Tools to Hyphenate Strings Using the ‘Hunspell’ Hyphenation Library

Description

Identifying hyphenation points in strings can be useful for both text processing and display functions. The ‘Hunspell’ hyphenation library https://github.com/hunspell/hyphen provides tools to perform hyphenation using custom language rule dictionaries. Many hyphenation rules dictionaries are included. Words can be hyphenated directly or split into hyphenated component strings for further processing.

Special thanks to

• @daroczig & @edwindj for language testing.

What’s Inside The Tin

The following functions are implemented:

• cleanup: Cleanup after ourselves
• curr_dict: Identify current hyphen rules language
• hyphenate: Hyphenate a character vector of words
• hyphendict_is_loaded: Test to see if the hyphenation language rules dictionary is loaded
• list_dicts: List available hyphenation languages rules
• switch_dict: Switch hyphen rules language
