Functions

func FilteredJoin

func FilteredJoin(sList []string, separator ...string) (line string)

FilteredJoin is like strings.Join but ignores empty strings. defauklt separator is single space \x20

func FilteredJoinWithHeading

func FilteredJoinWithHeading(sList []string, separator ...string) (line string)

FilteredJoinWithHeading takes a string slice of heading-value pairs and only outputs those strings that are non-empty. {"head1", "first", "head2, ""} → "head1: first"

func Fit

func Fit(s string, width int, pad bool) (s2 string)

Fit return a string fitted to certain column width

• if width < 1, no change
• if s’ length equals width, no change
• if s’ length less than width, pad with spaces if pad true, otherwise no change
• otherwise cut s in the center and replace with single epsilon "…" character

func FitValueAndLabel

func FitValueAndLabel(width int, value, label string, pad bool) (s string)

fitValueAndLabel trums a value and its label to fit into width

• if pad is true and result shorter than width, s is padded with spaces to reach width

func IsDefaultValue

func IsDefaultValue(pt interface{}) (isDefault bool)

func QuoteList

func QuoteList(strs []string) string

QuoteList formats a string slice using %q into a single space-separated string

func StrSliceContains

func StrSliceContains(ss []string, s string) bool
