|
+# This is a implementation of per directory history for zsh, some
|
|
|
+# implementations of which exist in bash[1,2]. It also implements
|
|
|
+# a per-directory-history-toggle-history function to change from using the
|
|
|
+# directory history to using the global history. In both cases the history is
|
|
|
+# always saved to both the global history and the directory history, so the
|
|
|
+# toggle state will not effect the saved histories. Being able to switch
|
|
|
+# between global and directory histories on the fly is a novel feature as far
|
|
|
+# as I am aware.

|
