enchant.utils: Misc utilities for the enchant package
This module provides miscellaneous utilities for use with the enchant spellchecking package. Currently available functionality includes:
functions for dealing with locale/language settings
ability to list supporting data files (win32 only)
functions for bundling supporting data files from a build
- enchant.utils.get_default_language(default=None)
Determine the user’s default language, if possible.
This function uses the ‘locale’ module to try to determine the user’s preferred language. The return value is as follows:
if a locale is available for the LC_MESSAGES category, that language is used
if a default locale is available, that language is used
if the keyword argument <default> is given, it is used
if nothing else works, None is returned
Note that determining the user’s language is in general only possible if they have set the necessary environment variables on their system.
- enchant.utils.levenshtein(s1, s2)
Calculate the Levenshtein distance between two strings.
This is straight from Wikipedia.
- enchant.utils.trim_suggestions(word, suggs, maxlen, calcdist=None)
Trim a list of suggestions to a maximum length.
If the list of suggested words is too long, you can use this function to trim it down to a maximum length. It tries to keep the “best” suggestions based on similarity to the original word.
If the optional “calcdist” argument is provided, it must be a callable taking two words and returning the distance between them. It will be used to determine which words to retain in the list. The default is a simple Levenshtein distance.
