* Perlito5 (Perl 5 compiler):
- more than 1700 tests
- Parser:
-- emit the same error messages as 'perl' in more places
-- expanded support for prototypes, regex, v-strings
-- track variable redeclarations and variable scopes
-- add the variable type to AST nodes ("real sigil")
-- "Perlito5X" namespace re-implements CPAN modules that are not possible (or not easy)
to support directly in Perlito - such as Data::Dumper.
Some modules are inlined in the parser - such as "vars" and "constant".
-- add "<<>>" (Perl 5.22)
-- support for "__LINE__", "__FILE__", and tracking the current line number
-- more pod implementation details, such as "=encoding"
-- fix return value for if/unless modifiers
-- command line - implement "-n", "-p", "-M", "-m", fixed "-I"
-- use a smaller grammar-grammar
-- use a faster calling convention in grammar
-- shorter AST node names
- Perl5-to-Javascript compiler:
-- file operators (nodejs)
-- create regex variables $1, $2, ...
-- implement regex /e and /ee modifier
-- /usr/bin/node displays the message's text and a backtrace (Shlomi Fish)
-- initial overload implementation
-- flip-flop operator, split, tr
- Perl5-to-Java compiler:
-- statements: while() and if()
-- containers: hash, array, scalar; autovivification
-- lexical and global variables
-- Java data types: String, long, double, boolean
-- Perl data types: closures, references
-- initial implementation of regexes
-- native Java objects and classes using: package Perl::Package { import => "java.class" }
-- typed lexicals - mapped to imported Java classes: my Perl::Package $java_variable
-- Java::inline
* Perlito6 (Perl 6 compiler):
-- no significant changes
-- Go backend no longer works
-- Python bootstrap still works
-- instructions in "README-perlito6" need some update (replace "d8" with "node")
dev 2014-05-30

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):
