Accessing files and directories?

It seems the current working directory is /, in ruby.wasm. By default this appears
to be empty - I tried via Dir['*'].

I also don't seem to be able to create anything, or read from files.

I'd love to be able to do both, but reading from a file is more important. My initial
idea was to "componentize" my smaller gems into Strings that can be evaluated
via ruby.wasm. But if I can not read any file or find them then this strategy does
not work.

Is there a way to query a file's content still? Even javascript has that option available
at the least if you e. g. place a .js file onto the webserver and then load it locally.

Right now I am not sure how to do this via ruby.wasm which kind of limits the way
I can use it. At any rate, thank you for reading this.

ソースファイルもテストも指定されていません。まず、ruby.wasm が WASI ファイルシステムへのアクセスをどのように公開しているか、また現在の作業ディレクトリで Dir['*'] がどのように動作するかを追跡し、サポートされている読み取りと作成のセマンティクスを特定してください。Issue のファイルアクセスに関する期待事項が実装され、適切なテストでカバーされるか、制限事項が明確に文書化されていれば完了です。
