Hide links, tables, images, and alignment buttons

[Oren-Lindsey]

I need to hide the links, tables, images, and alignment buttons, as my app can't support them, and there doesn't seem to be a way to do that. Thanks.

Oh, and I need to be able to disable all the header options except h2

There is some limited guidance on how to do this, per https://github.com/stevengharris/MarkupEditor#customizing-the-toolbar, but you have to sort it out from ToolbarContents.swift for the details. Here is a version of AppDelegate.init in the SharedDemo folder that does some of what you want:

override init() {
    MarkupEditor.style = .compact
    let myToolbarContents = ToolbarContents(
        insert: false,    // Remove the insert toolbar that allows links, images, and tables
        styleContents: StyleContents(dent: false).   // Remove the indent/outdent button
    )
    ToolbarContents.custom = myToolbarContents
}

I hadn't thought about limiting the styles themselves to some kind of subset. Probably the easiest way to do that would just be to fork the code and modify StyleContext.swift so that it only contains the items you want, like:

    public static let AllCases = [Undefined, Multiple, P, H2]
    public static let StyleCases = [P, H2]
    public static let SizeCases = [P, H2]  // In order smallest to largest

While you're at it, you could change the name used in the menu so it looks more like what you might want (since "Header H2" is a little weird when there is only one style other than "Normal":

    public static let H2 = StyleContext(tag: "H2", name: "Header", fontSize: 24)

IIRC, the font sizes in this static are meaningless because they are controlled via markup.css as factors on apple-system-body.

FWIW, I'm interested in identifying things people need that really should be part of the API but which they're forced to take care of via a fork right now, so this was helpful to me. Don't go crazy with itemizing them, tho, please 😜.

I see that limiting the paragraph style options in StyleContext also requires a modification to MarkupMenu so that the menu works properly for Mac Catalyst if you care about it:

private func styleMenu() -> UIMenu {
    let children: [UICommand] = [
        UICommand(title: "Normal", action: #selector(MarkupWKWebView.pStyle)),
        UICommand(title: "Header", action: #selector(MarkupWKWebView.h2Style)),
    ]
    return UIMenu(title: "Style", children: children)
}

The UICommands here really should not be hardcoded and should just have adjusted based on the styles, I think, but I haven't really looked at this area for a long time.

Thanks for your help!
