strings

func (*Namespace) Chomp ¶

func (ns *Namespace) Chomp(s interface{}) (interface{}, error)

Chomp returns a copy of s with all trailing newline characters removed.

func (*Namespace) Contains ¶

func (ns *Namespace) Contains(s, substr interface{}) (bool, error)

Contains reports whether substr is in s.

func (*Namespace) ContainsAny ¶

func (ns *Namespace) ContainsAny(s, chars interface{}) (bool, error)

ContainsAny reports whether any Unicode code points in chars are within s.

func (*Namespace) CountRunes ¶

func (ns *Namespace) CountRunes(s interface{}) (int, error)

CountRunes returns the number of runes in s, excluding whitepace.

func (*Namespace) CountWords ¶

func (ns *Namespace) CountWords(s interface{}) (int, error)

CountWords returns the approximate word count in s.

func (*Namespace) FindRE ¶

func (ns *Namespace) FindRE(expr string, content interface{}, limit ...interface{}) ([]string, error)

FindRE returns a list of strings that match the regular expression. By default all matches will be included. The number of matches can be limited with an optional third parameter.

func (*Namespace) HasPrefix ¶

func (ns *Namespace) HasPrefix(s, prefix interface{}) (bool, error)

HasPrefix tests whether the input s begins with prefix.

func (*Namespace) HasSuffix ¶

func (ns *Namespace) HasSuffix(s, suffix interface{}) (bool, error)

HasSuffix tests whether the input s begins with suffix.

func (*Namespace) Repeat ¶ added in v0.42.1

func (ns *Namespace) Repeat(n, s interface{}) (string, error)

Repeat returns a new string consisting of count copies of the string s.

func (*Namespace) Replace ¶

func (ns *Namespace) Replace(s, old, new interface{}) (string, error)

Replace returns a copy of the string s with all occurrences of old replaced with new.

func (*Namespace) ReplaceRE ¶

func (ns *Namespace) ReplaceRE(pattern, repl, s interface{}) (_ string, err error)

ReplaceRE returns a copy of s, replacing all matches of the regular expression pattern with the replacement text repl.

func (*Namespace) RuneCount ¶ added in v0.42.1

func (ns *Namespace) RuneCount(s interface{}) (int, error)

RuneCount returns the number of runes in s.

func (*Namespace) SliceString ¶

func (ns *Namespace) SliceString(a interface{}, startEnd ...interface{}) (string, error)

SliceString slices a string by specifying a half-open range with two indices, start and end. 1 and 4 creates a slice including elements 1 through 3. The end index can be omitted, it defaults to the string's length.

func (*Namespace) Split ¶

func (ns *Namespace) Split(a interface{}, delimiter string) ([]string, error)

Split slices an input string into all substrings separated by delimiter.

func (*Namespace) Substr ¶

func (ns *Namespace) Substr(a interface{}, nums ...interface{}) (string, error)

Substr extracts parts of a string, beginning at the character at the specified position, and returns the specified number of characters.

It normally takes two parameters: start and length. It can also take one parameter: start, i.e. length is omitted, in which case the substring starting from start until the end of the string will be returned.

To extract characters from the end of the string, use a negative start number.

In addition, borrowing from the extended behavior described at http://php.net/substr, if length is given and is negative, then that many characters will be omitted from the end of string.

func (*Namespace) Title ¶

func (ns *Namespace) Title(s interface{}) (string, error)

Title returns a copy of the input s with all Unicode letters that begin words mapped to their title case.

func (*Namespace) ToLower ¶

func (ns *Namespace) ToLower(s interface{}) (string, error)

ToLower returns a copy of the input s with all Unicode letters mapped to their lower case.

func (*Namespace) ToUpper ¶

func (ns *Namespace) ToUpper(s interface{}) (string, error)

ToUpper returns a copy of the input s with all Unicode letters mapped to their upper case.

func (*Namespace) Trim ¶

func (ns *Namespace) Trim(s, cutset interface{}) (string, error)

Trim returns a string with all leading and trailing characters defined contained in cutset removed.

func (*Namespace) TrimLeft ¶ added in v0.27.1

func (ns *Namespace) TrimLeft(cutset, s interface{}) (string, error)

TrimLeft returns a slice of the string s with all leading characters contained in cutset removed.

func (*Namespace) TrimPrefix ¶

func (ns *Namespace) TrimPrefix(prefix, s interface{}) (string, error)

TrimPrefix returns s without the provided leading prefix string. If s doesn't start with prefix, s is returned unchanged.

func (*Namespace) TrimRight ¶ added in v0.27.1

func (ns *Namespace) TrimRight(cutset, s interface{}) (string, error)

TrimRight returns a slice of the string s with all trailing characters contained in cutset removed.

func (*Namespace) TrimSuffix ¶

func (ns *Namespace) TrimSuffix(suffix, s interface{}) (string, error)

TrimSuffix returns s without the provided trailing suffix string. If s doesn't end with suffix, s is returned unchanged.

func (*Namespace) Truncate ¶

func (ns *Namespace) Truncate(a interface{}, options ...interface{}) (template.HTML, error)

Truncate truncates a given string to the specified length.
