[Per-Directory-History][6]
=========================
Per directory history for zsh, as well as global history, and the
ability to toggle between them with ^G.
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.
This is a standalone repository for the script, however it is also included in
[oh-my-zsh][4] as a plugin.
----------------------------------------------------------------------------
Usage
----------------------------------------------------------------------------
1. Load this script into your interactive ZSH session:
% source zsh-per-directory-history.zsh
2. The default mode if per directory history, interact with your history as normal.
3. Press ^G (the Control and G keys simultaneously) to toggle between local
and global histories.
-------------------------------------------------------------------------------
Configuration
-------------------------------------------------------------------------------
* HISTORY_BASE a global variable that defines the base directory in which the
directory histories are stored
* per-directory-history-toggle-history is the function to toggle the history
-------------------------------------------------------------------------------
History
-------------------------------------------------------------------------------
The idea/inspiration for a per directory history is from [Stewart MacArthur][1]
and [Dieter][2], the implementation idea is from [Bart Schaefer][3]. The
implementation is by [Jim Hester][5] in September 2012.
