pythonscript: any ready pyscript to replace one huge set of regex/ phrases with others?

Alan Kilborn

SEARCH \w+

REPLACE \u$0

AFAIK, they do not modify anything, ( I mean regarding case of characters ! ) when executed from a Python script :-((

Interesting. I noticed that the following variant on that above WILL work to affect case when using editor.rereplace() in a script:

Find: (\w+)
Repl: \U\1

It seems like either variant should capitalize all lowercase letters in a document. HOWEVER, only the script version does this! When run interactively with the Replace dialog in Notepad++, these 2 variants only capitalize the first letter of every “word”.

Can anyone offer an explanation for:

why Guy’s original regex replace does nothing in the script
why both of these regex replaces only change to uppercase the first letter of every “word” when run with N++ interactive replace (but – and I think act correctly in the script)

Let me correct this:

why both of these regex replaces only change to uppercase the first letter of every “word” when run with N++ interactive replace (but the one that involves capturing group #1 and using \1 in the replace part – acts correctly in the script, at least I think it does)

Hmm, better but maybe still not a great way of expressing it. :-P

If I understand you correctly, I’m totally lost - my setup must have some kind of builtin wizard as
I do get different result. So just to clarify, having the text this is some text and aiming to get
THIS IS SOME TEXT we would use \w+ and replace with \U$0 or (\w+) with \U$1 as replacement.
For me, both work the same in the dialog and none work when called like editor.rereplace('\w+','\U$0') from a script.
But you do have a different result?

Alan Kilborn

@Eko-palypse

Wow. WOW. I find I cannot reproduce my earlier results. It seems to be working consistently now (duplicating your results). I guess I have egg on my face and sorry for the false alarm; unless it takes some sort of special sequence of actions to get into a weird mode! I did restart N++ an hour ago so I supposed that is a possible occurrence.

One thing I am seeing now that the editor.rereplace() is doing “nothing”:

I use the LocationNavigate plugin for its ability to specially mark changed lines (wish there was a better/more-current solution to that, btw!). When I run the scripted replace, although visually no text changes, the plugin does mark every line where \w+ matches. Basically this means all lines besides empty ones got “changed”. So…not really sure what under-the-hood voodoo magic is happening when using \U (and probably others like it) with a scripted replace, but it sure seems like SOMETHING interesting might be happening. If what is happening is that the \U is being ignored and abc is simply being replaced by abc perhaps that is not all that interesting. :(

:-) … live is interesting, isn’t it … what is true now might be false in the next minute :-)

From modify callback I see that there is a replace but it just ignores the \U

Since you pointed out that the Pythonscript editor.rereplace() way of working has some distinct advantages (less bugs?) over the Notepad++ interactive Replace dialog, how about a little script for making testing the differences even easier (and less cryptic than typing a one-liner in the PS console):

if editor.getSelectionEmpty():
    p1 = editor.getCurrentPos()
    p2 = editor.getTextLength() - 1
else:
    p1 = editor.getSelectionStart()
    p2 = editor.getSelectionEnd()
s = notepad.prompt('Enter search regex:', '', '')
if s != None and len(s) > 0:
    r = notepad.prompt('Enter replace regex:', '', '')
    if r != None:
        editor.beginUndoAction()
        editor.rereplace(s, r, 0, p1, p2)
        editor.endUndoAction()

If a selection is active when running the script, it acts like N++'s “Replace All…with In Selection ticked”. Otherwise, it acts like a normal N++'s “Replace All” acting on text from caret downward to EOF.

Not rocket science, but then again neither was the original script way above. :)

how can I download all script at bruderstein/PythonScript/scripts/Samples/ as a single zip file?

Thanks.

@V-S-Rawat

how can I download all script at bruderstein/PythonScript/scripts/Samples/ as a single zip file?

you can do that by either downloading the whole master repo from >>> here <<< and extract PythonScript/scripts/Samples/,

… or by downloading them manually one by one, then package them into another zip and commit this zip to david @bruderstein , with the request for publishing, so that you can re-download it 😉

Eko palypse

… or by writing a python script doing it
@V-S-Rawat I leave the implementation of the compressing function to you ;-)

import urllib
import re

sample_url = "https://github.com/bruderstein/PythonScript/tree/master/scripts/Samples"
raw_url = "https://raw.githubusercontent.com/bruderstein/PythonScript/master/scripts/Samples/"
save_dir = r'D:\xyz\{}'

_f = urllib.urlopen(sample_url)
data = _f.read()
links = re.findall('href="(.*?\.py)"', data)
for link in links:
    file = link.rpartition('/')[2]
    urllib.urlretrieve(raw_url + file, save_dir.format(urllib.unquote(file)))

This script will run from within npp and will access net and download all *.py on that page?

Quite powerful. I never thought such a thing is even possible.

:-)

Thanks.

@V-S-Rawat

Yes, but since it does not use any Notepad ++ objects, it can also be run outside of npp.
The ecosystem of Python is really and I mean really huge.
If you are thinking about a problem and how you can solve it, there is most likely already a Python module available that is made for it.
The only little downer is that PythonScript has not implemented pip or it can not be easily implemented (as far as I understand it), which means you have to, if you want to rely on external modules, do some manual work to make it happen within pythonscript plugin.

V S Rawat

That brings another bouncer to me.

You mean same npp pyscript can be run from outside of npp?

how? I only have pyscript plugin installed, and it seems it had installed a huge set of files. Are those files sufficient to run npp pyscript from outside npp? How? which exe file to run?

or do I have to download python afresh and install that to be able to run python out of npp?

And if so, can I think remove pyscript plugin and still be able to run pyscript from within npp?
because that would mean one python installed by pyscript within npp, and another python installed directly in programfiles. Why keep both, there may be version clashes between them.

The ecosystem of Python is really and I mean really huge.

yeah, I was also thinking that across the years that python has been popular and widely used, a huge repository of pyscripts must already have been made. But I find very less repositories very less number of scripts then I thought should have been there. Seems I didn’t not reach major pyscript repositories.

Thanks.

Eko palypse

@V-S-Rawat

Yes, this particular script may run outside npp if you have a local
python installation and then by calling python scriptname.py

Theoretically, you can also uninstall the plugin and remote control
npp and scintilla with the local python installation.
But then you have to program everything yourself
what the pythonscript plugin otherwise provides to you.
The callbacks could be a bigger challenge.

A central repo for scripts does not exist, as far as I know,
but a central system for installing modules does.

Alan Kilborn

@V-S-Rawat

Just to say a bit more, adding onto what Eko said:

If you have Pythonscript installed with N++, it is run from a python.dll. If you have no other external Python installed (which would be a python.exe file and of course everything that goes along with it) then you cannot run a .py file outside of N++, even if that .py file isn’t using anything related to N++ (e.g. editor. and notepad. object function calls). Conversely, as pointed out above, you can run such a .py file from inside N++.

@guy038 I’m getting this following error when I try to run this script.

@Mayonnaisu

If you get an error message like ValueError: too many values to unpack, then this is a strong indication that you have generated too many values :-) - I mean, what is wrong with this message?
Consider the following: “(a, b) = ‘A B C’.split()”
From the code, you expect the split to generate TWO results that you want to put into variables a and b, but that’s not the case, is it?
So your real data does not match your code logic.

Mayonnaisu

@Ekopalypse
I see that’s how it is. So I just need to delete the (third) variable that I don’t need. Thanks for the information!

Ekopalypse

@Mayonnaisu

The error message indicates that you need more variables.
If you need less, then the error message would be slightly different, something like need more than 2 values to unpack.
