From: Ingo Bürk Date: Tue, 24 Mar 2015 22:07:25 +0000 (+0100) Subject: Add support for a custom separator symbol X-Git-Tag: 4.10.1~23^2 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=80da100ac84890890594f8df951cc20a522d7922;p=i3%2Fi3 Add support for a custom separator symbol This introduces a "separator_symbol" property for the i3bar configuration. If set, the specified string will be used as a separator instead of a vertical line. Since it is an optional configuration, complete backwards compatibility is given. fixes #1472 --- diff --git a/docs/userguide b/docs/userguide index 45b05a06..d60eefb2 100644 --- a/docs/userguide +++ b/docs/userguide @@ -1249,6 +1249,24 @@ bar { } -------------------------------------------------------------- +=== Custom separator symbol + +Specifies a custom symbol to be used for the separator as opposed to the vertical, +one pixel thick separator.
