Adding leading zeros or additional leading space for line numbers

codenotworking

I’m curious if there is a way to add leading zeros or additional leading space for line numbers.

I have a situation where I have a file that has nearly 3000 lines. From 1 to 999, the line numbers are properly padded. But once I reach line 1000, the area expands to accommodate the larger number, shifting the main area to the right slightly, which is a bit annoying as I scroll and view the file.

I made an example gif of what is occurring.

Just wondering if there is some setting or secret file in Notepad++ I can modify. Currently I am using version 7.5.7.

I don’t think so and it seems that changing width via a scripting language isn’t successful either. Seems you need to open an issue at github but as far as I remember there has one been opened recently. Please check before reopen another one.

There’s a workaround proposed by xylographe that works for this, and it is found here: https://github.com/notepad-plus-plus/notepad-plus-plus/issues/5670

Hello, @codenotworking, @ekopalypse, @alan-kilborn, and All,

Many thanks, Alan, for pointing out this GitHub article !

So, to summarize, as the predefined STYLE_LINENUMBER is numbered 33 ( Refer below )

https://www.scintilla.org/ScintillaDoc.html#StyleDefinition

And, from the two links, below, as we can, obviously, choose any string, in order to calculate the LINENUMBER margin

https://www.scintilla.org/ScintillaDoc.html#SCI_SETMARGINWIDTHN

https://www.scintilla.org/ScintillaDoc.html#SCI_TEXTWIDTH

Let’s use the simple format “12345678”, which allows number lines between values 1 and 99,999,999 ( 8 digits )

Hence, the two commands, that I’ve personally tested :

With the Python script : editor.setMarginWidthN(0, editor.textWidth(33, "12345678"))
With the Lua script : editor.MarginWidthN[0] = editor:TextWidth(33, "12345678")

Note that if your current file contains more than 99,999,999 lines, any digit, on the left, is, then, truncated !

So, the transition between the two lines 99,999,999 and 100,000,000, bookmarked would look like, as below :

99999999 ● ( Line  99,999,999 )
00000000 ● ( Line 100,000,000 )

Hi, All,

Regarding my previous post, I’ve noticed that, after running the script commands, if you increase the zoom factor, significantly, you may miss the leftmost number digit :-((

In that case, just re-run the appropriate script command, with the same parameters !

Note that, with the native N++ numbering; this is done automatically ;-))

Cheers,

True, but this would be a rare thing (for most people). Much rarer than that little visual blip that occurs as you move through line # 1000.

But if it is really a factor for you, you could put it in a zoom-notify :

try:
    zoom_notify_installed
except NameError:
    def callback_sci_ZOOM(_): editor.setMarginWidthN(0, editor.textWidth(33, "12345678"))
    editor.callback(callback_sci_ZOOM, [SCINTILLANOTIFICATION.ZOOM])
    zoom_notify_installed = True
editor.setMarginWidthN(0, editor.textWidth(33, "12345678"))

(for Pythonscript; I don’t know the Luascript way of doing that)
