copypasta-ext

A clipboard library providing useful extensions for the copypasta library.

I had a growing annoyance with copypasta, because the clipboard is cleared on the Linux/X11 platform when your application exits as per X11 design. The crate maintainer didn't want to implement workarounds (for valid reasons). This copypasta-ext crate provides additional clipboard contexts that solve this, along with a few other additions.

Here are some of these additions:

• X11ForkClipboardProvider: forks process and sets clipboard, keeps contents after exit
• X11BinClipboardProvider: invokes xclip/xsel to set clipboard, keeps contents after exit
• Osc52ClipboardContext: use OSC 52 escape sequence to set clipboard contents
• CombinedClipboardProvider: combine two providers, use different for getting/setting clipboard

To guess at runtime what clipboard provider is best used see the DisplayServer class. Enable all desired compiler feature flags for clipboard systems to support, and use DisplayServer::select().try_context() to obtain a clipboard context.

This crate should work with the latest copypasta. Feel free to open an issue or pull request otherwise. The copypasta crate is exposed as copypasta_ext::copypasta.

Example

Get and set clipboard contents. Keeps contents in X11 clipboard after exit by forking the process. Falls back to standard clipboard provider on non X11 platforms. See x11_fork module for details.

use copypasta_ext::prelude::*;
use copypasta_ext::x11_fork::ClipboardContext;

fn main() {
    let mut ctx = ClipboardContext::new().unwrap();
    println!("{:?}", ctx.get_contents());
    ctx.set_contents("some string".into()).unwrap();
}

Get and set clipboard contents. Keeps contents in X11 clipboard after exit by invoking xclip/xsel. Falls back to standard clipboard provider on non X11 platforms. See x11_bin module for details.

use copypasta_ext::prelude::*;
use copypasta_ext::x11_bin::ClipboardContext;

fn main() {
    let mut ctx = ClipboardContext::new().unwrap();
    println!("{:?}", ctx.get_contents());
    ctx.set_contents("some string".into()).unwrap();
}
