Smart HighLighting for multiple view !

Hello,

I search a way to display all variables on all view.

Thank you for your help

Hello Marvin Gerardin

I have a python script which could almost do what you want.
What needs to be done first is described here.

def clearScintillaCallbacks():
    editor.clearCallbacks([SCINTILLANOTIFICATION.DOUBLECLICK, SCINTILLANOTIFICATION.INDICATORCLICK]) 

clearScintillaCallbacks()
    
def clearIndicators():
    text_end_position1 = editor1.getLength()
    text_end_position2 = editor2.getLength()

    editor1.setIndicatorCurrent(8)
    editor1.indicatorClearRange(0, text_end_position1)

    editor2.setIndicatorCurrent(8)
    editor2.indicatorClearRange(0, text_end_position2)

def toggleview():
    # 0 = main_view
    # 1 = second_view
    current_doc_index_main_view = notepad.getCurrentDocIndex(0)
    current_doc_index_second_view = notepad.getCurrentDocIndex(1)

    if notepad.getCurrentView() == 0:
        notepad.activateIndex(1, current_doc_index_second_view)
    else:
        notepad.activateIndex(0, current_doc_index_main_view)

def colorize():

    selected_text = editor.getSelText()
    
    clearIndicators()

    toggleview()
    
    matches = []
    editor.research('\\b{0}\\b'.format(selected_text), lambda m: matches.append(m.span(0)))

    for match in matches:
        editor.indicSetStyle(8,INDICATORSTYLE.ROUNDBOX)
        editor.indicSetFore(8,(117,217,117))
        editor.indicSetAlpha(8,255)
        editor.indicSetOutlineAlpha(8,255)
        editor.indicSetUnder(8,True)   
        editor.setIndicatorCurrent(8)
        editor.indicatorFillRange(match[0], match[1] - match[0])  
    
    toggleview()
    
def sci_callback_DOUBLECLICK(args):
    if editor2:
        colorize()
    else:
        clearScintillaCallbacks()

def sci_callback_INDICATORCLICK(args):
    clearIndicators()
    
editor.callback(sci_callback_DOUBLECLICK, [SCINTILLANOTIFICATION.DOUBLECLICK]) 
editor.callback(sci_callback_INDICATORCLICK, [SCINTILLANOTIFICATION.INDICATORCLICK])

I hope that code itself is self-explaining mostly therefore I only describe
the critical parts and how it should be used.

The script itself registers two callback functions,
sci_callback_DOUBLECLICK and sci_callback_INDICATORCLICK.

When you doubleclick on a text the function gets called
and tries to find the selected word in the 2nd view. If it
can be found it marks it. If you click (only one mouse click)
on the marked text, highlighting disappears.
If you click anywhere else only the highlighted text in this view
loses its markings. If you close the second view and double click
on a text then all callbacks will be cleared.

So, after you created the script
run it
open both views and
play with it by double clicking words.

As already described, 2nd view needs to be active before
you double click words or callbacks get cleared and you
need to run the script again.

One minor issue I discovered while testing.
It happened to me that words which were already
highlighted got cleaned again. Not sure why?
But it looks like this only happens if you
often double click in short time.

If this is all greek to you let me know I try to clarify.

Cheers
Claudia

Hello Marvin-Gerardin

at the beginning of your script put

import re

which means import the regular expression module.

and change the line

editor.research('\\b{0}\\b'.format(selected_text), lambda m: matches.append(m.span(0)))

with

editor.research('{0}'.format(selected_text), lambda m: matches.append(m.span(0)),re.IGNORECASE)

which forces the research function to, well, ignore the case. And missing of \\b has the additional feature to ignore
whether this is a whole word or just part of a word.

Cheers
Claudia

Hello,

I don’t see the

import re

line, which would break the whole script.
Could you open console (Plugins->Pytrhon Script->Show Console)
and run the script again. Do you get any errors?

Cheers
Claudia

Marvin Gerardin · Dec 31, 2015, 4:59 PM

is my script:
https://drive.google.com/file/d/0B884biTIbPZ-ekU3V2VqZGtKXzg/view?usp=sharing

in :
C:\Users*\AppData\Roaming\Notepad++\plugins\Config\PythonScript\scripts

I do not understand what I have to do in the console :/

I have a message:
PluginsManager::runPluginCommand Exception
Unknown exeception

and this : http://i64.tinypic.com/4r2hqe.png

@Marvin-Gerardin
sorry have to leave - will come back on this next year ;-)

So let’s summarize.
The script worked before but not as expected
because the original version matched only whole words
and not if the searched word is part of another word.

To change this I changed

editor.research('\\b{0}\\b'.format(selected_text), lambda m: matches.append(m.span(0)))

to

editor.research('{0}'.format(selected_text), lambda m: matches.append(m.span(0)))

then I thought maybe there can be also a difference in notation
therefore I included regex module

import re

and added the ignorecase flag to the research function.

editor.research('{0}'.format(selected_text), lambda m: matches.append(m.span(0)),re.IGNORECASE)

Which broke not only your uploaded code, which by the way is working for me,
but also the python script plugin??

This is weird. There is nothing fancy here. re module is part of the standard python lib.

OK, please comment the import re line

# import re

and change the editor.research … to

editor.research('{0}'.format(selected_text), lambda m: matches.append(m.span(0)))

and do another test.

You do not need to do anything in the python script console, just open it, it serves as an
error output window if something within the python code is wrong.
For example if you add the re.IGNORECASE flag but you do not import re module first
the error would be shown in the console window as soon as you double click on a word.

Traceback (most recent call last):
  File "...\Notepad++\plugins\Config\PythonScript\scripts\Highlight.py", line 42, in sci_callback_DOUBLECLICK
    colorize()
  File "...\Notepad++\plugins\Config\PythonScript\scripts\Highlight.py", line 29, in colorize
    editor.research('{0}'.format(selected_text), lambda m: matches.append(m.span(0)),re.IGNORECASE)
NameError: global name 're' is not defined

May I ask you which OS, npp and python script plugin version you use?

Cheers
Claudia
