Hy reader macros #377 Added first iteration of reader macros Refactored defmacro and defreader Added test inn hy/tests/lex/test_lex.py Added new test in hy/tests/native/tests Added new test in hy/tests/macros. changed the error given in the dispatch macro and added some handling for missing symbol and invalid characters 2013-12-15 17:47:24 +01:00			`from hy.macros import macroexpand`
Overhaul macros to allow macros to ref the Compiler This allows macros to take a keyword dict containing useful things by defining a keyword argument. This allows us to pass in new objects which might be handy to have in macros. This changeset refactors module_name to become `compiler`, so that we can pass the compiler itself into the macros as `opts['compiler']`. This allows the macro to both get the macro name (`compiler.module_name`), as well as use the compiler to build AST. In the future, this will enable us to create "super-macros" which return AST, not HyAST, in order to manually create insane things from userland. For userland macros (not `defmacro`) the core.language `macroexpand` will go ahead and make a new compiler for you. 2015-12-23 21:13:18 +01:00			`from hy.compiler import HyTypeError, HyASTCompiler`
