Implement option to write sequences out in flow stlye for only certain fields with primitive arrays about yamldotnet HOT 13 CLOSED

Is there documentation on how to implement your own visitor pattern during implementation or intercept the event emitter such that you can define a style (flow or block) for a particular field in the object graph?

from yamldotnet.

I was able to set the sequence style to flow only on primitive arrays by adding this code to the VisitSequenceStart() method in AnchorAssigningObjectGraphVisitor class. However, there should be a better way to do this, perhaps making it easier to pass in your own visitor when instantiating the serializer class.

if (sequenceType.IsArray && elementType.IsPrimitive)
{
info.Style = Core.Events.SequenceStyle.Flow;
}

The Serializer class is meant to be a simple facade for the various classes that collaborate to the serialization process. However, it is still work in progress and that's the reason why it is not yet possible to alter the visitors that will be used, but this feature is definitely on top of the list. Your requirement of emitting arrays as flow sequences is the kind of usage that I had in mind when I started this refactoring.

Now that version 2.0.0 is out, I think we should work on making the Serializer more extensible. I will keep you comments in mind while working on it. Thanks

Is flow style for sequences implemented in the current version? I was using YamlDotNet to dump objects but since I've got a few relatively large byte arrays it is making the dump next to unreadable (which defeats the purpose of Yaml :-) ) I was expecting something in SerializerOptions but didn't find anything, then stumbled on this issue. Any news?

Is it there yet, or does anyone have some sort of hack/fix? Much appreciated.

Anyone stumbling upon this, I was able to do it with this fork https://github.com/xoofx/SharpYaml

You then apply this attribute on the fields you want to have a different style:
[SharpYaml.Serialization.YamlStyle(YamlStyle.Flow)]

@mathiassiig Is it possible to submit this as a pull request to the main branch? Especially with GitHub Actions YAML using this in places, it would be useful to have this functionality.

This issue appears to be abandoned, I'm going to close it. I believe this is already implemented.

from yamldotnet.

I can't see any information in this issue or linked issues that this is implemented. Is it, and if so, how can it be accomplished?

Also, is there any way to set max line length for flow-style arrays (making them break when the max length has been reached)?

from yamldotnet.

We don’t have a way of doing that in yamldotnet that I’m aware of. We’re very grateful for pull requests if you want to create one.

from yamldotnet.

Thanks. Unfortunately swamped. I found a (hacky?) workaround: In Visit(YamlSequenceNode sequence), check the NodeType of the items of the sequence and check if they are YamlNodeType.Scalar.

In any case, it seems this issue was closed erroneously then. You may consider opening it, for clarity.

I closed because there was no comment for 3 years.
