Module `test_json_parser` ========================= This module contains two programs for testing the json parsers. - `test_json_parser_incremental` is for testing the incremental parser, It reads in a file and passes it in very small chunks (default is 60 bytes at a time) to the incremental parser. It's not meant to be a speed test but to test the accuracy of the incremental parser. The option "-c nn" specifies an alternative chunk size, "-r nn" runs a range of chunk sizes down to one byte on the same input (with output separated by null bytes), and "-s" specifies using semantic routines. The semantic routines re-output the json, although not in a very pretty form. The required non-option argument is the input file name. - `test_json_parser_perf` is for speed testing both the standard recursive descent parser and the non-recursive incremental parser. If given the `-i` flag it uses the non-recursive parser, otherwise the standard parser. The remaining flags are the number of parsing iterations and the file containing the input. Even when using the non-recursive parser, the input is passed to the parser in a single chunk. The results are thus comparable to those of the standard parser. The sample input file is a small, sanitized extract from a list of `delicious` bookmarks taken some years ago, all wrapped in a single json array.
