-- statusbar_workspace.lua
--
-- Show current workspace name or number in the statusbar.
--
-- Put any of these in cfg_statusbar.lua's template-line:
--  %workspace_name
--  %workspace_frame
--  %workspace_pager
--  %workspace_name_pager
--  %workspace_num_name_pager
--
-- This is an internal statusbar monitor and does NOT require
-- a dopath statement (effective after a 2006-02-12 build).

-- version 1
-- author: Rico Schiekel <fire at paranetic dot de>
--
-- version 2
-- added 2006-02-14 by Canaan Hadley-Voth:
--  * %workspace_pager shows a list of workspace numbers
--    with the current one indicated:
--
--    1i  2i  [3f]  4p  5c
--
--    i=WIonWS, f=WFloatWS, p=WPaneWS, c=WClientWin/other
--
--  * %workspace_frame - name of the active frame.
--
--  * Added statusbar_ to the filename (since it *is*
--    an internal statusbar monitor) so that it works without
--    a "dopath" call.
--
--  * Removed timer.  Only needs to run on hook.
--    Much faster this way.
--
-- version 3
-- update for ion-3rc-20070506 on 2007-05-09
-- by Kevin Granade <kevin dot granade at gmail dot com>
--
-- Updated to use new wx_ api
-- Replaced region_activated_hook with region_notify_hook
-- Added %workspace_name_pager, which works similarly to %workspace_pager,
--   but instead displays the name of each workspace
-- Added display for WGroupWS to %workspace_pager, displayed as 'g'
