func CountByteLeft ¶

func CountByteLeft(s string, b byte) int

CountByteLeft counts the number of b from the lest side of s until non b found. For example, CountByteLeft("aabc",'a') returns 2.

func CountByteRight ¶

func CountByteRight(s string, b byte) int

CountByteRight counts the number of b from the right side of s until non b found. For example, CountByteRight("abcc",'c') returns 2.

func CutLeftByte ¶

func CutLeftByte(s string, c byte) (before, after string, found bool)

CutLeftByte slices the given string s at the first instance of c, returning the text before and after the separator of c. The found result reports whether c appears in s. The separator c is not contained both before and after. If the separator c does not appear in s, cut returns s, "", false. See also strings.Cut and strings.IndexByte.

func CutLeftRune ¶

func CutLeftRune(s string, r rune) (before, after string, found bool)

CutLeftRune slices the given string s at the first instance of r, returning the text before and after the separator of r. The found result reports whether r appears in s. The separator r is not contained both before and after. If the separator r does not appear in s, cut returns s, "", false. If the given r is not valid UTF-8 rune, it also returns s, "", false. CutLeftRune uses Brute Force strategy for all s. See also strings.IndexRune.

func CutRightByte ¶

func CutRightByte(s string, c byte) (before, after string, found bool)

CutRightByte slices the given string s at the last instance of c, returning the text before and after the separator of c. The found result reports whether c appears in s. The separator c is not contained both before and after. If the separator c does not appear in s, cut returns s, "", false. See also strings.Cut and strings.LastIndexByte.

func CutRightRune ¶

func CutRightRune(s string, r rune) (before, after string, found bool)

CutRightRune slices the given string s at the last instance of r, returning the text before and after the separator of r. The found result reports whether r appears in s. The separator r is not contained both before and after. If the separator r does not appear in s, cut returns s, "", false. If the given r is not valid UTF-8 rune, it also returns s, "", false. CutLeftRune uses Brute Force strategy for all s. See also strings.IndexRune.

func Match ¶

func Match(pattern, str string) (bool, error)

Match reports whether the str matches the pattern. Match is simpler and faster match function similar to path.Match or path/filepath.Match. The only error returned is ErrBadPattern when the given pattern has single "\\" at the end of its pattern.

The pattern syntax is:

pattern:
	{ term }
term:
	'*'         matches any sequence of characters
	'?'         matches any single character
	c           matches character c (c != '*', '?')
	'\\' c      matches character c
