This module provides a grunt multi-task generating images from [plantuml]
diagram sources.
If you generate HTML technical documention from textual sources, you may want
to maintain only sources of UML diagrams in your repository and generate the
pictures only during the documentation build. You will be able to do changes
easily, without committing both diagram sources and pictures and sychronizing
them manually.
If you want to just quickly convert a plantuml source file to a picture, you
can use the [node-plantuml] command-line tool `puml`, which this task is based
on.
## Installation
You need [node >= 0.12][node], [npm] and [grunt >= 0.4][Grunt] installed
and your project build managed by a [Gruntfile] with the necessary modules
listed in [package.json]. If you haven't used Grunt before, be sure to
check out the [Getting Started] guide, as it explains how to create a
Gruntfile as well as install and use Grunt plugins. Once you're familiar
with that process, you may ensure native dependencies of this plugin and
install it:
1. Install pre-requisites: [Graphviz](http://www.graphviz.org/) and Java
depending on your operating system
2. Install the Grunt task:
```shell
$ npm install grunt-plantuml --save-dev
```
## Configuration
Add the `plantuml` entry with the plantuml task configuration to the
options of the `grunt.initConfig` method:
```js
grunt.initConfig({
plantuml: {
one: {
files: {
'dist/doc/images/diagram.png': ['doc/images/diagram.puml']
}
},
all: {
src: ['doc/images/*.puml']
dest: 'dist/doc/images'
}
}
});
```
The configuration consists of key-value pairs with the output image path
as a key pointing to the plantuml input file. If you specify more source
files by wildcards, the destination should be a directory; the source file
extension wil lbe replaced by the output format in the output file name.
Then, load the plugin:
```javascript
grunt.loadNpmTasks('grunt-plantuml');
```
## Build
Call the `plantuml` task:
```shell
$ grunt plantuml
```
or integrate it to your build sequence in `Gruntfile.js`:
```js
grunt.registerTask('default', ['plantuml', ...]);
```
## Customizing
Default behaviour of the task can be tweaked by the task options; these
are the defaults:
```js
grunt.initConfig({
plantuml: {
one: {
files: {
'dist/doc/images/diagram.png': ['doc/images/diagram.puml']
},
options: {
dot: '...', // path to the dot executable
config: '...', // path to the dot config file
charset: 'utf-8', // source file character set
format: 'png' // ascii|unicode|eps|png|svg
}
}
}
});
```
