Get current line and col from Script

[HisRoyalRedness]

Hi there,

Anyone know how to get the current line and column no from a script? I'm doing a find from the top of the document, and if nothing is found, I'd like to go back to the point from which I started. Maybe there's a better way then recording line and column before starting, like setting a bookamrk? Anyone know how to do this?

see online help.
togglebookmark / gotobookmark.

Or type sth. like "#myuniquemarkersign#", do your action and then make a search and replace to reposition and remove the marker.

Thanks, that will work as a second option. First prize is the get the current line number. Anyone?? The insertion of some string to search for is a bit messy...

There are currently nothing of the sort available, it's been requested tho (I suggest you add your request as well so they know more like to have this feature) support@idmcomp.com

You have all the commands in the help file on a single page (Getting started -> Scripting commands)

Thanks, I checked through the list, but was hoping there were a few 'undocumented' features I didn't know about. Oh well...

I'll send of the feature request right away. Thanks for the replies...

Well, with an (not really nice) trick we can get the current column:

Code: Select all

function getCol() {
  var i = 0;
  while (true) {
    if (UltraEdit.activeDocument.isColNum(i)) {
       return i;
    }
    i++;
  }
  return i;
}

var iCol = 0;
iCol = getCol();
UltraEdit.activeDocument.write(String(iCol));
UltraEdit.activeDocument.write("Fertig");

VERY fast

OK OK, This one is faster:

Code: Select all

function getCol() {
  //get the current Column.
  //speed-optimized. Hop to the right in steps. Then, when being bigger, hop back one by one.
  //Kind of "binary-tree" for fools ;-)
  var i = 1;
  var iStep = 10;
  while (true) {
    if (UltraEdit.activeDocument.isColNumGt(i)) {
       //still too much on the left side.
       i = i + iStep;
    }
    else
    {
      //hopped too far. go a little bit back
      for (var j = 0; j < iStep; j++) {
        //UltraEdit.document[1].write(String(j));
        if (UltraEdit.activeDocument.isColNum(i-j)) {
          //match !
          //UltraEdit.document[1].write("Match mit " + String(j));
          return (i-j);
        }
      }
    };
  }
  return i;
}

var iCol = 0;
iCol = getCol();
UltraEdit.activeDocument.write(String(iCol));
UltraEdit.activeDocument.write("Fertig");

Is this useful ?

youd be best off starting at say 40 and going up/down by 20
then when you over/understep reduce the 20 to 10 and repeat and keep reducing until step size is 1, and buy the time its 1 you should have found the column.

[HisRoyalRedness]

I like that! Sure, it's not the prettiest way of doing it, but it's the best so far in my very humble opinion. Thanks!

The files I'm working with are quite large though, so I think I'll start with a large number (say, 10000) and then either double or halve it until the current line is found.

Yes, but implementing this (http://en.wikipedia.org/wiki/Binary_search_algorithm) would not really be faster in files (lines) usually beeing not longer than 100 chars.
Maybe somebody else wants to implement it...
And: On a binary search you need an upper limit eg. 256 or 512 chars.
Mine works also with 1234 chars.

Oops! Spoke to soon The last post was a column search, not a line search...

I like this idea, and wanted to add a CurCol property to the activeDocument object, but it doesn't seem to work. Anyone know what's wrong with the code below? I'm fairly new to JavaScript, so it's probably something I'm not understanding.

Code: Select all

function getCol() {
  //get the current Column.
  //speed-optimized. Hop to the right in steps. Then, when being bigger, hop back one by one.
  //Kind of "binary-tree" for fools ;-)
  var i = 1;
  var iStep = 10;
  while (true) {
    if (this.isColNumGt(i)) {
       //still too much on the left side.
       i += iStep;
    }
    else
    {
      //hopped too far. go a little bit back
      for (var j = 0; j < iStep; j++) {
        if (this.isColNum(i-j)) {
          return (i-j);
        }
      }
    };
  }
  return i;
}

UltraEdit.activeDocument.prototype.CurCol = getCol;


TIA

Here a Script to get line and column.
It is not good to use with huge documents and a selected text will be lost, but just an idea.

Code: Select all

var endOfLine = "\r\n";
UltraEdit.activeDocument.selectToTop();
myLines = UltraEdit.activeDocument.selection.split(endOfLine);
line = myLines.length;
column = myLines[myLines.length -1].length + 1;
UltraEdit.getString("Line: " + line + " Column: " + column, 1);
UltraEdit.activeDocument.gotoLine(line, column);

Very good.
Tried it on a 1500 lines 70k TXT-doc and it was still fast.
Should do the job for me UNTIL HOPEFULLY IDM IMPLEMENTS IT.

If you have tabs in your document you shoul have to use this script:

Code: Select all

var endOfLine = "\r\n";
var tab = "\t";
var spacesForTab = 2;

var column = 1;
var line;
UltraEdit.activeDocument.selectToTop();
myLines = UltraEdit.activeDocument.selection.split(endOfLine);
line = myLines.length;
tabsInLastLine = myLines[myLines.length -1].split(tab).length - 1;
column += tabsInLastLine * ( spacesForTab - tab.length ) + myLines[myLines.length -1].length;
myLines = null;
UltraEdit.activeDocument.gotoLine(line, column);
UltraEdit.getString("Line: " + line + " Column: " + column, 1);
