I want to make some changes to REPL.jl present at `Julia-1.3.1\share\julia\stdlib\v1.3\REPL\src` (local installation). However the changes aren’t being reflected when I actually run it. Do I need to run an intermediate build command? Here is the `versioninfo()` output:

> Julia Version 1.3.1

You can either run `make`, or use the trick from here: [Pkg.jl/README.md at master · JuliaLang/Pkg.jl · GitHub](https://github.com/JuliaLang/Pkg.jl/blob/master/README.md#using-the-development-version-of-pkgjl)

If you don’t have a source build, you can edit the files and then do

```julia
using Revise, REPL
Revise.track(REPL)

```

Still isn’t working. May I have the instructions for the source build ? Maybe changing some lines of the file isn’t enough. I need to build it entirely.

My local installation has REPL.jl at the path `Julia-1.3.1\share\julia\stdlib\v1.3\REPL\src` , whereas it is present under `\stdlib\REPL\src` at GitHub. Would a different path prevent Revise from reflecting the changes ? It is not working out currently.

Yes, it is path-dependent. You can unpack `Revise.watched_files` to figure out where it’s looking for the files:

```julia
