[Scilab-users] News: Scilab 6 Beta, VISA Toolbox, Embedded World 2016

[Eric Dubois]

Thanks for the answers.

I share Samuel opinion that the changes from Scilab 5 to Scilab 6 are much
important than previous ones (and I have experienced all of them since
starting with Scilab 2.6!). In the previous cases, functionnalities became
obsolote; this time they change... This is a much more difficult to deal
with

I do not know, Samuel, how you plan to review all your codes. As for me
this should be a daunting task:
- I have arorund 1400 Scilab functions, representing something like 70 000
lines of code, containing around 20 000 additions or subtractions; so I
cannot imagine reviewing all this code;
- Another avenue is to devise a battery of tests covering all possible
cases; this should be less costly, but could miss some relevant cases; and
this means in my cases extending the battery of tests, a useful task
anyway, but also costly

The command warning stop seems to be a good idea for dealing with this
problem, but it has also major drawbacks: you should put it in the .start
file, to prevent users to generate wrong results, but this will also stop
programs that work perfectly. So I do not think it will help dealing with
my concern that inexperimented users could generate wrong results with a
toolbox such as mine. Am I missing something?

Anyway, I fully agree with Samuel that more and more publicity MUST be done
about how to translate Scilab 5 code and modules into SCilab 6 code and
modules, and maybe they will convince me that I have overestimated the
problems...

Regards

Éric
