problem using gen-class and using the class name in the same file
Hi
I try to compile a file that generate a class with gen-class that include
class name
at different places in the file here is a simplified version of the
problem:
lein init test-gen
then edit the core.clj with
--
(ns test-gen.core
(:gen-class
:name test-gen.Tata
:init pre-init
:constructors {
[Integer] [Integer]
[test-gen.Tata] [Integer]
}
)
)
(defn -pre-init
[x]
(test-gen.Tata. 9)
9)
--
add :aot [test-gen.core] in project.clj
then compile with lein compile:

The problem seems to be that i am using a class that doesn't exist yet.
If i comment all lines referring to test-gen.Tata; compile; uncommment
those lines; compile; again then it works.
Is there a way a better to
Re: problem using gen-class and using the class name in the same file
Yes exactly, i need a constructor which require an instance of the same
class as parameter and i need to create new instances of this class in some
methods (i implement an abstract class that require this).

There are two things that I've notice about your code that could probably
be the cause. In the :constructors section of :gen-class, you're refering
to test-gen.Tata although it doesn't exist yet. The -pre-init function also
tries to call a class that doesn't exist yet.

Re: problem using gen-class and using the class name in the same file
It seems that only the constructor is the problem. it there is workaround to solve this ? I have several gen-class calls each need a constructor with an instance of the same class as parameter.

Re: problem using gen-class and using the class name in the same file
It works for me!! Thanks josh, meikel and kelker for your answers. Le mercredi 12 juin 2013 18:10:37 UTC+2, joshro...@gmail.com a écrit : I was messing around recently with creating a Builder class using gen-class and ran into the same issue since each set* method returns this. I'm pretty sure it's a chicken and egg issue: the class doesn't exist yet but you need to specify it in the gen-class ... I reworked your example a little bit, see if this fixes the problem: https://www.refheap.com/15708 and https://www.refheap.com/15709 I used Object in gen-class, and then check the type in the init.
