Example:
PACKAGE
package utf8
import "unicode/utf8"
Package utf8 implements functions and constants to support text
encoded in UTF-8. This package calls a Unicode character a rune for
brevity.
CONSTANTS
const (
RuneError = unicode.ReplacementChar // the "error" Rune or "replacement character".
RuneSelf = 0x80 // characters below Runeself are represented as themselves in a single byte.
UTFMax = 4 // maximum number of bytes of a UTF-8 encoded Unicode character.
)
Numbers fundamental to the encoding.
FUNCTIONS
func DecodeLastRune(p []byte) (r rune, size int)
DecodeLastRune unpacks the last UTF-8 encoding in p and returns the
rune and its width in bytes.
func DecodeLastRuneInString(s string) (r rune, size int)
DecodeLastRuneInString is like DecodeLastRune but its input is a
string.
func DecodeRune(p []byte) (r rune, size int)
DecodeRune unpacks the first UTF-8 encoding in p and returns the rune
and its width in bytes.
func DecodeRuneInString(s string) (r rune, size int)
DecodeRuneInString is like DecodeRune but its input is a string.
func EncodeRune(p []byte, r rune) int
EncodeRune writes into p (which must be large enough) the UTF-8
encoding of the rune. It returns the number of bytes written.
func FullRune(p []byte) bool
FullRune reports whether the bytes in p begin with a full UTF-8
encoding of a rune. An invalid encoding is considered a full Rune
since it will convert as a width-1 error rune.
func FullRuneInString(s string) bool
FullRuneInString is like FullRune but its input is a string.
func RuneCount(p []byte) int
RuneCount returns the number of runes in p. Erroneous and short
encodings are treated as single runes of width 1 byte.
func RuneCountInString(s string) (n int)
RuneCountInString is like RuneCount but its input is a string.
func RuneLen(r rune) int
RuneLen returns the number of bytes required to encode the rune.
func RuneStart(b byte) bool
RuneStart reports whether the byte could be the first byte of an
encoded rune. Second and subsequent bytes always have the top two
bits set to 10.
func Valid(p []byte) bool
Valid reports whether p consists entirely of valid UTF-8-encoded
runes.
func ValidString(s string) bool
ValidString reports whether s consists entirely of valid UTF-8-encoded
runes.
TYPES
type String struct {
// contains filtered or unexported fields
}
String wraps a regular string with a small structure that provides
more efficient indexing by code point index, as opposed to byte index.
Scanning incrementally forwards or backwards is O(1) per index
operation (although not as fast a range clause going forwards).
Random access is O(N) in the length of the string, but the overhead is
less than always scanning from the beginning. If the string is ASCII,
random access is O(1). Unlike the built-in string type, String has
internal mutable state and is not thread-safe.
func NewString(contents string) *String
NewString returns a new UTF-8 string with the provided contents.
func (s *String) At(i int) rune
At returns the rune with index i in the String. The sequence of runes
is the same as iterating over the contents with a "for range" clause.
func (s *String) Init(contents string) *String
Init initializes an existing String to hold the provided contents.
It returns a pointer to the initialized String.
func (s *String) IsASCII() bool
IsASCII returns a boolean indicating whether the String contains only
ASCII bytes.
func (s *String) RuneCount() int
RuneCount returns the number of runes (Unicode code points) in the
String.
func (s *String) Slice(i, j int) string
Slice returns the string sliced at rune positions [i:j].
func (s *String) String() string
String returns the contents of the String. This method also means the
String is directly printable by fmt.Print.
Fixes#2479.

This feature should make it easier to look at very large
directory trees.
- a new mode (URL: /pkg/?m=flat) shows directory listings w/o
indentation and entries with full path (html and text mode)
- in text mode, hierarchical (non-flat) directory listings are
now presented with indentation (/pkg/?m=text)
- in html mode, hierarchical (non-flat) directory listings are
presented with slightly less indentation
- there is an internal hook for programmatic control of the
display mode (for specialized versions of godoc).

1. Generate TOC for package pages using template,
instead of using JavaScript magic. This makes the
pages generated by godoc -html easier to export
to other systems.
2. Make TOC one column. It's hard to do two columns
portably without invoking JavaScript.
3. Since the TOC is only one column, show full type
signatures for functions and methods. Many times
that's all you need to see anyway.
4. Name the section after the TOC "Overview".
Naming it something is important, to set it off
from the TOC and so that there's a quick link to
it in the TOC.
For now, some illustrative examples:

This CL introduces the go.Example type and go.Examples functions that
are used to represent and extract code samples from Go source.
They should be of the form:
// Output of this function.
func ExampleFoo() {
fmt.Println("Output of this function.")
}
It also modifies godoc to read example code from _test.go files,
and include them in the HTML output with JavaScript-driven toggles.
It also implements testing of example functions with gotest.
The stdout/stderr is compared against the output comment on the
function.
This CL includes examples for the sort.Ints function and the
sort.SortInts type. After patching this CL in and re-building go/doc
and godoc, try
godoc -http=localhost:6060
and visit http://localhost:6060/pkg/sort/
