Crystal bindings for Hunspell.

Installation

Before installing crystal-hunspell ensure you have hunspell already installed:

1. Add the dependency to your shard.yml:

   dependencies:
     hunspell:
       github: mamantoha/crystal-hunspell
   

2. Run shards install

Usage

require "hunspell"

Open a dictionary:

hunspell = Hunspell.new("/usr/share/hunspell/en_US.aff", "/usr/share/hunspell/en_US.dic")

or

hunspell = Hunspell.new("en_US")

Ensure to close Hunspell instance after using.

hunspell.close

Below are some simple examples for how to use the repository.

Spelling

It's a simple task to ask if a particular word is in the dictionary.

hunspell.spellcheck("correct")
# => true

hunspell.spellcheck("incorect")
# => false

This will only ever return true or false, and won't give suggestions about why it might be wrong. It also depends on your choice of dictionary.

Suggestions

If you want to get a suggestion from Hunspell, it can provide a corrected label given a basestring input.

hunspell.suggest("arbitrage")
# => ["arbitrage", "arbitrages", "arbitrager", "arbitraged", "arbitrate"]

Suffix Match

hunspell.suffix_suggest("do")
# => ["doing", "doth", "doer", "dos", "do's", "doings", "doers"]

Stemming

The module can also stem words, providing the stems for pluralization and other inflections.

hunsell.stem("fishing")
# => ["fishing", "fish"]

Analyze

Like stemming but return morphological analysis of the input instead.

hunspell.analyze("permanently")
# => [" st:permanent fl:Y"]

Bulk Requests

You can also request bulk actions against Hunspell. Currently suggest, suffix_suggest, stem, and analyze are bulk requestable.

hunspell.bulk_suggest(["correct", "incorect"])
# => {"correct"  => ["correct", "corrects", "cor rect", "cor-rect"],
#     "incorect" => ["incorrect", "correction", "corrector", "injector", "correct"]}

hunspell.bulk_suffix_suggest(["cat", "do"])
# => {"cat" => ["cats", "cat's"],
#     "do"  => ["doing", "doth", "doer", "dos", "do's", "doings", "doers"]}

hunspell.bulk_stem(["stems", "currencies"])
# => {"stems" => ["stem"], "currencies" => ["currency"]}

hunspell.bulk_analyze(["dog", "permanently"])
# => {"dog" => [" st:dog"], "permanently" => [" st:permanent fl:Y"]}
