* Implement a "scanner" that reads the format string, maintaining state
* Split json_vnpack() to three separate functions for packing objects,
arrays and simple values. This makes it more clear what is being
packed, and the object and array structures become more evident.
* Make the skipping of ignored character simpler, i.e. skip ':' and
',' independent of their context
This patch shaves around 80 lines of code from the original
implementation.
This patch adds two new fields to the json_error_t struct: column and
source. It also adds functions to populate json_error_t internally.
The column field is not currently used, but it will be utilized in the
decoder and pack/unpack functions.
After looking at the new code for a few days, I didn't like it
anymore. To prepare for the future, a few fields will be added to the
json_error_t struct later.
This reverts commit 23dd078c8d. Some
adjustments were needed because of newer commits.
json_int_t is typedef'd to long long if it's supported, or long
otherwise. There's also some supporting things, like the
JSON_INTEGER_FORMAT macro that expands to the printf() conversion
specifier that corresponds to json_int_t's actual type.
This is a backwards incompatible change.
Replace all occurences of unsigned int and unsigned long with size_t.
This is a backwards incompatible change, as the signature of many API
functions changes.
With this encoding flag, the object key-value pairs in output are in
the same order in which they were first inserted into the object.
To make this possible, a key of an object is now a serial number plus
a string. An object keeps an increasing counter which is used to
assign serial number to the keys. Hashing, comparison and public API
functions were changed to act only on the string part, i.e. the serial
number is ignored everywhere else but in the encoder, where it's used
to order object keys if JSON_PRESERVE_ORDER flag is used.
Added functions are:
* json_string_nocheck()
* json_string_set_nocheck()
* json_object_set_nocheck()
* json_object_set_new_nocheck()
These functions don't check that their string argument is valid UTF-8,
but assume that the user has already performed the check.
It's now an error to try to add an object or array to itself. The
encoder checks for circular references and fails with an error status
if one is detected.
