hscript

Parse and evalutate Haxe expressions.

Usage :

var expr = "var x = 4; 1 + 2 * x";
var parser = new hscript.Parser();
var ast = parser.parseString(expr);
var interp = new hscript.Interp();
trace(interp.execute(ast));

In case of a parsing error an hscript.Expr.Error is thrown. You can use parser.line to know the line number.

You can set some globaly accessible identifiers by using interp.variables.set("name",value)

Advanced Usage

When compiled with -D hscriptPos you will get fine error reporting at parsing time.

You can subclass hscript.Interp to override behaviors for get, set, call, fcall and cnew behaviors.

You can add more binary and unary operations to the parser by setting opPriority, opRightAssoc and unops content.

You can use parser.allowJSON to allow JSON data.

You can use parser.allowTypes to parse types for local vars, exceptions, function args and return types. Types are ignored by the interpreter.

You can use new hscript.Macro(pos).convert(ast) to convert an hscript AST to a Haxe macros one.
