+# re-type-on-error
+
+## description
+A plugin for [oh-my-zsh](#https://github.com/ohmyzsh/ohmyzsh/) that watches for
+ failed commands(=commands with a non-zero exit code). If a command failed in t
+he interactive shell, it get immediately re-typed, or maybe call it re-displaye
+d to the user for possible corrections.
+
+## showcase
+![showcase](showcase.gif)

+
+## configuration

+### environment variables

++ that the previous command failed
++ the exit code of the previous command
++ the default of this setting is true as indicated above, simply set to false
