PythonScript 2.0

Meta Chuh

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.”

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.

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.

@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

@Ekopalypse

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

Example for ctypes:

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

@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

@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

@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. :)

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.

@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

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

Alan Kilborn

@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.
