I just want to add another library in here which – at least in my world – is replacing json as the number one configuration and serialisation format. It's called libucl and it's main consumer is probably the new package tool in FreeBSD: `pkg`

Its syntax is nginx-like but can also parse strict json. It's pretty fast too.

The automatic array creation feature [1] seems misguided. It means that as a programmer consuming a configuration file, i can't know whether a given field will be a scalar or an array. I recently worked on a JavaScript API that had that behaviour, and it was a pain.

Apart from that, though, this looks like a really good format.

Out of curiousity, what do you mean by "my world"? Is this a particular domain you're working in, or just your personal usage?

He is obviously an alien and he is trying to introduce the tools he use in his home world.

OnTopic: I think is an unusual way of saying "the environment I use"

[jbergstroem]

Was just referring to the set of tools and libraries I surround myself with.

At one point I looked into using it, but there werent any python bindings at the time, and I didnt have the time (for the project) to write any. Are there any good language libs for it these days?

[jbergstroem]

Conveniently enough the first python extension landed in head 10 days ago: https://github.com/vstakhov/libucl/pull/68

oh nice! thanks for the link. :D

Any particular reason to use this over YAML for configuration?

[TillE]

Macros seem to be the key distinguishing feature. It's a good idea, sort of borrowing from template engines.

[crdoconnor]

Sure, but why not use a well known and solid templating engine if you're going to do templating?

Ansible combines YAML with jinja2 to do this type of stuff, for instance.

I'm not totally certain, but I think that might end up being simpler, more expressive and more powerful than this.
