|Subject: [PATCH] Allow bar order to be configured in config.h
|
|This patch adds char *barlayout to config(.def).h which can contain as
|many or as few of the characters 'l', 'n', 's', 't', or '|' to configure
|the order of dwm's bar.
|
|    l   Layout indicator;
|    n   Window name;
|    s   Status (set with xsetroot);
|    t   Tag indicators;
|    |   Split point.
|
|Everything before '|' (and if it is omitted) will appear on the left of
|the bar. Everything after will appear on the right, but in reverse
|order.
|
|By default, this patch leaves the bar as is.
