Hi,
is there any news on this issue?
Hello, I could look into adding this!
However just so you know, custom types can be made easily. A type for bytes could be made like:
import typer
from typing_extensions import Annotated
app = typer.Typer()
class Bytes(self, value):
def __init__(self, value):
self.value = value.encode()
def parse_bytes(val):
return Bytes(val).value
def func(input: Annotated[Bytes, typer.Argument(parser=parse_bytes)]):
....
....
return
The greatest hassle with this solution is remembering to add `parser=parse_bytes' to all the Bytes arguments. So, could be worth natively supporting it.
This would also be useful for my use cases (firmware / transport protocols). Though, instead of supporting "bytes" directly, wouldn't we need to support "encodings"?
For example, a type specified as:
It seems to me that the only arg that would make sense for simply "bytes" would be python byte literals, with all their downsides.
Would be good to scope this to common encodings since there are thousands.

Description
It would be nice if we could add support for bytes in order to use it in contexts where bytes are expected (e.g. base64 encode/decode, password hashing, etc.)
Wanted Solution
Support for bytes type. Currently
typer
says:RuntimeError: Type not yet supported: <class 'bytes'>
Wanted Code
Alternatives
Always use encode/decode methods.
