What's new in Agena 2.5.3:

  • Due to an idea from Serbia, a new type check metamethod '__oftype' has been introduced for all structures and for userdata. If a type check metamethod exists for such an object, then it is run with calls to the :: and :- operators. If the object does not satisfy the criteria defined in the metamethod, then Agena returns `false`.
  • This also applies to function calls: if the check fails, Agena issues an error, e.g.:
  • > mt := [ '__oftype' ~ proc(x) is return type(x) = pair and left(x) :: number and right(x) :: number end ];
  • > duo := 1:2; > setmetatable(duo, mt); > f := proc(x :: pair) is return x end; > f(duo): 1:2 > duo := 'a':'b';

Agena is an open source and easy-to-learn procedural programming language designed to be used in scientific, linguistic, educational, and many other applications.

Moreover, Agena's syntax looks like very simplified Algol 68 with elements taken from Lua and SQL.

The interpreter provides fast complex and real arithmetics, flexible data structures, efficient text processing, intelligent procedures and package management, plus various configuration facilities.
