PythonScript 2.0

Ekopalypse · Apr 9, 2019, 9:00 PM

As I’m afraid that the PythonScript project won’t really be maintained, I’m thinking about creating a new PythonScript plugin.
Since my knowledge of C/C++ is not very good and Boost brings further challenges, I was thinking about using either pybind11, pyo3, cython or cffi.
Now to the question: Does anyone already know one of the above and knows that it can be used or not?

@Ekopalypse

now this is a catchy title 😂😂😂

for your afraidness: i’m not aware that @chcg has ceased development on that.
who knows, maybe you could join in the future.

@Meta-Chuh

I don’t know - I’m not really eager to learn C++ in depth. The little I need to know
by using one of the others mentioned might work but for the existing project there
is a lot of c++, boost and cpython knowledge needed to move it forward, especially
since there are a couple of changes in python3 api as well.

The existing Pythonscript plugin is an awesome piece of work. It sure seems like it is worth it for it to continue living on in its current incarnation.

chcg · Apr 12, 2019, 5:36 PM

Hi, I’m still maintaining pythonscript, but at a rather low rate. Unfortunately @Claudia-Frank left N++, so a big part of contributions is missing. Currently the probably biggest blocker is the compatibility with the new plugin structure required for N++ 7.6.x and PluginAdmin to search/find the python.dll within the plugin dir, see https://github.com/bruderstein/PythonScript/issues/109

Additionally the next step would be https://github.com/bruderstein/PythonScript/issues/36
with initial work ar https://github.com/chcg/PythonScript/tree/python36_test

And additionally get the webpage corrected https://github.com/bruderstein/PythonScript/issues/113

hi @chcg

Currently the probably biggest blocker is the compatibility with the new plugin structure required for N++ 7.6.x and PluginAdmin to search/find the python.dll within the plugin dir

a very, very theoretical quick and dirty plugins admin single target deployment solution for pythonscript, could be:

deploy all files, including python.dll, to plugins\PythonScript as single folder target.
the plugin itself then checks for existence of instDir\python.dll at every startup.
if instDir\python.dll does not exist and notepad++ is not elevated, show an alert popup: “Please restart Notepad++ in Administrator mode, to initialise PythonScript.”
if instDir\python.dll does not exist and notepad++ runs elevated, copy plugins\PythonScript\python.dll to instDir\python.dll, and make an alert: “PythonScript initialisation complete. Please restart Notepad++ for the changes to take effect.”

@chcg

thx for all the work you’ve and other have done to keep this alive.
I’m very much enjoying this plugin.
Concerning the open issues, at least the second part, custom dialogs,
could be ignored when including pywin32 into PythonScript.

Alan Kilborn · Apr 17, 2019, 5:32 PM

@Ekopalypse

custom dialogs…could be ignored when including pywin32 into PythonScript.

In PS, I do some basic UI stuff that is missing from PS with the techniques shown here:

http://www.averdevelopment.com/python/EasyDialogs.html

Granted these are simple standard dialogs, but they fill gap.

Of course I think the custom dialogs mentioned would be a little different, but I thought I’d share my way of doing File Open, Save etc dialogs in PS when needed.

Ekopalypse · Apr 17, 2019, 6:27 PM

@Alan-Kilborn

thank you, didn’t know about this site.
pywin32 advantage is not only the easy to build uis but although the already defined win api functions.
No need to check and see which function/structure needs to be create how but
have to admit, that the usage of a few functions is a little bit different to what msdn states.

I think the custom dialogs mentioned would be a little different,

For example

Alan Kilborn · Apr 17, 2019, 7:11 PM

@Ekopalypse

Yea, I believe I tried pywin32 at some point and found it strange.

chcg · Apr 17, 2019, 7:18 PM

Example for ctypes:
https://github.com/bruderstein/PythonScript/blob/master/scripts/Samples/ReplaceDefaultReplaceDialog.py

Currently already available is https://github.com/bruderstein/PythonScript/releases/download/v1.3.0/PythonScript_TclTk_1.3.0.0.zip
, see https://github.com/bruderstein/PythonScript/blob/master/scripts/Samples/Sorter.py

Alan Kilborn · Apr 17, 2019, 7:35 PM

@chcg

Yea…except that Tk sucks. :(

In fact, most Python GUIs except PyQt and wxPython (or whatever it is called now) are so bad they aren’t useful. My opinions only, people, don’t go nuts on me.

Ekopalypse · Apr 17, 2019, 7:39 PM

@chcg

you are absolutely right and I would say, there is a MUST DO READ those samples
for everyone starting investing pythonscript plugin as it nearly covers any aspect of
manipulating either notepad++ or scintilla or how to extend npp - as far as I can see.

But using ctypes is … uncomfortable, as you have to declare every piece,
with the risk of making it wrong. pywin32 did this already for you and Tk is a different beast.
I haven’t found out how one can create a Tk UI which can be docked.
Please don’t get me wrong - not having pywin32 isn’t a showstopper at all - it is just convenient.
And, at any time, one could install a local python and replace the python dll with the one of the local installation and can benefit from pip.

Alan Kilborn · Apr 17, 2019, 7:45 PM

@Ekopalypse

You mean like this stuff is “uncomfortable” when doing ctypes?:

        self.WNDENUMPROC = ctypes.WINFUNCTYPE(BOOL, HWND, LPARAM)
        self.FindWindow = ctypes.windll.user32.FindWindowW
        self.EnumChildWindows = ctypes.windll.user32.EnumChildWindows
        self.GetClassName = ctypes.windll.user32.GetClassNameW
        self.GetWindowText = ctypes.windll.user32.GetWindowTextW
        self.GetWindowTextLength = ctypes.windll.user32.GetWindowTextLengthW
        self.SetWindowText = ctypes.windll.user32.SetWindowTextW
        self.GetACP = ctypes.windll.kernel32.GetACP
        self.create_unicode_buffer = ctypes.create_unicode_buffer

It really isn’t that bad, once you get some boilerplate (word of the day!) worked up. :)

@Ekopalypse

Even that isn’t that bad (all in a separate file that is imported), but I admit it will get a bit tedious when posting scripts here and just going to get the ones needed for the scripts. But overall I find ctypes an amazing thing. And the things that you can use it for in a PS under Notepad++…also amazing. :)

But some of the constructs get pretty tricky. I’ve used nulledge to find examples I need.

Ekopalypse · Apr 17, 2019, 8:02 PM

@Alan-Kilborn

… and just going to get the ones needed for the scripts …

at the end that’s exactly where it is handy to have it already defined.
Of course, now that I have made it, I can use it but if I want to post a script which
would use it, it isn’t that easy anymore as I might have to undo some parts to make it work …

But some of the constructs get pretty tricky. I’ve used nulledge to find examples I need.

To be honest, if I don’t understand how it should work I’m looking for VB6 examples :-)
Most of the time those can be used just by converting and using the right python syntax.

chcg · Apr 17, 2019, 8:05 PM

So if you have some example scripts worth sharing guys you could create a PR at pythonscript and I will merge them.

Alan Kilborn · Apr 17, 2019, 8:05 PM

@Ekopalypse

The beauty of the code on nulledge is that it is already in Python. But oops, it appears that nulledge has gone 404. :( Maybe my future needs will have VB6 searches involved.
