Perl subroutine calltips - with PythonScript

5 lines of pythonscript might give you an embedded perl.

Oh, the irony. :-)

Ekopalypse

:-D

this seems to do something, not sure what but it doesn’t crash my npp … so … still crossing fingers ;-)

from ctypes import CDLL, POINTER, c_int, c_char_p

perllib = CDLL(r'd:\perl\bin\perl531.dll')

["-le", "print 'something \"with\" quotes';"]

perllib.RunPerl.restype = c_int
perllib.RunPerl.argtypes = c_int, POINTER(c_char_p), POINTER(c_char_p)
args = (c_char_p * 2)(b"-le", b"print 'something \"with\" quotes';")
print(perllib.RunPerl(len(args),args, None))

@PeterJones

can you give me a qiuck “Win32::Mechanize::NotepadPlusPlus for dummies äh ekopalypses” to open a new npp buffer?

PeterJones

@Ekopalypse ,

From the command line, to just open a new file tab:

perl -le "use Win32::Mechanize::NotepadPlusPlus qw/:main/; notepad->newFile();"

If you want to call a script.pl instead,

use Win32::Mechanize::NotepadPlusPlus qw/:main/; 
notepad->newFile();

But that assumes that perl has the right @INC (include library paths) to find Win32::Mechanize::NotepadPlusPlus.

@PeterJones

D:\perl\bin>perl D:\temp\perl\Win32-Mechanize-NotepadPlusPlus-0.005\Makefile.PL
Could not open 'lib/Win32/Mechanize/NotepadPlusPlus.pm': No such file or directory at D:/perl/lib/ExtUtils/MM_Unix.pm line 2973.

Now you know why I said “… for ekopalypses” ;-)

Ekopalypse

hah, it is the other way around … from within the source call perl …

For the installation, you need to be in the D:\temp\perl\Win32-Mechanize-NotepadPlusPlus-0.005\ directory, and run d:\perl\bin\perl Makefile.PL instead: you need to be in the same directory as the Makefile.PL, so that the relative paths are all correct.

and then I used nmake to create the pm’s.
I’ve copied the resulting Win32 to …/perl/lib/
but now I get Can't locate Win32/API.pm in @INC (you may need to install the Win32::API module) (@INC contains: d:/perl/site/lib d:/perl/lib) at d:/perl/lib/Win32/Mechanize/NotepadPlusPlus/Notepad.pm line 9.

@Ekopalypse ,

The other thing I realized: you probably won’t have all the prerequisite modules installed. I normally use the cpanm utility, which distributes with strawberry perl, and that automatically downloads and installs prereqs before the module you’re trying to install. Without such a tool (and if you built your own perl, which I think you did to get the DLL), I don’t know that you have that.

I think the make process will tell you what prereqs you’re missing … but it’s been a long time since I’ve done a complicated manual install of a module.

Oh, yep, there, you posted the error while I was typing. You’re going to have to install at least Win32::API first… doing that manually is a pain.

When you built your own perl, did you at least get cpan, if not cpanm? I think one or both would be in the same directory as perl.exe… if you have cpanm, just do cpanm Win32::Mechanize::NotepadPlusPlus, and everything should work. If you have just cpan, I forget whether it handles prereqs; try cpan Win32::Mechanize::NotepadPlusPlus; if that’s not sufficient, do the missing prereqs one at a time with the cpan client. If you have neither… um… That’s going to be tough.

I believe it does - I normally just use CPAN and it fetches what I need to build.

Cheers.

Ekopalypse

I have cpan and it keeps installing stuff - did I choose to install the world??

Ekopalypse

it does this now since ~10 minutes

Ekopalypse

finished - but no Win32::API. started cpan Win32::API now.

Is there a reason you build your own Perl? I have Strawberry 5.24 installed and doing this works:

That’s @Ekopalypse script from above using my “system” Strawberry Perl 5.24 DLL (the Perl that has my Win32::Mechanize::NotepadPlusPlus and all my other stull installed on it). Not sure why it’s printing “9” in the PythonScript console - is that what it’s supposed to do? I thought I’d get that string "print something ...

Cheers.

Ekopalypse

@Michael-Vincent

I get also 9 and from the function it seems correct to return an int.
See my previous post. RunPerl returns only an int. Not sure how to get the result (the print output), so far.

Oh, OK - great then. Seems I may be able to keep testing along without having to build a Perl and just use my Strawberry install.

Cheers.

Ekopalypse

@Michael-Vincent

My Win32::API has been built but not installed because of failing tests I guess. Can you try the "use Win32::Mechanize::NotepadPlusPlus qw/:main/; notepad->newFile();" and see what happens?

Can you try

from ctypes import CDLL, POINTER, c_int, c_char_p

perllib = CDLL(r'C:\Strawberry\perl\bin\perl524.dll')

["-le", "use Win32::Mechanize::NotepadPlusPlus qw/:main/; notepad->newFile();"]

perllib.RunPerl.restype = c_int
perllib.RunPerl.argtypes = c_int, POINTER(c_char_p), POINTER(c_char_p)
args = (c_char_p * 2)(b"-le", b"use Win32::Mechanize::NotepadPlusPlus qw/:main/; notepad->newFile();")
print(perllib.RunPerl(len(args),args, None))

It just prints 9 in the PythonScript console. No new tab is opened. If I run the command itself from a prompt:

C:\ > perl -e "use Win32::Mechanize::NotepadPlusPlus qw/:main/; notepad->newFile();"

I get a new tab in Notepad++ as expected.

At least if it printed 42 we’d know we’re on to something …

Cheers.

Ekopalypse

Ja, 42 would be nice :-)
So 9 seems to be an error code.
