The best thing about macos is the dictionaries accessible from dictionary.app. Is there a way to convert them to a format that is usable on other platforms as well (such as the dict format or the stardict format)?
Alternatively, is there a way to extract them into a plain text format? (How are they stored anyway and where?)
PS There is this
for extracting word lists. Perhaps it could be changed to extract the whole dictionaries as well?
