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.
All decoding functions now accept a json_error_t** parameter and set
it to point to a heap-allocated json_error_t structure if an error
occurs. The contents of json_error_t are no longer exposed directly, a
few functions to do it have been added instead. If an error occurs,
the user must free the json_error_t value.
This makes it possible to enhance the error reporting facilities in
the future without breaking ABI compatibility with older versions.
This is a backwards incompatible change.
As of now, the parameter is unused, but may be needed in the future.
I'm adding it now so that in the future both API and ABI remain
backwards compatible as long as possible.
This is a backwards incompatible change.
This is to free up bits from the flags parameter of json_dump
functions. I'm pretty sure no-one needs 256 spaces of indentation when
pretty-printing JSON values...
This is a backwards incompatible change.
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.
Couple some string and number information from the RFC conformance
chapter in the API reference, and refer to the RFC conformance chapter
from API reference for more information.
Also, state more clearly that a JSON text must have an array or object
as the top-level value, and better document the string comparison
performed by json_equal().
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.
Provide an example usage pattern for reference stealing functions.
This way the user (hopely) sees more clearly how the reference
stealing functions are meant to be used.
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.
- Never append newline to output
- By default, add spaces between array and object items for more
readable output
- Introduce the flag JSON_COMPACT to not add the aforementioned spaces
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.
Added functions:
json_string_set
json_integer_set
json_real_set
While at it, clarify the documentation and parameter naming of
json_{string,integer,real}_value() a bit.
Some day we will have ANSI C compatibility... This change doesn't make
the API backwards incompatible because uint32_t was only used in flags
to json_dump*() and the flags are meant to be used only by ORing
constants and macro output, and actually currently only JSON_INDENT
can be used.
Constructors are described more clearly and return values on error
situations more compehensively. Also add an example of the object
iteration protocol.
All pointer arguments are now tested for NULL. json_string() now also
tests that strdup() succeeds. This is to ensure that no NULL values
end up in data structures.
Also desribe the different sources of errors in documentation.
