---[[--
-This is the global rules table.
-
-You should fill this table with your rule and properties to apply.
-For example, if you want to set xterm maximized at startup, you can add:
-
- { rule = { class = "xterm" },
- properties = { maximized_vertical = true, maximized_horizontal = true } }
-
-If you want to set mplayer floating at startup, you can add:
-
- { rule = { name = "MPlayer" },
- properties = { floating = true } }
-
-If you want to put Firefox on a specific tag at startup, you can add:
-
- { rule = { instance = "firefox" },
- properties = { tag = mytagobject } }
-
-Alternatively, you can specify the tag by name:
-
- { rule = { instance = "firefox" },
- properties = { tag = "3" } }
-
-If you want to put Thunderbird on a specific screen at startup, use:
-
- { rule = { instance = "Thunderbird" },
- properties = { screen = 1 } }
-
-Assuming that your X11 server supports the RandR extension, you can also specify
-the screen by name:
-
- { rule = { instance = "Thunderbird" },
- properties = { screen = "VGA1" } }
-
-If you want to put Emacs on a specific tag at startup, and immediately switch
-to that tag you can add:
-
- { rule = { class = "Emacs" },
- properties = { tag = mytagobject, switchtotag = true } }
-
-If you want to apply a custom callback to execute when a rule matched,
-for example to pause playing music from mpd when you start dosbox, you
-can add:
-
- { rule = { class = "dosbox" },
- callback = function(c)
- awful.spawn('mpc pause')
- end }
-
-Note that all "rule" entries need to match. If any of the entry does not
-match, the rule won't be applied.
-
-If a client matches multiple rules, they are applied in the order they are
-put in this global rules table. If the value of a rule is a string, then the
-match function is used to determine if the client matches the rule.
-
-If the value of a property is a function, that function gets called and
-function's return value is used for the property.
-
-To match multiple clients to a rule one need to use slightly different
-syntax:
-
- { rule_any = { class = { "MPlayer", "Nitrogen" }, instance = { "xterm" } },
- properties = { floating = true } }
-
-To match multiple clients with an exception one can couple `rules.except` or
-`rules.except_any` with the rules:
-
- { rule = { class = "Firefox" },
- except = { instance = "Navigator" },
- properties = {floating = true},
- },
-
- { rule_any = { class = { "Pidgin", "Xchat" } },
- except_any = { role = { "conversation" } },
- properties = { tag = "1" }
- }
-
- { rule = {},
- except_any = { class = { "Firefox", "Vim" } },
- properties = { floating = true }
- }
