Insert Duplicate Section?

[theonewolf]

I am testing support for duplicate sections, and I can not figure out how to add a new section with the same name as an old section. I actually don't think it's exposed in your API currently.

Parsing duplicate sections from files works fine, but adding same named sections does not (using with_section). I recommend adding a new method for instantiating sections, or a boolean on with_section that flags creation of a section--not retrieval / insertion into a pre-existing section.

@zonyitoo very close to having full support for #49! Instead of re-opening it, I figured I'd file another bug report.

Hmm, I didn't add that because with_section was defined for insert or modify the section that is already existed.

Consider using the entry API:

let mut ini = Ini::new();
match ini.entry(Some("KeyDuplicated")) {
    SectionEntry::Vacant(mut vac) => {
    }
    SectionEntry::Occupied(mut occ) => {
        // Append a new section with the same name
        occ.append(...);
    }
}

@zonyitoo thanks for the tip, I'll let you know if it covers my use case and close this out. Yes, with your API and how things work it did feel odd adding in what I described.

I really wish systemd used a standard configuration format vs rolling their own.

@zonyitoo @theonewolf I am also working with systemd files and run into this issue. Is the above workaround still the recommended way to achieve this?

[zonyitoo]

Maybe, I haven't thought about it since the last discussion.

What came to mind was to look for a function like with_new_section that behaves like with_section but always opens a new section when called.

I'm not sure if this makes sense from your API design, but it would be similar to how I can add duplicate keys using append instead set.
