Multi-line comment style in rtwbuild code generation.

I am using Simulink/Embedded Coder to generate C++ code from MATLAB functions in MATLAB R2018a.

I have observed that multi-line comments

% My
% multi-line
% comment

result in the following C++ code

/*  My */
/*  multi-line */
/*  comment */

by setting the 'CommentStyle' parameter to 'Multi-line' in the Simulink Coder model configuration parameters.

Especially for multi-line comments along several lines, the trailing */ in each comment line looks rather cluttered. Is there a way or parameter to get something like the C++ code below?

/*  My
 *  multi-line
 *  comment
 */

I updated the release, since the issue is also occuring in MATLAB R2019a (Update 1).

It seems fairly easy to fix yourself in the resulting file (although I must admit the parameter name sounds like it should do it already for you).

Maybe it only does it for comment block (the %{ and %}).

Hi Rik, thx for your answer. I tried it with MATLAB R2021b (Update 2) and Embedded Coder. I am still getting the same behavior.

A multi-line comment

% This is
% a multi-line
% comment.

is translated to

/*  This is */
/*  a multi-line */
/*  comment. */

and a block comment

%{
This is
a multi-line
block comment.
%}

is translated to

/* { */
/* This is */
/* a multi-line */
/* block comment. */
/* } */

I would suggest submitting a bug report or an enhancement request. The parameter name sounds like it should generate the style you indicated.

Maybe this is to increase portability of code. If know that for C not all compilers will accept multi-line comments.
