Re: [sc-users] sorry wrong topic - DATA FILES

I write archives....

you can

[2,3,4,5,6].writeArchive("arc");

a=Object.readArchive("arc");

also find it useful that you can archive instances....


//class code put into SCClassLibrary
<x-tad-smaller>Test
{
var <>a,<>b;
*new{^super.new.a_(2).b_(5)}
}

//

c=Test.new
[c.a,c.b]
c.writeArchive("test")
d=Object.readArchive("test")
[d.a,d.b]

this way you can have nicely named, automatically savable and organized data structures</x-tad-smaller>
<x-tad-smaller>
Test
{
var <>a,<>b,<>path;
*new{^super.new.a_(2).b_(5).path_("test")}
save{this.writeArchive(path)}
}</x-tad-smaller>

<x-tad-smaller>c=Test.new
[c.a,c.b]
c.save
d=Object.readArchive("test")
[d.a,d.b]
</x-tad-smaller>
dig into class writing, it is the most transparent and readable it can get (for me)
