 +
* (90 minutes) Checkstyle (http://checkstyle.sourceforge.net/) is one of a number of static analysis tools that provides a measure of the health of a codebase.

** Read the ~150 items checked, and determine if each should be included or excluded from the standards for your group project.  For each item included, state appropriate parameters.
  
* look at three versions of the same code

Title

The Need for Style Guides

Overview

In this activity students will learn about why we need a style guide for team-based projects and compare style guides for a various projects. Based on this experience, students will develop a style guide for their team.

Prerequisites

Knowledge of basic regular expressions is helpful to understand the checkstyle documentation.

Learning Objectives After successfully completing this activity, the learner should be able to:
  • Explain how a style guide contributes to a team project.
  • Develop a style guide for a project.
Process Skills Practiced


Background

Working by themselves on small projects convinces students that coding style his little relevance. As they begin work on HFOSS projects, they need to begin to build an appreciation for the place of a standardized coding style.

This topic is an opportunity for active debate about coding style, but is also a lesson in the need for accepting standards - even if they are not your preference.

Directions

The following activities should be completed by the student before coming to class:

Ideas for in-class activities:

  • Have students work in their groups to compare their assessment of the checkstyle items. Each group should develop a single style for their work.

(optional) Install checkstyle for your favorite IDE:

(optional) Add checkstyle to your build (ant, maven, etc.)
