guile-json 4.2.0 released

guile-json 4.2.0 released

[Aleix Conchillo Flaqué]

Hi!

I'm happy to announce guile-json 4.2.0. This new version introduces a new
feature to allow converting a JSON object into a record type and vice
versa. This feature works well, for example, when creating REST APIs. The
code was originally obtained from GNU Guix (thank you Ludo!) and I added
the possibility to convert a record type into a JSON object added as well.

 https://github.com/aconchillo/guile-json/

* About

guile-json is a JSON module for Guile. It supports parsing and
building JSON documents
according to the http://json.org specification.

- Complies with http://json.org specification.
- Builds JSON documents programmatically using scheme data types.
- Allows JSON pretty printing.

That's quite a nice idea, no matter, where it is from and it is good to
know, that guile-json can do this.

 - Introduce (define-json-mapping) which allows converting a JSON object into
    a record type and vice versa. The initial code for this feature was copied
    from the GNU Guix project.
--8<---------------cut here---------------end--------------->8---

Nice!  :-)

There’s a bidirectional version here, but it’s slightly incompatible:

  https://gitlab.inria.fr/guix-hpc/guix-kernel/-/blob/master/jupyter/json.scm

It relies on (guix records), which is not great for Guile-JSON.

It looks like the surface API is different, but the internal json <-->
scheme records functionality overlaps... Any thoughts on whether
guile-json  would serve as the underpinnings of an implementation of
srfi-180?

With the current api, no. The code of guile-json could be used to implement srfi-180, but the current guile-json API could not efficiently implement srfi-180.

I am not Aleix, but I helped making it faster for the 4.0 release.

Hi!

I briefly looked at srfi-180, it seems I could take guile-json internals to
implement that srfi-180 API and then implement current guile-json API on
top of that. It would be nice to still support both.

Maybe I will give it a try at some point in the near future.

Nice! And thank you! I actually released guile-json 4.3.0 making [<=>
RECORD->JSON] optional as in the code you linked. If guix moves to
guile-json 4.3.0 I guess you could now remove guix/json.scm, unless you are
planning to use guix records there.

Best,

Aleix

Awesome, thank you!  We’ll probably move to Guile-JSON, at least in Guix
proper.
