# This configuration file contains a selection of the available options provided by the formatting tool "Artistic Style"
# http://astyle.sourceforge.net/astyle.html

# If you wish to change them, don't edit this file.
# Instead, copy it in the same folder of file "preferences.txt" and modify the copy. This way, you won't lose your custom formatter settings when upgrading the IDE
# If you don't know where file preferences.txt is stored, open the IDE, File -> Preferences and you'll find a link
