[AST] question about marshal_write_*() fxns
For those of you who don't know, I am sprinting on the AST branch here on PyCon. Specifically, I am fleshing out Python/compile.txt so that it can act as a good intro to new users and as a design doc. But one of things I am not sure of is what the marshal_write_*() functions in Python/Python-ast.c are used for. I assume they output to the marshal format, but there is mention of a byte stream format and so I thought it might be that as well. Anyone know which one it is? -Brett

I believe the idea is that they can be used to move an AST back and forth between Python "space" (e.g. you could build an AST using Python code and then marshal it and send it to the C compiler). Neil

Jeremy emailed me and said the same thing. Name should be changed, though, to prevent this confusion. Jeremy thought maybe the name should be changed. Here are some ideas for a different name (thinking in terms of what the name would be changed to for the prefix of the function names): - byte_encode - linear_form - zephyr_encoding - flat_form - flat_prefix - prefix_form - scheme_form =) For those that don't know and it wasn't obvious from the names, the format is a prefix-based, linear form. -Brett

Ah, so that's why it's quiet this week :)

Given Neil & Jeremy's answers, perhaps "linear_ast_*" or "bytestream_ast_*" would work as a new prefix? Cheers, Nick. -- Nick Coghlan | ncoghlan@email.com | Brisbane, Australia --------------------------------------------------------------- http://boredomandlaziness.skystorm.net
