Contributing to Updated Pharo By Example (vol 1)

This book follows the fork-and-pull GitHub workflow for contributions:

  1. Fork the repository

  2. For each modification, create a quick topic branch named in the form of...

    example: git checkout -b dz_PharoTour_update_screen_snapshots

  3. Make commits to that branch. When you're ready, make a Pull Request

  4. The request will receive comments/corrections, and will be merged into the main repo.

More info about contributing to this book (including Pillar syntax, setting up LaTeX, etc) can be found in the CONTRIBUTING.md file.

Please send any comments, suggestions, or questions to the pharo-dev mailing list (see also the Get Help section of Pharo.org).

Style Guide

This book is written in Pillar markup. If you are not familiar with it please check the pillar-documentation. See also:

Images

Images (screenshots and diagrams) use Pillar image syntax:

+Image caption>file://figures/filename.png|width=80|label=fig:label+

For example:

+A stream positioned at its beginning.>file://figures/abcde.png|width=100|label=fig:abcde+
  • The width parameter is required (percentage of the screen).
  • Place the files in the figures directory of the chapter they are in.
  • The label should begin with fig:
  • When taking screenshots (PNG format), please compress them (you can use TinyPNG for easy and lossless compression)

To reference an image: Figure *@fig:abcde* (renders to Figure 3.8, for example).

Scripts and Code Blocks

For scripts, method definitions and other code blocks:

[[[language=smalltalk|caption=Hello World in a Transcript|label=src:helloWorld
	Transcript show: 'hello world'; cr.
]]]

Note that the label starts with src:.

To reference code blocks, use Script *@scr:helloWorld* (similar to Figures).

Chapter and Section Reference Links

Whenever you refer to other chapters of the book, please use the Pillar internal link syntax and the chapter name. (The cha: in the id is to denote that it's a chapter, to differentiate from a section id.) For example:

Chapter *: A Quick Tour of Pharo>../PharoTour/PharoTour.pillar@cha:tour*

A list of chapter ref link code is provided, to easily copy and paste, in the Chapter Progress / table of contents above.

General Style Guidelines

Please keep in mind the following:

  • When possible, hard-wrap lines at 80 characters (e.g. Meta-Q in Emacs, Cmd-Alt-Q in Atom). This is a common open-source documentation convention, and helps with viewing GitHub-generated diffs. However, due to Pillar limitations, ordered and unordered list elements must be on a single line to be correctly parsed. Those can be left un-wrapped.
  • Only one space between sentences.
  • Avoid periods in section titles. (For example, this section is titled "Style Guide" and not "Style Guide.")
  • All inline code mentions (objects, messages, variables, packages) should use the Pillar monospace notation: ==Object==.
