Unexpected reserved word

[davidjbradshaw]

I get the following error when it sees the word 'import' in my code.

Error: Line 5: Unexpected reserved word

I am also getting this error despite using the following eslintrc:

{
  "extends": "airbnb/base",
  "rules": {
    "comma-dangle": 0
  },
  "env": {
    "browser": true,
    "jasmine": true,
    "node": true
  },
  "globals": {
    "_": false
  }
}

I'm using the following config:

const paths: {
  plato: {
      output: './build/reports/complexity',
      options: {
        eslint: '.eslintrc',
        title: 'JavaScript Complexity Report',
        recurse: true
      }
    }
};

And executing in this way:

plato.inspect([
    'app.js',
    'gulpfile.babel.js',
    'src/app.js',
    'src/main.js',
    'src',
    'build'
  ], 
  paths.reports.plato.output, 
  paths.reports.plato.options,
  report => console.log(report)
);

I don't get the errors when I use exec but the reports are empty:

exec(spawnSync('node_modules/plato/bin/plato', [
    '--dir',
    paths.reports.plato.output,
    '--recurse',
    '--title',
    'Plato Complexity Report',
    '--eslint',
    './.eslintrc',
    paths.root,
    'gulpfile.babel.js'
  ]));

When I run from the command line I also get the Unexpected reserved word error at import:

plato --dir 'build/reports/complexity' --recurse --title 'JavaScript Complexity Report' --eslint './.eslintrc' 'src'

[vtovikram]

This is because Plato is not able to figure out ES6
try this out with a transpiler like (https://babeljs.io/repl/).
This should fix the problem and i think there is a es6 fork also from plato.

[aaronroberson]

@vtovikram Can you provide some steps on how to use Babel with plato? Are you suggesting that I run plato against my transpiled files or can I run it against my source code but somehow piped through Babel?

[vtovikram]

yeah i did run it against my transpiled files it Worked, but ended up not using it. but again debugging on that was much harder to get my numbers better so gave up on it.
