Variables

var StdAllCaps = MustNewAllCaps("acl", "api", "ascii", "cpu", "css", "dns",
	"eof", "guid", "html", "http", "https", "id", "ip", "json", "lhs", "qps",
	"ram", "rhs", "rpc", "sla", "smtp", "sql", "ssh", "tcp", "tls", "ttl",
	"udp", "ui", "uid", "uuid", "uri", "url", "utf8", "vm", "xml", "xmpp",
	"xsrf", "xss")

StdAllCaps provides the standard list of words that golint expects to be capitalized, found in the variable 'commonInitialisms' in https://github.com/golang/lint/blob/master/lint.go

Functions

func CollapseSpaces

func CollapseSpaces(in string) string

CollapseSpaces removes leading and trailing spaces and reduces any runs of two or more spaces to a single space.

func DigitToValue

func DigitToValue(ch rune) (int, error)

DigitToValue converts a unicode digit into a numeric value.

func DurationToCode

func DurationToCode(duration time.Duration) string

DurationToCode turns a time.Duration into more human-readable text required for code than a simple number of nanoseconds.

func FirstN

func FirstN(s string, n int) string

FirstN returns the first n runes of a string.

func FirstToLower

func FirstToLower(in string) string

FirstToLower converts the first character to lower case.

func FirstToUpper

func FirstToUpper(in string) string

FirstToUpper converts the first character to upper case.

func FormatDuration

func FormatDuration(duration time.Duration, includeMillis bool) string

FormatDuration formats the duration as either "0:00:00" or "0:00:00.000".

func LastN

func LastN(s string, n int) string

LastN returns the last n runes of a string.

func NaturalLess

func NaturalLess(s1, s2 string, caseInsensitive bool) bool

NaturalLess compares two strings using natural ordering. This means that "a2" < "a12".

Non-digit sequences and numbers are compared separately. The former are compared bytewise, while the latter are compared numerically (except that the number of leading zeros is used as a tie-breaker, so "2" < "02").

Limitations:

• only ASCII digits (0-9) are considered.

Original algorithm:

func ParseDuration

func ParseDuration(duration string) (time.Duration, error)

ParseDuration parses the duration string, as produced by FormatDuration().

func ToCamelCase

func ToCamelCase(in string) string

ToCamelCase converts a string to CamelCase.

func ToCamelCaseWithExceptions

func ToCamelCaseWithExceptions(in string, exceptions *AllCaps) string

ToCamelCaseWithExceptions converts a string to CamelCase, but forces certain words to all caps.

func ToSnakeCase

func ToSnakeCase(in string) string

ToSnakeCase converts a string to snake_case.

Types

type AllCaps

type AllCaps struct {
	// contains filtered or unexported fields
}

AllCaps holds information for transforming text with ToCamelCaseWithExceptions.

func MustNewAllCaps

func MustNewAllCaps(in ...string) *AllCaps

MustNewAllCaps takes a list of words that should be all uppercase when part of a camel-cased string. Failure to create the AllCaps object causes the program to exit.

func NewAllCaps

func NewAllCaps(in ...string) (*AllCaps, error)

NewAllCaps takes a list of words that should be all uppercase when part of a camel-cased string.

type RuneReader

type RuneReader struct {
	Src []rune
	Pos int
}

RuneReader implements io.RuneReader

func (*RuneReader) ReadRune

func (rr *RuneReader) ReadRune() (r rune, size int, err error)

ReadRune returns the next rune and its size in bytes.
