# js-dot-antlr-parser

The objective of this project is to demostrate how to capture diagnostics i.e., semantic and syntactic errors for DOT language using ANTLR parser written in Javascript.

# Installation

```script

npm install --save js-dot-antlr-parser

```

# Usage

```javascript

const jdap = require('js-dot-antlr-parser');

console.log(JSON.stringify(jdap.doValidation("gaph { \n a -- b \n a - b \n b - a [color=blue] \n }")));

console.log(JSON.stringify(jdap.doValidation("gaph { \n a -- b \n a - b \n b - a [color=blue] \n }").semanticErrors));

console.log(JSON.stringify(jdap.doValidation("gaph { \n a -- b \n a - b \n b - a [color=blue] \n }").syntacticErrors));

```

# Output
