feat: variation of #3334 by Uanela · Pull Request #3336 · nvim-tree/nvim-tree.lua

Uanela · 2026-06-14T23:05:36Z

Hello @alex-courtis this is simply a variation of what we've been discussing at #3334 I just wanted to show it in practice and is btw the thing that I've been dogfooding, I am thinking in even adding option to download a file directly when an url is on the register (maybe for my own locally if this is too nichy).

Changes

1 - gy - remains as it is, and now supports visual operation which copies a list of comma separated absolute paths
2 - gp - this is used to paste while copying
3 - gx - this is used to paste while cutting.

Added gp to automatically download when find a ^http, currently is just local on my machine.

This is looking great, only minor changes required.

Please:

handle spaces etc. in register as per gp test case, moving to a newline delimited format as per "standard" with newlines between files, but not after the last file
move Node:get_basename to Clipboard

Test cases:

gy

copy one /home/alex/src/linux/.mailmap
visual copy /home/alex/src/linux/.pylintrc,/home/alex/src/linux/.rustfmt.toml
copy root /home/alex/src/linux/
~~visual copy root and other nodes~~
root is not copied, however that's OK. This is existing behaviour and arguably a feature, as copying root and other files makes no sense.

ge

copy one .mailmap
visual copy .pylintrc,.rustfmt
copy root linux
~~visual copy root and other nodes, ok, see above~~

gp

paste one /home/alex/src/linux/MAINTAINERS
paste many /home/alex/src/linux/COPYING,/home/alex/src/linux/CREDITS
FAIL - paste with spaces /home/alex/src/linux/CREDITS, /home/alex/src/linux/Kbuild, /home/alex/src/linux/Kconfig
[NvimTree] Could not copy /home/alex/src/linux/CREDITS - ENOENT
paste one inexistent /home/alex/src/linux/xxx
[NvimTree] Could not copy /home/alex/src/linux/xxx - ENOENT
paste many, one inexistent /home/alex/src/linux/Kbuild,/home/alex/src/linux/xxx,/home/alex/src/linux/MAINTAINERS
[NvimTree] Could not copy /home/alex/src/linux/xxx - ENOENT
others copied correctly
paste mixed nodes and directories /home/alex/src/linux/zzz/,/home/alex/src/linux/aaa

gx

Test cases as per gp
Multiple source removed when in same instance /home/alex/src/linux/Kconfig,/home/alex/src/linux/MAINTAINERS
Multiple source removed in other instance in the same directory /home/alex/src/linux/.clang-format,/home/alex/src/linux/.clippy.toml

 end

+function Node:get_basename()
+  if self.name == ".." then


On further reflection, changing the ".." makes me nervous. Yes it's legacy, however it is present in many places in Clipboard hence we shouldn't change it when building this feature.

Let's keep it localised - please move this method to Clipboard so that it doesn't spread to other functionality.

That would be great, I have some use cases for it. Out of scope, future PR please :)

alex-courtis · 2026-06-17T01:00:01Z

Wild and crazy idea after reading comments on previous PR:

Remove `gp`: `p` can handle all the cases

If there are files copied or cut in the current instance, paste them as per original Clipboard:paste()
Else if the system/register clipboard contains files, paste them as per use_register = true

`Clipboard:copy()` and `:cut()` copy to system clipboard

These methods should also work as per gy, copying absolute paths to the system/register clipboard

This is something I've tried to do many times - c a file in one instance and p into another, which of course fails.

`gx`

This is a niche case, however would need to be retained: we don't have any information in the clipboard to identify cut vs paste hence it must be explicit.

I finally installed the gnome file manager nautilus and inspected the clipboard mime types when copying multiple files:

: ; wl-paste --list-types
x-special/gnome-copied-files
text/plain;charset=utf-8
text/uri-list
application/vnd.portal.filetransfer
application/vnd.portal.files


: ; wl-paste --type text/plain\;charset=utf-8
/home/alex/src/linux/.gitattributes
/home/alex/src/linux/.gitignore
/home/alex/src/linux/.mailmap


: ; wl-paste --type text/uri-list
file:///home/alex/src/linux/.gitattributes
file:///home/alex/src/linux/.gitignore
file:///home/alex/src/linux/.mailmap


: ; wl-paste --type application/vnd.portal.filetransfer
10924863569610452011%


: ; wl-paste --type application/vnd.portal.files
11848482484090875390%


: ; wl-paste --type x-special/gnome-copied-files
copy
file:///home/alex/src/linux/.gitattributes
file:///home/alex/src/linux/.gitignore
file:///home/alex/src/linux/.mailmap%

: ;

Today I think we should at least match the text/plain standard - use newline delimited files instead of comma delimited. Note that there is no newline at the end of the last file. Spaces are not escaped.

text/uri-list is interesting and something that we could do in the future, however I'm not sure how easy or possible it is to set the mime type is within Nvim.

x-special/gnome-copied-files is completely gnome specific, however it inspires the possibly of something like x-special/nvim-tree-copied-files, which we could use to specify the copy/cut operation. Maybe not so useful.

For reference, this is what a gy results in:

: ; wl-paste --list-types
text/plain
text/plain;charset=utf-8
TEXT
STRING
UTF8_STRING

: ; wl-paste --type UTF8_STRING
/home/alex/src/linux/Kbuild,/home/alex/src/linux/Kconfig

: ; wl-paste --type TEXT
/home/alex/src/linux/Kbuild,/home/alex/src/linux/Kconfig

: ; wl-paste --type STRING
/home/alex/src/linux/Kbuild,/home/alex/src/linux/Kconfig

: ; wl-paste --type text/plain
/home/alex/src/linux/Kbuild,/home/alex/src/linux/Kconfig

: ; wl-paste --type text/plain\;charset=utf-8
/home/alex/src/linux/Kbuild,/home/alex/src/linux/Kconfig

: ;

KDE dolpin operates similarly except that it does not copy text/plain

Makes total sense removing gp and making c and x take text to register.

The only thing is that x would still mean nothing, only when gx it would cut. Or maybe let gp to mean paste while cutting bc to some extent gx sounds like cut paths bc of gy, or even xp or something else.

That's great.

The unique problem usinf this approach is that it will resamble protocol and hence we won't be able to paste from anywhere else by simply grabbing the absolute path and vice-versa maybe.

This would suite better if we kept bgy to use protocol and keep gy as it is (only add the newline support), because if I visually gy I expect a list of absolute paths not nvim-tree specific thing.

Yeah that's a tricky one, there's no "natural" option. I'm easy for any mapping, however we can't do xp as x is taken.

Yes, let's just go with newlines for now. This branch is working.

We can add a protocol in the future :)
Remember that we can "break" this in the future as we're defining communication between nvim-tree instances which is not API.

The protocol will break OS level operation, which I think is one of the biggest win for this.

And yes protocol would make this nvim specific but I think it would be cooler to make it work anywhere.

Changes To Be Made

Add register operation on c and x
Add multline support
Remove gx in favor of gp to mean paste while cutting. This avoids ambiguity as p will operate locally and between instances
Make p decide whether use the clipboard or the register

Together with those mentioned earlier.
