Well, v4 is finally out, and you all have a big job ahead of you to
digest all of the new features (18 pages of release notes!).
Here's a few of my favorite new features. There are many, many more,
but this is just a taste.
String formatting
-----------------
String formatting is truly world class now. Check out these sections
of the Interpreter chapter:
- String Literals
- String Interpolation
- Heredoc Strings
- String Format Operator
Variable fun
------------
You can now declare 4D process/interprocess variables on the fly,
even in a compiled database! In conjunction with the 'execute in 4d'
command, this will eliminate the need to create wrapper methods to
implement missing commands.
You can now add an element to an array and address it at the same
time like this:
array longint($longs; 0)
$longs{} := 7
$longs{} := 13
It doesn't get much easier.
Collections
-----------
You can now declare an array within a collection directly without
having to create a separate array and then assign it, like this:
array longint($myCollection{"ids"}; 0)
You can also make collection items that don't yet exist the target of
commands like SELECTION TO ARRAY, like this:
selection to array([companies]id; $comp{"ids"}; [companies]name; $comp
{"names"})
Have fun!
