I've been using it for Python mainly but I find it's really helpful. It can often infer arguments for functions or functions to use based on the variable names. I've used Ruby lots in the past and I think it would work just as well based on my experience. I would give the free version a try and see what you think.
I've been using TabNine for a few weeks, and it's really cool how well it works. My first "woah" moment with it was writing a function where the first thing I wanted to do was take the length of the array, and once I started typing
def foo(bar):
n
it suggested the entire completion of "= len(bar)". It has a really cool way of picking up your coding style that makes it stand out to me.
Thinking about it more, I wonder how useful that type of autocompletion is for those who can type fast. I wonder how much time it takes my brain to context switch away from "code authoring and typing mode" to recognize the " = len(bar)" in the autocomplete options list. It seems like it would be faster to just type out the " = len(bar)" for those who type a solid 60+ words a minute?
I'm trying it out now. If it works well $30 is nothing for this magic. Especially in VSCode, my favorite editor. I have a problem with many languages not having the support I need. And I also don't have the best memory, so autocompletion makes me much faster and costs me less frustration with Googling.
Aside from the obviously fake jittering gauges, it seems like whenever I reset the page the pointer goes to about 68% and then after 5-10 seconds jumps to 77%. Not sure if it's caching a number and then updating or supposed to make me stay on the page.
