hacky spellcheck that uses rules from languagetool and suggests corrections

spellcheck_en.py

#!/bin/env python3

# this needs https://github.com/bminixhofer/nlprule to work:
# pip install nlprule

from nlprule import Tokenizer, Rules
from sys import argv

LANG = "en"

input_string = []

args = argv[1:]
if args:
    input_string.extend(args)  # first read in all args to parse them as string later

text = list(filter(None, map(str.strip, input_string)))  # split & strip & whitespace

rules = Rules.load(LANG, Tokenizer.load(LANG))

for line in text:
    print(line)

    for s in rules.suggest(line):
        print(f"{s.start * ' '}{(s.end - s.start) * '^'} {s.replacements}: {s.message}")

    print("")
