Integration of a script writen in Python

[Alan Kilborn]

@tho-gru

I must analyze the whole text to decide if the cursor is with a clickable link and extract the clickable link. I wonder if there is a more elegant solution because I assume that using regular expressions on the whole editor text within python script consumes a lot of computer resources.

I am not sure if there is a more efficient solution in general. Is there a possibility to register a Python script on a double click ( perhaps only for clickable links) and get the value of the link as parameter.

This really seems to be thinking about the problem the wrong way.
Notepad++'s Scintilla control has a mechanism to obtain “linked text”, so really it seems like that should be used instead of a brute-force mechanism as hinted at above.

I took a look at the “issue 10071” you linked.
The suggestion there was to tie it to a single-click of the mouse while the Alt key is held down.

So let’s do that; here’s a demo script that I call UrlAltClick.py:

# -*- coding: utf-8 -*-

from __future__ import print_function
from Npp import editor, SCINTILLANOTIFICATION, notepad

class UAC(object):

    def __init__(self):
        self.URL_INDIC = 8  # URL_INDIC is used in N++ source code
        self.ALT_MODIFIER = 4
        self.alt_held_at_click = False
        self.installed = False
        self.install()

    def install(self):
        if not self.installed:
            # https://www.scintilla.org/ScintillaDoc.html#SCN_INDICATORCLICK
            editor.callback(self.indicator_click_callback, [SCINTILLANOTIFICATION.INDICATORCLICK])
            # https://www.scintilla.org/ScintillaDoc.html#SCN_INDICATORRELEASE
            editor.callback(self.indicator_release_callback, [SCINTILLANOTIFICATION.INDICATORRELEASE])
            self.installed = True

    def uninstall(self):
        if self.installed:
            editor.clearCallbacks(self.indicator_click_callback)
            editor.clearCallbacks(self.indicator_release_callback)
            self.installed = False

    def is_installed(self):
        return self.installed

    def get_indicator_range(self, indic_number):
        # similar to ScintillaEditView::getIndicatorRange() in N++ source
        # https://github.com/notepad-plus-plus/notepad-plus-plus/blob/8f38707d33d869a5b8f5014dbb18619b166486a0/PowerEditor/src/ScitillaComponent/ScintillaEditView.h#L562
        curr_pos = editor.getCurrentPos()
        indic_mask = editor.indicatorAllOnFor(curr_pos)
        if (indic_mask & (1 << indic_number)) != 0:
            start_pos = editor.indicatorStart(indic_number, curr_pos)
            end_pos = editor.indicatorEnd(indic_number, curr_pos)
            if curr_pos >= start_pos and curr_pos <= end_pos:
                return (start_pos, end_pos)
        return (0, 0)

    def indicator_click_callback(self, args):
        # example: INDICATORCLICK: {'position': 12294, 'idFrom': 0, 'modifiers': 4, 'code': 2023, 'hwndFrom': 1577146}
        print('UriIndicatorAltClick indicator click callback')
        self.alt_held_at_click = (args['modifiers'] & self.ALT_MODIFIER) != 0

    def indicator_release_callback(self, args):
        # example: INDICATORRELEASE: {'position': 12294, 'idFrom': 0, 'modifiers': 0, 'code': 2024, 'hwndFrom': 1577146}
        print('UriIndicatorAltClick indicator release callback')
        if not self.alt_held_at_click: return
        self.alt_held_at_click = False
        (start_pos, end_pos) = self.get_indicator_range(self.URL_INDIC)
        if start_pos == end_pos:  return  # if click on indicator that is not URL_INDIC
        uri_text = editor.getTextRange(start_pos, end_pos)
        notepad.messageBox(uri_text, '')

if __name__ == '__main__':

    if 'uac' not in globals():
        uac = UAC()  # will automatically "install" it
    else:
        # each running the script toggles install/uninstall:
        uac.uninstall() if uac.is_installed() else uac.install()
        print('uac installed?:', uac.is_installed())

Running the script and then holding down the Alt key while clicking on the first link that appears in its source code (line 17 or so), one obtains this popup box:

That shows that it is very possible to easily obtain “underlined” text in a Notepad++ tab.
Instead of a simple message box, you can use the contents of the uri_text variable and do whatever you want with it.

@PeterJones said in Integration of a script writen in Python:

Giving proper attribution

Hmm, appears to me to “just be code”.
Anyone could have written that.

My scripts look a ton like Scott’s and Claudia’s code, and now even Eko’s code.
How come? Because I “grew up” with PythonScripting by emulating them and their postings here, now so long ago.
If I had to “attribute” them, whew!, I’ve got so many “stolen” snippets…
:-)

Anyway, Peter, if they even saw you using some sections of what they wrote, without attribution, I’m sure they wouldn’t think anything of it.

@PeterJones I gave it a try, but approach of @Alan-Kilborn looks to be nicer.
@Alan-Kilborn thanks for your helpful answer.

I end up with the following python code:

Now I am lokking for a “good” solution of executing scripts during startup. My first idea is like this:

import os

class UserScript(object):

    def __init__(self):
        self.pluginConfigDir = notepad.getPluginConfigDir()
        self.userScripDir = os.path.join(self.pluginConfigDir, "PythonScript", "scripts")

    def execute(self, scriptName):
        script = os.path.join(self.userScripDir, scriptName + '.py')
        exec(open(script).read())


if __name__ == '__main__':
    userScripts = [ "TgrUrlAltClick" ]
    for script in userScripts:
        UserScript().execute(script)

In future I want simply add script names in the userScripts variable like [ “TgrUrlAltClick”, “NewPythonScript” ].

Unfortunately this idea is currently not working. It ends with the following error messages:

Python 2.7.18 (v2.7.18:8d21aa21f2, Apr 20 2020, 13:25:05) [MSC v.1500 64 bit (AMD64)]

Ready.
Traceback (most recent call last):

I do not understand why datetime is not defined although I imported it in TgrUrlAltClick.py.

@tho-gru said in Integration of a script writen in Python:

Now I am lokking for a “good” solution of executing scripts during startup.

There’s an existing file called startup.py in PythonScript.
To run my demo script from above automatically on startup, you could do something like this; add these lines to startup.py :

import UrlAltClick
UrlAltClick.UAC()

[tho-gru]

@Alan-Kilborn thanks for your hint.

In startup.py I entered

import TgrUrlAltClick
TgrUrlAltClick.UAC()

This works a little bit:

1. The script TgrUrlAltClick.py is looaded
2. The Python Console does not open on startup although self.debug is still True
3. ALT-click works for links that are not matched, the Windows standard works fine in this case.
4. ALT-click for links matching the regular expression get the following error message

20210626-190826.832000 UriIndicatorAltClick indicator click callback
20210626-190826.832000 file:///C:\tmp\anchor-test-file.shtm#part3

I did not expect that automatic starting of a python script which is working when started manually causes so many problems.

Well, I certainly don’t claim to be an expert on the console instance.
In fact, I don’t know anything about it at all.
All I do in my scripts in the Console window is output debugging info with print() function calls.
So…what I’m saying is that I don’t know how to help you resolve errors relating to this.
Maybe someone else with some knowledge can chime in?

But I will point out that my demo didn’t introduce such console manipulations, your modifications must have. At which point, I turn it fully over to you to debug. :-)

I will say that console.run() seems a strange call to me to launch a browser. How about using ShellExecute or subprocess.Popen for this purpose? Probably the subprocess stuff gives you better control over exactly what you want/need to run.

@tho-gru said in Integration of a script writen in Python:

The Python Console does not open on startup although self.debug is still True

Did you notice the error message that your output showed? Specifically, it said

NameError: global name 'console' is not defined

If console is not defined, how do you expect console.show() to work?

Looking in your imports in the first script that you shared, you have the line:

from Npp import editor, SCINTILLANOTIFICATION, notepad

Notice that you don’t ever import the console symbol from Npp. You probably need to use:

from Npp import editor, SCINTILLANOTIFICATION, notepad, console

[tho-gru]

@PeterJones thanks for clarification. That makes sense.

I am wondering why this Python script works when executed via the menu (Plugins -> Python Script -> Scripts -> TgrUrlAltClick). If the console module was reported as missing during my tests when I started the script via the menu I might have fixed it before working on the startup.py. So I assume that the loaded modules differs for scripts started from startup and scripts started via the menu. How to inform the plugin developer about this issue?

@Alan-Kilborn thanks for the hint of using subprocess.call. I use it now.

Finally I got everything working. TgrUrlAltClick.py looks like:

And startup.py is:

import TgrUrlAltClick
TgrUrlAltClick.UAC()

As this was my first real python project I am pretty sure to use python more often.

@tho-gru said in Integration of a script writen in Python:

So I assume that the loaded modules differs for scripts started from startup and scripts started via the menu. How to inform the plugin developer about this issue?

TBH, I have never myself noticed any problem along these lines.
But if you want to create an issue concerning it, the PythonScript plugin website is: https://github.com/bruderstein/PythonScript

[Alan Kilborn]

This thread reminds me of an older discussion by @mkupper that I wanted to follow up on at some point.
That older discussion was HERE.

A recent version of Notepad++ (not sure which one – maybe the one the above link mentions) added the ability to do “custom links” via this setting:

To my knowledge, before this there has never been a great way to add a link in a N++ document that, when activated, will open another document into N++.
Sure, one could use file:// but then that would depend upon having a filepath in the link that is associated with Notepad++.
But…I’m not big on making N++ associations in the OS.

So, what I have set up allows me to put text like this in a document:

and when I activate this link, the intended file opens in Notepad++.
Obviously this required the addition of edit: to the URI customized schemes: box.

I’ve also set up Excel documents to be activatable the same way (but of course opening in Excel, not N++):

Often the files I have to use at work (shared files on a network drive) have spaces in their paths, e.g. W:\test\my Excel file.xlsx

This causes my link scheme to break down:

:-(

But that is a fairly simple thing to fix by doing this to the link text:

and having a macro that takes selected text (the real path, with spaces) in N++ and replaces spaces with %20 and then using the modified version in the edit: link.
Actually the macro does the prepending of the edit: text as well.

So, anyway, just showing an additional possibility (for scripting), a bit above and beyond what the OP wanted to do with linked text in this thread.

@tho-gru said in Integration of a script writen in Python:

I am wondering why this Python script works when executed via the menu

because it is then defined in the main namespace, but if
you import your script, then that script is defined in its own namespace.

A word of warning if you use the default startup.py file.
The default startup.py will be overwritten when PS is updated.
Therefore, create your own startup.py file by simply creating a new script and naming it startup.py.
If you use the version installed by PluginAdmin, it is unlikely that this version will be updated, but the PS3 version will be updated from time to time.

[Ekopalypse]

@PeterJones @Alan-Kilborn

Guess who I take all the inspiration from? :-D
From everyone who posted any scripts and Python code in general.
I think that’s how most of us learn new languages.
So from my point of view, reusing their ideas, even parts of their code is normal, I would say.
I’m not saying they don’t deserve the credits, it’s just impossible to really know everyone involved.
So, to everyone who has ever posted any code, even in other languages, thank you. :-D

Interesting. I don’t think I’ve ever known this.

So there’s a startup.py in ...\plugins\PythonScript\scripts\ folder.
If you modify it, it will work but this one is the one in danger of being overwritten on a PS update.

If you move the file to ...\plugins\Config\PythonScript\scripts\ folder then it still works just fine but is out of danger from being clobbered by a PS update.

Is that accurate information?

[PeterJones]

@Alan-Kilborn said in Integration of a script writen in Python:

Is that accurate information?

As far as I understand it.

The first, in ...\plugins\PythonScript\scripts\ folder, is the “machine scripts” instance; the second, in ...\plugins\Config\PythonScript\scripts\, is the “user scripts” version (using the nomenclature from the Python Script > Configuration… dialog).

Moreover, if you have both startup files, both will be listed in your Plugins > Python Script > Scripts menu, with the second (the “user scripts” version from the Config hierarchy) will have (User) appended to the displayed name:

I just ran an experiment with the two: I put in a print statement (well, console.write()) in both startup.py scripts; the machine-scripts instance runs first, followed by the user-scripts instance. (That’s what I thought happened, but wanted to make sure before saying it here, because the ...PythonScript/doc/usage.html#startup section is not explicit about it using both, or what order they run in.)

[Ekopalypse]

Alan, yes, it is as Peter explained.

[Alan Kilborn]

@Ekopalypse @PeterJones

Looking back on it, I probably knew most of that. :-)
But I did not know that the non-user startup.py can get clobbered.

So I’d say the best course of action for a normal user is to ignore the non-user (aka machine scripts) one, and, if you need to run stuff on startup, create your own startup.py (create it just like any other new script you’d make) and put your stuff in it.

The temptation is to just quickly throw stuff into the file that already exists – don’t do it.

[Ekopalypse]

@Alan-Kilborn - absolutely

[tho-gru]

Thanks for your additions.

I already used the startup (user) script.

Kind Regards,
Thomas

I opened the issue 205 for the difference in “preloaded” modules.

[Alan Kilborn]

@tho-gru

I think the reason for the “difference” was explained HERE, so you may want to withdraw your issue.
