Question about Wasm & clipboard

[f-saez]

Hi,

I've run into troubles with clipboard ans WASM.
For what I've seen, it works perfectly well with the demo hosted in github (FontBook), but I'm unable to make it works.
If I build and run egui_demo on my machine, it works. As soon as I try to use egui_demo from another machine on my local network, the clipboard stop working. Basically, I've just copied the content of docs directory, nothing more.
I've tried with apache or simple_http_server, it doesn't matter.
I must have forgotten or misunderstood something obvious.

If someone could give me a hint ...

I think this is because the newer Web "Clipboard API" is only available when you are using HTTPS.

It makes sense, I should have think of that.

thanks for your answer and for your time.

I have same issue Ctrl+C (copy), and Ctrl+X (cut) does not work when compiled to web assembly.

For debug run trunk serve it the provided explanation would be good enough. (is there easy way to enable it for debug?)

But for release trunk build --release --public-url wa/deck_info/ I use HTTPS https://jakub.bandola.cz/wa/deck_info/ So what else can be the issue?

You need RUSTFLAGS="--cfg=web_sys_unstable_apis" trunk serve. I've updated the instructions in https://github.com/emilk/eframe_template/

As a temporary workaround,
create .cargo/config.toml file with the following contents

[build]
rustflags = ["--cfg=web_sys_unstable_apis"]

which should add the flag automatically
