Package strings
import "strings"
A package of simple functions to manipulate strings.
Package files
reader.go strings.gofunc Count
func Count(s, sep string) int
Count counts the number of non-overlapping instances of sep in s.
func Fields
func Fields(s string) []string
Fields splits the string s around each instance of one or more consecutive white space characters, returning an array of substrings of s or an empty list if s contains only white space.
func HasPrefix
func HasPrefix(s, prefix string) bool
HasPrefix tests whether the string s begins with prefix.
func HasSuffix
func HasSuffix(s, suffix string) bool
HasSuffix tests whether the string s ends with suffix.
func Index
func Index(s, sep string) int
Index returns the index of the first instance of sep in s, or -1 if sep is not present in s.
func Join
func Join(a []string, sep string) string
Join concatenates the elements of a to create a single string. The separator string sep is placed between elements in the resulting string.
func LastIndex
func LastIndex(s, sep string) int
LastIndex returns the index of the last instance of sep in s, or -1 if sep is not present in s.
func Map
func Map(mapping func(rune int) int, s string) string
Map returns a copy of the string s with all its characters modified according to the mapping function. If mapping returns a negative value, the character is dropped from the string with no replacement.
func Repeat
func Repeat(s string, count int) string
Repeat returns a new string consisting of count copies of the string s.
func Split
func Split(s, sep string, n int) []string
Split splits the string s around each instance of sep, returning an array of substrings of s. If sep is empty, Split splits s after each UTF-8 sequence. If n > 0, Split splits s into at most n substrings; the last substring will be the unsplit remainder.
func SplitAfter
func SplitAfter(s, sep string, n int) []string
SplitAfter splits the string s after each instance of sep, returning an array of substrings of s. If sep is empty, SplitAfter splits s after each UTF-8 sequence. If n > 0, SplitAfter splits s into at most n substrings; the last substring will be the unsplit remainder.
func ToLower
func ToLower(s string) string
ToLower returns a copy of the string s with all Unicode letters mapped to their lower case.
func ToTitle
func ToTitle(s string) string
ToTitle returns a copy of the string s with all Unicode letters mapped to their title case.
func ToUpper
func ToUpper(s string) string
ToUpper returns a copy of the string s with all Unicode letters mapped to their upper case.
func TrimSpace
func TrimSpace(s string) string
Trim returns a slice of the string s, with all leading and trailing white space removed, as defined by Unicode.
type Reader
A Reader satisfies calls to Read and ReadByte by reading from a string.
type Reader string
func NewReader
func NewReader(s string) *Reader
NewReader returns a new Reader reading from s. It is similar to bytes.NewBufferString but more efficient and read-only.
func (*Reader) Read
func (r *Reader) Read(b []byte) (n int, err os.Error)
func (*Reader) ReadByte
func (r *Reader) ReadByte() (b byte, err os.Error)
