* Description
This layer enables support for [[https://github.com/skuro/plantuml-mode][plantuml-mode]], which provides
a major-mode for [[http://plantuml.com][plantuml]]. PlantUML is a tool to generate [[https://en.wikipedia.org/wiki/Unified_Modeling_Language][UML diagrams]] from plain-text.
For help with how to use plantuml, see the [[http://plantuml.com][plantuml website]] and the [[http://plantuml.com/PlantUML_Language_Reference_Guide.pdf][reference guide]].
The official file extension supported by this layer is =.pum=. If you want something else,
set it in your =user-config= function of your =~/.spacemacs= file.
For example, the following diagram can be defined as follows:
#+BEGIN_SRC plantuml
@startuml
JAremko->robbyoconnor : I think the docs can benefit from some kind of illustration
JAremko<-robbyoconnor : I'm too lazy -- I have actual work to do. I link to the docs. If you can write me a diagram in plantuml, I'll gladly compile and add it.
JAremko->robbyoconnor : *gives ths diagram*
robbyoconnor<-JAremko : *robbyoconnor adds it and JAremko is happy*
...
robbyoconnor->theOtherPerson : And they thinks it's funny? Yup, they definitely finds it funny. Right?

** Features:
- Syntax highlighting
- Diagram preview in various output formats
- Embedding into org documents
- Controlling the =Plantuml= compiler directly from emacs
* Install
To use this contribution add it to your =~/.spacemacs=
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-configuration-layers '(plantuml))
#+END_SRC
To control the =Plantuml= compiler you also need to download the [[http://plantuml.com/download][Plantuml jar]]
and configure the =plantuml-jar-path= respectively:
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-configuration-layers '((plantuml :variables plantuml-jar-path "~/plantUml.jar")))
#+END_SRC
To get the full range of =Plantuml= compilations working, you will also need
the native package [[http://graphviz.org/][graphviz]] installed on your system.
* Org-Babel Integration
To enable the execution of embedded plantuml code blocks within [[http://orgmode.org/][Org-Mode]]
documents, define a value for =org-plantuml-jar-path= in your =~/.spacemacs=:
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-configuration-layers '((plantuml :variables org-plantuml-jar-path "~/plantUml.jar")))
#+END_SRC
