Tagging\015\012\015\012{{>toc}}\015\012\015\012\015\012Tags are generally used in subtle for placement of clients. This placement is mandatory, that means that - aside from other tiling window managers - clients must have a matching tag to be on a certain view. This also includes that clients, that are started on a certain view, aren't automatically placed there.\015\012\015\012There are two ways to define a tag in the config:\015\012\015\012h2. Simple\015\012\015\012The simple way just needs a name and a regular expression to just handle the placement:\015\012\015\012
tag "tag", "xterm"
\015\012\015\012h2. Extended\015\012\015\012Additionally tags can do a lot more then just control the placement - they also have properties to define and control some aspects of a client like the gravity or modes.\015\012\015\012
{{hide}}\015\012tag "tag" do\015\012  match   "xterm|[u]?rxvt"\015\012  gravity :center\015\012end\015\012
\015\012\015\012h2. Default\015\012\015\012Whenever a client has no tags it gets the default tag and is placed on the default view.\015\012\015\012Example:\015\012\015\012
{{hide}}\015\012view "terms", "terms",\015\012view  "www", "default|browser",\015\012view  "dev", "editor"\015\012
\015\012\015\012h2. Properties\015\012\015\012Following properties exist:\015\012\015\012{{needs(r2900)}}\015\012\015\012h3. Borderless \015\012\015\012This property enables the borderless mode for tagged clients.\015\012\015\012
{{hide}}\015\012tag "borderless" do\015\012  match       "xterm"\015\012  borderless  true\015\012end
\015\012\015\012{{needs(r2909)}}\015\012\015\012h3. Center\015\012\015\012This property enables the center mode for tagged clients.\015\012\015\012
{{hide}}\015\012tag "center" do\015\012  match   "xterm"\015\012  center  true\015\012end
\015\012\015\012{{needs(r2890)}}\015\012\015\012h3. Fixed\015\012\015\012This property enables the fixed mode for tagged clients.\015\012\015\012
{{hide}}\015\012tag "fixed" do\015\012  match "xterm"\015\012  fixed  true\015\012end
\015\012\015\012h3. Float\015\012\015\012This property enables the floating mode tagged clients.\015\012\015\012
{{hide}}\015\012tag "float" do\015\012  match"xterm"\015\012  float true\015\012end\015\012
\015\012\015\012h3. Full\015\012\015\012This property enables the fullscreen mode for tagged clients.\015\012\015\012
{{hide}}\015\012tag "full" do\015\012  match "xterm"\015\012  full  true\015\012end\015\012
\015\012\015\012h3. Geometry\015\012\015\012This property sets a certain geometry as well as floating to the tagged client, but only on views that have this tag too. It expects an array with x, y, width and height values whereas width and height must be >0.\015\012\015\012
{{hide}}\015\012tag "geometry" do\015\012  match    "xterm"\015\012  geometry [ 10, 10, 100, 100 ]\015\012end\015\012
\015\012\015\012h3. Gravity\015\012\015\012This property sets a certain to gravity to the tagged client, but only on matching views.\015\012\015\012
{{hide}}\015\012tag "gravity" do\015\012  match   "xterm"\015\012  gravity :center\015\012end\015\012
\015\012\015\012h3. Match\015\012\015\012This property adds a matcher to a tag, that is either a simple regular expression (see regex) or a selector based on different values/properties of a client.\015\012\015\012h4. Regular expression\015\012\015\012When a regular expression is used, subtle uses both parts of the WM_CLASS property for matching.\015\012\015\012h4. Selector\015\012\015\012A selector is a more complicated, but finer grained way to match clients and it even allows to combine multiple matcher with simple boolean logic.\015\012\015\012Every selector consists of a type and a value:\015\012\015\012
{{hide}}\015\012tag "example" do\015\012  match type: value\015\012end\015\012
\015\012\015\012Following types exist:\015\012\015\012| :name | Match the window name |\015\012| :instance | Match the window instance name |\015\012| :class | Match the window class name |\015\012| :role | Match the window role |\015\012| :type | Match the window type |\015\012\015\012{{needs(r2830)}}\015\012\015\012h4. Boolean logic\015\012\015\012Boolean logic allows to select a broader range of clients without difficult regular expressions and/or a required combination of multiple selector types.\015\012\015\012h5. AND\015\012\015\012All selector are required in order for this tag to be applied.\015\012\015\012
{{hide}}\015\012tag "AND" do\015\012  match instance: "xterm", instance: "urxvt"\015\012end\015\012
\015\012\015\012h5. OR\015\012\015\012Only one matching selector is required in order for this tag to be applied.\015\012\015\012
{{hide}}\015\012tag "OR" do\015\012  match "xterm"\015\012  match "urxvt"\015\012end\015\012
\015\012\015\012{{info(When dealing with console-based apps please keep in mind, that tagging via WM_NAME won't work as expected. Tags are usually applied when the terminal starts and before the shell with the app is spawned.)}}\015\012\015\012Please also check the How do I tag console based programs? FAQ entry.\015\012\015\012{{needs(r3209)}}\015\012\015\012h3. On_match\015\012\015\012This property adds Ruby proc to a tag that is called whenever the tag is applied to a client. This allows to add logic to a tag to ease e.g. simple placement tags.\015\012\015\012
{{hide}}\015\012tag "gimp" do\015\012  match role: "gimp.*"\015\012\015\012  on_match do |c|\015\012    c.gravity = ("gimp_" + c.role.split("-")[1]).to_sym\015\012  end\015\012end\015\012
\015\012\015\012h3. Position\015\012\015\012Similar to the geometry property, this property just sets the x/y coordinates of the tagged client, but only on views that have this tag, too. It expects an array with x and y values.\015\012\015\012
{{hide}}\015\012tag "position" do\015\012  match    "xterm"\015\012  position [ 10, 10 ]\015\012end\015\012
\015\012\015\012h3. Resize\015\012\015\012This property enables the resize mode for tagged clients. When set, subtle honors size hints of the clients, that define various size constraints like sizes for columns or rows of a terminal.\015\012\015\012
{{hide}}\015\012tag "resize" do\015\012  match  "xterm"\015\012  resize true\015\012end\015\012
\015\012\015\012h3. Stick\015\012\015\012This property enables the sticky mode for tagged clients. When set, clients are visible on all view, even when they don't have matching tags. On multihead sticky clients stay on the current screen as long as they are [Clients#Sticky|sticky]].\015\012\015\012{{needs(r3164)}}\015\012Supported values are either true or a number to specify a screen.\015\012\015\012
{{hide}}\015\012tag "stick" do\015\012  match "xterm"\015\012  stick true\015\012end\015\012
\015\012\015\012h3. Type\015\012\015\012This property sets the tagged client to be treated as a specific window type though as the window sets the type itself. \015\012\015\012Following types are possible:\015\012\015\012{{needs(r2905)}}\015\012\015\012| :normal | Treat as normal window |\015\012| :desktop | Treat as desktop window (_NET_WM_WINDOW_TYPE_DESKTOP) |\015\012| :dock | Treat as dock window (_NET_WM_WINDOW_TYPE_DOCK) |\015\012| :toolbar | Treat as toolbar windows (_NET_WM_WINDOW_TYPE_TOOLBAR) |\015\012| :splash | Treat as splash window (_NET_WM_WINDOW_TYPE_SPLASH) |\015\012| :dialog | Treat as dialog window (_NET_WM_WINDOW_TYPE_DIALOG) |\015\012\015\012
{{hide}}\015\012tag "desktop" do\015\012  match   "xterm"\015\012  type    :desktop\015\012end\015\012
\015\012\015\012h3. Urgent\015\012\015\012This property enables the urgent mode for tagged clients. When set, subtle automatically sets this client to [Clients#Urgent|urgent]].\015\012\015\012
{{hide}}\015\012tag "urgent" do\015\012  match  "xterm"\015\012  urgent true\015\012end\015\012
\015\012\015\012{{needs(r2871)}}\015\012\015\012h3. Zaphod\015\012\015\012This property enables the zaphod mode for tagged clients. When set, the client spans across all connected screens.\015\012\015\012
{{hide}}\015\012tag "zaphod" do\015\012  match  "xterm"\015\012  zaphod true\015\012end
\015\012\015\012h2. Examples\015\012\015\012
{{hide}}\015\012tag "bashrun" do\015\012  match    "bashrun"\015\012  geometry [ 50, 1000, 200, 28 ]#\015\012  stick    true\015\012  urgent   true\015\012end\015\012\015\012tag "browser" do\015\012  match   "chrom[e|ium]"\015\012  gravity :center\015\012end\015\012
