[Q] What would be the best approach or design for converting this common lisp code?

[Sungjin Chun]

Hi,

The code repo is https://github.com/wzrdsappr/trading-core .

If you look at the code, the main trading agent is designed using inheritance and the main

operation (consume) function mainly depends upon mutable update of agent's states.

As far as I know Clojure does not permit attribute inheritance and this kind of state update is

not recommended approach. 

What would be the best approach in Clojure?

Thank you in advance and sorry for my poor english.

Hi Sungjin,

Although Clojure draws from the long history of Lisps, it is very much its own language. In particular, the emphasis on immutable data by default makes Clojure very different from both Common Lisp and Scheme. Porting code from another Lisp to Clojure will usually require a complete redesign.

Based on looking very briefly at the code you linked to, it looks like it might be some kind of agent-based simulation. Clojure's Agents may be something worth exploring: http://clojure.org/agents

Thank you for your response. I thought that the transducer based approach combined with core.async channel could be a solution.

I'll check for the agent thing.
