Insert sequential numbers at start of lines

deleelee

I know how to use the Column Editor to insert sequential numbers at the start of lines but is it possible to create a macro for this? I’ve tried doing the following:

Move cursor to start position.
Start Recording macro.
Press Alt+C to open Column Editor.
Enter 1 for initial number, 1 for increase, click OK.
Stop Recording macro.

The macro records but when I select Playback nothing happens.

@deleelee ,

The macro language is not all-capable, unfortunately. The only dialog-based action which it can record is search/replace – and since the Column Editor is a dialog that isn’t the search/replace, the macro cannot record/replicate its action

I thought that might be the case so thanks for confirming it for me :-)

While it may not be possible as a macro, it could certainly be “scripted” if you are interested in that type of solution.

I don’t think you read my post because I’ve already said I know how to do that.

Yes I would be interested in that type of solution. Do you have a script in mind?

You didn’t really say a whole lot about what you want to end up with, but here’s a script that demos some capability. I call it InsertLineNumbersOnLines.py:

# -*- coding: utf-8 -*-
from __future__ import print_function

from Npp import *
import math

#-------------------------------------------------------------------------------

class ILNOL(object):

    def __init__(self):
        num_digits_in_line_num = int(math.log(editor.getLineCount(), 10)) + 1
        line_list = editor.getText().splitlines()
        line_list2 = []
        for (line_nbr, line_content) in enumerate(line_list):
            line_list2.append('{n:>{d}}:{c}'.format(n=line_nbr+1, c=line_content, d=num_digits_in_line_num))
        eol = ['\r\n', '\r', '\n'][editor.getEOLMode()]
        editor.setText(eol.join(line_list2))

#-------------------------------------------------------------------------------

if __name__ == '__main__': ILNOL()

The script will put line numbers at the start of every line, example:

It may be worth noting that the script above is similar to the functionality of the deprecated TextFX plugin’s function: TextFX > TextFX Tools > Insert Line Numbers.

Here’s a slightly modified version that is even more similar, I call this one TextFxInsertLineNumbers.py:

# -*- coding: utf-8 -*-
from __future__ import print_function

from Npp import *
import inspect
import os

#-------------------------------------------------------------------------------

class TFILN(object):

    def __init__(self):
        self.this_script_name = inspect.getframeinfo(inspect.currentframe()).filename.split(os.sep)[-1].rsplit('.', 1)[0]
        if editor.getSelectionEmpty():
            self.mb('No text selected')
            return
        (start_line, end_line) = editor.getUserLineSelection()
        start_pos = editor.positionFromLine(start_line)
        end_pos = editor.getLineEndPosition(end_line)
        line_list = editor.getRangePointer(start_pos, end_pos - start_pos).splitlines()
        line_list2 = []
        for (line_nbr, line_content) in enumerate(line_list):
            line_list2.append('{n:08} {c}'.format(n=line_nbr+1, c=line_content))
        eol = ['\r\n', '\r', '\n'][editor.getEOLMode()]
        editor.setTarget(start_pos, end_pos)
        editor.beginUndoAction()
        editor.replaceTarget(eol.join(line_list2))
        editor.endUndoAction()

    def mb(self, msg, flags=0, title=''):  # a message-box function
        return notepad.messageBox(msg, title if title else self.this_script_name, flags)

#-------------------------------------------------------------------------------

if __name__ == '__main__': TFILN()

Thanks for both of these. Sorry I wasn’t more specific. What would be great would be a script where I just select the lines I want numbered and insert sequential numbers starting from one followed by a closing parentheses ie: 1) 2) 3)

Now I’m not exactly a coding newbie but I’ve not really dealt with Python before. If I have Python installed on my PC do I just run the script or do I load it into Npp (as a macro or some other method)?

No. You install the PythonScript plugin, which comes with an embedded Python interpreter, and follow the instructions in the FAQ on how to run a script using PythonScript

Thank you so much, Peter! :-D
