[Matlab-emacs-discuss] percent-brace

[Xavier R. <xav...@gm...>]

Matlab gives the possibility to insert comments which span several lines 
inside percent-brace %{ %}

It seems that matlab-emacs does not handle  correctly indentation when 
this feature is used. Here is an example:

function y= f(x)
% first comment
%{
    second comment: induces unwanted indentation.
    %}

    % Third comment

    y=x

end

This indentation does not correspond to the one produced by the matlab 
editor. I wonder if this is something that could be easily changed.  
When writing code with others, it is important to have same indentation 
policy and matlab own editor then sets the standard.

Thank you for your help.

Hi Xavier,

For me, block comments work ok as long as they are not part of the first block of comments.  Basically, the indentation engine doesn't know when the line that doesn't s tart with % is part of a comment or not.

I attached a patch that makes the basic indentation for this case work, but I'll guess it will have performance implications.  It will take some more effort to make sure indentation performance doesn't get too broken.

Thanks
Eric
