Specify Indent Style for C/C++ Code - MATLAB & Simulink (original) (raw)
Main Content
If you have an Embedded Coder® license, you can control the indent style and indent size in C/C++ code generated from MATLAB® code. Indent style controls the placement of braces. Indent size controls the number of characters per indentation level.
You can specify the K&R indent style or the Allman indent style. Both styles:
- Place the function opening and closing braces on their own lines at the same indentation level as the function header.
- Indent code within the function according to the indent size.
- For blocks within a function, place closing braces on a new line at the same indentation level as the control statement.
- Indent code within a block according to the indent size.
The K&R style and the Allman style differ in their placement of the opening brace for a control statement. If you want the opening brace on the same line as its control statement, select the K&R style. Here is code that has the K&R indent style:
void addone(const double x[6], double z[6]) { int i; for (i = 0; i < 6; i++) { z[i] = x[i] + 1.0; } }
If you want the opening brace on its own line, select the Allman style. Here is code that has the Allman indent style:
void addone(const double x[6], double z[6]) { int i; for (i = 0; i < 6; i++) { z[i] = x[i] + 1.0; } }
Specify Indent Style Using the MATLAB Coder App
- Set Build type to one of the following:
Static Library (.lib)Dynamic Library (.dll)Executable (.exe)
- Click Settings.
- Set Indent style to
K&RorAllman. - Set Indent size to an integer from 2 to 8.
Specify Indent Style Using the Command-Line Interface
- Create a code configuration object for
'lib','dll', or'exe'. For example:
cfg = coder.config('lib','ecoder',true); % or dll or exe - Set the
IndentStyleproperty to'K&R'or'Allman'. For example:
cfg.IndentStyle = 'Allman'; - Set the
IndentSizeproperty to an integer from 2 to 8. For example:
