Controles evaluation of identifiers / variables The evaluation brackets work a bit like $eval though you can add multiple things to evaluate at different levels at once.

Example:

 var %a = sometext
 var %b = % $+ a

Now %a is "sometext" and %b is "%a"

 echo -a [ %b ] returns %a

This would echo "%a" since %b is evaluated once. Note that this is the same as just echoing %b

 echo -a [ [ %b ] ] returns sometext

This would echo "sometext" since %b is first evaluated to "%a" and then %a is evaluated to "sometext".

Now lets see how it works out in more complex forms.

 echo -a [ %a $+ [ %b ] ] returns sometext%a

This would echo "sometext%a" In this case %a is evaluated once and so is %b. Note that echoing [ %a $+ %b ] won't work.

 echo -a [ %a $+ [ [ %b ] ] ] returns sometextsometext

This would echo "sometextsometext" since %a is evaluated once and %b twice.


Another example:

 var %name = fish
 var %surname = bot
 set % $+ %name $+ . $+ %surname m00
 echo -a % [ $+ [ %name ] $+ . $+ [ %surname ] ] returns m00

This would set %fish.bot to "m00" and echo "m00".
