The osm package requires json-parse-string which is not built-in to
Emacs, as far as I can see.  Should the package indicate requirements
and/or auto-install them if using package-install?

Ignore noise: it seems I need to actually build Emacs with json support.

As far as I know, it is included in emacs, unless emacs was compiled 
with --without-json or --without-all.

If the function is missing, as it is a C function, I don't know if there 
is a drop-in elisp replacement one could install as a fallback.

Best wishes,

Thibaut

Ah, true but only if the requisite library is available as well!  I had
to delve into the configure script to figure out I needed to install the
jansson dev package.

All good now.

Thank you,
eric

PS - osm is fantastic!  yet another thing I can do in Emacs.

But osm should be fixed to fall back to using json-read-from-string in
that case.

There is an Elisp library `json.el` that comes with Emacs, which is also available in Emacs 26 (and perhaps earlier versions, dunno). But it's not a drop-in replacement, because the functionality of the two isn't entirely equivalent (and function names are different). So if `osm` isn't set up to work with it as an alternative, native json support is gonna be necessary.
