Artistic style is a console program that receives information from the command line. The format of the command line is:
astyle [options] SourceFile1 SourceFile2 SourceFile3 [ . . . ]
The block parens [ ] indicate that more than one option or more than one filename can be entered. They are NOT actually included in the command. For the options format see the following Options section.
Example to format a single file:
astyle --style=allman /home/user/project/foo.cpp
Example to format all .cpp and .h files recursively:
astyle --style=allman --recursive /home/user/project/*.cpp /home/user/project/*.h
Another option will format a single file and change the name:
astyle [options] < OriginalSourceFile > BeautifiedSourceFile
The < and > characters are used to redirect the files into standard input (cin) and out of standard output (cout) - don't forget them! With this option only one file at a time can be formatted. Wildcards are not recognized, there are no console messages, and a backup is not created. On Windows the output will always have Windows line ends.
Options
Not specifying any option will result in 4 spaces per indent, no change in bracket placement, and no formatting changes.
Options may be written in two different ways.
Long options
These options start with '--', and must be written one at a time.
(Example: '--brackets=attach --indent=spaces=4')
Short Options
These options start with a single '-', and may be concatenated together.
(Example: '-bps4' is the same as writing '-b -p -s4'.)
