But to the best of my knowledge we didn't, so I'd just leave them out for now. > diff --git a/json-writer.h b/json-writer.h > index 04413bd1af..aa513e86cb 100644 > --- a/json-writer.h > +++ b/json-writer.h > @@ -69,42 +69,175 @@ struct json_writer > .open_stack = STRBUF_INIT, \ > } > > +/* > + * Initialize a json_writer with empty values. > + */ > void jw_init(struct json_writer *jw); > + > +/* > + * Release the internal buffers of a json_writer. > + */ > void jw_release(struct json_writer *jw); > > +/* > + * Begin the json_writer using an object as the top-level data structure.

Is it mandatory to call it? Can it be nested? Why is there no corresponding `jw_object_end()`? > +/* > + * Begin the json_writer using an array as the top-level data structure.

E.g. can you call `inline_begin_object()` multiple times? > +/* > + * Append a string value to the current array of the json_writer. > + */ > void jw_array_string(struct json_writer *jw, const char *value); Same question here as above: what happens when called after `jw_object_begin()`? > +/* > + * Return if the json_writer is terminated. In other words, if the all the s/if/whether/ Otherwise it reads as if the function wouldn't return in case it's not terminated. Patrick
