I'd be grateful to hear from other emacs users regarding your workflows for Julia development, e.g. if you want to write a Julia package what emacs packages, setup and workflow help you to be the most productive?
I find a combination of emacs for modules; iJulia for experimenting, testing, debugging, examples; and REPL for help works very well. Typically, I sketch something in IJulia, then convert it to a module, which is further edited in emacs, but keep test codes in Julia, and eventually I also move the test codes to a module. Christoph
