last modified date in status bar?

Claudia Frank

with python script like discussed here
and code to get the last modified timestamp like

import os
from datetime import datetime

modified_time = os.path.getmtime(notepad.getCurrentFilename())
last_modified_date = datetime.fromtimestamp(modified_time)

Cheers
Claudia

patrickdrd

ok but how does this refresh when I save the file (new date should be shown)?

Claudia Frank

@patrickdrd

yes, I assume the uiupdate callback is sufficient as it is triggered quite often but in case
it is needed, the notepad object provides also a filesaved callback.
So something like

from Npp import editor, notepad, SCINTILLANOTIFICATION, NOTIFICATION, STATUSBARSECTION
import os
from datetime import datetime

def StatusbarSelOverride(args):
    modified_time = os.path.getmtime(notepad.getCurrentFilename())
    last_modified_date = datetime.fromtimestamp(modified_time)
    notepad.setStatusBar(STATUSBARSECTION.DOCSIZE, '{}'.format(last_modified_date))

editor.callback(StatusbarSelOverride, [SCINTILLANOTIFICATION.UPDATEUI])
notepad.callback(StatusbarSelOverride, [NOTIFICATION.FILESAVED])

should do the trick, of course you need to adapt it to your needs - is just a quick tip
on how to achieve your goal.

patrickdrd

yes, it’s pretty good!!

some help with date formating?

I would prefer dd/mm/yyyy hh:mm please :D

e.g. 13/02/2018 15:14

@patrickdrd

using

last_modified_date.strftime('%d/%m/%Y %H:%M')

should do the trick.
More infos, if other format is wanted can be seen here.

This might be a more direct link than Claudia’s…for what seems to be wanted for adjustment.

patrickdrd

why do I have to link anywhere inside the file in order for it to work?
I mean when I double click on a file from windows explorer,
I have set initialization atstartup,
does it need something else/more maybe?

patrickdrd

I think I found that, I added:

notepad.callback(StatusbarSelOverride, [NOTIFICATION.READY])

notepad.callback(StatusbarSelOverride, [NOTIFICATION.READY])

Interesting. I found that I don’t need the “READY”–I don’t have to click inside the document tab to see the mod time updated after loading a file. I don’t use Explorer integration such that a double-click opens the file in Notepad++, but it works for me either via Explorer right-click or drag-n-drop from Explorer.

patrickdd, have you been able to add the modified date to the section 1 of the statusbar, where the language name is, without overriding the language name? if so, can you please post the full code? thanks.

@SalviaSage said:

section 1 of the statusbar

Just change .DOCSIZE to .DOCTYPE. No need to post more code.

That kind of change should be really obvious from the third posting I made (the one with the images of the status bar) in this thread.

patrickdrd

Scott, the difference is that notepad++ is closed in my case, before opening the file, in that case only initial script doesn’t work

Scott Sumner

Yeah, that’s a case I don’t think about, or code for. Because, as the best program on my PC, Notepad++ never gets closed. :-D

Claudia Frank

@patrickdrd

does READY callback work for you?
It seems that this one can’t really be used when running on linux.
BUFFERACTIVATED might be another callback which is useful in such cases.

…without overriding the language name?

Ah…so I guess I missed this part of @SalviaSage 's posting. Okay, so there is no prebuilt function to get the statusbar data, like there is to set the statusbar data…but we can create one:

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

def npp_get_statusbar(statusbar_item_number):

    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
    create_unicode_buffer = ctypes.create_unicode_buffer
    WM_USER = 0x400; SB_GETTEXTLENGTHW = WM_USER + 12; SB_GETTEXTW = WM_USER + 13

    npp_get_statusbar.STATUSBAR_HANDLE = None

    def get_data_from_statusbar(statusbar_item_number):
        retcode = SendMessage(npp_get_statusbar.STATUSBAR_HANDLE, SB_GETTEXTLENGTHW, statusbar_item_number, 0)
        length = retcode & 0xFFFF
        type = (retcode >> 16) & 0xFFFF
        text_buffer = create_unicode_buffer(length)
        retcode = SendMessage(npp_get_statusbar.STATUSBAR_HANDLE, SB_GETTEXTW, statusbar_item_number, text_buffer)
        retval = '{}'.format(text_buffer[:length])
        return retval

    def EnumCallback(hwnd, lparam):
        curr_class = create_unicode_buffer(256)
        GetClassName(hwnd, curr_class, 256)
        if curr_class.value.lower() == "msctls_statusbar32":
            npp_get_statusbar.STATUSBAR_HANDLE = hwnd
            return False
        return True

    EnumChildWindows(FindWindow(u"Notepad++", None), WNDENUMPROC(EnumCallback), 0)

    return get_data_from_statusbar(statusbar_item_number) if npp_get_statusbar.STATUSBAR_HANDLE else None

Thus to add the modification timestamp info to the first section of the status bar, one would call npp_get_statusbar(0) and then use the returned string (if not None) by adding the time to it, e.g.:

notepad.setStatusBar(STATUSBARSECTION.DOCTYPE, npp_get_statusbar(0) + ' ' * 8 + last_modified_date)

I’m sure the basis for this status bar code goes back to some @Claudia-Frank code, but I can’t find the reference to it right now. Sorry, CF.

-----
note from the future: if this code gives you all NULL for the characters read back from the status bar, use the updated code found in this 2024 post

patrickdrd

yes, it works CF

I tried BUFFERACTIVATED but it didn’t work

SalviaSage

@patrickdrd, have you been able to get this working? I’ve been trying here from my end. I can’t get the last modified date to display on the statusbar. If you have been able to get this working, can you please post the code?

Thank you.

patrickdrd

from Npp import editor, notepad, SCINTILLANOTIFICATION, NOTIFICATION, STATUSBARSECTION
import os
from datetime import datetime

def StatusbarSelOverride(args):
modified_time = os.path.getmtime(notepad.getCurrentFilename())
last_modified_date = datetime.fromtimestamp(modified_time)
notepad.setStatusBar(STATUSBARSECTION.DOCTYPE, ‘Mod: {:%d/%m/%Y %H:%M}’.format(last_modified_date))

editor.callback(StatusbarSelOverride, [SCINTILLANOTIFICATION.UPDATEUI])
notepad.callback(StatusbarSelOverride, [NOTIFICATION.FILESAVED])
notepad.callback(StatusbarSelOverride, [NOTIFICATION.READY])

SalviaSage

I still can’t figure out how to add the timestamp and still keep the original contents of a statusbar section.

Scott Sumner, I would appreciate it very much if you can fix this code and post it here. thank you.

patrickdrd

I don’t think you need the original contents, if we’re talking about the first tab,
is DOCTYPE really that important for you?
If so, why?
I can’t think that’s important, that’s why I’m overwriting it
