Artistic Style (command line: astyle) is a tool to format Java code (i.e. fix your indentation and new lines).
It also works on: C, C++, C++/CLI, Objective‑C, and C#.
Quick start: astyle *.java
Type astyle *.java at the command line on CSIL to use a software package called “Artistic Style” to automatically fix the indentation of your Java code to match a variety of style conventions.
As an example, if your directory contains:
cs56-rational-ex01 pconrad$ ls
LICENSE Rational.java Main.java README.md
cs56-rational-ex01 pconrad$
After you run astyle *.java, you’ll have:
cs56-rational-ex01 pconrad$ ls
LICENSE Main.java.orig Rational.java
Main.java README.md Rational.java.orig
cs56-rational-ex01 pconrad$
where the .java.orig file are the originals, and the .java files are the newly formatted files.
Advanced usage
You can use command line arguments to control which style is used, and to apply astyle recursively to an entire directory tree:
For example:
| Command | Explanation |
|---|---|
astyle --style=google --recursive src | Apply Google style to all files under the src directory (and all subdirectories of src) |
Install on Mac
To install on Mac, first install MacOS: Homebrew, then type:
brew install astyle
