SMOP Mold: Revision 8
SMOP Mold is a register based interpreter implementation
A Mold block(?) is composed of three parts
- the number of registers used by the program (not counting the ones used to put constants or the 3 special ones)
- constants - which are put into registers
- opcodes
The registers 1,2,3 are initialised with
- interpreter
- identifier
- captures
Mold opcodes
- call invocant,identifier,named,positionals,target
- call2 responder,capture,target
- goto label - jumps to label
- br register,iftrue,iffalse - jumps to iftruel if the native bool in register is true to iffalse otherwise
Example in p6 syntax what would $*OUT.print("hello world\n") be translated to
my $out;
constant $OUT = "$*OUT";
constant $print = "print";
constant $curly = "postcircumfix:{ }";
constant $SMOP__S1P__RootNamespace = $SMOP__S1P__RootNamespace;
constant $hello_world = "hello world\n";
$out = $SMOP__S1P__RootNamespace.$curly($OUT);
$out.$print($hello_world);
