Code

MudButton'() {
    style { displayInlineBlock }
    Disabled isLoading
    OnClick(fun _ -> task {
        setIsLoading true
        do! hook.DownloadTransactionReports()
        setIsLoading false
    })
    i18n.tran "Common.BtnDownload"
}

Result

MudButton'() {
    style { displayInlineBlock }
    Disabled isLoading
    OnClick(fun _ -> task {
        setIsLoading true
        do! hook.DownloadTransactionReports()
        setIsLoading false
    }
    )

_{Did you know that you can ignore files when formatting from fantomas-tool or the FAKE targets by using a .fantomasignore file?}

Hello, on paper this sounds reasonable.

However, a lot will depend on the implementation. I would accept a PR if it can be solved in an elegant way. If there is too much church to get this right, this would be an acceptable limitation.

Are you interested in submitting a proposal PR?

Sorry, it maybe too complex to me.

Please elaborate on what might be too complex for you.
We are working on a new documentation initiative #2315 and hope to encourage people to contribute.
A lack of knowledge of this project nor the F# language should not be a bottleneck.
I'm curious to find out what is too complex about this or why you immediately assume this.
