Win32::Mechanize::NotepadPlusPlus - Automate the Windows application Notepad++


    use Win32::Mechanize::NotepadPlusPlus ':main';
    my $npp = notepad();    # main application


Automate the Windows application Notepad++. This is inspired by the Notepad++ plugin PythonScript, but I decided to automate the application from the outside, rather than from inside a Notepad++ plugin. But this module uses similar naming conventions and interface to the PythonScript plugin.


These give you access to the Notepad++ application GUI and the Scintilla editor components inside Notepad++. The main module exports functions that return the default instances.



Win32::Mechanize::NotepadPlusPlus::Notepad gives access to the actual Notepad++ application.

    my $npp = notepad();



Win32::Mechanize::NotepadPlusPlus::Editor gives access to the underlying Scintilla component(s) used to actually edit the text files in Notepad++.

In PythonScript, the default instance is called editor for the active editor window. There are two additional instances, editor1 and editor2 for accessing the specific "left" and "right" editor panes.

    my $left_pane = editor1();
    my $right_pane = editor2();
    if( editor() == $left_pane ) { ... }    # do this only if left pane is active pane

What About a Console Object?

The Console was a PythonScript feature, beacuse it had an embedded Python interpreter. Since Win32::Mechanize::NotepadPlusPlus is an outside-in framework, there is no Perl interpreter embedded in Notepad++.


By default, the module exports nothing.


Exports the "notepad", "editor", "editor1", and "editor2" functions.


Exports the variables from both Win32::Mechanize::NotepadPlusPlus::Notepad::Messages and Win32::Mechanize::NotepadPlusPlus::Editor::Messages

    use Win32::Mechanize::NotepadPlusPlus qw/:vars/;
    # from Editor::Messages: %SCIMSG, %SCINTILLANOTIFICATION, and more than 50 others.


This is the first public release of the module. In general, it works. As with all first releases, there is room for improvement; I welcome feedback.

The first known limitation is that none of the hooks for Scintilla or Notepad++ callbacks have been enabled. That may come sometime in the future.

All the testing and development was done with a US-English installation of Notepad++, and all the file encodings have been ANSI or UTF-8. I know that I need to include better tests for encoding, and any help you can provide with that is appreciated.

Notepad++ is a Windows application, so that's the intended platform for this module. However, I know Notepad++ can be made to run in Wine and similar environments in Linux, so it may be possible to make this module drive Notepad++ in such an environment. Feedback on this process is welcome.


To install this module, use your favorite CPAN client.

For a manual install, type the following:

    perl Makefile.PL
    make test
    make install

(On Windows machines, you may need to use "dmake" or "gmake" instead of "make", depending on your setup.)
