ttok is showing a UserWarning coming from the click library reporting that --tokens is used more than once:
$ ttok --version

ttok, version 0.3
# What I think is the root cause
Click is generating this warning because the parameter `--tokens` has been registered for two **different** actions (`encode_tokens` and `as_tokens`):
```
@click.option("encode_tokens", "--encode", "--tokens", is_flag=True, help="Output token integers")
@click.option("as_tokens", "--tokens", is_flag=True, help="Output full tokens")
```
Based on the examples from the help `--tokens` behavior aligns with `as_tokens`(_Output full tokens_) and not with that of `encode_tokens` (_Output token integers_) so we should remove `--tokens` from `click.option("encode_tokens"`
Here's the help:
>To view token integers:
>
> cat input.txt | ttok --encode
>
>[...]
>To see the details of the tokens:
>
> ttok "hello world" --tokens
>
> Outputs:
>
> [b'hello', b' world']

Side note: Gemini Pro 2.5 detected the root cause of the issue (I just pasted the warning to it with nothing else) and ChatGPT helped me propose a sane fix. I was the chief editor :-D |

What I think is the root cause
Click is generating this warning because the parameter
--tokenshas been registered for these two different actions:Based on the examples from the help, the behavior of
--tokensaligns with the second action ("Output full tokens") and does not align with the first one ("Output token integers"). Thus we should remove--tokensfrom the first one.Here's the help:
P.S.
Simon, many thanks for the tools and your excellent blog
