A Node.Js module for converting [PlantUML](http://plantuml.com) files to graphics formats: SVG, PNG, EPS.
1. [Graphviz](http://www.graphviz.org/) installed.
2. Path to Grapviz Dot executable directory registered in system PATH.
```bash
npm i esf-puml
```
Ensure `tst/d/out` is writable, or redefine it in `tst/index.js`.` Then run:
```bash
esf-puml> npm i -D
esf-puml> gulp test
```
The module includes the MIT licensed version, available from [MIT licensed PlantUML download](http://plantuml.com/download.html#mit).

## Requirements
### esf-puml-1
ReqId | Requirement | Implementation Methods
------------ | ------------------------------------------------------------------------------------------------------- | ----------------------
esf-puml-1 | There should be an option to chose a result format: <ul><li>`png`</li><li>`svg`</li><li>`eps`</li></ul> |
esf-puml-2 | Rendering PUML-files from a directory recursively | `renderDir`
esf-puml-2.1 | It should gather puml-files from nested directories recursively and create the same temporary structure |
esf-puml-2.2 | It should render all the files |
esf-puml-2.3 | It should delete puml-sources |
esf-puml-2.4 | It should move the result to the `out` directory |
esf-puml-3 | Rendering a string input | `renderString`
esf-puml-3.1 | It should accept puml-string as input |
esf-puml-3.2 | It should save an output file at a specified path |
esf-puml-4 | Rendering a single file | `renderFile`
esf-puml-4.1 | It should gather puml-files from nested directories recursively at `inp` as a root |
esf-puml-4.2 | It should write the result in chosen format to Writable stream |
esf-puml-5 | Process a stream | `stream`
esf-puml-5.1 | It should read a stream |
esf-puml-5.2 | It should return a Readable stream |
esf-puml-6 | It should implement API v.1.0 |
esf-puml-7 | Rendering a string input to string output | `renderStringToString`
esf-puml-7.1 | It should accept puml-string as input |
esf-puml-7.2 | It should return an svg image |
esf-puml-8 | It should automatically detect source and provide an according method, API 1.1 imlementation | `render`
## API
### v.1.1
```javascript
Promise render ([string inpDir|inpFile], string outDir=null [,format='svg']) //
Promise renderDir (string inpDir, string outDir, [,format='svg']) //
Promise renderFile (string inpFilePath, string outDir [,format='svg']) //
Promise renderString (string pumlString, string outFilePath [,format='svg']) //
Promise renderStringToString (string pumlString, [,string format='svg']) //
stream.Duplex stream ([format='svg'] [,string cwd=null]) // custom Cwd
```
### v.1.0
```javascript
Promise renderDir (string inpDir, string outDir, [,format='svg']) //
Promise renderFile (string inpFilePath, string outDir [,format='svg']) //
Promise renderString (string pumlString, string outFilePath [,format='svg']) //
Promise renderStringToString (string pumlString, [,format='svg']) //
stream.Duplex stream ([,format='svg'] [,cwd=null]) // custom Cwd
```
