ChangeLog

dev  2012-04-12

* Perlito5 (Perl 5 compiler):

-- namespace Perlito5X contains versions of CPAN modules adapted for perlito
-- option "-B" is now the default; this executes immediately:  perlito5 -e 'say "ok"'
-- option "-MO=Deparse":
   $ node perlito5.js -Isrc5/lib -MO=Deparse -e ' while (1) { say "works" } '
-- environment variable PERL5LIB=src5/lib now works

- parser:

-- autoquote hash-keys fix
-- string interpolation in m//
-- accept underlines inside numbers

- javascript backend:

-- AUTOLOAD
-- tie() - TIEARRAY, STORE, FETCH
-- string increment
-- negative index in array
-- more file and process operations: chdir, unlink, close, exit
-- control functions: next, last, redo, break
-- more functions: rand, printf, sprintf
-- "continue" blocks
-- GLOB references

- perl5 backend:

-- requires v5.10


* Perlito6 (Perl 6 compiler):

-- updated method hyper syntax to use >>. instead of .>>


9.0  2012-04-11

* Perlito5 (Perl 5 compiler):

- parser:

-- there is now an internal "grammar API"; new words can be added to the grammar from inside perl5 modules;
   The non-standard "token" grammar was moved to a module
-- here-docs
-- new Perl5-in-Perl6 backend (experimental)
-- new option -Bjs/-Bperl5
-- new option -Cast-perl5
-- added option -I
   Note: -I./src5/lib is required to compile the compiler and also to run some of the tests
-- runs some tests from the perl5 test suite (pmurias++)
-- implemented prototypes (function signatures)
-- "use", import/unimport; "use strict"/"no strict"

- perl5 backend:

-- use native data structures and ops

- javascript backend:

-- works on node-js (pmurias++)
-- @ISA and inheritance
-- %ENV, @ARGV
-- simple regexes (using javascript native regex)
-- symbol tables/typeglobs
-- references
-- "local", "our"; goto &sub
-- wantarray; each; __PACKAGE__
-- native javascript can be accessed with JS::inline('string')
-- reduced generated code size; emitted code is more optimized and better formatted
-- cleanup unused modules from the browser backend

- javascript backend regressions:

-- the d8 shell (v8 javascript) doesn't support some file system functions needed by the compiler
-- perlito5 calling convention is incompatible with native javascript
   The last commit using native javascript calls is "e1e3316b"

* Perlito6 (Perl 6 compiler):
- compiler namespace moved from Perlito to Perlito6

6.0  2010-07-27
- Ruby backend bootstrap.
- more tests

5.0  2010-07-19
- Python backend bootstrap.
- use variable assignment instead of binding - that is, use '=' instead of ':='
- 'use' - all backends can now use Test.pm

- 'loop' 
- regex quantifiers
- Lisp backend now bootstraps with the 'util/mp6.pl' compiler

4.1  2010-03-24
- floating point numbers

4.0  2010-03-20
- Go backend bootstrap.
  The Go backend was updated to the latest Go language spec. 
- Perl5 backend optimized; 30% faster

- New compiler options to create binary executables
- Currently the stable backends are: Perl5, Javascript, JVM, Lisp, Go.
  See README for bootstrapping instructions for all backends.
- Removed support for features that are not standard Perl6.
