No useful script. Just an little lesion.
Loop virtually through all lines in file
The cursor will not move!
We access each line by its number only.

– – –

Best to learn is to do some lessons.
So i will show my steps creating an macro for others.

I am not saying that this is the best way to do it,
it is just an start.

If you have an better way to do it, or other
suggestions, just reply :-)

	////Loop virtually through all lines in file

	////(Cursor will not move! 

	//// We access each line by its number only.)

	

	LinesInFile = document.GetLines();

	LineToStart = 1;

	alert ("Lines in file: " + LinesInFile);

	

	////For Each Line in File Do:

	for (var LINE = LineToStart; LINE <= LinesInFile; LINE++)

	 {

	  ////Get the lines content:

	  str = document.GetLine(LINE);

	  	

	  ////===Example use, add here your own code======

	       ////Show the content and ask to continue:

	       bAnswer = confirm("Processing line " + LINE 

	          + ".  Content:nn"

	    	  + str + "nnnn"

		  + "Continue?" );

	  	  

	       ////What to do If you pressed cancel?:

	       if (bAnswer == false){break;} 

	        //use "break; to exit the "for" loop only

	        //use "quit();" to cancel the whole script

	  ////===END of Example use, =====================

	 }

	

	 alert("All done. Script quits.");

No useful script. Just an little lesion.
Loop virtually through only the selected lines in file.
The cursor will not move!
We access each line by its number only.

	////Loop through Selection

	

	////Object handling to save always typing of 'document.selection':

	var d = document;

	var s = d.selection;

	

	

	////////Get the selected text to work on:

	////////(Depends if already something is selected or not)

	if (s.IsEmpty)

	{

	    ////If document.selection is empty:

	    vWasAnSelection = false;

	

	    ////Alternative one

	    //alert("Nothing selected, script quits. Please select and start again.");

	    //quit();

	

	    ////Alternative two

	    alert("Nothing selected, script will select whole text for you.");

	    s.SelectAll();

	

	}else{ 

	

	    ////If there was an selection already:

	    vWasAnSelection = true;

	    alert("Selected text to work on: n" +  s.text);

	}

	

	

	

	////////Get start and end line of the selection:

	///Returns the line number of the top of the selection.

	  FirstSelLine = s.GetTopPointY(eePosLogical);

	///Returns the line number of the bottom of the selection.

	  LastSelLine = s.GetBottomPointY(eePosLogical);

	

	

	

	////For Each Line In SelectedLineS Do:

	for( Line = FirstSelLine; Line <= LastSelLine; Line++)

	{

	    ////  <<< Your code here >>>

	    //// Here an simple example:

	    ret = Confirm(d.GetLine(Line));

	    if (ret == false) {if (!vWasAnSelection){s.Collapse();} Quit();}

	}

	

		

	////If there was no selection do an UnSelectAll at the end:

	if (!vWasAnSelection) s.Collapse();

Some examples for section:

////Delete start of line (Remove first sign/char):
redraw = false;
document.selection.SetActivePoint( eePosLogical, 1, Line );
str = document.GetLine( Line );
if (str != “”)
{
document.selection.StartOfLine();
document.selection.Delete();
}

////Delete end of line (Remove last sign/char):
redraw = false;
document.selection.SetActivePoint( eePosLogical, 1, Line );
str = document.GetLine( Line );
if (str != “”)
{
document.selection.EndOfLine();
document.selection.DeleteLeft();
}

However, for just this task there
would be an easier solution then such an big script as shown above:

//Remove first sign from selected lines
redraw = false;
document.selection.Replace(“^.”,””, eeReplaceSelOnly | eeReplaceAll | eeFindReplaceRegExp);
document.HighlightFind = false;

//Remove last sign from selected lines
redraw = false;
document.selection.Replace(“.$”,””, eeReplaceSelOnly | eeReplaceAll | eeFindReplaceRegExp);
document.HighlightFind = false;
