# [Isomorphic Copy](https://ms-jpq.github.io/isomorphic-copy)
**Cross platform clipboard.**
**Both remote and local**
**Works out of the 📦** with most programs that use `pbcopy`, `xclip`, `wl-copy`, etc.
Works the same locally as over SSH, inside Docker containers, et al.
It even works inside Docker over SSH and then inside Docker!, **infinitely chainable**.
---
## Networkless
`isomorphic-cp` communicates by `stdio` and `unix socket` only!
All it does is spawn subprocesses and listen to `IO`.
This makes it amazingly versatile.
---
## Daemonless
You literally just run `cssh ` or `cdocker `.
No local daemon required. The remote "daemon" is just a subprocess of a subprocess. Zero cost when you are not using it.
---
## How to use
Requires `xclip` or `wl-clipboard` under GUI linux.
**Clone** this repo to the same location on two machines. Either relative to `~` or `/`.
**Prepend** `isomorphic-copy/bin` to your `PATH` for example:
`export PATH="$XDG_CONFIG_HOME/isomorphic-copy/bin:$PATH"` in your `bash/zshrc` file.
You need to do this on both local and remote.
--
**Automatically** most applications that use `xclip`, `wl-clipboard`, `pbcopy` and so forth will use `isomorphic-copy` with zero setup.
Works just like python `virtualenv`!
--
I added two **convenience functions**:
You don't have to use these. Things like `pbcopy` and `pbpaste` will continue to work.
`echo | c` Use `c` to copy to system clipboard
`p > my_message.txt` Use `p` to paste from system clipboard
--
**Connect to remote** with one of
`cssh `
`cdocker `
Once daemon is launched, remote copy will propagate to local system clipboard.
Remote applications that use `xclip`, `pbcopy`, `wl-copy` will propagate to local system clipboard.
--
**Local -> SSH -> Docker**
If you want to copy from a `Docker` container on a remote machine.
from local run `cssh ` to remote
from remote run `cdocker ` to container
And you are set!
## Integrations
### Tmux
Copy will automatically propagate to local / remote tmux clipboard.
If daemon is run under tmux, copy will also propagate to the local tmux clipboard.
If no system clipboard is available, copy / paste will use tmux clipboard.
Copying *FROM* tmux will require this snippet.
```conf
set -g mouse on
bind -T copy-mode MouseDragEnd1Pane \
send-keys -X stop-selection
bind -T copy-mode MouseDown1Pane \
select-pane \;\
send-keys -X copy-pipe "c" \;\
send-keys -X clear-selection
```
Drag to select, click in dragged area to copy.
Replace `copy-mode` with `copy-mode-vi` if you are using vi emulation.
### Vim
Neovim will only use `xclip` if the x11 environmental variable `DISPLAY` is set.
Vim will require an autocmd event.
Add this snippet to your `vimrc`, to work for both vims.
```viml
if has('nvim')
" use unnamedplus only! or else will double set
set clipboard=unnamedplus
if getenv('DISPLAY') == v:null
exe setenv('DISPLAY', 'FAKE')
endif
else
autocmd TextYankPost * call system("c", getreg('"'))
endif
```
### Others
Most CLI applications will work out of the box. (such as lazygit, for example).
If not, check if they require `DISPLAY` like Neovim.
### Fallback
If no system / tmux clipboard is found, setting environmental variable `ISOCP_USE_FILE=1` will enable using a temp file as a crude clipboard.
It will write inside the git repo, put it somewhere safe.
