Copying highlighted text lines from 1 Notepad++ file to another

PeterJones

I can confirm that using either the NppExport bundled with Notepad++ (plugin v0.2.9.21) or the slightly newer plugin v0.3.0, it does not behave as expected.

If I take the perl snippet:

my $mvar = 1;
local $lvar = 1;
state $svar = 1;
our $ovar = 1;

which properly highlights as Perl, then apply Using 3rd Style; when I then use NppExport > Copy HTML to clipboard or … Copy RTF…, and paste into MS Word (or presumably another HTML-or-RTF-clipboard-aware editor), then I see that it properly copy/pasted the HTML or RichText for the syntax highlighting, but not for the Using 3rd Style.

It appears that @chcg has not been on since last Fall, so invoking his name won’t bring him in to answer here.

Thus, I made feature-request/bug-report NppExporter issue#15, pointing to this discussion.

Ok, so I am expecting it to behave in a way that doesn’t actually work.

What are my other options for making this Copy & Paste of regular text with Color Highlighting intact from one NPP file to another?

I don’t think you currently have any “great” options open to you.
Since your source is an N++ document, and your destination is same, I suppose some scripting could be written that would “notice” the coloring in the souce of the copy, and recreate it in the paste destination at paste time.
Somewhat of a “copy special” followed by a “paste special”.
If that’s of interest to you, I could see what I could script up; no promises on a super-timely delivery though, as this is all “pro bono” work. :-)
You’d have to be willing to use the Pythonscript plugin.

George Rogers

I’m open to that if you can figure something out and no promises expected

Much Appreciated

Okay, so here we go. We’ve got TWO scripts:

Somewhat obviously, you need to do a “copy special” before you do a “paste special”. If you do a normal Copy and follow that with a “paste special”, you will get the result from the most-recent “copy special”, not from the normal Copy. Again, all fairly obvious.

Perhaps assign a keycombo to each – suggest Shift+Ctrl+c and Shift+Ctrl+v – but try the scripts out via the menus first, to make sure they run and have the desired effect.

As a bonus, one could use this pair of scripts to manipulate a “second” text clipboard, completely independent of the real clipboard, and never even use the style/color copying ability. Just cuz sometimes you NEED 2 clipboards!

If you need help with the Pythonscript side of things (installing it, creating scripts, assigning keycombos to run scripts, etc.) just say so.

And of course I botched the names of the scripts, being inconsistent about them both (the names of the scripts in the two-bullet list are different from the names immediately before each script). Oh, well…

Hello, @george-rogers, @alan-kilborn, @peterjones and All,

Alan, just tried this two scripts and, indeed, it fully copy/pastes the 5 style tokens, as well as the mark style and the Incremental search style ;-)) Well done ! We even have a 2nd clipboard as a bonus !

However, I don’t see the immediate benefit for @george-rogers as, obviously, all these highlightings are lost for, both, the original and the copied file, once, you start Notepad++, again !

Alan, I can see that your “status” as a Python script writer, monopolizes most of your time. But, maybe, you can find a few minutes to devote to the proposals I’ve made to you about this other Python script :

True. I’m working on a “solution” to this as well, see HERE.

Yes, I’m working on this one as well.
My in-progress version got a big, well, shall we say, “bigger” (more features) than first intended!
I really need to exercise “scope control”. :-)
Keep an eye on the thread of that posting in the coming days (weeks?).

But note that I’ll probably work to finish the “style save” script FIRST (sorry).
I try (somewhat unsuccessfully) to pipeline things in FIFO order, without getting “too many” things going at once.

Alan, I can see that your “status” as a Python script writer, monopolizes most of your time

Never saw that as a “status” LOL.
And my general rule is that I don’t take on script-writing for things that I wouldn’t personally use, or possibly for things I wouldn’t use but have some other interesting (to me) aspect.

@guy038 said in Copying highlighted text lines from 1 Notepad++ file to another:

Actually, the “incremental search style” isn’t handled by the provided scripts.
The reason is that it is too “dynamic”.
The other styles have more “permanence” to them.

One could certainly add it to the list in the “copy-special” script code, though (no need for it to be in the “paste-special” code). Here are the details about it from the N++ source:

#define SCE_UNIVERSAL_FOUND_STYLE_INC 28

George Rogers

Your time and efforts are Much Appreciated! I am admittedly a Notepad++ newbie when it comes to scripts and customization. Maybe you can point me to a YouTube video or video screenshare which shows me how to integrate these scripts. Thanks Again!

Alan Kilborn

@George-Rogers

Someday we’ll turn the generic procedure into a FAQ.

Steps:

Use Plugins admin to install the PythonScript plugin
Menu to Plugins > Python Script > New Script
Provide a (file) name for the script; you don’t need to specify an extension – .py will be added automatically
Press the Save button to close out the Save As dialog box.
At this point your script file will be showing and is empty; copying and pasting one of the scripts from above seems like a fine idea :-)
Save the file
To execute your script, menu to Plugins > Python Script >Scripts > (pick the name of your script)

If you can successfully get that far with it, we can explain to you how to bind a keycombo to it to execute the script that way (which is better than menuing for an often-used script).

guy038

Hi, @alan-kilborn and All,

when I did the test, I used the maximum number of styles and I didn’t notice that the incremental search style was not copied !

Cheers,

guy038

Alan Kilborn

@guy038

Actually (thinking more about it), if you want the Incremental Search or even the Smart Highlighting color to be part of the copy/paste, upon pasting it will lose its temporal nature and becomes permanent! So that’s a way to get a few more colors with this technique!

Here’s the info for Smart Highlighting :

#define SCE_UNIVERSAL_FOUND_STYLE_SMART 29

And so, here’s a modification to a section of the “copy special” script to include these:

# the following names are from the N++ source code:
SCE_UNIVERSAL_FOUND_STYLE_EXT1  = 25  # Style #1
SCE_UNIVERSAL_FOUND_STYLE_EXT2  = 24  # Style #2
SCE_UNIVERSAL_FOUND_STYLE_EXT3  = 23  # Style #3
SCE_UNIVERSAL_FOUND_STYLE_EXT4  = 22  # Style #4
SCE_UNIVERSAL_FOUND_STYLE_EXT5  = 21  # Style #5
SCE_UNIVERSAL_FOUND_STYLE       = 31  # redmarking style
SCE_UNIVERSAL_FOUND_STYLE_INC   = 28  # incremental-search style
SCE_UNIVERSAL_FOUND_STYLE_SMART = 29  # smart-highlighting style

indicator_list = [
    SCE_UNIVERSAL_FOUND_STYLE_EXT1,
    SCE_UNIVERSAL_FOUND_STYLE_EXT2,
    SCE_UNIVERSAL_FOUND_STYLE_EXT3,
    SCE_UNIVERSAL_FOUND_STYLE_EXT4,
    SCE_UNIVERSAL_FOUND_STYLE_EXT5,
    SCE_UNIVERSAL_FOUND_STYLE,
    SCE_UNIVERSAL_FOUND_STYLE_INC,
    SCE_UNIVERSAL_FOUND_STYLE_SMART,
    ]

So I think around the time of v.7.6.1, Plugins Admin was going through some growing pains.
That may be causing the trouble.
Any issues with updating to v.7.8.6, say?
You can certainly stick with the 32-bit version if you want.

George Rogers

I can give that a shot
How would I unwind that update and revert back to V7.6.1 in case I needed to?

Personally I would download a zipped version as it can run
