Hi all,
What would you think about a feature describe as follows?
We coud add a specific calling sequence for lines function (e.g
lines(-1000)) that will switch automatically the display of Scilab to
the "short" mode [1000x1000 constant] for a matrix (or hypermatrix)
having a dimension greater that 1000.
I agree with Serge that my initial proposal using existing lines() flags
and just adding a sign convention is not good, for the reason he
explained, and also because such a convention would be closed, would
prevent any extension for further paging or overall formating modes.
But i disagree about extending format() instead, because presently
format() works only on formating numbers (for disp() and string()). This
would turn its role confused.
I would rather advice to keep lines() to implement new paging modes --
because it is already its job, not the format()'s one : Scilab's
format() is not Matlab's one --, but to extend its size.
Hence, L = lines(); L(3)=100 could be a new flag thresholding
full/abstract modes.
In the same way, a non-wrapping mode could be tuned through L(4),
instead of highjacking L(2) with any sign convention.
Finally, if a compact output mode without extra blank lines should be
implemented & switched, lines() would also be involved, not format().
Samuel
PS : format() could also be extended, in the first place for instance to
replace xset("fpf",v) -- that has still no set() equivalence ; but this
is another discussion.

Re: [Scilab-users] Accidentally displaying huge matrices
With the caveat that the threshold size that determines what gets displayed in its entirety and what doesn't is tunable, this works for me. The root problem that I'm addressing is the pitfall of doing something that prints for ever and ever just because I forgot the ';'.

I think using lines(-1000) or a similar solution is not a good solution
because as I said lines function does not rules the display of a single
variable, but the display of all output generated by an instruction
In my opinion it should be better to extend the format function adding
an optional argument or modifying the function to allow syntax like
format("type","v","digits",10,"max_lines",100)
format("max_lines",100)

It's a fairly new language that aims at solvaing the two language problem, ie reducing the gap between interactive, easy to use and prototype in but also slow languages (scilab, matlab, python, ...) and more efficient and less friendly languages (C, Fortran, ...). It's new and still evolving a lot but quite interesting (more info at julialang.org).

Me too!
If there is a way to interrupt the display of a huge variable, I'll be happy to
know it.
If not, it's worth writting a feature request.
It's a common mistake to forget a ";" when doing some data processing/debugging on the
fly and it's such a pain to wait forever for your "fat-fingering" to finish.

Hello,
Here's the behavior of Julia in such a situation, it displays dots in
order that the matrix fits the console :
julia> a=rand(1000,1000)

[Scilab-users] Accidentally displaying huge matrices
If you're working with something humongous and you do some operation that displays, it takes forever before your mistake is done displaying. E.g., if x is 10 elements long and you type y = exp(x) instead of y = exp(x); So I have two questions: First, is there a way to get it to stop? ctrl-C does not do the job. Second, if not, could someone file an enhancement request, or remind me how to do it? TIA -- Tim Wescott www.wescottdesign.com Control & Communications systems, circuit & software design.
