@staticmethod
def decode(data: bytes, *, lang: str = 'en', mode: str = 'display') -> str: (source) ¶

Decodes a byte stream into a string of tokens

Parameters
data:`bytes`	The token bytes to decode
lang:`str`	The language used in `string` (defaults to English, `en`)
mode:`str`	The form of token representation to use for output (defaults to `display`)
Returns
`str`	A string of token representations

@staticmethod
def encode(string: str, *, model: TIModel = None, lang: str = None, mode: str = None) -> bytes: (source) ¶

Encodes a string of token represented in text into a byte stream

For detailed information on tokenization modes, see tivars.tokenizer.encode.

Parameters
string:`str`	The text string to encode
model:`TIModel`	The model to target when encoding (defaults to no specific model)
lang:`str`	The language used in `string` (defaults to English, `en`)
mode:`str`	The tokenization mode to use (defaults to `smart`)
Returns
`bytes`	A stream of token bytes

def __format__(self, format_spec: str) -> str: (source) ¶

overrides tivars.var.TIEntry.__format__

Formats this entry for string representations

Parameters
format_spec:`str`	The format parameters
Returns
`str`	A string representation of this entry

def get_min_os(self, data: bytes = None) -> OsVersion: (source) ¶

overrides tivars.var.TIEntry.get_min_os

overridden in tivars.types.tokenized.TIAsmProgram

Determines the minimum OS that supports this entry's data

Parameters
data:`bytes`	The data to find the minimum support for (defaults to this entry's data)
Returns
`OsVersion`	The minimum `OsVersion` this entry supports

def get_version(self, data: bytes = None) -> int: (source) ¶

overrides tivars.var.TIEntry.get_version

Determines the version byte corresponding to given data for this entry type

Entries which could contain non-backwards compatible data are assigned a version byte. If an entry's version exceeds the "version" of a calculator, transfer to the calculator will fail.

Parameters
data:`bytes`	The data to find the version of (defaults to this entry's data)
Returns
`int`	The version byte for `data`

@Loader[bytes, bytearray, BytesIO]
def load_bytes(self, data: bytes | BytesIO): (source) ¶

overrides tivars.var.SizedEntry.load_bytes

overridden in tivars.types.tokenized.TIProgram

Loads a byte string or bytestream into this entry

Parameters
data:`bytes \| BytesIO`	The bytes to load

@Loader[str]
def load_string(self, string: str, *, model: TIModel = None, lang: str = None, mode: str = None): (source) ¶

overrides tivars.var.TIEntry.load_string

overridden in tivars.types.gdb.TIGraphedEquation, tivars.types.tokenized.TIProgram, tivars.types.tokenized.TIString

Loads this entry from a string representation

For detailed information on tokenization modes, see tivars.tokenizer.encode.

Parameters
string:`str`	The string to load
model:`TIModel`	The model to target when encoding (defaults to no specific model)
lang:`str`	The language used in `string` (defaults to English, `en`)

`list[Token]`	The tokens comprising this entry as a list of `Token` objects

clock_tokens: list[bytes] = (source) ¶

Tokens which interface with the RTC

These tokens influence the entry's version, though detecting the presence of the RTC has no current application.

min_data_length: int = (source) ¶

overrides tivars.var.SizedEntry.min_data_length

overridden in tivars.types.gdb.TIGraphedEquation

The minimum length of this entry's data

If an entry's data is fixed in size, this value is necessarily the length of the data

versions: list[int] = (source) ¶

overrides tivars.var.TIEntry.versions

The possible versions of this entry
