Couldn't work screenshot (Alt+1, Alt+3) in web app

[hadamak]

as is:
Alt + 1 or Alt + 3 cause freeze in web app.

to be:
I want to download screenshot pictures.

environment:
https://kitao.github.io/pyxel/wasm/examples/script_test.html and others.
-Microsoft Edge or Firefox
-Windows11

In the latest Pyxel, I suppressed crashing error when capture functions are used.

To enabled capture functions on the web like other platforms, the chrono crate of Rust should work on the web and I also need to come up with a way to download save file in Emscripten file system.

@kitao
chrono version above 0.4.20 should work on emscripten target. chronotope/chrono#568

Doesn't it works?

[kitao]

@km19809 It can be compiled. But when I called chrono::Local::now() with Emscripten, it crushed.

[kitao]

I tried chrono::Local::Now() at the beginning of Pyxel code for test.
The error message was
pyo3_runtime.PanicException: cannot call wasm-bindgen imported functions on non-wasm targets

[km19809]

It's weird because chrono::Local::now() should target this function.
So wasm-bindgen is not needed.
I first assumed that wasmbind feature of chrono is the problem.
However, even after I modified chrono attribute of cargo.toml, it crashed. (Uncaught 16664952)

[dependencies]
array-macro = "2.1"
chrono = {version = "0.4.22", default-features = false, features = ["clock", "std"]} # `wasmbind` is one of default-features.
# ...

I don't understand why.

In the latest version of Pyxel on the web, you can save the output file.

I became able to do that. Thank you for your nice work.
