Don’t be afraid of using tools to help enforce coding style. Web developers have an unprecedented number of tools at their fingertips today, and many of them can help ensure that a coding style guide is being followed. These range from command line tools that are run as part of the build, to plugins that work with text editors. Here are a few tools that can help keep your team on track:
Eclipse Code Formatter The Eclipse IDE has built-in support for code formatting. You can decide how specific languages should be formatted and Eclipse can apply the formatting either automatically or on demand.
Checkstyle A tool for checking style guidelines in Java code, which can also be used for other languages.
These are just a small sampling of the tools that are currently available to help you work with code style guides. You may find it useful for your team to share settings files for various tools so that everyone’s job is made easier. Of course, building the tools into your continuous integration system is also a good idea.
