- 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.
That is, test cases where there's no newline or other whitespace at
the beginning or end of input. This was implemented by adding a
--strip option to split-testfile to strip the input file after writing
it.
The actual test JSON texts are the same as testdata/invalid and
testdata/valid. The expected output of the invalid cases had to be
adjusted a bit: because there's no newline at the end, some of the
line numbers needed to be changed.
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.
Before, only the syntax level (parse_*) was able to set the error
string. This patch fixes the situation so that lexical (lex_*) and
stream (stream_*) levels can report detailed error messages.
Also, instead of 0, EOF is now returned by stream on error.
It's no longer needed to load the whole input into a string and then
parse from the string. Instead, the input is read as needed from
a string or file.
