Indentation is done with tabs, not spaces. Tabs are 4 spaces wide.
Braces follow Allman-style with brace-less single-line statements being allowed and encouraged when it does not make things less readable:
There are no spaces between parenthesis and function names, if, for, etc.
Names can be either in UpperCamelCase
or snake_case
, but it should be consistent across the whole project.
