ELENA 1.6.1 released

ELENA 1.6.1 is out now

This major release includes changes in the language syntax, several critical bug fixes and enhancements in the language library code.

1.6.1 is not binary compatible with the previous versions (due to changes in ecodes and a grammar)

multi-threading support

GCX (a revised garbage collection) is now thread-safe

changes in ecodes (ELENAVM byte codes)

  • several “big” commands are split, to reuse existing ecodes (disptach, redirect)
  • new ecode – popn

simplified syntax to create a group

instead of old style syntax

#group(events'EHandler, BtmSave) += …
it is possible to use the following syntax
BtmSave~events'EHandler += ..

#define command without an alias

it is possible to include another namespace without providing a namespace shortcut

#define std'basic'*.

Integer << 2.

new compiler hint syntax

instead of old style

#hint(subj:mysubject)
#class MyClass {…}
a new syntax is introduces
#class(subj:mysubject)MyClass {…}

#hint is no longer supported

the new hint syntax should be used

several major changes in an expression syntax

The following syntax

A verb:B::C
should be replaced with
A verb:(B::C)

An argument list could be used in initializing expression
A::&arg1:B &arg2:C

#inline alias(A, B, C) verb:D
