the error message also sugget that your process may not have started quickly enough. How do you deploy on heroku? Do you have a Procfile? What does it say? Do you prepackage on push, or recompile everything on startup? On Monday, 27 July 2015, Divyansh Prakash wrote: > Hi! > > I had written a po

Re: Creating jar specific defaults

You're probably using clojure.java.io/file (looks for files on the filesytem) instead of clojure.java.io/resource (looks for files in the classpath). On 20 June 2015 at 16:41, Timur wrote: > Hi everyone, > > I want to specify some defaults for a library that I pack as a jar, for > instance standa

Re: Joda Time version conflict? "Initializing JollyDayHoliday for SUTime"

Assuming there is a version that works for both dependencies, you can manually fix it in your own project.clj. Your own direct dependencies will override transitive ones. Otherwise, as far as I can tell, you're stuck. Maybe you can try using an older clj-time? On 29 June 2015 at 21:00, wrote: >

Re: How to share the large files that can not fit in Github?

There is also a git annex command. I have not use it personally, but my understanding is that it is essentially keeping a hash of the file (and perhaps a url to download it?) in source control in git, without adding the file itself. That way git can tell when the file has changed, without pollutin

Re: Basic question: what's the difference between "require as" and "use as"?

Unless you have a very compelling reason, just don't use use. It's mostly a historical accident that's kept there for backwards compatibility. And try to avoid :refer :all if possible. There are legitimate use-cases for it, but outside the REPL they are pretty rare. On Tuesday, 23 June 2015, Ritc

Re: stuartsierra/component is oop, can clojure namespace self init to solve the dependencies?

OOP does not mean mutab... erh... anything, really, but there is an argument to be made for calling an immutable blob that carries data and the operations to act on it an "immutable object". If every "mutative" operation returns a modified copy of the object, you can have immutable OOP. On Thursda
