Functions ¶

func Contains ¶

func Contains(x []string, s string) bool

Contains reports whether x contains s.

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 GlobsMatchPath ¶

func GlobsMatchPath(globs, target string) bool

GlobsMatchPath reports whether any path prefix of target matches one of the glob patterns (as defined by path.Match) in the comma-separated globs list. It ignores any empty or malformed patterns in the list.

func HasFilePathPrefix ¶

func HasFilePathPrefix(s, prefix string) bool

HasFilePathPrefix reports whether the filesystem path s begins with the elements in prefix.

func HasPathPrefix ¶

func HasPathPrefix(s, prefix string) bool

HasPathPrefix reports whether the slash-separated path s begins with the elements in prefix.

func SplitQuotedFields ¶

func SplitQuotedFields(s string) ([]string, error)

SplitQuotedFields splits s into a list of fields, allowing single or double quotes around elements. There is no unescaping or other processing within quoted fields.

func StringList ¶

func StringList(args ...interface{}) []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.
