From: Tony Crisci Date: Mon, 5 May 2014 17:56:47 +0000 (-0400) Subject: i3bar: implement custom workspace numbers config X-Git-Tag: 4.8~41 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=e707e0a5fabf20351d727aecedd7c75db08c850c;p=i3%2Fi3 i3bar: implement custom workspace numbers config Implement the configuration option within the bar config directive for custom workspace numbers with the directive `strip_workspace_numbers yes`. This directive strips the workspace name of the number prefix and delimiter. When the workspace name consists only of the number, it will default to show the number. For example: * "2:5" -> "5" * "4:$" -> "$" * "8" -> "8" This allows customization of i3bar for alternate ordering of workspaces which has a legitimate use for alternate keyboard layouts such as Dvorak. fixes #1131 --- diff --git a/docs/userguide b/docs/userguide index 34f93815..6e5e5ff1 100644 --- a/docs/userguide +++ b/docs/userguide @@ -1191,6 +1191,31 @@ bar { } ------------------------ +=== Strip workspace numbers + +Specifies whether workspace numbers should be displayed within the workspace +buttons.
