# 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"
      ]

    myTopicConfig :: TopicConfig
    myTopicConfig = def

type Topic = WorkspaceId Source #

`Topic` is just an alias for `WorkspaceId`

type Dir = FilePath Source #

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

data TopicConfig Source #

Here is the topic space configuration area.

Constructors

Fields

- topicDirs :: Map Topic Dir

  This 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 :: Topic

  This is the default topic.

- maxTopicHistory :: Int

  This setups the maximum depth of topic history, usually 10 is a good default since we can bind all of them using numeric keypad.

setLastFocusedTopic :: Topic -> (Topic -> Bool) -> X () Source #
