What tools are needed to collaborate on code development effectively?Objectives
Provide an overview of all the different tools that will be used in this course.
The first section of the course is dedicated to setting up your environment for collaborative software development. In order to build working (research) software efficiently and to do it in collaboration with others rather than in isolation, you will have to get comfortable with using a number of different tools interchangeably as they’ll make your life a lot easier. There are many options when it comes to deciding which software development tools to use for your daily tasks - we will use a few of them in this course that we believe make a difference. There are sometimes multiple tools for the job - we select one to use but mention alternatives too. As you get more comfortable with different tools and their alternatives, you will select the one that is right for you based on your personal preferences or based on what your collaborators are using.
Here is an overview of the tools we will be using.
Common Issues & Fixes When Running Tools
Check the list of common issues, fixes & tips if you experiencing problems running any of the tools you installed - your issue may be solved there.
Command Line & Python Virtual Development Environment
We will use the command line
(also known as the command line shell/prompt/console) to run our Python code and
interact with the version control tool Git and software sharing platform GitHub.
We will also use command line
to set up a Python virtual development environment and isolate our software project
from other Python projects we may work on.
Note: some Windows users experience the issue where Python hangs from Git Bash (i.e.
python causes it to just hang with no error message or output) -
see the solution to this issue.
Integrated Development Environment (IDE)
An IDE integrates a number of tools that we need to develop a software project that goes beyond a single script - including a smart code editor, a code compiler/interpreter, a debugger, etc. It will help you write well-formatted & readable code that conforms to code style guides (such as PEP8 for Python) more efficiently by giving relevant and intelligent suggestions for code completion and refactoring. IDEs often integrate command line console and version control tools - we teach them separately in this course as this knowledge can be ported to other programming languages and command line tools you may use in the future (but is applicable to the integrated versions too).
We will use PyCharm in this course - a free, open source IDE.
Git & GitHub
Git is a free and open source distributed version control system designed to save every change made to a (software) project, allowing others to collaborate and contribute. In this course, we use Git to version control our code in conjunction with GitHub for code backup and sharing. GitHub is one of the leading integrated products and social platforms for modern software development, monitoring and management - it will help us with version control, issue management, code review, code testing/Continuous Integration, and collaborative development.
Let’s get started with setting up our software development environment!
In order to develop (write, test, debug, backup) code efficiently, you need to use a number of different tools.
When there is a choice of tools for a task you will have to decide which tool is right for you, which may be a matter of personal preference or what the team or community you belong to is using.
