hello.jl defines the hello() function, but you need to call it to get some output. For instance, function hello() println("Hello World") return end hello() hello() will print "Hello World" twice. On Monday, May 9, 2016 at 10:59:05 PM UTC-4, rich2...@gmail.com wrote: > > Newbie

To expand on what Jacob said, you can read a DataFrame into an in-memory SQLite table and then run SQL commands on that. However, unless you really need to use SQL there's probably a way to do the same operation faster (and with less code) using native DataFrame operations. If you can provide

It's possible to have a macro in Julia that emulates Python decorators. But it's a separate question whether you really want to do it, there might be more efficient/elegant ways to achieve the same in Julia for a specific use case. Here's a macro that emulates Python decorators and an example

When Julia installs, it creates a link in the Start menu. If you right click on the Julia icon, you should be able to figure out the path to the Julia executable, julia.exe. That path should be ending with ...\bin\julia.exe. On Fri, May 6, 2016 at 6:56 AM, Yu Tony wrote: >
