Hey All, MacroPy is basically finished in its current state, as a proof of concept and bundle of demos. Next steps include breaking the macros themselves into separate project and polishing the core into a solid foundation for others to bui

Author here, I just put up a Detailed Guide: https://github.com/lihaoyi/macropy#detailed-guide That goes into more detail of how macros are written, and walks you through writing a simple but useful macro (the quicklambda macro). This sho

Yeah, we haven't looked at performance at all. "The Wonderful Thing About A Dancing Bear Is Not How Well He Dances, But That He Dances At All" We'll get to teaching him to dance well later!

Yep, there's an issue for that! https://github.com/lihaoyi/macropy/issues/14 I've also gotten a basic implementation working in the CPython REPL, which requires you to run a function `macro_repl()` before you can use them. A Macro powered

Laziness; we already had it installed. That's what a lot of other people are using. It's not that we don't like Python3; their ASTs are considerably simpler (e.g. no print statement), they have importlib, and a bunch of other nice things. I

I'd argue that "fields as a string with spaces inside, or maybe a list of strings" is changing language semantics quite a bit. We're used to namedtuples doing it like this now, but if namedtuples didn't exist, "fields as a list of strings w

- The classes do inherit from object, iirc - We know the nesting is controversial; whether it will remain in its current form has yet to be seen. I think there is some merit in this way of doing it, we know others disagree
618.
by lihaoyi 13y ago
We do take it seriously; it's a hard tradeoff between Novelty and Utility. Given that the whole point of macros is to change the semantics of the Python language, this (valid) criticism applies not just to case classes but macros in general

It definitely looks funny from a python point of view; it's inspired by ADTs and OCaml. Perhaps it would be better to leave them to be accessed via a qualified name (e.g. `List.Nil`, `List.Cons`). This is all up for debate.

Author here. The `<<` operator is being abused to mean "bind", so the right side is a normal expression (constructing a Foo and Bar) and the left side matches it to a particular "shape". The purposes of pattern matching is to replac

Yep, it's a pity they won't. Even so, many of the macros (e.g. log/trace) are the sort of thing that will be super useful even if they never get checked into Version Contrl. I know I spend a lot of time peppering `print "A"` `print "B"` sta
