• Introduction

  A Virtual Labs /Experiment/ is a systematic collection of learning resources for Engineering students to learn about a single topic in a subject. Each experiment consists of some theory and reading material, interactive simulations and quizes or tests. The authoring process may be different for each institute but the end result is a collection of web-pages that are published together as an /Experiment/.

  Each experiment is a part of of /Lab/. A /Lab/ is a conceptually a collection of /Experiments/ related to a subject. A /Lab/ is published as a collection of web-pages that provide an entry point for a user to learn about that subject. The list of experiments included in a lab provides links to all the available experiments.

  Creating a publishable lab along with all it's experiments, is a process that involves a lot of manual effort that does not add any value to the lab itself. Labgen is a command-line tool that helps in avoiding all the repeatative effort involved in creating a lab from individual experiments and other lab content.

  The following processes are supported by labgen:

  1. Generation of Lab pages.
  2. Deployment of Lab
  3. Build and Deployment of Experiments

  The automated build and deployment of experiments is supported only for experiments generated using the /Phase 3 experiment authoring process/ (link?) defined by IIT-B.

• Requirements

  1. node 12.12.x
     • Download link: [[https://nodejs.org/en/download/][node]]
     • recommended to install via [[https://github.com/nvm-sh/nvm][nvm]]
  2. npm 6.11.x

• Setup

** Install Dependencies

#+BEGIN_SRC bash

npm install

#+END_SRC

• Generating Lab Pages

** Create Lab Repository

Create a new lab repository on [[https://github.com/virtual-labs][Github]] or clone and existing one. The repository should be empty.

** Initialize Lab Descriptor

To start with the process of lab generation, you need a /Lab Descriptor/.

/Lab Descriptor/ is a json file the contains data for lab pages and other information for lab and experiment deployment. [[file:lab-descriptor.org][This]] document describes the structure of a lab descriptor file.

** Complete and Verify Lab Descriptor

Fill all the values in the =<path/to/lab/repo>/lab-descriptor.json= file generated above and create a pull-request to get the lab-descriptor approved.

*** LD Verification Example

Continuing the [[Init Example][init]] example, lets see how to submit the completed
lab-descriptor for verification.

In the lab repository, switch to a new branch and edit the json.

#+BEGIN_SRC bash
cd ~/virtual-labs/myNewLab
git checkout -b lab-descriptor
editor lab-descriptor.json
#+END_SRC

After filling the json push the file to remote and create a pull
request.

#+BEGIN_SRC bash
  git add lab-descriptor.json
  git commit -m "lab-descriptor for verification"
  git push origin lab-descriptor
#+END_SRC

Once this pull request is merged to master, do not make any new
changes to the lab-descriptor.

** Run All

From the /Phase-3-Lab-Template/ repository, run the following.

#+NAME: labgen-generate #+BEGIN_SRC bash npm run labgen -- --release minor <path/to/lab/repo> #+END_SRC

• Building an Experiment

To build an individual experiment first clone the experiment and run the following:

#+BEGIN_SRC sh cd <path/to/experiment/repo> git clone https://github.com/virtual-labs/ph3-lab-mgmt/ cd ph3-lab-mgmt npm install npm run build-exp ../ #+END_SRC

Or, from with this repository:

#+BEGIN_SRC sh npm run build-exp <path/to/exp/repo> #+END_SRC

The first method is useful when running the script from the github actions pipeline.

The experiment can be found in the =build= directory with the experiment repository location.
