Copy Link in Caret /w Ctrl+P (LuaScript)

PeterJones

That command is macro-playable, even though it’s not macro-recordable:

        <Macro name="CopyLink" Ctrl="yes" Alt="no" Shift="no" Key="80">
            <Action type="2" message="0" wParam="42082" lParam="0" sParam="" />
        </Macro>

If you paste that into your <Macros> section of shortcuts.xml and restart Notepad++, Ctrl+P will run the Copy Link entry – er, well, it will if you use Settings > Preferences > Shortcut Mapper to turn off the Ctrl+P shortcut for File > Print. – No plugin required, this will work with a vanilla copy of Notepad++.

I got the 42082 from the english.xml localization file, or equivalently from the menuCmdID.h

I don’t use LuaScript, so I don’t know the syntax: I will use the kind of phraseology that I’d use to describe how to do it in PythonScript. But I assume LuaScript has a wrapper for the NPPM_MENUCOMMAND message, which you would pass in lParam="42082" (whatever syntax the LuaScript uses: they might even have a constant/enumeration for it, similar to IDM_EDIT_COPY_LINK). I assume that LuaScript mechanism to map a shortcut to a particular script, so if you used that, you’d have the mapping.

@PeterJones Thanks, that worked ! I will use it till someone musters the generosity of posting the LuaScript Startup code :D

This is the code I got from ChatGPT, the first line was taken off another working LuaScript code I got from someone on Github (this code is broken, & doesn’t work):
– Copy Link In Caret w/o Right-Click
npp.AddShortcut(“Copy Link”, “Ctrl+P”, function()
local editor = notepad.getCurrentBuffer()
local currentPos = editor.currentPos
local startPos = editor:wordStartPosition(currentPos, true)
local endPos = editor:wordEndPosition(currentPos, true)
local link = editor:getTextRange(startPos, endPos)
if link ~= “” then
editor:copyText(link)
end
end)

Not sure I see the value at all in posting non-working code that wasn’t even written by a human. :-(

The print() lines can be removed once tested as working ok. Check the LuaScript console for the printed output to validate.

Example:

Invalid link: Topic:
Copied link: https://community.notepad-plus-plus.org/topic/24681/copy-link-in-caret-w-ctrl-p-luascript

A URL can be almost any character though usually has the substring of :// which is what string.find() searchs for to determine if is a URL and not some other word at the point of the caret.

@mpheath Wow, thanks a million ! This is exactly what I wanted. I’am so grateful to you for helping me out —this will 10x my research efforts !! Works like a charm. Amazing genius-level solution ;-) Also thank you PeterJones, your method is also flawless.

guy038

Hello, @alienfxfiend, @peterjones, @alan-kilborn, @mpheath and All,

Hum… I’m really embarrassed, @mpheath ! Because the macro, provided by @peterjones works flawlessly but your lua script does not work as expected :-(

I’ve just did a first try on my old Win XP - 32 bits machine, with N++ v7.9.2 and LuaScript v10.1 and no chance ! ( Note that the recent LuaScript versions v11 and v12 do not work with N++ v7.9.2 )

I surely miss something obvious, but I can’t see why !

Best Regards,

@guy038 Hello

Peter’s answer would be like the Copy Link already in the contextmenu source. So should be good. LuaScript can do the IDM_EDIT_COPY_LINK command though it needs to be assigned first before use. Easier than my initial code…

npp.AddShortcut("Copy this link", "Ctrl+Alt+1", function()
	local IDM_EDIT_COPY_LINK = 42082
	npp:MenuCommand(IDM_EDIT_COPY_LINK)
end)

Still on Win XP, good for you. I am on Win 7 though it is 64 bit OS.

I just downloaded the N++ portable v7.9.2 32 bit and added LuaScript which states it is v0.10 32 bit, not v10.1 that you mention. It look like v0.10.1 was released 3 days after v0.10. The v0.10 archive on Github is missing the lua.dll file though Plugin Admin did download lua.dll so perhaps it is actual v0.10.1 though the about box says v0.10 .

I have added the posted lua code in the Lua startup script, restarted N++ and tested with the LuaScript console open so as to see the printed messages. I appears to be working just like in N++ v8.5.4 .

I swapped LuaScript v0.10 with v0.10.1 which I doubt is a difference as just a appveyor.yml script was updated, so the version downloaded from Plugin Admin should still be ok. Even the checksums for the dll files are the same. Started N++ again and tested. It is working. The checksums…

    File: LuaScript\Lua.dll
  CRC-32: 30670d6b
     MD5: ca8e5c8431e0904dac146ee98eb492f5
   SHA-1: 4e522b6f0acf554974d6321581b2d8a626f1fe6d

    File: LuaScript\LuaScript.dll
  CRC-32: c0f063e1

Are these the same as your dll files? I doubt you have 64 dll files as I got a warning from N++ on startup as it could not load them, so that could not be causing the issue.

Perhaps the caret position is at the start of the URL string. Try changing this line

if col > startpos and col < endpos then

to

if col >= startpos - 1 and col < endpos then

which which gets the URL from the starting edge of it.

Finally, try restarting N++. Open the LuaScript console as it should print a result. Test with the URLs in the startup script as that is what I tested with. The shortcut in posted code is Ctrl+Alt+1 as in the number 1, not the letter L. Check the shortcut mapper in case a conflict is happening. Also try the link in the menu Plugins > LuaScript > Copy this link .

If you have further troubles, I could install Win XP into a Virtual Machine and try it there to see if I can make it fail.

Hi, @mpheath and All,

Many thanks for your reply and do not bother about installing Wn XP on a virtual machine !

Because, in addition to my old laptop, I’ve ALSO got, since July 2021, a decent Win-10 64 bits Pro machine where I installed the very last 0.12 - x64 version of LuaScript, as well as the last version of the PythonScript and NppExec plugins. Thus, here is my debug info :

Notepad++ v8.5.4   (64-bit)
Build time : Jun 17 2023 - 20:42:45
Path : E:\854_x64\notepad++.exe
Command Line : 
Admin mode : OFF
Local Conf mode : ON
Cloud Config : OFF
OS Name : Windows 10 Pro (64-bit)
OS Version : 22H2
OS Build : 19045.3086
Current ANSI codepage : 1252
Plugins : 
    mimeTools (2.9)
    NppConverter (4.5)
    NppExport (0.4)
    PythonScript (2)
    LuaScript (0.12)
    NppExec (0.8.4)

And here are the checksums for the Lua.dll and LuaScript.dll plugins :

Nom: Lua.dll
Taille: 433152 octets (423 KiB)
CRC32: 39D70D83
SHA256: 55cbc36216bfcfbf44bb551ded40f8946389f4982fb096352455ec24e987367f
SHA1: bea0917a9159d9ab67e2c40f848efb12cd3d17eb

And :

Nom: LuaScript.dll
Taille: 589824 octets (576 KiB)
CRC32: 7EC421AF
SHA256: 459f4aebe1f7843a82d092f6d899edb0fe651d89c3ee7d258dc1da26e78ea691
SHA1: 1985515dc102ef6112ae63816ab5393a33ef8ba4

So, with N++ v8.5.4, I first verified that the macro :

        <Macro name="Copy Link" Ctrl="no" Alt="no" Shift="no" Key="120">
            <Action type="2" message="0" wParam="42082" lParam="0" sParam="" />
        </Macro>

Placed in shortcuts.xml still works. Then, I noticed, as you said, that the Copy Link option is available in the Context Menu, as soon as current caret location is within the range of a link. BTW, I also, verified that this was ALREADY the case with N++ v7.9.2 on my old Win XP machine ! So, all the story could stop here !

However, I’m wondering why your previous and second version of your LuaScript, below, that I even shortened, still do not work, on my recent HP laptop !

npp.AddShortcut("Copy this link", "Ctrl+Alt+3", function()
	npp:MenuCommand(42082)
end)

I’ve just changed the shortcut to Ctrl + Alt + 2 and Ctrl + Alt + 3 in your two scripts, as I noticed, on my Win XP machine, that the Ctrl + Alt + 1 shortcut is normally used by the ComparPlus plugin, by default, to set the first tab to compare !

I also tried your work-around :

        if col > startpos and col < endpos then

to

        if col >= startpos - 1 and col < endpos then

without any success ! So, why these simple Lua scripts are bugging ???

Normally, the process should be :

Go to any tab containing a link
Use the Ctrl + Alt + 2 or Ctrl + Alt + 3 shortcut to trigger the copy of current link contents in the clipboard
Paste the clipboard contents anywhere else !

See you later,

guy038

P.S. : two additional points :

Your two scripts Copy_Link.lua and Copy_Link_2.lua are installed in the same directory than my locale install ( E:\854_x64\... )
I do not see the options Copy_Link.lua Ctrl+Alt+ 2 and Copy_Link.lua Ctrl+Alt+ 3 in the Lua menu ?

Last attempt :

I added the commands print “OK” and print “OK_2” at the end of the scripts and executed them from the Lua Console, with the commands dofile("Copy_Link.lua") and dofile("Copy_Link_2.lua")

=> Correct execution but no result, too !

mpheath

@guy038 With your last attempts of using like dofile('path\\to\\copy_link.lua') is something that I cannot get to work. No errors, no reaction at all. I tried adding the lua file into a path within package.path and tried require('copy_link') and cannot get to work.

I can only get it to work in the startup script which is saved as startup.lua in the Config directory. Access the startup script from the menu Plugins > LuaScript > Edit Startup Script .

npp.AddShortcut() does not work in a separate lua file. Probably needs to be applied only at startup when the lua subsystem of LuaScript starts.

dofile() this code as test.lua and it prints the value of package.path and nothing else, no item named TestShortcut created in the menu.

print(package.path)
npp.AddShortcut('TestShortcut', '', function() print('test') end)

npp.AddShortcut() does not want to work outside of startup.lua .

guy038

Hi, @mpheath and All,

I confirm that the command npp.AddShortcut(... works ONLY when appended to startup.lua and do not work in a separate Lua file !

And, this time, after restarting N++, the new options Copy this link Ctrl+Alt+2 and Copy this link Ctrl+Alt+3 were present in the Lua sub-menu and did the job, correctly

Finally, as this command is already included in the contextMenu.xml, I suppose that any script, whatever it is, that mimics the Copy link function, seems useless !

Again, thank you very much, @mpheath, for your support !

Best Regards,

guy038
