| 30 """Compile an .idl file to Blink V8 bindings (.h and .cpp files). | |
| 31 | |
| 32 We are porting the IDL compiler from Perl to Python. The plan is as follows. | |
| 33 We will temporarily have two build flows (see ../derived_sources.gyp): | |
| 34 [1] Perl: deprecated_generate_bindings.pl, which calls: | |
| 35 deprecated_idl_parser.pm => deprecated_code_generator_v8.pm | |
| 36 [2] Python: idl_compiler.py, which calls: | |
| 37 IDL lexer => IDL parser => Python object builder => | |
| 38 interface dependency resolver => IDL semantic validator => | |
| 39 C++ code generator | |
| 40 | |
| 41 We will move IDL files from the Perl build flow [1] to the Python build flow [2] | |
| 42 incrementally. See http://crbug.com/239771 | |
