流式解析器(Streaming Parsers)如Jackson的JsonParser和Gson的JsonReader,允许开发者在解析JSON时按需读取数据,而不是一次性加载整个文档。这种方式不仅节省了内存,还大大提高了解析效率,尤其适合处理大型JSON文件。 二、Jackson的JsonParser:深入剖析 Jackson是Java世界中最受欢迎的JSON处理库之一,它的流式解析器JsonParse...

A fast streaming JSON parser for Python NAYA is designed to parse JSON quickly and efficiently in pure Python 3 with no dependencies. NAYA is different from other JSON parsers in that it can be used to stream a JSON array, even if the entire array is not yet available. Usage stream_array...
streaming-json-py 来了~ python 纯python版本。不依赖任何第三方库。这次移植到python 是直接把 golang 代码喂给 GPT4,然后人工修正后得到的。(GPT4超过200行代码就偷懒,所以大部分时间都花在了将分割转换后的代码拼起来...)。已上传到了PyPI,可以直接 pip install streamingjson 体验~。本库仍然聚焦补全LLM流...

The default representation uses a strict schema per parser and converts known numbers to int/float JSON values. Certain known values of None are converted to JSON null, known boolean values are converted, and, in some cases, additional semantic context fields are added....

I've written multiple JSON parsers before, maybe one can be salvaged there?: - I redid the lexer to be an iterator for QAPI - I know I used the Python AST stuff to prototype one once Is it somehow possible to write a streaming parser that can be re-used both by QAPI in sync cod...
