Remove everything but all regex matches

[Piero512]

I have written a script that interprets the selected text as a RegExp, and replaces fullText with the text matched by the regexp joined with newlines, but I can't get it to work.

/**
	{
		"api":1,
		"name":"Regex select",
		"description":"Use selection as regex input, removes it from the input and then returns all matches",
		"author":"piero512",
		"icon":"quote",
		"tags":"boop,state,script,debug,new,create"
	}
**/

function removeRegexInput(selected, text) {
    return text.replace(selected, '');
}
function copyRegexMatches(regexp, text) {
    return text.match(regexp);
}
function main(input) {
    try {
        if (!input.isSelection) {
            input.postError('You have to select something before calling this script!');
        }
        else {
            var copy_selection = input.selection;
            var removedRegex = removeRegexInput(input.selection, input.fullText);
            var regexp = RegExp(copy_selection, 'gm');
            var matches = copyRegexMatches(regexp, removedRegex);
            var newText = matches.join('\n');
            console.log(newText);
            input.fullText = newText;
        }
    }
    catch (e) {
        input.postError("Unknown error: " + e.toString());
    }
}

!input.isSelection should be !input.selection. In case you didn't know, there is instructions to debug scripts.

I like the idea of this script, would be great with #122.

Well, I should have added what was wrong. The else branch runs when there is a selection (as is), but the expected behavior is to replace the text in the window completely with the newText var but it just doesn't work for me 😢,nor it throws exceptions.
