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

Sorry it’s taken me so long to check your scripts out. Thank you so much, they’re great but I’d like a kind of hybrid of them both.

InsertLineNumbersOnLines - Inserts numbers on all lines with the numbers followed by a colon.

TextFxInsertLineNumbers - Inserts numbers only on selected lines but with leading zeros.

I’d like to insert numbers only on selected lines, with no leading zeros, and numbers followed by a colon or a closing parentheses.

UPDATE: I managed to figure it out myself and modified your TextFxInsertLineNumbers script. I now have it inserting numbers with no leading zeros followed by a closing parentheses. Thank you so much for your help.

However, is it possible to have it insert numbers only for selected lines but exclude any selected lines that are empty?

but exclude any selected lines that are empty?

Sure, most anything is possible with programming.
You’d want to look for a line-length of zero (e.g. len(line_content) == 0) and then NOT insert a line number at the start of such lines, by appending only the content to the second list. Of course, this would cause gaps in your line numbering any time a blank line occurs, so you might need to maintain the line number counter yourself.

Since you’ve already made changes to the script, go ahead and make some more! :-)

Thanks yet again. I’ll check it out :-D
