Describe your use case
As I found out, cargo use a custom parsing for, e.g., --features by splitting each argument with comma and whitespace and then flattening an array of the split stuff (if flag was used several times).
That is despite using clap, which does have value_delimiter. However, you can only split using a single char (or even string?) right now. In Dioxus, there are several places where splitting works and doesn't work automatically. Some of this is probably due to downstream further parsing, like with --features that is sent to cargo through Command.
Describe the solution you'd like
I want to be able to write value_delimiter = [' ', ','] and get all the split arguments to be concatenated into a single Vec<String>, automatically being flattened. This provides great flexibility in how you can pass arguments to the same flag.
Alternatives, if applicable
The only alternative would be this.
