Bug fixes

• Length 1 tuple (1,) and length 0 set set() was not recorded correctly.
• Import and __all__ did not match.
• The __getitem__ was not correctly defined when a slice is used as indices.

Improvements

• Fixed many typing things.
• Cythonized.

Changes

• Mock object for easier Expr construction. Instead of writing like Expr("getattr", [Expr("getattr", ...), b]), you can use m = Mock("m") and create Expr object by m.a(0, "s").
• Full support of Python 3.7, and add tox test.

Bug Fixes

• The __eq__ method will return False instead of raise Exception to make macro recording safer.

Bug Fixes

• Fix incompatible annotations for Python 3.8 (and add tests).

New Features

• New ast type supports: break, continue and raise.
• Modules will be registered to Symbol whenever it is converted into a Symbol so that you'll not have to pass module object when you call eval. For instance, instead of macro.eval({"np", np}) you only have to call macro.eval().

Changes

• The "type" argument in Symbol is removed because it is never used.

Bug Fixes

• Hash of Symbol was not completely safe.
• mModule did not return constant values correctly (such as np.pi).

New Features

• register_type and Symbol.register_type can be used as a decorator.
• Symbol.var("x") can create unique variable x.
• Many missing AST types are supported, such as % (mod operation), += (in-place operations) and unary operations.
• Validators are implemented in Expr to assert correct grammar for certain header (although they are not perfect). For instance, Expr("getattr", [Symbol("x"), "name"]) used to return :(x.'name') but now it returns :(x.name).
• Many special methods, such as __int__ and __hash__, are correctly converted to int(X) in macro.
• Macro can used as a field of a class. Unique Macro object will be created for different instances.

Changes

• Attribute _last_setval is moved to Macro.
• Method type definition is changed to delayed definition.
• Type mapping of symbol now uses dictionary as much as possible.
• The type keyword argument in Symbol constructor is deleted because it was not used.

Bug Fixes

• Boolean operations (and and or) could not be parsed.

New Features

• Support function definition, if, for, and many other expressions.
• Macro.callbacks attribute for expression-added callbacks.
• flags keyword argument to specify what kind of expressions will be recorded.

Changes

• Macro inherits Expr but head is fixed to Head.block to simplify module.

New Features

• Support string parsing using ast.
• optimize method of Macro can remove unused returned variables. It makes macro looks better.

Changes

• Head is different from that in v0.1.0, thus may be inconsistent.

This is the first release.
