Regex Matching Description part of a JS Doc string - node.js

Question

I am trying to match the description part (line without a # symbol) of JS doc string. Here are a couple of exmaples of doc strings.
/**
* This is a doc string
* #param withArg description of withArg
* #param withArg2 description of withArg2
*/
/**
* This is an other doc string
* This is second line of description.
*/
This seems to work in regex editor:
/\*\S*(.*?)(#)/
see: https://regexr.com/4dfbn
But in javascript:
https://jsbin.com/qekisogula/1/edit?html,js,console
Any ideas on what is going on ?
Thanks a lot
UPDATE:
Expected output
Example 1:
This is an other doc string
Example 2:
This is an other doc string, This is second line of description.

Answer 1

I would actually take the approach of reading the file line by line and using some rudimentary parsing logic:
var lineReader = require('readline').createInterface({
input: require('fs').createReadStream('file.in')
});
var start = false;
lineReader.on('line', function (line) {
if (line.startsWith("/**") {
start = true;
}
else if (line.startsWith("*/")) {
start = false;
}
else if (start && !line.includes("#param")) {
console.log("doc string: ", line);
}
});
The logic here is that we use a boolean flag start to keep track of whether we are inside a comment with doc strings. Upon hitting /** the flag is turned on, and upon hitting */ the flag is turned off. If we encounter a line which does not contain #param, then we echo it to the console.
