Bookmark line becomes unchecked on reopening application

Bookmark line issue.PNG

Hello, I run searches on large text files at work. Whenever I need to bookmark my searches on lines of text, I naturally check the parameter Bookmark line. The problem? If I restart the application or if I install a Notepad++ update and restart the application, all my customized preferences, such as Backward direction, the font size, Wrap around, etc. are maintained, except Bookmark line, which appears unchecked.

This is a bit annoying because I need it to be checked permanently so that I can copy the bookmarked lines on the searched text file.

Any suggestions? Maybe it’s a bug. Thank you.

It’s not a bug. It’s just not a feature I’ve heard of anyone asking for, and maybe not one that the developers have thought of to implement. If you would like Notepad++ to remember the “Bookmark line” checkbox like it remembers the other checkboxes, you can follow the FAQ instructions for making a feature request

If you’re willing to use the PythonScript plugin, I have a solution in the form of…a script!

I call the script BookmarkLineCheckboxTick.py and it looks like this:

# -*- coding: utf-8 -*-
from __future__ import print_function

#-------------------------------------------------------------------------------

from Npp import *
import inspect
import os
import ctypes
from ctypes import wintypes

#-------------------------------------------------------------------------------

user32 = ctypes.WinDLL('user32')

LRESULT = wintypes.LPARAM

SendMessageW = user32.SendMessageW
SendMessageW.restype = LRESULT
SendMessageW.argtypes = [ wintypes.HWND, wintypes.UINT, wintypes.WPARAM, wintypes.LPARAM ]

#-------------------------------------------------------------------------------

IDC_MARKLINE_CHECK = 1616
BM_SETCHECK = 0x00F1
BST_CHECKED = 1

#-------------------------------------------------------------------------------

class BLCT(object):

    def __init__(self):
        notepad.menuCommand(MENUCOMMAND.SEARCH_MARK)
        find_dlg_hwnd = user32.FindWindowExW(None, None, u'#32770', u'Mark')
        bookmark_checkbox_hwnd = user32.GetDlgItem(find_dlg_hwnd, IDC_MARKLINE_CHECK)
        SendMessageW(bookmark_checkbox_hwnd, BM_SETCHECK, BST_CHECKED, 0)

#-------------------------------------------------------------------------------

if __name__ == '__main__': BLCT()

It can be set to run at Notepad++ startup by setting the scripting plugin’s Initialisation parameter to ATSTARTUP and then putting the following lines into the startup (User) script:

import BookmarkLineCheckboxTick
BookmarkLineCheckboxTick.BLCT()

The result of this will be that the Bookmark line checkbox will always be ticked when Notepad++ starts.

I’m willing - but I don’t want that use case. I want to check the “Highlight all” in the Search => Incremental Search “window”.

I modified your script, but having some issues. The Incremental Search windows is “attached” to Notepad++ so I don’t see a new Windows class name (#32770 like for the “Mark” pop-up). Also, for the Window title - “Mark” works nicely for the Mark window popup - what do I use for the Incremental Search “window” which is “attached” to Notepad++ - the Notepad++ “title” I have changes based on the open filename. I think i got the other stuff done:

replace IDC_MARKLINE_CHECK with IDC_INCFINDHILITEALL (1690, from ScintillaComponent/FindReplaceDlg_rc.h)
MENUCOMMAND.SEARCH_MARK replaced with MENUCOMMAND.SEARCH_FINDINCREMENT

So my script does open the Incremental Search “window”, but it does not check the “Highlight all” checkbox. Any pointers?

Cheers.

It’s all about having that control’s handle (hwnd).

Cobbling some code together by stealing a lot from THIS THREAD, I came up with this:

# -*- coding: utf-8 -*-
from __future__ import print_function

import ctypes
from ctypes.wintypes import BOOL, HWND, LPARAM

WNDENUMPROC = ctypes.WINFUNCTYPE(BOOL, HWND, LPARAM)

FindWindow = ctypes.windll.user32.FindWindowW
SendMessage = ctypes.windll.user32.SendMessageW
EnumChildWindows = ctypes.windll.user32.EnumChildWindows
GetClassName = ctypes.windll.user32.GetClassNameW
GetWindowText = ctypes.windll.user32.GetWindowTextW
GetWindowTextLength = ctypes.windll.user32.GetWindowTextLengthW
create_unicode_buffer = ctypes.create_unicode_buffer

curr_class = create_unicode_buffer(256)

BM_SETCHECK = 0x00F1
BST_CHECKED = 1

incr_search_highlight_all_hwnd = [ 0 ]

def EnumCallback(hwnd, _):
    GetClassName(hwnd, curr_class, 256)
    length = GetWindowTextLength(hwnd)
    if length:
        buff = create_unicode_buffer(length + 1)
        GetWindowText(hwnd, buff, length + 1)
        print('class:', curr_class.value, '|', 'text:', buff.value)
        if buff.value == u'&Highlight all':
            incr_search_highlight_all_hwnd[0] = hwnd
    else:
        print('class:', curr_class.value)
    return True  # let enumeration continue

notepad.menuCommand(MENUCOMMAND.SEARCH_FINDINCREMENT)
notepad_hwnd = ctypes.windll.user32.FindWindowW(u'Notepad++', None)
if notepad_hwnd:
    EnumChildWindows(notepad_hwnd, WNDENUMPROC(EnumCallback), 0)
    if incr_search_highlight_all_hwnd[0]:
        SendMessage(incr_search_highlight_all_hwnd[0], BM_SETCHECK, BST_CHECKED, 0)

It’s instructive to look at the PythonScript console as it runs – although for me it seems to write to the console very slowly and I don’t know why this is…

if buff.value == u’&Highlight all’:

Also not sure why this text seems to have a Alt+h keyboard accelerator as I don’t see how you can use it in Notepad++'s UI.

One more thing I’m not sure of: Why I had said that.
If a control in the Incremental Search window has input focus, e.g. the Find edit box, then Alt+h will focus and toggle the Highlight all checkbox setting.
