* Description
  This layer adds features for conlanging.

** Features
   - Generate graphviz trees based on Elisp trees
   - Replace  some  text  by  its  runic equivalent  (supports  the  Mattér  and
     Eittlandic languages)
   - Adds phonetics to Proto-Ñyqy text
   - Provides custom shortcuts

** Graphviz trees
   The    ~conlanging~   layer    provides    one    public   function    called
   ~conlanging/tree-to-dot~. It accepts as its sole argument a list of strings
   or lists, such as the following:

   #+NAME: vowels-example
   #+BEGIN_SRC emacs-lisp :noweb yes
     (setq-local vowels
       '("[vowel]"
         ("[back]"
          ("[tense]"
           ("[high]" ("ü"))
           ("{high}" ("ö")))
          ("{tense}"
           ("[high]" ("u"))
           ("{high}" ("o"))))
         ("{back}"
          ("[tense]"
           ("[high]" ("y"))
           ("{high}" ("ë")))
          ("{tense}"
           ("[high]" ("i"))
           ("{high}" ("e"))))))
   #+END_SRC

   When passed in the above mentioned  function, and the result itself is passed
   through graphviz, we get the following result:

   #+NAME: tree-vowels
   #+BEGIN_SRC emacs-lisp :exports results :noweb yes :cache yes
     <<vowels-example>>
     (conlanging/tree-to-dot vowels)
   #+END_SRC

   #+BEGIN_SRC dot :file img/vowels-example.png :var input=tree-vowels :exports results
     $input
   #+END_SRC
   #+NAME: arbre:vow
   #+ATTR_HTML: :alt Exemple d’arbre de voyelles
   #+RESULTS:
   [[file:img/vowels-example.png]]

   This example tree is only a binary tree, but a single node can have up to ten
   children. See some examples in the [[https://labs.phundrak.com/phundrak/langue-phundrak-fr/blob/master/proto-nyqy.org][Ñyqy source file]].

   It is planned  to merge [[https://labs.phundrak.com/phundrak/distinctive-features-chooser][this project]]  into this layer in  order to facilitate
   the creation of trees based on distinctive features.

* Install
  To install this layer, either clone this project in your =~/.emacs.d/private/=
  folder, or  symlink it  from there  to your actual  clone location.  Then, add
  =conlanging=       in      your       dotspacemacs      file       in      the
  =dotspacemacs-configuration-layers= list:

  #+begin_src emacs-lisp
    (setq-default dotspacemacs-configuration-layers '(conlanging))
  #+end_src

  You can then reload your configuration file with ~SPC f e R~, or restart Emacs
  with ~SPC q r~ or ~SPC q R~.
