Functions ¶
func Contain ¶
Contain find a rune `c` inside `s`. If `c` found in `s` it will return boolean true and index of `c` in `s`; otherwise it will return false and -1.
Example ¶
line := []rune(`a b c`)
found, idx := Contain(line, 'a')
fmt.Printf("%t %d\n", found, idx)
found, idx = Contain(line, 'x')
fmt.Printf("%t %d\n", found, idx)
Output: true 0 false -1
func Diff ¶
Diff return the difference between two slice of rune.
Example ¶
l := []rune{'a', 'b', 'c', 'd'}
r := []rune{'b', 'c'}
fmt.Printf("%c\n", Diff(l, r))
Output: [a d]
func EncloseRemove ¶
EncloseRemove given a line, remove all characters inside it, starting from `leftcap` until the `rightcap` and return cutted line and changed to true.
If no `leftcap` or `rightcap` is found, the line will unchanged, and returned status will be false.
Example ¶
line := []rune(`[[ ABC ]] DEF`)
leftcap := []rune(`[[`)
rightcap := []rune(`]]`)
got, changed := EncloseRemove(line, leftcap, rightcap)
fmt.Printf("'%s' %t\n", string(got), changed)
Output: ' DEF' true
func FindSpace ¶
FindSpace find any unicode spaces in line start from index `startAt` and return their index. If no spaces found it will return -1.
Example ¶
line := []rune(`Find a space`)
fmt.Printf("%d\n", FindSpace(line, 0))
fmt.Printf("%d\n", FindSpace(line, 5))
Output: 4 6
func TokenFind ¶
TokenFind will search token in text starting from index `startAt` and return the position where the match start.
If no token is found it will return -1.
Example ¶
line := []rune("// Copyright 2018, Shulhan <ms@kilabit.info>. All rights reserved.")
token := []rune("right")
at := TokenFind(line, token, 0)
fmt.Printf("%d\n", at)
Output: 7
