JSON parser written in nasm for x86-64 Linux

asmjson

JSON parser written in assembly (x86-64 nasm to be specific).

See the C header for program signature. In general json_parse is used to parse JSON data, and after the end of processing json_dealloc is used to free memory allocated for strings, arrays and objects.

Limitations

• Unicode escape sequences in strings (\uHHHH) are not supported (TODO: add support for those)
• Only numbers up to 255 digits are supported
• Only numbers understood by strtol or strtod can be correctly parsed
• JSON data must be provided as a FILE*. POSIX fmemopen can be used for parsing strings.

Otherwise, asmjson should be able to parse any valid JSON file.

Tests

$ ./build_tests.sh
$ ./run_tests.sh

Tests are run on their own first, to see if everything works correctly. Afterwards, they are run again with valgrind to check for any memory leaks.
