Visualize JavaScript source complexity with plato.
Based on the older es5 plato, this is a port to es6 and eslint

The Report

!dank-es6-nugs

Start in 3 steps.

1. Install.
npm install --save-dev es6-plato

2. Add.

``
"scripts" : {
"complexity-report": "./node_modules/.bin/es6-plato -r -d ./report src",
}
`

3. Run.
npm run complexity-report

Installation

Install the module with: npm install --save-dev es6-plato

Usage

$3

`js
//be sure and set your src, output, and any options.
let src = "./scripts/*/.js";
let outputDir = "./artifacts/plato";

let platoArgs = {
title: "example",
eslint: {}
};

//you can use the reports in the callback.
function callback(reports) {
let overview = plato.getOverviewReport(reports);

let { total, average } = overview.summary;

let output = total
----------------------
eslint: ${total.eslint}
sloc: ${total.sloc}
maintainability: ${total.maintainability}
average
----------------------
eslint: ${average.eslint}
sloc: ${average.sloc}
maintainability: ${average.maintainability};

console.log(output);
}

//usage is plato.inspect
plato.inspect(src, outputDir, platoArgs, callback);
`

Example Gulpfile

`js
let gulp = require("gulp");
let plato = require("es6-plato");

let src = "./scripts/*/.js";
let outputDir = "./artifacts/plato";

let lintRules = {
rules: {
indent: [2, "tab"],
quotes: [2, "single"],
semi: [2, "always"],
"no-console": [1],
curly: ["error"],
"no-dupe-keys": 2,
"func-names": [1, "always"]
},
env: {
es6: true
},
globals: ["require"],
parserOptions: {
sourceType: "module",
ecmaFeatures: {
jsx: true,
modules: true
}
}
};

let complexityRules = {};

let platoArgs = {
title: "example",
eslint: lintRules,
complexity: complexityRules
};

function analysis() {
return plato.inspect(src, outputDir, platoArgs);
}

gulp.task("analysis", analysis);
`

$3

`sh
Usage : es6-plato [options] -d
-h, --help
Display this help text.
-q, --quiet
Reduce output to errors only
-v, --version
Print the version.
-x, --exclude : String
File exclusion regex
-d, --dir : String required
The output directory
-r, --recurse
Recursively search directories
-l, --jshint : String
Specify a jshintrc file for JSHint linting
-t, --title : String
Title of the report
-D, --date : String
Time to use as the report date (seconds, > 9999999999 assumed to be ms)
-n, --noempty
Skips empty lines from line count
-e, --eslint : String
Specify a eslintrc file for ESLint linting
`

Example

`shell
es6-plato -r -d report src
`

> Note for Windows Users:
If you are on Windows, you might want to put your glob in quotes if you use a tool such as cygwin, conemu or some other emulator, and you are also targeting files in directories, otherwise the emulator might incorrectly expand the glob before it is handled internally by es6-plato. For instance, if you want to use /src//.js and the results are ignoring the root try './src//.js'` instead.

About

This is currently a reimplementation of the older plato, and started as a fork from https://github.com/deedubs/es6-plato, but has since been heavily modified.
After seeing it was unpublished on npm and also wanting to add more features, I Asked if it would be alright for me to publish and continue the work.
This project uses eslint, not jshint for default linting.

I have switched to the typhon-js module since it properly parses classes.
