Project description

ABSTRACT:

A community website plays an essential role in an open-source organization because it spreads the idea of offerings that the community provides, their precious contributions, their skills, their documentations, their tutorials, etc. So, my project will aim to increase the usability and easiness for all the open-source contributors by transferring and updating the book project areas content, i.e., docbook content, REST API documentation and pbench markdown content to reStructuredText format such that it can be hosted on the modern, community readthedocs.io site. This project will also benefit the community contributors by allowing them to change and extend this content more easily. As well as, as a stretch goal, the diagrams in the documentation will be improved to give them a more professional look.

PROPOSAL:

  1. OVERVIEW: The Performance Co-Pilot documentation currently exists in several different formats. These include PCP books in docbook format, REST API in manpage format, and pbench guides in markdown format. So, the organization’s current maintainer group identified that they need a solution that is as maintenance-free as possible, and that allows the developer community to be entirely focused on maintaining its content in a streamlined and easy way. So, according to the current needs of the organization, I will implement the following goals during this Google Season of Docs:

    1. Converting docbook content to reStructuredText format and hosting it on readthedocs site.
    2. Converting REST API documentation from manpage to developer-friendly format, i.e., reStructuredText format and hosting it on readthedocs site.
    3. Converting pbench MarkDown content to reStructuredText format and hosting it on readthedocs site.
    4. Stretch goals would be to improve the diagrams present in the documentation.
  2. IMPLEMENTATION: Currently, the Performance Co-Pilot documentation is not present in a specific format. Whenever the content of the documentation needs to be changed, it needs to be changed by a restricted set of users. It is not that easy for the active community members to change and extend the documentation’s content.

I will let the organization overcome these limitations during this GSoD with the help of reStructuredText format, Read the Docs (RTD), and Sphinx.

Read the Docs (RTD) simplifies software documentation by automating building, versioning, and hosting our docs for us. It is a hosting platform for Sphinx-generated documentation. It takes the power of Sphinx and adds version control, full-text search, and other useful features. It pulls down code and doc files from Git, Mercurial, or Subversion, then builds and hosts our documentation. We’ll use GitHub in our project as it’s the most commonly used system for accessing code.

To get started, we’ll create a Read the Docs account, and link the GitHub account. Then we’ll select the GitHub repository we’d like to build documentation for, at which point the magic happens.

Read the Docs will: - Clone our repository. - Build HTML, PDF, and ePub versions of our documentation from our master branch. - Index our documentation to allow full-text-search. - Create Version objects from each tag and branch in our repository, allowing us to host those as well optionally. - Activate a webhook on our repository, so when we push code to any branch, our documentation is rebuilt.

Sphinx is an authoritative documentation generator that has many great features for writing technical documentation, including: - Generate web pages, printable PDFs, documents for e-readers (ePub), and more all from the same sources. - We can use reStructuredText to write documentation. - An extensive system of cross-referencing code and documentation. - Syntax highlighted code samples. - A vibrant ecosystem of first and third-party extensions.

I will start with converting the two PCP books which are present in docbook format to rst format, following the conversion of REST API documentation from man page format to rst format, then conversion of pbench markdown content to rst format and in the end, hosting all of these on the readthedocs site. The stretch goals would be to improve the diagrams in the documentation.

2.1. Conversion to reStructuredText format: The first step will be to convert the documentation content into reStructuredText format. Each chapter will have a separate rst file, which will contain the content of that chapter only. For example, Performance Co-Pilot User's and Administrator's Guide book include eight chapters. It means there will be eight different rst files corresponding to those eight chapters. The name of the rst file will be the same as the chapter name to avoid any confusion in the future. A list of figures, tables, and lists of examples will be there in three different rst files. The rst content will be thoroughly hyperlinked in the same way it is currently present. The same thing will be used for the REST API documentation and pbench content. All the necessary things, such as bold, italic, underline, bullet points, tables, font size, code-style, image size, alignment, etc., will be taken care of while converting the contents into rst format.

2.2. Integration of rst with Sphinx:


ReadtheDocs uses Sphinx and reStructuredText (rst) as defaults. As Sphinx is pre-installed in my system, I will start with creating a directory inside the project (named as Performance Co-Pilot Documentation) to hold the docs: $ cd /path/to/project $ mkdir docs

After that, running sphinx-quickstart in there: $ cd docs $ sphinx-quickstart

This quick start will walk through creating the necessary configuration; in most cases, we can just accept the defaults (but when required, we can make the essential changes in the configuration file). When it’s done, we’ll have an index.rst, a conf.py, and some other files. In index.rst, I will add all the necessary details about the Performance Co-Pilot and will create headings for both the books, REST API documentation, and pbench guides. When the user will click any of the headings, it will open up all the documentation materials under that heading.


NOTE: The design of the index page will be according to the mentors' and community members' consent and will be changed according to the needs and requirements.

The index.rst will be built into index.html in our documentation output directory (typically _build/html/index.html). Once we have Sphinx documentation in a public repository, we can start using Read the Docs by importing our docs.

When we’ll add any .rst file in our documentation, then corresponding to that file, three other files will be generated, one in doctrees folder with .doctree extension, second in Html folder with .html extension, and the third one in html/_sources folder with .rst.txt extension.

  1. HOSTING THE DOCUMENTATION: Hosting of documentation on the internet consists of two steps: 1. Importing the documentation: As a first step, I will connect the Read The Docs account with GitHub and import our documentation project to build. 2. Building the documentation: Within a few seconds of completing the import process, the code will automatically be fetched from our public repository, and the documentation will be built.

  2. WEBHOOKS: The primary method that Read the Docs uses to detect changes to the documentation and versions is through the use of webhooks. Webhooks are configured with our repository provider, such as GitHub, and with each commit, merge, or other change to our repository, Read the Docs is notified. When we receive a webhook notification, we determine if the change is related to an active version for our project, and if it is, a build is triggered for that version.

In this way, anyone (admins, mentors, community contributors) can change, extend or maintain the community documentation, and no particular restricted set of users will be needed to take care of what should be added to the documentation or what should be removed from the documentation.

  1. THEMES: Themes, layouts, designs, and other HTML functionalities like search will be as per community needs and guidelines. In the community bonding period, I will discuss all these with the community members.

  1. STRETCH GOAL: As a stretch goal, I will improve the diagrams present in the documentation. Currently, the diagrams are mostly simple black-and-white drawings. I will introduce more color, shading, scaling, consistency, and a generally neater / more professional look to the images.

To serve this purpose, I will use draw.io (or any other tool with the consent of the mentor).

As a Proof of Concept, I have improved one of the diagrams present in the documentation with the help of draw.io. Please find it here: https://docs.google.com/document/d/1CUukNgwh6PvvUz9pOTOEEfi659HiyJvMHNyxumKZVfc/edit?usp=sharing

PROOF OF CONCEPT

I have converted a small part of the PCP book (docbook format) into the rst format and hosted it on the readthedocs site. Please find it here.

Website - https://pcp-books.readthedocs.io/en/latest/ Code - https://github.com/arzoo14/PCP_Books_Demo

I have also configured webhooks in the code repository with the help of which, the changes made in the code repository will get reflected in the website.

TIMELINE AND DELIVERABLES

COMMUNITY BONDING PERIOD [ August 17 - September 13, 2020 ]

I will spend this time familiarizing myself with the community, going through the documentation, and discussing many things with the mentors to make sure no bad decisions are made early in the process. I will discuss the themes, layouts, designs, other functionalities like search, navigation bar, etc. with the mentors and the community members during this period. The decision for the name of the project and whether there will be a single website for hosting all three topics or three different websites corresponding to the three topics will be discussed during the community bonding period.
