can't compile examples

[wiiznokes]

hi, newbie here. I saw in an issue that i needed wasm-pack. So i installed it with this.

But now, i have this error:

Also, is this library only available for web with wasm or it also works on desktop ?

Hi! The issue seems to be coming from wrong cssparser version. I incorrectly had the version set at 0.31.* instead of to 0.31.0. I've made a fix and pushed to main. Please try again!

Also, the examples are now made to be built with trunk rather than directly with wasm-pack. Trunk is very simple; just install it and do

cd examples/web-todomvc
trunk serve

is this library only available for web with wasm or it also works on desktop ?

In the beginning there was a GTK4 version too. However, I decided to remove that for the time being. The concept behind Async UI is still quite new so I want to have one platform working well first.

I still get an error :cry:

Very strange. Can you make sure again that you have pulled the latest change (commit 3ab00b0), and that the file async_ui_web_macros/Cargo.toml has the line

cssparser = "0.31.0"

at the end?

If the error still persist, maybe try cargo clean?

[wiiznokes]

I made git pull so I should be fine. cargo clean show this:

cargo clean
warning: some crates are on edition 2021 which defaults to `resolver = "2"`, but virtual workspaces default to `resolver = "1"`
note: to keep the current resolver, specify `workspace.resolver = "1"` in the workspace root's manifest
note: to use the edition 2021 resolver, specify `workspace.resolver = "2"` in the workspace root's manifest

but it seems to work because i need to recompile the crates after. But i still get this error. Very strange indeed.

[wishawa]

I misunderstood how cargo handles semantic versioning. Commit fd8158f889fe22b9bf641cb26718ced0471238bc should fix the issue. Please try it!

well, i have this new error now :smile: (even with the last commit)

Seems to be a trunk issue. Can you try wasm-pack instead?

To build with wasm-pack, replace the content of index.html with this

<!DOCTYPE html>
<html>
<head>
	<meta content="text/html;charset=utf-8" http-equiv="Content-Type" />
</head>
<body>
	<script type="module">
		import init from './pkg/web_todomvc.js';
		init();
	</script>
</body>
</html>

Then run

wasm-pack build --dev --target web

Then you will have to serve the built content. I usually use microserver.

cargo install microserver
microserver

trunk serve works for me
