Just add // at the end of the line, like this, to force the formatter to keep it that way. I use phantom comments to deal with that. It adds a verifyGoogleJavaFormat task to be used in continuous integration to verify formatting.Ī common problem when auto formatting coding is with newlines.
Jgrasp auto format code#
You just need to add it to the adle and it can format the code at compile time with something like pendsOn 'googleJavaFormat'. It includes a validate attribute that can be used in continuous integration, perhaps with a build property, to validate that the code is formatted correctly. You just need to add it to the pom.xml and it will format the code at compile time. The important thing is what they produce, the code, which should have no references to any IDE. You can let the developers use whatever IDE they want. The code style, and the tool support for that, is completely separate from any IDE used.All decisions in this code style is carefully taken considering how diffs will appear in files where it is applied.It can even optimize imports, sorting and removing unused imports. It takes all decisions regarding formatting of Java code.Applied when building and verified in continuous integration. The course coding standard is supported by Checkstyle, which is an automated tool that works with the jGRASP IDE and the Web-CAT program grading system to automatically detect style errors based on the rules or checks. There are plugins for Gradle and Maven so that it can easily be integrated in the build process. A coding standard consists of guidelines that are used by developers when writing source code to ensure a consistent format.If it is up to me, I choose Google Java Format. While it is easy for a reviewer to see that brackets are incorrectly positioned, other things may not be as obvious. There is no way, as far as I know, to verify Eclipse-formatting as a step in a continuous integration flow.Then you may start getting unnecessary diffs in commits after an upgrade. The semantics of the settings in the code style may change between versions of Eclipse (I have seen it!).They will have to have Eclipse installed just to use it for formatting. All people are not productive in Eclipse, some might for example be using InteliJ or NetBeans.The code style is imported to Eclipse from an XML-file and some clients also use Workspace Mechanics to setup save actions properly.ĭefining the code style in Eclipse is a very bad idea: The most common solution to this, among the clients I've been working with, is to use a code style defined in Eclipse.
Re-formatting it in a new commit makes it harder to maintain the project because things like git blame will show the re-format commit, not the original feature commit.If some developers use something like save actions in Eclipse then they will have a hard time keeping the lines unchanged when working on the file. Keeping it means you have to live with faulty formatted code.This is a problem that I find incredibly annoying! If such code is not blocked, from making it into shared branches, you will have the choice of keeping it or fixing it. if followed!Ī single person, in the project, can lower the quality significantly by not formatting the code correctly. That is great and improves code quality a lot. Most projects, that I work with nowadays, have a defined code standard that includes how the code should be formatted.
