@simonw any chance you would accept this? Running ttok is pretty noisy with this warning from click.

Usage: ttok [OPTIONS] [PROMPT]...

  Count and truncate text based on tokens

  To count tokens for text passed as arguments:

      ttok one two three

  To count tokens from stdin:

      cat input.txt | ttok

  To truncate to 100 tokens:

      cat input.txt | ttok -t 100

  To truncate to 100 tokens using the gpt2 model:

      cat input.txt | ttok -t 100 -m gpt2

  To view token integers:

      cat input.txt | ttok --encode

  To convert tokens back to text:

      ttok 9906 1917 --decode

  To see the details of the tokens:

      ttok "hello world" --tokens

  Outputs:

      [b'hello', b' world']

Options:
  --version               Show the version and exit.
  -i, --input FILENAME
  -t, --truncate INTEGER  Truncate to this many tokens
  -m, --model TEXT        Which model to use
  --encode, --tokens      Output token integers
  --decode                Convert token integers to text
  --tokens                Output full tokens
  --allow-special         Do not error on special tokens
  --help                  Show this message and exit.
