Groovy not removing elemnts from array - groovy

Question

I want to remove strings starting with # or // from the lines array.
It is not working.
Here is the code (excluding the preliminaries like reading the file etc):
def file = new File("$_file").text.replaceAll("\\r\\n|\\r|\\n", " ");
String[] lines_ = file.split("\\s*;\\s*");
println(lines_);
for(line in lines_)
{
if(line.take(1) =='#' || line.take(2) == '//')
{
remove(lines_ , line);
}
}
Here is the remove function
public static String[] remove(String[] input, String deleteMe)
{
if (input != null) {
List<String> list = new ArrayList<String>(Arrays.asList(input));
for (int i = 0; i < list.size(); i++) {
if (list.get(i).equals(deleteMe)) {
list.remove(i);
}
}
return list.toArray(new String[0]);
} else {
return new String[0];
}
}
Here is the $_file
canvas cvs {
width:100,
dfdf:60
}
;
//this is a comment;
#also a comment;
sprite ball{
body : hr,
Image: here
}
;
Thanks.

Answer 1

You can read the lines from the file with readLines(), then just call findAll like so:
String[] lines = new File("$_file")
.readLines()
.findAll { !it.startsWith('#') && !it.startsWith('//') }

Answer 2

I did it!
I changed remove function to:
static String[] remove(String[] str_array , String what){
List<String> list = new ArrayList<String>(Arrays.asList(str_array));
list.remove(what);
str_array = list.toArray(new String[0]);
return str_array;
}
and remove(lines_,line) to lines_ = remove(lines,line)
And its ok now!
