Initializing objects from proc parameters

Yea the `construct` macro handles that, though it still requires writting the fields twice.

> As the author of constructor Yes, Yardanico already told us. But from my current understanding your macro currently can initialize objects only with default constants. Which I need rarely as my defaults are generally binary zero. What I sometimes need is initialization with runtime values as

Wow I really like your defaults. Should be part of nim!

Initializing objects from proc parameters

As the author of constructor I really have to agree with the "Oh god it's so tedious to right it so many times" so I solved it. Recently just made my new `defaults` macro which makes it so you only have to type the definition once! Feast your eyes on macro magic! import constructo

If only we had a macro system so that you could have any amount of syntax sugar you need...

Yea, I'm also annoyed with the need to type code twice. Actually it's the types typed twice, the keys typed **4 times** , 1) in object definition 2) in `init` args 3 and 4) in object initialisation as `key: key` type HedgedStock* = object id*: string evol*:

You should check out , it does something similar to this

That's very similar to what was proposed by @alexeypetrushin here:

Initializing objects from proc parameters

I am converting some Ruby code to Nim and got proc initialize(s: Step; prev, nxt, id: int) = s.prev = prev s.next = next s.id = id s.radius = 0 # default for incident net s.outer = false Run The first 3 assignments in the proc are a pattern
