Functions

func Coalesce

func Coalesce(v ...string) string

Return the first non-empty string from those provided

func CollapseSpaces

func CollapseSpaces(s string) string

*

• Collapse whitespace

func Hexdump

func Hexdump(w io.Writer, b []byte, cols int)

Write a string in the manner of the output of `hexdump -C`, with byte values on the left corresponding to characters on the right, when printable

func IdentizeString

func IdentizeString(s string) string

Identize terms

func Indent

func Indent(s, p string) string

Indent a string by prefixing each line with the provided string

func IndentWithOptions

func IndentWithOptions(s, p string, opt IndentOptions) string

Indent a string by prefixing each line with the provided string

func NewIndentWriter

func NewIndentWriter(p string, opt IndentOptions, w io.Writer) io.Writer

Create an indent writer

func NormalizeDiacritics

func NormalizeDiacritics(s string) string

Convert characters with diacritical marks to their unaccented/base counterparts. See also: http://stackoverflow.com/questions/26722450/remove-diacritics-using-go

func NormalizeJoin

func NormalizeJoin(l []string, d, f string) string

Normalize a list, using a special final delimiter between the last two elements.

func NormalizeString

func NormalizeString(s string) string

Normalize a string for general purpose matching

func NormalizeTerms

func NormalizeTerms(s string) string

Normalize query terms

func ParseRanges

func ParseRanges(s string, b []int) ([][]int, error)

Parse a series of ranges from text. Multiple ranges can be represented in a comma-delimited list. Individual numbers in the list are treated as a range that includes only that number.

An empty bound in a range is interpreted as "all the numbers from the constraining bound to the other bound". For example, the range "-10", with constraining bounds of [0, 100] means the range "0-10".

Contiguous ranges are merged together.

For example, the input: 0-5,5,6,7,8-10 produces: [[0,10]]

And the input: 0-5,7,9-10 produces: [[0,5],[7,7],[9,10]]

func ParseRangesFunc

func ParseRangesFunc(s string, b []int, d string, c NumberParser) ([][]int, error)

Parse ranges where the values are parsed by a function

func Stringer

func Stringer(v interface{}) string

Convert a value to a reasonable string representation

func StripControl

func StripControl(s string) string

Strip out control characters in place

func Truncate

func Truncate(s string, n int, x string) string

Truncate a string to n characters (not bytes). If the string is truncated, the provided suffix is appended. Something like ' [...]' would be appropriate as a suffix to indicate that text was removed.

Types

type IndentOptions

type IndentOptions uint32
