Adding Libraries to PythonScript Plugin

@michael-vincent Hey I’ve been doing some testing in PyCharm and noticed something strange. I’ve imported pandas and Npp like so:
If I hover over that statement in PyCharm it says:
No documentation found.

Do you happen to have any idea why this might be? The documentation shows that same import supporting the sort_values function so I’m not sure what the issue is. Please let me know if you can think of anything, thank you!

sort_values currently has no doc-string. PyCharm would inspect sort_values and finds no documentation. A comment is in the source # TODO: Just move the sort_values doc here.

Please focus mainly on Notepad++ and PythonScript. This topic is getting very broad if PyCharm issues are included.

WHY?!?!?!

The Npp library won’t work in PyCharm and If you’re trying to manipulate CSV files as I thought you were and not doing it in Notepad++, why are we even talking about Notepad++ and PythonScript. You can easily open files from disk in Python without going through Notepad++ if you’re not even using it.

BUT if I try to use the “sort_values” function, nothing happens:

sorted_file = file.sort_values(by=[“Name”], ascending=False, inplace=True)

No kidding - you didn’t do anything to the file in Notepad++, you just tried to sort the file on disk by opening it by name, not referencing the content of the file in the Notepad++ Scintilla editing component by some method of the editor instance.

If you want to actually sort the file in Notepad++ (and ultimately the one on disk), you need to read the content of the editor object , sort it and write it back.

Maybe have a look at those example scripts that came with PythonScript. Run them. See how they work. Try modifying them a bit to make them do something else before diving headfirst into full file manipulation with pandas.

And please for heavens sake backup all of your data before going any further. I fear this won’t end well.

Cheers.

I was only using PyCharm for syntax highlighting and intellisense I know that the Npp library doesn’t work there. I am trying to edit the CSV files in Notepad++

That is what I am trying to do, shouldn’t this line be reading the filename via Notepad. and reading the CSV using read_csv?

file = pandasForSortingCSV.read_csv(notepad.getCurrentFilename())

Where is that comment and where can I access the sort_values doc? Shouldn’t this have been done upon installation of pandas?

Nobody here is going to comment on what Pandas’ read_csv function is going to do, because, like a lot of your questions, it is OFF-TOPIC for this forum.

Something on-topic:

Typically with PythonScripting, you want to act on the live text inside a Notepad++ editing tab. You don’t want to be dealing with files in the OS, if you can avoid it. If you manipulate the disk file, you will get a popup to the effect of “file on disk has changed – do you want to reload it?”, making for an awkward user experience with your script.

More OFF-TOPIC stuff.
Please try to confine discussed issues to on-topic things.

That is what I am trying to do, I suppose the bet way would be to get all of the text in the currently open file using the editor object somehow…

@john-doe-1,

We cannot help with Pandas-specific questions. But the phrasing and example code shows you don’t understand the PythonScript plugin interface yet, nor the difference between a file on disk and the file that’s open in Notepad++.

When Notepad++ opens a file, it reads the contents from disk, and stores it in memory. When you edit the file in Notepad++, you are editing the file in memory until you (or some automated task) saves.

You said,

That is what I am trying to do, shouldn’t this line be reading the filename via Notepad. and reading the CSV using read_csv?
file = pandasForSortingCSV.read_csv(notepad.getCurrentFilename())

No. That is looking up the name of the file that is currently open in Notepad++, and passing that filename as an argument to a Pandas command. Presumably, the Pandas command separately reads the file based on its filename from disk; it will not read the contents from the file that’s open in Notepad++. So if you had edited-but-not-saved in Notepad++, Pandas will read whatever’s on disk, not what’s open in the Notepad++ window.

While I was typing this reply, Alan and you had a back and forth, in which you said,

I suppose the bet way would be to get all of the text in the currently open file using the editor object somehow…

That’s what I was working toward. editor.getText() will give you the entire contents of the currently-active editor tab as a string.

If there is a version of the Pandas.read_csv or similar command that will accept a string that contains the contents of the CSV, instead of a filename, then you can send the that string to the function… pandasForSortingCSV.read_csv_from_string(editor.getText()) . (Please understand, I am not saying that read_csv_from_string exists… I am using that as a dummy function; you will have to learn enough Pandas to know how to read a CSV from a string instead of from a file name. We cannot help you with Pandas here)

Well, that “somehow” is probably all_text = editor.getText(). :-)

It’s a basic concept, but it is on-topic, so it is all good. :-)

Well, I could as I am very familiar with Pandas…but I refuse to help with it here. :-)

Understandable, if you can point me to a more specific forum for Pandas I’d appreciate it. Thanks for your help so far.

Hmm, can’t say I’ve ever used one.
I searched it up; apparently a “more important” pandas is a medical condition. And of course the cute bears…

But I did find this one, no idea of its quality: https://community.developers.refinitiv.com/tags/pandas.html

I’m sure some more intensive searching will provide others.
