Project description

✨ pybase16384 ✨

The python binding for base16384

一种神奇的编码

python implementation wheel license action

使用

编码/解码文本

>>> import pybase16384 as pybs
>>> pybs.encode_string('hello!!')
'栙擆羼漡'
>>> pybs.decode_string('栙擆羼漡')
'hello!!'

编码文件

from io import BytesIO

import pybase16384 as pybs

with open("input.pcm", "rb") as f:
    data = f.read()
for i in range(1):
    pybs.encode_file(BytesIO(data), open("output2.pcm", 'wb'), True)

解码文件

from io import BytesIO

import pybase16384 as pybs

with open("output2.pcm", "rb") as f:
    data = f.read()
for i in range(1):
    pybs.decode_file(BytesIO(data), open("input2.pcm", 'wb'))

公开函数

def encode_len(dlen: int) -> int: ...

def decode_len(dlen: int, offset: int) -> int: ...

def encode(data: bytes) -> bytes: ...

def decode(data: bytes) -> bytes: ...

def decode_file(input: BinaryIO, output: BinaryIO, buf_rate: int = 10) -> None: ...

def encode_file(input: BinaryIO, output: BinaryIO, boolwrite_head: bool = False, buf_rate: int = 10) -> None: ...

def encode_from_string(data: str, write_head: bool = False) -> bytes: ...

def encode_to_string(data: bytes) -> str: ...

def encode_string(data: str) -> str: ...

def decode_from_bytes(data: bytes) -> str: ...

def decode_from_string(data: str) -> bytes: ...

def decode_string(data: str) -> str: ...

write_head将显式指明编码出的文本格式(utf16be)，以便文本编辑器(如记事本)能够正确渲染，一般在写入文件时使用。
buf_rate指定读取文件的策略。当它为n时，则表示一次读取7n或者8n个字节。如果读到的字节长度小于预期，则说明长度不够，此时，n将减半，恢复文件指针，重新读取。如果当n=1时长度仍然不够，就地encode/decode处理之。
encode_len和decode_len用于计算输出的长度

内部函数

他们直接来自底层的C库，高性能，但是一般不需要在外部使用（除非是增加性能）

def _encode(data: BufferProtocol) -> bytes: ...

def _decode(data: BufferProtocol) -> bytes: ...

def _encode_into(data: BufferProtocol, dest: BufferProtocol) -> int: ...

def _decode_into(data: BufferProtocol, dest: BufferProtocol) -> int: ...

_decode在解码b'='开头的数据时不安全：解释器异常
_encode_into和_decode_into直接操作缓冲区对象的底层指针，0拷贝，当然也和上面一样的问题，他们是没有检查的
