Add number in each word by Notepad++

@Cohenmichael said in Add number in each word by Notepad++:

Is it possible with Notepad++ ?

I tend to say no. Regex, normally, does not have a way to do
mathematical operations. From my point of view you need a scripting
language like PythonScript/LuaScript to do such operations.
If you want to go this way, let us know.

Cohenmichael

Thanks for your help.
What are the steps to follow for PythonScript?

Ekopalypse

This depends on which npp version you are using.
Can you post your debug info which is available from ? menu, the last menu item?
Or do you already have pythonscript installed?

Cohenmichael

Hi,

I just installed PythonScript on Notepad++ 7.6.4, 32 bit. It’s functional now !

What is the script to set up ?

Many thanks,

Cohenmichael

Version of PythonScript 1.3!

@Cohenmichael

What is the script to set up ?

Depends on your exact requirements.
Do you want to add a number on any word or just on hello?
A script might look like this.

from Npp import editor

def add_number(line_content, line_number, total_num_lines):
    words = line_content.split(' ')
    for i, word in enumerate(words):
        if word[0].isalpha():
            words[i] = '{}.{}'.format(i, word)
    editor.replaceWholeLine(line_number, ' '.join(words))

editor.forEachLine(add_number)

Steps to do:
Plugins->PythonScript->New Script
give it a meaningful name
copy and save script
Plugins->PythonScript->Configuration
put it into menu or toolbar
done

Cohenmichael

Thank you so much. It works well !

I want the script only for the word Hello.

I have several pages that contains this keyword, is it possible to make it automatic on all pages ?

Thanks again,

Ekopalypse

@Cohenmichael

so you would change, if not already done, to

if word == 'Hello':

is it possible to make it automatic on all pages

Means what?
You have all pages open in npp in different tabs?
Is a bunch of files in a directory?
Should be done when opening a file automatically?
You wanna execute a script which runs through the directory
and replaces it in each file when found?
Something else?

Cohenmichael

I made the change. The script is functional!

I have several files (.txt) in a folder. I could not execute the script automatically on all pages. Manually it works obviously!

How to run the script automatically on all pages?

Thanks a lot for your help

@Cohenmichael said in Add number in each word by Notepad++:

automatically

You need to explain what automatically in your case means.
There must be trigger to run the script but for which trigger
are you looking for?
Could you explain what you want to do? Like,
if I start npp and open file x I want to have result y
or
if I start the pc I want to have my coffee machine making me coffee
…
Do you get what I’m looking for?

Cohenmichael

Sorry if I was not clear.

I want to make a modification on all the words “Hello” existing on all pages name1.txt, name2.txt, … +100 document.txt

When I use Notepad ++, I open my folder contains all documents (.txt) by Folder as WorkSpace.

In this step, I don’t know what to do to change the word “Hello” on all pages automatically with this script.

Ekopalypse

Ok I see - not that easy - let me think about it.
As I’m leaving the office now I’m following up on this later this day,
unless someone else jumped in and provided a solution with fits your need.

Cohenmichael

Thanks a lot !

Cohenmichael

Hi,

I did a search on google, and I made a small modification on the script.

Notepad ++ opens all the pages of the folder, and the change is made only to the last document.txt and the rest is intact.

thank you

-----------The script------------

import os

os.chdir(‘C:\Users\yrkj\Desktop\allfiles’)
list_of_files = [x for x in os.listdir(‘.’) if x.endswith(‘.txt’)]
for file in list_of_files:
notepad.open(file)

from Npp import editor

def add_number(line_content, line_number, total_num_lines):
words = line_content.split(’ ')
for i, word in enumerate(words):
if word == ‘hello’:
words[i] = ‘{}.{}’.format(i, word)
editor.replaceWholeLine(line_number, ’ '.join(words))
notepad.getFiles()
editor.forEachLine(add_number)

notepad.save()
notepad.close()

Put your script in a code block using the </> “toolbar button” when composing. Python relies on indentation when defining blocks, so it is impossible to tell the true logic of your script the way you posted it.

Cohenmichael

I don’t know how to do that !
I don’t have any knowledge about programming scripts for Python, I just tried if it work but it didn’t work.
The published script is targeted only for Ekopalypse, maybe it has ideas to make it work.

You don’t know how to select some text in a post you are composing and press this button??:

Ye Gods, Man!

Sorry, I misunderstood your message.

    words = line_content.split(' ')
    for i, word in enumerate(words):
        if word == 'nounous':
            words[i] = '{}.{}'.format(i, word)
    editor.replaceWholeLine(line_number, ' '.join(words))

editor.forEachLine(add_number)
notepad.getFiles()

@Cohenmichael

do you see a need to open each file in notepad,
using editor instance to manipulate it
and then using notepad instance to save and close it?
It could be done with plain file read/write as well.

Test the script extensively before using it in production

Assumptions done by the following script is
Folder as workspace is visible
The word looking for is exactly Hello, not hello or HELLO …
Only the root directory is scanned for files having .txt extension, no recursion aka subdirectories are searched.

I tried 2 operations and the script didn’t work.

1st operation: I opened the folder content all documents (.txt) by Folder as WorkSpace, then I clicked execute the script and displayed this message:

Python 2.7.15 (v2.7.15:ca079a3ea3, Apr 30 2018, 16:22:17) [MSC v.1500 32 bit (Intel)]

Ready.
Traceback (most recent call last):

NameError: name 'h_systreeview32' is not defined

2nd operation :
I opened all documents (.txt) on Notepad++ and I ran the script, no change on all pages, and it didn’t display any message.
