DESCRIPTION ENVIRONMENT COMPLETE_UTIL_TRACE => bool If set to true, will display more log statements for debugging. COMPLETE_UTIL_LEVENSHTEIN => str ('pp'|'xs') Can be used to force which levenshtein implementation to use. The default is to use XS version from Text::Levenshtein::XS if that module is installed, otherwise fallback to the included PP implementation (which is about 1-2 orders of magnitude slower). SEE ALSO Complete If you want to do bash tab completion with Perl, take a look at Complete::Bash or Getopt::Long::Complete or Perinci::CmdLine. Other Complete::* modules.
