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.
In stream_get(), EOF never got it to stream->buffer and because of
this, stream_unget() failed on some situations. This patch makes
stream_get() handle EOF just like any other byte.
As a "side effect", lex_scan_string() now needs to unget the EOF, or
otherwise it ends up in error message on premature end of input.
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.
Don't alloca() a whitespace buffer and fill it with spaces in each
call to dump_indent. Instead, use a static whitespace buffer.
As a bonus, this saves the use of poorly portable alloca().
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.
Before, json_loads checked for '[' or '{' at the beginning. Now
there's a dedicated function for that: parse_json(). Also rename
parse() to parse_value().
