.MustCompile(`^pip3(\d(\.\d\d?)?)?$`)
	return pipFileRegex.MatchString(name)
}

func IsDir ¶

func IsDir(path string) bool

IsDir returns true if the given path exists and is a directory. It delegates to os.Stat and FileInfo.IsDir.

func IsExecutable ¶

func IsExecutable(info fs.FileInfo) bool

IsExecutable returns true if the given file info is executable. On Windows, it just checks if the file extension is ".exe" or not.
