Re: How to get a value of a var in Java

Vars extend IDeref so one way to get the value of a var is to call .deref on it: user> (def a) #'user/a user> (defn ab [] 1) #'user/ab user> (.deref (clojure.lang.RT/var "user" "a")) 2 user> (.deref (clojure.lang.RT/var "user" "ab")) #function[user/ab] On Fri, Jun 18, 2021 at 7:12 AM ru

Re: Routing for a non-web-app

For 'routing' specifically, if you want a more formal system we used state machines in the past and recently Clojure has a really nice additional possibility there - https://github.com/lucywang000/clj-statecharts. For general UI programming if you are using javafx then I really like cljfx -

Ngwua, Looking through the caesium bindings just mentioned, it appears the author dynamically creates an interface and then you can simply ask the native library to instantiate a concrete implementation of that interface .

Clojure integration with JuliaLang

There are hybrid options available in the form of https://github.com/clj-python/libpython-clj -- I am one of the primary authors of this tool. One pathway perhaps is to use clojure to do your scraping and orchestration (and frontend display) and just use python from command line scripts to do

Hey Ru, Renaming x to anything will result in roughly the same error in your function. The problem is that your instance macro needs to know the classname at compile time. As x is a runtime variable, the compiler cannot see the literal value of x at compile time. Put another way, in your test

We published a blog post about one specific but important tactic I used when writing libpython-clj in order to allow python to call clojure functions. I don't think this is necessary knowledge to use panthera or libpython-clj but it is a key piece to building a new binding to a C system elsewhere

Re: Java Interop on steroids?

eglue, 1. I think this is a great idea if it is really necessary. I would be in favor of a reify++ alone to simplify things. I find reify amazing at code compression and heavily use it via type specific macros to implement interfaces that for instance support a particular primitive type. 2.

Re: Go block starvation issue
