Re: hello world question !!!

Thanks. I have been using clojure, as an example, on discussions on Quora. In essence, extrapolating from Lisp, pre-web, to clojure. Now, is that a huge leap? I don't expect so. I saw the approximation of something built on Lisp re-done (or attempted, anyway) via objective-C. The trade offs were ob

Hey, clojure world, your work got this old Lisp guy excited. Keep up the good work.

There once was a man named Gustava Whose Clojure code smelled just like Guava He tried to use gen-class Which made it smell stink-ass So he went back to working in Java Hardy-har-har. Containers long for bytecode on disc. You can minimize it, but you have to have it to bootstrap the Clojure runti

Re: hello world question !!!

I think you can use lein-ring or lein-uberwar to package any ring based clojure web app into a War. But, a War is just a zip file with a known set of files and directory structure. So depending on your needs, you could create it yourself too. -- You received this message because you are subscr

Damien: A good starting point for a simple web server might be to use lein new pedestal-service Then you can do lein uberjar to get a jar ready to run. Or check the README for running local dev with a local REPL. If instead you want a WAR, you can switch from pedestal.jetty to pedestal.immutan

James, Thanks. I saw a writeup mentioning Leiningen that I will go back to. It is not the 'toy' issue that concerns me. It is that all sorts of browsers exist as well as a whole slew of different types of users. And, if I am going to push something down to a remote device, I want to expect that i

Re: hello world question !!!

It's been a couple of years, but (from what I remember) it works great. Immutant (or maybe it's wildfly?) has an option to deploy "exploded .WAR files." I'm very fuzzy on the details, but it seems like the basic choices were either: 1) deploy an uberwar with AOT (advantage: faster startup time

Re: hello world question !!!

This is really "just" a +1 for using Leiningen. TL;DR: Just start with `lein new app hello-world` and get an editor integrated with your REPL quickly. Come back to these sorts of things later, if/when you still think they're worthwhile. I came to clojure from the python/c++ world, with just eno

Damien, This is just an aside. Thanks for the question. I have not even tried Clojure, yet. So, this is good for me to follow. BTW, I have done Java (since the '90s) and so know of the 'coffee' stains everywhere. Yet, given the Lisp basis, I want to see how to make Clojure easier for the cau

I haven't deployed an application written in Clojure to a server as a WAR file before, so can't speak from experience, but I am sure others here probably can. Hey, others, have you deployed a Clojure application via a WAR file without using AOT compilation, with only Clojure source code packaged i

The docstring for compile says that "The source for the lib must be in a proper classpath-relative directory", so unfortunately you can't just create the namespace in the REPL and compile it from there. The tutorial on t

but i am in this situation, i wrote application in Scheme (Kawa,Bigloo) ,LisP that ran on an apache tomcat server, the application is deplyed in war files , they are precompiled ,with Kawa or Bigloo Scheme, and also use regular Java class compiled with Java8. They never ran in REPL ,all the test

yes i had tested . (point) in classpath and later added clojure/example which is not a good idea as the namespace is already clojure.examples.hello, already clojure.examples will be converted in clojure/examples but what must i do then? where must i put this hello.clj: (ns clojure.examples.hell

Re: hello world question !!!

Just a note that at the top of the documentation page you mention, it says: "Clojure compiles all code you load on-the-fly into JVM bytecode, but sometimes it is advantageous to compile ahead-of-time (AOT)." I would venture an estimate that most people who use Clojure do so without using AOT compi

Re: hello world question !!!

paths have to reflect the package and be relative to the class path, so if "clojure/examples" is on the classpath, and the namespace is clojure.examples.hello, the file needs to be in "clojure/examples/clojure/examples/hello.clj" On Fri, Oct 13, 2017 at 10:13 AM Damien Mattei wrote: > i did not

Re: hello world question !!!

To pedantically specific, clojure compiles all of your coffee to be code in memory, but the 'compile' function expects to find a file on disk, and create a class file on disk. Using gen-class in the repl is a no-op. On Fri, Oct 13, 2017, 07:48 James Reeves wrote: > Maybe this is a dumb question,

Maybe this is a dumb question, but do you have a file "clojure/examples/hello.clj" on the classpath? Since that's what the exception is complaining about. On 13 October 2017 at 15:09, Damien Mattei wrote: > hello, > > i'm new to clojure, just installed it on a CentOS box, > > and try to compile
