Features:
- Email searching
- Email tagging

* Emacs
** Better Defaults
[[file:+emacs/better-defaults/README.org][+emacs/better-defaults/README.org]]

This layer enhances the default commands of Emacs and is primarily intended to
be used with the =emacs= editing style as it does not change anything in the Vim
key bindings.

However the =emacs= editing style is not required. You can still use this layer
while you are using the =vim= editing style if you have some kind of mixed
style, but some of the layer bindings might be shadowed by the evil key bindings.

The commands defined in this layer are taken from various sources like [[https://github.com/bbatsov/prelude][Prelude]].

Features:
- Smart line navigation: Subsequent presses of ~C-a~ toggles between the beginning of the line and the first non-whitespace character. Similarly, subsequent presses of ~C-e~ will toggle between the end of the code and the end of the comments.
- =spacemacs/backward-kill-word-or-region=: A combination of =kill-region= and =backward-kill-word=, depending on whether there is an active region. If there's an active region kill that. If not kill the preceding word.
- Fill or unfill paragraph: Pressing ~M-q~ for the first time fills current paragraph and pressing ~M-q~ for the second time unfills it. Note that some modes override this key binding so it's not available everywhere. Due to implementation details unfilling doesn't work when called twice via ~M-x~.

** Helpful
[[file:+emacs/helpful/README.org][+emacs/helpful/README.org]]

This layer replaces the existing emacs related help buffers with more detailed ones.

Features:
- Better help buffers with [[https://github.com/Wilfred/helpful][helpful]] for emacs related buffers

- More detailed descriptions in the emacs specific function, variable and key help buffers
- Better formatted elisp docstrings

** IBuffer
[[file:+emacs/ibuffer/README.org][+emacs/ibuffer/README.org]]

This layer configures Emacs IBuffer for Spacemacs.

Features:
- Grouping of buffers by major-modes
- Grouping of buffers by projects

** Org
[[file:+emacs/org/README.org][+emacs/org/README.org]]

This layer enables [[http://orgmode.org/][org mode]] for Spacemacs.

Features:
- Vim inspired key bindings are provided by [[https://github.com/Somelauw/evil-org-mode][evil-org-mode]]
- Nicer bullet via [[https://github.com/integral-dw/org-superstar-mode][org-superstar-mode]]

- Pixel-perfect visual alignment for Org and Markdown tables via [[https://github.com/casouri/valign][valign]]

** Outshine
[[file:+emacs/outshine/README.org][+emacs/outshine/README.org]]

This layer adds support for [[https://github.com/alphapapa/outshine][outshine]] and [[https://github.com/alphapapa/outorg][outorg]]. They will be enabled in all
programming modes.

Features:
- Navigate through code buffers via headings like you do with org buffers
- Edit comments under outline headings in separate org-mode buffers

** Quickurl
[[file:+tools/quickurl/README.org][+tools/quickurl/README.org]]

Quickurl is a package in vanilla emacs for saving and inserting URLs. These
are key bindings for the various methods of insertion, which are not bound by
default.

Features:
- Key bindings to dispatch Quickurl (which is in vanilla Emacs).

** Semantic
[[file:+emacs/semantic/README.org][+emacs/semantic/README.org]]

CEDET is a *C*ollection of *E*macs *D*evelopment *E*nvironment *T*ools written
with the end goal of creating an advanced development environment in Emacs.
CEDET includes common features such as intelligent completion, source code
navigation, project management, code generation with templates. CEDET also
provides a framework for working with programming languages; support for new
programming languages can be added and use CEDET to provide IDE-like features.
This framework is called Semantic.

Semantic is a package that provides a framework for writing parsers. Parsing is
a process of analyzing source code based on programming language syntax. The
packages relies on Semantic for analyzing source code and uses its results to
perform smart code refactoring that based on code structure of the analyzed
language, instead of plain text structure. Semantic is the core of CEDET.

Features:
- Display function or variable definition at the bottom.
- Display current function cursor is in at the top. See
  [[https://github.com/tuhdo/semantic-stickyfunc-enhance][this page]] for demos in some programming languages.
- Support common C/C++ refactoring with [[https://github.com/tuhdo/semantic-refactor][semantic-refactor]]. See
  [[https://github.com/tuhdo/semantic-refactor/blob/master/srefactor-demos/demos.org][this page]] for demonstration of refactoring features.
- Support Lisp source code formatting with [[https://github.com/tuhdo/semantic-refactor][semantic-refactor]]. See
  [[https://github.com/tuhdo/semantic-refactor/blob/master/srefactor-demos/demos-elisp.org][this page]] for demonstration of Lisp formatting features.

** Smex
[[file:+emacs/smex/README.org][+emacs/smex/README.org]]

This layer provides a more traditional alternative to =helm-M-x= based on =ido=.

Features:
- Provides an alternative way for =helm-M-x= based on =ido= and [[https://github.com/nonsequitur/smex][smex]]

** Tabs
[[file:+emacs/tabs/README.org][+emacs/tabs/README.org]]

This layer adds support for tabs. Implementation is done using [[https://github.com/ema2159/centaur-tabs][Centaur Tabs]].

Features:
- Sets up tabs using Centaur tabs as backend
- Optionally auto hide tabs after delay

** Typography
[[file:+emacs/typography/README.org][+emacs/typography/README.org]]

This layer provides support for typographic text editing in Spacemacs.

Features:
- Modes to automatically insert and cycle among typographic characters
- [[https://github.com/jorgenschaefer/typoel][Typo Mode]] automatically inserts and cycles among typographic Unicode
  characters on some keys.
- Tildify Mode automatically inserts non-breaking spaces where
  required (Only available on Emacs 25).

* File trees
** Neotree
[[file:+filetree/neotree/README.org][+filetree/neotree/README.org]]

This layer setups a file tree navigator buffer using Neotree (replacing the Treemacs layer).

** Treemacs
[[file:+filetree/treemacs/README.org][+filetree/treemacs/README.org]]

This layer sets up a file navigation and project explorer side-window via [[https://github.com/Alexander-Miller/treemacs][Treemacs]].

Features:

A detailed overview of the features of Treemacs is available in [[https://github.com/Alexander-Miller/treemacs#detailed-feature-list][the Treemacs
readme]]. In short, Treemacs offers:
- Simple and powerful navigation and ability to detail exactly how and where a
  file should be opened.
- Good looking icons.
- Display of multiple file trees organized as projects residing in a workspace.
- Ability to show tags contained in files. Tags are provided by [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Imenu.html][Imenu]], so nearly
  every filetype is supported.
- Mouse interface for single and double left clicks in line with modern GUI
  standards (clicking on an icon will also display the file's tags).
- Location awareness: commands like ~find-file~ or ~magit-status~ will use the
  location of the node at point (with =$HOME= as fallback).
- Optional fontifying of files based on their git status.
- Optional collapsing of /single-dir-child/ directories into one.
- Doing both asynchronously for an imperceptible performance cost.
- Optional =follow-mode= to automatically focus the currently selected file or tag.

Anymore!
