Replace multiple substrings in a string in turn
npm install string-multiple-replace> Replace multiple substrings in a string in turn.
Replace all substring matches in a string with an mapping object that is table of replaceThis: withThis, and you can provide a sequencer to decide the order of replacement.
``sh`
npm install --save string-multiple-replace
or
`sh`
yarn add string-multiple-replace
`js
const multiReplace = require('string-multiple-replace');
const input = "abcde";
const matcherObj = {
"a": "b",
"b": "c",
"c": "d",
"d": "e"
}
multiReplace(input, matcherObj, ["a", "b", "c", "d"]); // eeeee
multiReplace(input, matcherObj); // bcdee
`
- Example-1
`js
const multiReplace = require('string-multiple-replace');
const input = "I'm only brave when I have to be. Being brave doesn't mean you go looking for trouble.";
const matcherObj = {
"brave": "cowardly",
"trouble": "escape"
}
const sequencer = ["brave", "trouble"];
multiReplace(input, matcherObj, sequencer);
//I'm only cowardly when I have to be. Being cowardly doesn't mean you go looking for escape.
`
- Example-2
`js
const multiReplace = require('string-multiple-replace');
const input = "I'm only brave when I have to be. Being brave doesn't mean you go looking for trouble.";
const matcherObj = {
"brave": "cowardly",
"trouble": "escape"
}
multiReplace(input, matcherObj, keys => keys);
//I'm only cowardly when I have to be. Being cowardly doesn't mean you go looking for escape.
`
> multiReplace(input, matcherObj[,sequencer])
The original string is replaced in turn according to the matcherObj, where sequencer determines the replacement order, and the existence state of sequencer determines whether the last operation overwrites the previous operation.
#### input
Type: string
Required
> A string to be processed.
#### matcherObj
Type: object
Required
> An object that represents a string replacement mapping.
#### sequencer
Type: function, array
Required：false
A function that takes the keys of matcherObj, and return an suquence array.
>Upgrade Instruction: the existence state of sequencer` determines whether the last operation overwrites the previous operation.
