How about adding json decode and encode function about penlight

[alerque]

There are several good options for JSON libraries available in the Lua ecosystem, including pure Lua variants. There are several trade offs to be made and different ones might be better for different projects (e.g. for my use cases the C based faster ones are typically better). I don't think re-inventing that wheel in this project would be particularly beneficial.

IMHO, XML/JSON/YAML/etc are a full time job to maintain.
I recommend to discuss and list one or multiple projects that we can recommend to people needs them.

About json, as pure Lua solution, I recommend lunajson against the most known dkjson (see benchmarks)

[alerque]

One could argue than if JSON is one full time job then YAML is a dedicated team and XML is a department. We're already dropping our home grown XML things for related reasons, I don't think we need to make that mistake twice.

But yes, your references on replacements are good. dkjson for flexibility to go with C based LPEG or pure Lua (and for it's penetration into existing projects, but if you know exactly what you need and why cjson for speed or lunajson for pure Lua are good recommendations.

I feel the same, we’re about to drop XML from penlight. So adding JSON would not make sense imo.

Let’s close this.
