Utilities for Chakobsa scripts. Implements {{chak-from-root}}.
Exposed functions
l(term, face, alt)- Creates a link to a Chakobsa lexeme - similar to
{{l|chak|term}}
is_geminate(char)- returns true if the supplied 'character' is geminate
compress_consonants(str)- Returns a 'compressed' version of the string where consonant digraphs are reduced to a single character and trigraph geminates are reduced to a geminate of a single character. Mostly for use with other functions for parsing.
expand_consonants(str)- Returns an 'expanded' version of the string where reductions from
compress_consonantsare replaced with the original romanizations.
parse_consonants(str)- Returns a string where the consonants have been split out, delimited by hyphens. Understands geminate consonants and considers them a 'single' consonant.
parse_root(root_str,expandFinal)- Returns a table of parts of the root string is grouped by consonant and vowels. Example: "kkaalatg" > "kk","aa","l","a","tg". If expandFinal is true, returns the final part parsed out through
parse_consonantsThe above example would be "kkaalatg" > "kk","aa","l","a","t-g". Used for inflection functions.
