Launch a few terminals so that we have something to work with:

colors = %w[ red green blue black orange brown gray navy gold ]
colors.each {|c| system "xterm -bg #{c} -title #{c} -e read &" }

Arrange all clients in a grid:

curr_view.arrange_in_grid

Arrange all clients in a diamond shape:

curr_view.arrange_in_diamond

Arrange all clients like LarsWM does:

curr_view.arrange_as_larswm

Close the terminals we launched earlier:

terms = curr_view.clients.select {|c| colors.include? c.label.read }
terms.each {|c| c.ctl.write "kill" }

Launch a few terminals so that we have something to work with:

colors = %w[ red green blue black orange brown gray navy gold ]
colors.each {|c| system "xterm -bg #{c} -title #{c} -e read &" }

Add the red, green, and blue terminals into the “grouping”:

terms = curr_view.clients.select {|c| %w[red green blue].include? c.label.read }
terms.each {|c| c.group }

You should now see a new button labelled as “@” on the left-hand side of wmii’s bar, indicating that there is now a new view labelled “@” in wmii. Let us inspect what clients this mysterious view contains:

v = View.new "@"
puts v.clients.map {|c| c.label.read }

Aha! The mysterious view contains the red, green, and blue clients we recently “grouped”. Thus, by adding a client to the “grouping”, we are simply tagging the client with the ”@” token.

Now that we have put some clients into the “grouping”, let us move all clients in the grouping to the floating area in the current view:

grouping.each {|c| c.send "toggle" }

Neat! Let us bring them back into the managed area:

grouping.each {|c| c.send "toggle" }

Close the terminals we launched earlier:

terms = curr_view.clients.select {|c| colors.include? c.label.read }
terms.each {|c| c.ctl.write "kill" }

In summary, you can select multiple clients (by adding them to the “grouping”) and perform operations on them. This is useful when you want to do something with a group of clients but do not want to manually focus one, perform the action, focus the next one, and so on.

Another important aspect is that selected clients stay selected until they are unselected. This allows you to continue performing tasks on the selection without having to reselect the same clients after every operation.

Launch a few terminals so that we have something to work with:

colors = %w[ red green blue black orange brown gray navy gold ]
colors.each {|c| system "xterm -bg #{c} -title #{c} -e read &" }

You can insert a group of clients to the top, bottom, or after the currently focused client of any column using Array-like methods.

Give each client its own column (one client per column):

curr_view.each_column {|c| c.length = 1 }

Put (at most) three clients in every column:

curr_view.each_column {|c| c.length = 3 }

Move the red, green, and blue clients into the floating area:

terms = curr_view.clients.select {|c| %w[red green blue].include? c.label.read }
curr_view.areas[0].push terms

Slurp all floating clients into the last column:

list = curr_view.areas
a, b = list.first, list.last
b.concat a

Set the last column’s layout to stacking mode:

b.layout = 'stack'

Move the red, green, and blue clients to the top of the second column:

curr_view.areas[2].unshift terms

Move the red, green, and blue clients to the bottom of the third column:

curr_view.areas[3].push terms

Close the terminals we launched earlier:

terms = curr_view.clients.select {|c| colors.include? c.label.read }
terms.each {|c| c.ctl.write "kill" }

Launch a few terminals so that we have something to work with:

colors = %w[ red green blue black orange brown gray navy gold ]
colors.each {|c| system "xterm -bg #{c} -title #{c} -e read &" }

Obtain a reference to the red client:

red = curr_view.clients.find {|c| c.label.read == "red" }

Show the red client’s current tags:

red.tags

Add the “foo” and “bar” tags to the red client:

red.tag "foo", "bar"

Remove the “bar” tag from the red client:

red.untag "bar"

Do complex operations on the red client’s tags:

red.with_tags { concat %w[a b c]; push 'z'; delete 'c' }

Focus the next client after the red client:

red.next.focus ; curr_client == red.next #=> true

Notice that by focusing a client, we make it the current client.

Focus the red client on a different view:

orig = curr_view
v = red.views.last
red.focus v

Return to the original view:

orig.focus

Send the red client to the last column:

red.send curr_view.areas.last

Close the terminals we launched earlier:

terms = curr_view.clients.select {|c| colors.include? c.label.read }
terms.each {|c| c.ctl.write "kill" }

Show the root node of wmii’s IXP file system:

fs

Show the names of all files at the root level:

fs.entries

Show the parent of the root node:

fs.parent

Show the children of the root node:

fs.children

Navigate into to the /lbar/ directory:

n1 = fs.lbar
n2 = fs['lbar']
n1 == n2 #=> true
left_bar = n1

Notice that you can traverse the file system hierarchy by simply calling methods on node objects. Alternatively, you can traverse by specifying an arbitrary sub-path (relative path) using the [] operator on a node.

Create a new temporary button:

b = left_bar.rumai_example # path of new button
b.exist? #=> false
b.create
b.exist? #=> true

You should now see an empty button on the left-hand side of the wmii bar.

Color the button black-on-white and label it as “hello world”:

content = "#000000 #ffffff #000000 hello world"
b.write content
b.read == content #=> true

Remove the temporary button:

b.remove
b.exist? #=> false
