astyle

Source code indenter, formatter, and beautifier for the C, C++, C# and Java programming languages. Upon running, a copy of the original file is created with an ".orig" appended to the original file name. More information: http://astyle.sourceforge.net.

  astyle {{source_file}}
• Apply the Java style with attached braces:
  astyle --style=java {{path/to/file}}
• Apply the allman style with broken braces:
  astyle --style=allman {{path/to/file}}
• Apply a custom indent using spaces. Choose between 2 and 20 spaces:
  astyle --indent=spaces={{number_of_spaces}} {{path/to/file}}
• Apply a custom indent using tabs. Choose between 2 and 20 tabs:
  astyle --indent=tab={{number_of_tabs}} {{path/to/file}}
