How to control whether to generate inline list/map or not?

[FishHawk]

My data classes:

data class MetadataDetailDto(
    val authors: List<String>,
    val collections: Map<String, Map<String, ChapterMetadataDto>>,
)
data class ChapterMetadataDto(
    val name: String,
    val title: String,
)

I would like to generate files like this:

authors = [ "author1",  "author2"]

[collections.collection1]
chapter1 = {name = "name", title = "title"}

But it generates this:

[[authors]]
 = "author1"

[[authors]]
 = "author2"

[collections]
collection1.chapter1.name = "name"
collection1.chapter1.title = "title"

So is there a way to control whether to generate inline list/map or not?

Currently this is not possible. I'm thinking a good API for this might be something like a generateInline<T>(Boolean) function in the config block to control this type by type, as well as a similar function to set the default generation style. Would this be a good solution?

There is a small problem with this solution: types like Map/List may sometimes need to be inlined and sometimes don't. But I think it's fine to let users handle these themselves.

Also, I have some suggestions:

• Use inline style by default for better readability.
• Provide an interface to control whether to keep inline Map/List oneline.

By the way, thanks for your library. Without it, I would have to introduce a huge dependency just for TOML.

Separated the invalid TOML generation part into its own issue (#12), so this issue can focus on the configurability part.

c2678aa introduces an interface for configuring serialization. It doesn't yet allow per-type configuration yet, but otherwise it covers most aspects of table/inline/multiline syntax. What do you think?

It does not change the default to prefer inline syntax, mostly to avoid changing defaults people might have come to expect.

Closing as fixed since there seem to be no complaints about the merged solution.
