Anyone used the new v8.3.3 API calls yet?

Ekopalypse

It is looking for an external lexer like Vlang or Gedcom.

>>> SendMessage(notepad.hwnd, 1024+1000+104, 'VLang', 1)
1
>>> SendMessage(notepad.hwnd, 1024+1000+104, 'VLang', 2)
1
>>> SendMessage(notepad.hwnd, 1024+1000+104, 'perl', 2)
0
>>> SendMessage(notepad.hwnd, 1024+1000+104, 'Perl', 0)
0

@ekopalypse ,

That makes sense.

Unfortunately, I cannot get it to return 1 with the GEDCOM lexer (with "Gedcom" or "GEDCOM" as the language name; I can see GEDCOM in my Langauge menu), whether I do 1024+1000+104 from PythonScript (like you showed) or from external C++ or PerlScript. :-(

@peterjones

Strange, works for me.

import ctypes
ctypes.windll.user32.SendMessageW(notepad.hwnd, 1024+1000+104, 'GEDCOM', 2)

mode = ctypes.c_ssize_t(0)
ctypes.windll.user32.SendMessageW(notepad.hwnd, 1024+1000+103, 'GEDCOM', ctypes.pointer(mode))
mode.value

Ekopalypse

The name of the lexer seems to be case sensitive.

@ekopalypse ,

and to prove that otherwise, Notepad++/PythonScript can do message communication:

>>> winv = ctypes.windll.user32.SendMessageW(notepad.hwnd, 1024+1000+42,0,0)
>>> console.write("Win v{}\n".format(winv))
Win v14
>>> nppv = ctypes.windll.user32.SendMessageW(notepad.hwnd, 1024+1000+50,0,0)
>>> console.write("NPP v{}.{}\n".format(nppv>>16, nppv&0xFFFF))
NPP v8.33

I would be surprised if it’s Python 2.7.18 vs Python 3.8.5 (especially since I get the same 0s when I run from an external C++ program as well). But I’ll try that:

Weird… I would have expected the same results from PythonScript 2.0.0 as I got in PythonScript 3.0.12 alpha, since SendMessageW shouldn’t be significantly different between the two.

At least I have a known working setup, and can start comparing what C++ and/or Perl are sending, as compared to Python.

(Do you have notepad.hwnd set during your startup.py? Because I don’t have that attribute to the notepad object…)

Under Python 2, wouldn’t you want to pass u'GEDCOM' to SendMessageW, not 'GEDCOM' ?

Ekopalypse

It’s like Alan said.
With Python2 you have to use a Unicode string u'GEDCOM' if you want to use the W version of SendMessage.
Another way would be to use SendMessageA and 'GEDCOM'.
With Python3 it is the other way round: 'GEDCOM' is the Unicode version and you would have to use b'GEDCOM' if you want to use SendMessageA.

This is the main difference between python2 and python3.

Ekopalypse

Sorry, I forgot to answer your question.
Yes, notepad.hwnd is set by my startup.py.

notepad.hwnd = user32.FindWindowW('Notepad++', None)
editor1.hwnd = user32.FindWindowExW(notepad.hwnd, None, "Scintilla", None)
editor2.hwnd = user32.FindWindowExW(notepad.hwnd, editor1.hwnd, "Scintilla", None)
notepad.splitter_hwnd = user32.FindWindowExW(notepad.hwnd,
                                             None,
                                             'splitterContainer',
                                             None)

where user32 is

user32 = ctypes.WinDLL('user32')

Enjoy your holidays/vacation/days off …

More PS3 code, unless from __future__ import unicode_literals is at the top.

I don’t know, has everyone made the jump from PS2 to PS3, except me?

@alan-kilborn

I assume that most users use Python 2, as it is the default PythonScript version installed via the plugin admin.

We dumped Python2 back in December 2019 right before it was sunsetted. A few months of migration prior and then all new scripts were Python3. Since Python3 is the only Python installed on my Windows system, I first started with PythonScript 3.0.7-alpha (since it matched my Python 3.8 version) and I haven’t changed since.

Cheers.

Note that I said:

which is NOT equivalent to:

“has everyone made the jump from Python2 to Python3, except me?”

The jump to Python3 for all purposes other than N++ scripting was made long ago.

Agreed. I didn’t explain in detail enough, sorry.

Since I’m coding in Python3 and my goal to install PythonScript was to get some Language Server / IDE-like features when coding Python, I needed to run PythonScript 3 so my parsing libraries (Jedi, Rope, PyFlakes) are installed in my system Python3 and will parse Python3 code and PythonScript 3 will find them and execute them.

Cheers.

If you put the same effort into your day job as you do here in the Community and also on the N++ user manual, a resounding “WELL DESERVED!” :-)

@alan-kilborn & @Ekopalypse ,

After getting back from the coast, I confirmed that

import ctypes
notepad.hwnd = ctypes.windll.user32.FindWindowW(u'Notepad++', None)
nppv = ctypes.windll.user32.SendMessageW(notepad.hwnd, 1024+1000+50,0,0)
console.write("NPP v{}.{}\n".format(nppv>>16, nppv&0xFFFF))
ctypes.windll.user32.SendMessageW(notepad.hwnd, 1024+1000+104, u'GEDCOM', 2)
mode = ctypes.c_ssize_t(0)
ctypes.windll.user32.SendMessageW(notepad.hwnd, 1024+1000+103, u'GEDCOM', ctypes.pointer(mode))
mode.value

did what I wanted in old PythonScript, so it was a matter of the missing unicode marker. Which probably means that the reason my compiled version failed was probably that it wasn’t in UTF-16-LE like it should have been. But it gives me a lead, and I know in my PerlScript source code what I need to do to make sure that I send the string as UTF-16-LE.
