Emitting styles (and removing extra new lines)

[leoetlino]

Is it possible to configure the emitting style (block/flow and newlines)?

Currently, I have a bunch of existing YAML documents that look like this:

enemy:
- actors:
  - {name: Enemy_Bokoblin_Junior, value: 4.0} 
  - {name: Enemy_Bokoblin_Middle, value: 16.0} 
  - {name: Enemy_Bokoblin_Senior, value: 32.0} 
  - {name: Enemy_Bokoblin_Dark, value: 48.0} 
  species: BokoblinSeries 
# ...

Nice and readable, with the flow (inline) style being used for simple maps that don't contain nested maps (which is the PyYAML default).

Emitting the same document with ryml currently results in the following:

enemy:
  -
    actors:
      -
        name: Enemy_Bokoblin_Junior
        value: 4
      -
        name: Enemy_Bokoblin_Middle
        value: 16
      -
        name: Enemy_Bokoblin_Senior
        value: 32
      -
        name: Enemy_Bokoblin_Dark
        value: 48
    species: BokoblinSeries

which isn't that bad but it's comparatively harder to read and it's also a bit too long.

So to get back to the questions:

• Is it possible to get rid of the new line that is emitted for maps that are sequence items? For some reason, this only affects maps that are sequence items.

• Does ryml make it possible to set the flow style (block/inline) for maps and sequences? I was unable to find any such functionality in the API but it's possible I've missed something.

Sorry, there's no such functionality.

Absolutely, the newline shouldn't be there. So that's a bug indeed. I was under the impression that this was ok, but currently there is no unit test covering formatting, as the focus has been on semantic correctness. I'll have to verify what's going on. I'll start by adding some unit tests for formatting, and looking at the current emitter code (which is admittedly not very nice) to verify how to refactor to make it easier to customize emission.

@leoetlino The bug causing the newline was fixed. I'm going to open a separate issue to track emit formatting.

@leoetlino I opened #37 to start work on emit formatting. You seem to have some ideas (or requirements) and I'd be happy to have your input there.
