# Welcome to the InSpec Tutorial

## The InSpec whaaaat?  What is this thing?

This is an Angular 2 app that uses Xterm (https://github.com/sourcelair/xterm.js/) to simulate a terminal.
'Ok, but why?'
To give people an easy quick introduction to InSpec and all it can do! Give it a try,
learn a thing or two, tell us what you'd like to know more about, and have fun exploring!

## How to run it

run `npm install` to load dependencies
run `npm run start` to open in your browser @ localhost:8080

## How does it work???

Well, let me tell you a story of a file named `tutorial.yml`, who lives in a directory named `content`. This kind, informational file was full of content, and oh so desired to spread its knowledge. But it knew not how to do so, for it was a simple yml file.

Then, from around the corner, came a sweet little ruby file, whose only wish was to help people
do the things they needed to do. It's name, in fact, was `run_simulator_recording.rb`, and it lived in a nearby directory named `scripts`. And, aha, a match was found.

And so `run_simulator_recording.rb` kindly took `tutorial.yml` by the hand, and said 'let me help you! I can parse you, and help you help others'.
And thus it began...
`run_simulator_recording.rb` parsed `tutorial.yml` to find the instructions and commands that are noted in the instructions. After that, the real fun began: `run_simulator_recording.rb` worked and worked to format the commands and prepare them.
She created `.json` files for instructions and commands, and used [Train](https://github.com/chef/train) in the background to run the commands and record the output to some .txt files in the `app/responses` directory.
Pleased with her work, `run_simulator_recording.rb` turned to her friend the webapp, and said to her: 'take these json files, and show them to the people.'

Webapp then went and found her friend xterm, and said, why let's do this together, for two heads are always better than one!
And so webapp said to her dear friend angular2, please help me make this work! and angular2 came running, as friends always do.
And so angular2 met xterm, and as they shook hands, they knew they would be good friends together. So they put their heads together,
and made some decisions about what each one's role would be. Xterm claimed responsibility for creating the terminal view,
reading the user's input, and displaying it.  App then explained she could take that final user input sent over by xterm and
and transform it into a regular expression, which she could then use to match against the information in the `commands.json` file,
matching the user's input against the key and then retrieving the associated value's txt file.
And it was so. :)

## How to generate content for tutorial/update the tutorial

To generate content for the tutorial, update the `tutorial.yml` and/or `commands.yml` file and
run `bundle exec rake update_demo` from the root of inspec project. This will create/update three json files (`commands.json` and `instructions.json`)
and the `.txt` files for the `app/responses/` directory (generated from the commands included in the `tutorial.yml`). Those are the files required by the app to create the demo content.
