+# Xcode
+
+## Description
+
+This plugin provides a few utilities that can help you on your daily use of Xcode and iOS development.
+
+To start using it, add the `xcode` plugin to your `plugins` array in `~/.zshrc`:
+
+```zsh
+plugins=(... xcode)
+```
+
+
+## Aliases
+
+| Alias | Description                              | Command                                        |
+|-------|------------------------------------------|------------------------------------------------|
+| xcb   | Build Xcode projects and workspaces      | xcodebuild                                     |
+| xcdd  | Purge all temporary build information    | rm -rf ~/Library/Developer/Xcode/DerivedData/* |
+| xcp   | Show currently selected Xcode directory  | xcode-select --print-path                      |
+| xcsel | Select different Xcode directory by path | sudo xcode-select --switch                     |
+
+
+
+## Functions
+
+###  `xc`
+
+Opens the current directory in Xcode as an Xcode project. This will open one of the `.xcworkspace` and `.xcodeproj` files that it can find in the current working directory.
+Returns 1 if it didn't find any relevant files.
+
+###  `simulator`
+
+Opens the iOS Simulator from your command line, dependent on whichever is the active developer directory for Xcode. (That is, it respects the `xcsel` setting.)
+
+### `xcselv`
+
+Selects different Xcode installations by version name. This is like `xcsel`, except it takes just a version name as an argument instead of the full path to the Xcode installation. Uses the naming conventions described below.
+
+* `xcselv <version>` selects a version
+ * Example: `xcselv 6.2`
+* `xcselv default` selects the default unversioned `Applications/Xcode.app`
+* `xcselv` with no argument lists the available Xcode versions in a human-readable format
+* `xcselv -l` lists the installed Xcode versions
+* `xcselv -L` lists the installed Xcode versions in a short version-name-only format
+* `xcselv -p` prints info about the active Xcode version
+* `xcselv -h` prints a help message
+
+The option parsing for `xcselv` is naive. Options may not be combined, and only the first option is recognized.
+
+## Multiple Xcode Versions
+
+The `xcselv` command provides support for switching between different Xcode installations using just a version number. Different Xcode versions are identified by file naming conventions.
+
+### Versioned Xcode Naming Conventions
+
+Apple does not seem to explicitly define or provide tooling support for a naming convention or other organizational mechanism for managing versioned Xcode installations. Apple seems to have released beta versions with both `Xcode<version>.app` and `Xcode-<version>.app` style names in the past, and both styles show up in forum and blog discussions.
+
+We've adopted the following naming convention:
+
+* Versioned Xcode installations are identified by the name `Xcode-<version>` or `Xcode<version>`.
+* The `-` separating `"Xcode"` and the version name is optional, and may be replaced by a space.
+* The versioned name may be applied to the `Xcode.app` itself, or a subdirectory underneath `Applications/` containing it.
+* You cannot version both the `Xcode.app` filename itself and the containing subfolder.
+* Thus, all of the following are equivalent.
+ * `Applications/Xcode-<version>.app`
+ * `Applications/Xcode-<version>/Xcode.app`
+ * `Applications/Xcode<version>.app`
+ * `Applications/Xcode <version>.app`
+ * `Applications/Xcode <version>/Xcode.app`
+* Both the system `/Applications/` and user `$HOME/Applications/` directories are searched.
+ * The user's `$HOME/Applications/` takes precedence over `/Applications` for a given version.
+ * If multiple naming variants within the same `Applications/` folder indicate the same version (for example, `Xcode-3.2.1.app`, `Xcode3.2.1.app`, and `Xcode-3.2.1/Xcode.app`), the precedence order is unspecified and implementation-dependent.
+* The `<version>` may be any string that is valid in a filename.
+* The special version name `"default"` refers to the "default" unversioned Xcode at `Applications/Xcode.app` (in either `/Applications/` or `$HOME/Applications/`).
+* Version names may not start with ``"-"`` or whitespace.
+
+The restrictions on the naming convention may need to be tightened in the future. In particular, if there are other well-known applications whose names begin with the string `"Xcode"`, the strings allowed for `<version>` may need to be restricted to avoid colliding with other applications. If there's evidence that one of these naming techniques is strongly favored either in practice or by Apple, we may tighten the naming convention to favor it.
+
+## Caveats
+
+Using `xcsel` or `xcselv` to select an Xcode that is installed under your `$HOME` may break things for other users, depending on your system setup. We let you do this anyway because some people run OS X as effectively single-user, or have open permissions so this will work. You could also use `$DEVELOPER_DIR` as an alternative to `xcsel` that is scoped to the current user or session, instead of a global setting.
+
+This does not verify that the version name in the Xcode filename matches the actual version of that binary. It is the user's responsibility to get the names right.

+#          FILE: emotty.zsh-theme
+#   DESCRIPTION: A varying emoji based theme
+#        AUTHOR: Alexis Hildebrandt (afh[at]surryhill.net)
+#       VERSION: 1.0.0
+#       DEPENDS: emotty plugin
+#    RECOMMENDS: Hasklig font
+#
+# This theme shows a different emoji for each tty at the main prompt.
+#
+# There are pre-defined different emoji sets to choose from, e.g.:
+# emoji, stellar, floral, zodiac, love (see emotty plugin).
+# 
+# To choose a different emotty set than the default (emoji)
+# % export emotty_set=nature
+#
+# For the superuser (root) this theme shows a designated indicator
+# and switches the foreground color to red
+# (see root_prompt variable, default: skull).
+# But you are using sudo (8) instead of designated a root shell, right‽
+#
+# When logged in via SSH the main prompt also shows the user- and hostname.
+#
+# The exit status of the last failed command is displayed in the window title
+# along with an indicator (see warn_glyph variable, default: collision symbol).
+# To clear it just run: $NULL, true or :
+#
+# The right prompt shows the current working directory (3 levels up) in cyan.
+#
+# When in a git repository the main prompt shows the current branch name
+# with a branch indicator in yellow
+# (see vcs_branch_glyph variable, default: Hasklig branch glyph).
+#
+# If there are modified files the prompt switches to red and shows an unstaged
+# indicator (see vcs_unstaged_glyph variable, default: circled letter M).
+#
+# If there are staged files the prompt switches to green and shows an staged
+# indicator (see vcs_staged_glyph variable, default: high voltage sign).
+#
+# In a git repository the right prompt shows the repository name in bold and
+# prepends the current working directory subpath within the repository.
+#
+# When git currently performs an action such as merge or rebase, the action is
+# displayed in red instead of the branch name and a special action indicator
+# is shown (see vcs_action_glyph variable, default: chevron).
