Add fuzzy search to environment variables

README.md

@@ -107,25 +107,24 @@ Setting these environment variables, you'll set options by default. For example:
 
 - FFIND_SORT: Return the results sorted. This is slower, and is mainly thought to ensure
               consistency on the tests, as some filesystems may order files differently
-- FFIND_CASE_SENSITIVE: Search is case sensitive. Equivalent to -c flag
-- FFIND_CASE_INSENSITIVE: Search is case insensitive. Equivalent to -i flag.
-- FFIND_SEARCH_HIDDEN: Search in hidden directories. Equivalent to --hidden flag.
-- FFIND_SEARCH_PATH: Search in the whole path. Equivalent to -p flag.
-- FFIND_IGNORE_VCS: Ignore paths in version control. Equivalent to --ignore-vcs
-- FFIND_NO_SYMLINK: Do not follow symlinks. Equivalent to --nosymlinks flag.
-- FFIND_NO_COLOR: Do not show colors. Equivalent to --nocolor flag.

-If the environment is present, when calling ffind -h, the option will display [SET] at the end.
