Overview
This module allows to organize your workspaces on a precise topic basis. So instead of having a workspace called work you can setup one workspace per task. Here we call these workspaces, topics. The great thing with topics is that one can attach a directory that makes sense to each particular topic. One can also attach an action which will be triggered when switching to a topic that does not have any windows in it. So you can attach your mail client to the mail topic, some terminals in the right directory to the xmonad topic... This package also provides a nice way to display your topics in an historical way using a custom pprWindowSet function. You can also easily switch to recent topics using this history of last focused topics.
Usage

Here is an example of configuration using TopicSpace:

 -- The list of all topics/workspaces of your xmonad configuration.
 -- The order is important, new topics must be inserted
 -- at the end of the list if you want hot-restarting
 -- to work.
 myTopics :: [Topic]
 myTopics =
   [ "dashboard" -- the first one
   , "admin", "build", "cleaning", "conf", "darcs", "haskell", "irc"
   , "mail", "movie", "music", "talk", "text", "tools", "web", "xmonad"
   , "yi", "documents", "twitter", "pdf"
   ]

Topic is just an alias for WorkspaceId

Dir is just an alias for FilePath but should points to a directory.

Here is the topic space configuration area.
Constructors
TopicConfig
topicDirs :: Map Topic DirThis mapping associate a directory to each topic.
topicActions :: Map Topic (X ())This mapping associate an action to trigger when switching to a given topic which workspace is empty.
defaultTopicAction :: Topic -> X ()This is the default topic action.
defaultTopic :: TopicThis is the default topic.
maxTopicHistory :: IntThis setups the maximum depth of topic history, usually 10 is a good default since we can bind all of them using numeric keypad.
getLastFocusedTopics :: X [String]Source
Returns the list of last focused workspaces the empty list otherwise. This function rely on a reserved property namely _XMONAD_LAST_FOCUSED_WORKSPACES.
setLastFocusedTopic :: TopicConfig -> Topic -> (Topic -> Bool) -> X ()Source
Given a TopicConfig, the last focused topic, and a predicate that will select topics that one want to keep, this function will set the property of last focused topics.
pprWindowSet :: TopicConfig -> PP -> X StringSource
This function is a variant of pprWindowSet which takes a topic configuration and a pretty-printing record PP. It will show the list of topics sorted historically and highlighting topics with urgent windows.
topicActionWithPrompt :: XPConfig -> TopicConfig -> X ()Source
Given a prompt configuration and a topic configuration, triggers the action associated with the topic given in prompt.
topicAction :: TopicConfig -> Topic -> X ()Source
Given a configuration and a topic, triggers the action associated with the given topic.
currentTopicAction :: TopicConfig -> X ()Source
Trigger the action associated with the current topic.
switchTopic :: TopicConfig -> Topic -> X ()Source
Switch to the given topic.
switchNthLastFocused :: TopicConfig -> Int -> X ()Source
Switch to the Nth last focused topic or failback to the defaultTopic.
shiftNthLastFocused :: Int -> X ()Source
Shift the focused window to the Nth last focused topic, or fallback to doing nothing.
currentTopicDir :: TopicConfig -> X StringSource
Returns the directory associated with current topic returns the empty string otherwise.
checkTopicConfig :: [Topic] -> TopicConfig -> IO ()Source
Check the given topic configuration for duplicates topics or undefined topics.
(>*>) :: Monad m => m a -> Int -> m ()Source
An alias for flip replicateM_
