Action Completer
A fairly simple method for registering callables as prompt-toolkit completions
from pathlib import Path
from action_completer import ActionCompleter
from prompt_toolkit.shortcuts import prompt
from prompt_toolkit.completion import PathCompleter
from prompt_toolkit.validation import Validator
completer = ActionCompleter()
@completer.action("cat")
@completer.param(
PathCompleter(),
cast=Path,
validators=[
Validator.from_callable(
lambda p: Path(p).is_file(),
error_message="Path is not an existing file"
)
]
)
def _cat_action(filepath: Path):
with filepath.open("r") as file_handle:
print(file_handle.read())
prompt_result = prompt(
">>> ",
completer=completer,
validator=completer.get_validator()
)
completer.run_action(prompt_result)
