Marvin Humphrey updated LUCY-74:
--------------------------------
Attachment: json_support.diff
Json.c
Json.bp
Lucy::Util::Json supplies four functions:
* to_json
* from_json
* spew_json
* slurp_json
The to_json() and from_json() functions operate on strings, and throw
exceptions if anything goes wrong. The spew_json() and slurp_json() fuctions
operate on a Folder and a filepath; they set Err_error and return false/NULL
when something is awry, allowing internal C calling code to handle error
conditions.

> Lucy will store most index metadata as JSON, so we need a JSON
> encoder/decoder. Eventually, we should write our own, but for now, this patch
> supplies an API and leaves it up to the binding to fill in an implementation.
> The supplied Perl binding implementation uses the CPAN module JSON::XS and
> translates back and forth between Perl scalar-hash-array data structures and
> Lucy CharBuf-Hash-VArray data structures.
