PlantUML mode for Emacs
=======================

**NOTE**: This is currently almost only a GitHub mirror of the nice job done by [Zhang
Weize](http://zhangweize.wordpress.com/2010/09/20/update-plantuml-mode/)
as I couldn't find anything like a source repository. Just minor changes were introduced.

Provides a [PlantUml](http://plantuml.sourceforge.net/) major mode for
Emacs.

Installation
============

Make sure you have [MELPA](http://melpa.org/) enabled in your ``emacs.d``. Then, you can just

    M-x package-install<RET>
    puml-mode<RET>

Enjoy!

Features
========

- Syntax highlight
- Autocompletion
- Preview

Enable the major mode
=====================

You can automatically enable `puml-mode` for files with extension `.puml` or `plantuml` by adding the following to your `.emacsrc`:

    ;; Enable puml-mode for PlantUML files
    (add-to-list 'auto-mode-alist
                 '("\\.puml\\'" . puml-mode)
                 '("\\.plantuml\\'" . puml-mode))

Of course, you can always enable manually the major mode by typing `M-x puml-mode` once in the desired PlantUML file buffer.

Usage
=====

You can either tell `puml-mode` to autocomplete the word before the cursor by typing `M-x puml-complete-symbol`. This will open a popup with all the available completions as found in the list of keywords given by running PlantUML with the `-language` flag.

To render the PlantUML diagram within Emacs, you can also hit `M-x puml-preview`. This will run PlantUML and display the result in the `*PUML-Preview*` buffer. The format used to render the diagram is automagically chosen from what's supported by your Emacs. It will be one of the following, in order of preference:

- SVG
- ~~PNG~~ still unsupported, see #6
- Unicode ASCII art

Default key bindings
====================

The following shortcuts are enabled by default:

    C-c C-c  renders a PlantUML diagram from the current buffer in the best supported format
