Grammarify is a npm package that safely cleans up text that has mispellings, improper capitalization, lexical illusions, among other things.

How to use

var grammarify = require("grammarify");

var sentence = "im so   borrreeedddd";
console.log(grammarify.clean(sentence)); // "I'm so bored."

Features

Automatically add periods at the end of sentences

"I am a sentence" -> "I am a sentence."

Remove "safe" lexical illusions

(Some words are grammatically correct if repeated twice, words that are not are removed if duplicated)

"The the pig snorted." -> "The pig snorted."

Spellcheck words

"I was mad becuase I left home early." -> "I was mad because I left home early."

Capitalize words at the beginning of sentences

"I like to run. he runs faster than I." -> "I like to run. He runs faster than I."

Change SMS/shorthand to full words

"Meet me at home asap." -> "Meet me at home as soon as possible."

Shrink stretched words

"I'm so borreedddd." -> "I'm so bored."

Combine separated words

"Yesterday and to day we flew kites." -> "Yesterday and today we flew kites."

Split up sentences if connected

"Writing C# code is fun.It is much better than Java." -> "Writing C# code is fun. It is much better than Java."

Fix intended ellipsis

(Intended ellipsis are any two or more periods separated by any number of periods and/or spaces)

"I was thinking yesterday..that I should go outside." -> "I was thinking yesterday... that I should go outside."

Add spaces between comma/semicolon/colon-separated words

"She likes to eat,cook,clean and dance!" -> "She likes to eat, cook, clean and dance!"

Fix extra spaces in between words

"Wow  what an  extra long coat!" -> "Wow what an extra long coat!"

Fix duplicate punctuation

" what a daay. i must have had 1,,000 shots" -> "What a day. I must have had 1,000 shots."
