In hyphenatr: Tools to Hyphenate Strings Using the 'Hunspell' Hyphenation Library

hyphenatr : HY-PHEN-ATE ALL THE THINGS

Based on the Hunspell hyphenation library and includes hyphenation rules dictionaries from LibreOffice. See the <inst/COPYRIGHTS> file for individual copyright information.

The following functions are implemented:

• curr_dict: Identify current hyphen rules language
• hyphenate: Hyphenate a character vector of words
• list_dicts: List available hyphenation languages rules
• switch_dict: Switch hyphen rules language

Special thanks to

• @daroczig & @edwindj for language testing.

News

• Version 0.3.0.9000 - Copyrights & more hyphenation rules added
• Version 0.2.1.9000 - CRAN checks passed
• Version 0.2.0.9000 - no external library required
• Version 0.1.0.9000 released
