Best way to get lines in a Document?

I've just started getting into the Open API, so I apologize in advance if

this is a stupid question... (coding at 2 AM probably doesn't help either

 

What's the best way to tokenize a Document into individual lines?  I've

found the getLineCount() method to get the number of lines, but i'd like to

know the best way to iterate over each line.

 

Should I just wrap the char array returned by doc.getChars() with a

CharArrayReader and BufferedReader like this:

 

   CharArrayReader stringReader = new CharArrayReader(doc.getChars());

   BufferedReader in = new BufferedReader(stringReader);

 

So that I could later call in.readLine() in a loop?

 

Or is there a better way?

 

thanks!

Re: Best way to get lines in a Document?

As a followup, how can I get the user's line separator preference?  I don't

see a relevant method in EditorSettings.

 

thanks,

You actually do not need this in editor/document. Document always has single

'\n' line separator in it. User preference is taken into an account while

loading/saving a file.

Re: Best way to get lines in a Document?

Would this be satisfactory?

 

    Document doc = ...;

    char[] docText = doc.getChars();

    int lineCount = doc.getLineCount();

    for (int i = 0; i < lineCount; i++) {

      int lineStart = doc.getLineStartOffset(i);

      int lineEnd = doc.getLineEndOffset(i);

      String lineText = new String(docText, lineStart, lineEnd - lineStart);

 

      // Do something with lineText...

    }
