[Swift-user] example of @length

[Heather Stoller]

Hello,

Does anyone have an example of how to use @length?

I have tried a few things, most recently
@length(inputfiles)
without success.

Cheers!
Heather


complete script below.

type file;

file inputfiles1[] <ext;exec="mapper.py",filename=@arg("in1")>;
file inputfiles2[] <ext;exec="mapper.py",filename=@arg("in2")>;

app (file o) cat (file i1, file i2)
{
        cat @i1 @i2 stdout=@o;
}

foreach j in [0:@length(inputfiles1)] {
        file c<concurrent_mapper;
                prefix="map.",
                suffix=".out">;
        c = cat(inputfiles1[j], inputfiles2[j]);
}
