How to hide _some_ commands in published m-files?

Andres — Thu, 09 Oct 2008 14:22:01 -0400

Hi,

is there any kind of switch to hide a specific command in a published m-file? E.g. with a source file like this...

?
%% Demo file

% assign constants
a = 3;
b = 5;

% algorithm
c = a./b;

disp(['Result for c: ' num2str(100*c) '%']) % hide this
?

I want all commands to show up in the published file except for the disp(... command, but I want its output
?
Result for c: 60%
?
to appear.
Thanks for your thoughts,
Andres

There may be a more sophisticated way to do this, but one easy way is to
write a short script file and call that script file instead of DISP:

displayResult;

where displayResult.m is:

% begin displayResult.m
disp(['Result for c: ' num2str(100*c) '%'])
% end displayResult.m

Thanks for your idea, Steve. I'd then have to write a script or function for any kind of code I want to hide, but it would definitely make the published file look a bit better.

Maybe the only 'more sophisticated' method would be to post-process the html-file, i.e.

- add a keyword comment to each line of code to hide, like '% *hide*'
- write a function publishAndHide.m that publishes the m-file, looks for the keyword in the source part of the published file (after '##### SOURCE BEGIN #####'), and finally removes the corresponding lines in the html-part ...

Humph, i'll think about if it's worth the effort.
Does anybody know if the part of html-code containing one line of matlab-code could possibly span over more than a single line (wrapping,...?)? If not, finding the html-code to delete should be quite easy by directly searching the html lines (but there might be other pitfalls).
Any further thoughts about this are appreciated.

(Btw, just now I found a similar thread
