Re: Calling a java function with multiple implementations based on type

Clojure will use reflection to find *a* method, but if you want it to pick the correct one from multiple overloads, you need to give clojure type hints so it knows the correct static types of the parameters. At least I think that's how it works. When I've hit this before, I've just played with typ

Calling a java function with multiple implementations based on type

Hi folks - I met some strange behaviour today using the clj-ssh library - but it looks like it might not be the library's fault as such. If I call (add-identity agent {:private-key-path "foo" :passphrase "bar"}) the clj-ssh library (eventually) calls a java method: (.addIdentity agent "foo" "bar"

Only a lateral quick comment: Node.js + NPM (its package manager) has a nice version management. If your module A needs D version 0.1, and module B needs D version 0.2, no problem. Both versions are added, and A loads version 0.1, meanwhile B loads version 0.2. The trick is the search path for mo
