Copying the current line number to the clipboard

[Alan Kilborn]

Notepad++ 8.7.6 introduces a way to copy the currently active line number to the clipboard, see some discussion HERE, but it might be considered a bit “klunky” for those that need to do this often.

As a faster alternative, I’ll offer up this method:

Create a .bat file in a reasonable place in your file system. I named mine copy_current_line_number.bat and for purposes of the rest of this technique I’ll use C:\batch\copy_current_line_number.bat as its location.

The batch file contents should be:

:: see https://community.notepad-plus-plus.org/topic/26585
:: Notepad++ Run menu > Run... > The Program to Run: entry:
:: cmd /c C:\batch\copy_current_line_number.bat $(CURRENT_LINE)
@echo off
set CURR_LINE_MINUS_1=%1
set /a CURR_LINE = %CURR_LINE_MINUS_1% + 1
:: echo the variable without putting a line-ending on it:
echo|set /p=%CURR_LINE%|clip

As the comments in the script indicate, go to the Notepad++ Run menu and choose Run… and then put the following in The Program to Run: box: cmd /c C:\batch\copy_current_line_number.bat $(CURRENT_LINE) (changing your pathname to the batch file as appropriate for you).
Then press Run.

Save the entry (go back in like you want to run it again but choose the Save button this time) so that it appears on the Run menu in the future; I called mine Copy current line number, but… as you like.
Optionally (but recommended) assign a shortcut keycombo to it, for fast access.

LATER EDIT: I added a comment into the script:
:: echo the variable without putting a line-ending on it:

Hello @alan-kilborn and All,

Here is a variant of your batch script which should work, too :

:: see https://community.notepad-plus-plus.org/topic/26585
:: Notepad++ Run menu > Run... > The Program to Run: entry:
:: cmd /c C:\batch\copy_current_line_number.bat $(CURRENT_LINE)

@echo OFF
set LINE=%1
set /a LINE += 1
echo %LINE% | clip

Best Regards,

Comments on the variant:

• the original emphasizes that what N++ sends is one less than the current line value; the variant deemphasizes that nuance by reusing the same variable name for a different purpose
• the variant copies the current line value PLUS a CRLF to the clipboard; the original copies only the text of the line number (no trailing CRLF) – probably the original could have had a comment about this and the seemingly odd set /p command (but it is a common batch idiom to me, so I didn’t add a comment originally – I did with a “LATER EDIT”)

I do it often via

#
# This is used to fetch the current line number into the copy/paste buffer
#
# See https://community.notepad-plus-plus.org/topic/20224
#
editor.copyText(str(editor.lineFromPosition(editor.getCurrentPos())+1))

As Ctrl+G is Notepad++'s goto-line thing I added a shortcut for Ctrl+Shift+G that is mapped to that script.

The source for this script plus notes on how to add it to Notepad++ are in the Is there a way to get the current line number into the copy/paste buffer? forum thread.

Of course it is easily scriptable, but it doesn’t have to be, as I show with the batch file approach.

I believe readers that aren’t already into scripting are reluctant to get involved for one reason or another.

The batch file also has some baggage as it requires a separate file to be kept somewhere in the file system, but it doesn’t require a plugin.

Another alternative is to use only the commandline:

cmd /v:on /s /c "set /a line=$(CURRENT_LINE)+1 & <nul set /p "=!line!"|clip"

Add as a Run entry. No batch file dependency.

Well…nice.
A bit too much Batch file “wizardry” there for me, but OK.
I like wizardry (of course) but only to a point. :-)

I’m OK with having an extra file kicking around, as I have a directory with several N++ related batch files already.

It’s much like regexp wizardry.

Something I learned from @mpheath’s batch file wizardry is that I had not known that when in ENABLEDELAYEDEXPANSION mode that you are allowed to set or change variable and that the new value for that variable is available later in the same line.

As a standalone SET /A outputs the result of the expression we can shorten it up to

cmd /c "set /a line=$(CURRENT_LINE)+1 | clip"

Which also gets the topic of this thread back onto Notepad++. :-)
