Maybe this post will be useful for you: [julia vim tutorial for newbies](https://discourse.julialang.org/t/julia-vim-tutorial-for-newbies/36636/7). ( but maybe you already know these things)

As others wrote above Revise doesn’t give you anything here (as far as I know). It would be useful if you wrap the pieces of code in your script in functions. Then if you use `includet` the function definitions will be automatically updated the next time you call them from the REPL. As far as I know, the way you are using the script, `include` and `includet` are equivalent in their end effect.

EDIT: maybe I’m wrong with what I wrote above. I thought Revise tracks only changes in function definitions, but from a quick test it seems that it also tracks some changes in stuff happening at top-level (e.g. assigning a new value to a global variable). Anyway I only ever used it for tracking functions so I’m not sure.
