Insert sequential numbers at start of lines

Here’s a slightly modified version

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?

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

@Alan-Kilborn I know it’s years later, but i found myself using your script. I’m a total noob when it comes to programming, all i could do is modify what goes after the numbers.
Now, how could i delete what the script just did (i.e delete the numbers, but leave the lines like they were before the script ran) ? I know i can use Undo to do it on the spot, but let’s say i wanna undo the numbering a day after.

@Ionut-Dorin

You don’t need programming to delete the line numbers that were inserted.

Here’s how to do it:

Move the caret to line 1 and column 1
Press Shift+Alt+b to Begin Select in Column mode
Move the caret to the last line and put it right after the last digit of the line number (previously added by the script)
Press Shift+Alt+b again to End Select in Column mode

At this point you should have the line numbers selected in a rectangular block so simply pressing Delete should eliminate them.

@Alan-Kilborn Okay, i knew how to do that, but it does not help me.
First, i’d have to do it twice, because i set the script up to put a number, then :, then a space (5: ), so till 9 its 3 characters long and after is 4 characters long.
And again, i have to do this multiple times in a document, every day and using the column mode is a bit tedious. I was hoping that i could do it with a script.
Now, i select the text i need, press a key and your script instantly does its job. I’d like to have the same thing with deleting, but i don’t know if it’s possible or not. :)

It would have been better to just show some of this text rather than describing it…

But I think if you do a replacement operation it will be good?:

Find: ^\d+:
Replace: set to nothing
Search mode: Regular expression
Options: Wrap around
Action: Replace all

You can record this replacement op as a macro.

@Alan-Kilborn
1: Line content
2: Line content
3: Line content
4: Line content
5: Line content
6: Line content
7: Line content
8: Line content
9: Line content
10: Line content
11: Line content
12: Line content
… and to become
Line content
Line content
Line content
Line content
etc.
Find: ^\d+: doesn’t work and plus, i don’t need it for the whole document, just for the lines i select.

If you did exactly what I said to do, I see no reason why it wouldn’t work on your sample data.

i don’t need it for the whole document, just for the lines i select.

Ok, so don’t checkmark Wrap around but make your selection first and then checkmark In selection.

Ionut Dorin

@Alan-Kilborn Yes, that did it, I think i read too fast and didn’t see that you said “Search mode: Regular expression” and i didn’t check that, so maybe that’s why it didnt work.
Also, i turned it into a macro for ease of use.
Thank you so much for your help and patience, you’re a lifesaver.

Hi Alan, the scripts have been working really well, thank you so much for your help. One thing I’ve noticed is that, when using the script for selected lines, it has to be a block selection for the script to work. I can’t select individual lines (eg: line 1, line 4, line 7) and insert numbers at that the start of only those lines.

I’ve tried:

Multi-selection using Ctrl + single-click at the start of each line.
Multi-selection using Ctrl + single-click at the start and end of each line.
Multi-selection using Ctrl + double-click to select the first word of each line.

Numbers 1 & 2 don’t actually select any text so when I run the script I get a “No text selected” message.
Number 3 only places a number at the start of the line for the last word I select.

Is it possible or am I expecting more than the script can achieve?

@deleelee

You must be referring to the TextFxInsertLineNumbers.py script, because the other script discussed in this topic, InsertLineNumbersOnLines.py, doesn’t deal with any selected text at all.

Here’s a modified version of the script I’m calling TextFxInsertLineNumbers2.py :

# -*- coding: utf-8 -*-
