Small and silly parser based on the [Tree Sitter](https://tree-sitter.github.io/tree-sitter/)

JavaScript parser implementation

## What does it do

This parser will make an attempt to find a specified lib `require` statement and then will find lines in a code for every variable reference (or a particular one if specified) for the object assigned to the require statement.

For Example if you have file `test.js` in the same folder as the script:

```javascript

const path = require('path');

module.exports = {

    entry: './src/app.js',

    output: {

        path: path.resolve(__dirname, 'bin'),

        filename: 'app.bundle.js',

    },

    plugins: [

        new HtmlWebpackPlugin({

            filename: './index.html',

            template: path.resolve(configDirs.APP_DIR_TEMPLATES, './index.prod.html'),

            inject: true,

            publicPath: path.join(configDirs.PUBLIC_PATH, 'public'),

        }),

        new HtmlWebpackInjector(),

    ],

};

```

The following command will find `path` lib `resolve` calls

```

./bin/silly-parser -f ./test.js -l path -p resolve

```

Should produce an output:

```

[]AllOccurrences of path referencing resolve:

   {

    const f = await fs1.readFile('/tmp/somefile.txt');

    res.send(f.toString('utf-8'));

});

```

Calling `./bin/silly-parser -f ../examples/example1.js -l fs/promises -p readFile` would yield no results because of the `const fs1 = fs;` line

Also more tests are required

Also it is not published to NPM. This CLI command cannot be installed using `npm install -g`
