Find ksh functions using nodejs regex - node.js

Question

I want to write some regex which matches the following: any char regargless how often and then and opening and closing bracket. Also I don't want it to match if there is a # infront of it.
Here is what I tried so far:
\s*^(?!#)*[A-Za-z0-9_]*\(\)
The problem is that this regex seems to match every line in the test file, not just the functions that I want.
Have a great day
EDIT:
function match(array, regex) {//Rematcher
back = [];
for (let i = 0; i < array.length; i++) {
let line = array[i];
if (regex.test(line)) {
back.push(line);
}
}
return back
}
function find(text) {//function finder
let reg = new RegExp("^(?!#)*\w*\(\)");
return reMatcher.match(text, reg);
}
let content = fs.readFileSync(file, "UTF-8");//starting point
let functions = find_functions.find(content);
content = content.split("\n");
//Testfile
meldet()
{
if true
then
if true
then
echo Pseudocode
fi
echo Pseudocode
fi
}
The regex should only match the first line, but instead it matches every line and also it shouldn't match on lines where a # is before the function header

Answer 1

In the pattern \s*^(?!#)*[A-Za-z0-9_]*\(\) you can omit the \s* before the start of the line anchors.
As you don't match a # in the character class, you can also omit the negative lookahead (?!#)
Instead of using reMatcher.match(text, reg);, you could use match on the text variable.
Note to double escape the backslashes in the RegExp constructor.
You could update the function find to:
function find(text) {
let reg = new RegExp("\\s*^(?!#)*[A-Za-z0-9_]*\\(\\)");
return text.match(reg)[0]; // Or first check the value before indexing
}
