I get the object message via http protocol.
This object has the body property.
message.body: 'Denversaurus $24.90' +
'Bread with sesame, artisan meat, cheddar, Jurassic sauce, mustard and honey, lettuce, tomato and pickles.'
I apply the following regex to that variable:
const regex = new RegExp(/([\w\dà-ú'" ]+)R\$ ([\d+,\.]+)[\n\r]([ \w\dà-ú'"\.,\+\*\(\)]+)/)
const arrayMatch = regex.exec(message.body)
On linux, I get the expected result, but on windows, the arrayMatch variable returns with the value null. And I can't solve it.
Does anyone have the solution?
your regex is incorrect . please test all patterns first with online tools like : https://debuggex.com
As for this, I have to make it clear to you that all APIs implemented by Node Js are multiplatform unless the command is specific to a particular operating system. But in the case of regex, it is supported by all operating systems.
Also, when you want to build a regex with a constructor, its argument must be a string.
let regex1 = /(\w+)/gi;
//or
let regex2 = new RegExp("(\\w+)", "gi")
They must only differ in line ends: "\n" is Linux-style and "\r\n" is Windows-style.
Use
const regex = new RegExp(/([\wà-ú'" ]+)R\$ ([\d+,\.]+)[\n\r]+([ \wà-ú'"\.,\+\*\(\)]+)/)
