I'm finally getting round to [submitting changes](https://github.com/Metaxal/quickscript/pull/72) to the [quickscript](https://docs.racket-lang.org/quickscript/index.html) plugin that is included in Dr Racket.

My guide to doing this is usually [Tutorial: Contributing to Racket](https://blog.racket-lang.org/2017/09/tutorial-contributing-to-Racket.html) on the [Racket Blog](https://blog.racket-lang.org/)

I used `raco pkg update --deps fail --link --scope installation --type dir <my quickscriptdir>` and it seemed to update nicely, but sadly the plugin fails (error below) when I launch DrRacket.

I'm sure I've missed something simple but it's late and I can work it out. Any guidance or advice greatly appreciated.

Best regards  
Stephen

I think you need a newer version of Racket. The git version of quickscript depends on some stuff that's in the git version of DrRacket. The simplest thing (on a non-windows machine) might be to git clone the racket/racket repo and do "make" at the top-level, get some coffee, and then come back. Then a `raco update --clone quickscript` (usually done in the `extra-pkgs` dir that you've created inside your checkout of racket) will get you a directory you can run usual git commands in.

hth!

Thanks @robby

You advice worked perfectly

But to provide a little more details, and invite criticism in case there is a better way.

1. used GitHub desktop to get a copy of the latest Racket repo on my machine (I'm sure there is a git command but I'm lazy)
2. ran `make`
3. ran DrRacket to configure the path for the new install (I'm still lazy)
4. Opened a new terminal in the new `racket` folders
5. ran `raco pkg update --clone extra-pkgs/quickscript`
6. copied the changes from my fork/branch to `racket/extra-pkgs/quickscript` (I'm sure there is a way to do this with git but I'm still lazy)
7. Open DrRacket, menu: Scripts\>compile
8. Scripts eyes
9. Declare that my changes are tested
