func FoldDup ¶
func FoldDup(list []string) (string, string)
FoldDup reports a pair of strings from the list that are equal according to strings.EqualFold. It returns "", "" if there are no such strings.
func HasFilePathPrefix ¶
func HasFilePathPrefix(s, prefix string) bool
HasFilePathPrefix reports whether the filesystem path s begins with the elements in prefix.
HasFilePathPrefix is case-sensitive (except for volume names) even if the filesystem is not, does not apply Unicode normalization even if the filesystem does, and assumes that all path separators are canonicalized to filepath.Separator (as returned by filepath.Clean).
func HasPathPrefix ¶
func HasPathPrefix(s, prefix string) bool
HasPathPrefix reports whether the slash-separated path s begins with the elements in prefix.
func QuoteGlob ¶
func QuoteGlob(s string) string
QuoteGlob returns s with all Glob metacharacters quoted. We don't try to handle backslash here, as that can appear in a file path on Windows.
func StringList ¶
func StringList(args ...any) []string
StringList flattens its arguments into a single []string. Each argument in args must have type string or []string.
func ToFold ¶
func ToFold(s string) string
ToFold returns a string with the property that
strings.EqualFold(s, t) iff ToFold(s) == ToFold(t)
This lets us test a large set of strings for fold-equivalent duplicates without making a quadratic number of calls to EqualFold. Note that strings.ToUpper and strings.ToLower do not have the desired property in some corner cases.
func TrimFilePathPrefix ¶
func TrimFilePathPrefix(s, prefix string) string
TrimFilePathPrefix returns s without the leading path elements in prefix, such that joining the string to prefix produces s.
If s does not start with prefix (HasFilePathPrefix with the same arguments returns false), TrimFilePathPrefix returns s. If s equals prefix, TrimFilePathPrefix returns "".
func Uniq ¶
func Uniq(ss *[]string)
Uniq removes consecutive duplicate strings from ss.
func WithFilePathSeparator ¶
func WithFilePathSeparator(s string) string
WithFilePathSeparator returns s with a trailing path separator, or the empty string if s is empty.
