}You can change the way Jzon formats the file by defining a Jzon::Format and setting the members it holds.
There are two pre-defined formats that you can use: Jzon::StandardFormat which formats the file as above and Jzon::NoFormat which doesn't use any formatting at all.
- bool newline - If true sub-nodes will be written on separate lines.
- bool spacing - If true ":" and "," will be trailed by a space.
- bool useTabs - If true the lines will be indented by tabs instead of spaces.
- int indentSize - The number of spaces or tabs to indent with.
Note: to disable indentation, set indentSize to 0.
