Cannot use

[Kalimehtar]

Hello!

I installed ming, but it doesn't work for me.

I got an error after #lang ming

...\Racket\8.9\pkgs\ming\core.rkt:15:4: mapping/racket/list: undefined;
 cannot reference an identifier before its definition

The same error, if I write

#lang racket
(require ming/core)
(require (mingize racket/list))

What do I wrong?

Sorry for the late reply, I missed the issue notification.

I tried that, it works for me. Did you run that as a script? If it did not work as a script, can you try that within the REPL?

And also, a simpler way for your code would be like below:

#lang racket
(require ming/racket/base)
(require ming/racket/list)

And there are other two points that need to be in the user's head always:

1. I may change the mappings at any time, for your stable usage, I recommend using the git reference for the installation: raco pkg install "https://github.com/yanyingwang/ming.git#c88c0574ddda9a777bd8b996ef6b5468553639e3"
2. the ming package is just and only works, the error messages and lots of other things need to be enhanced in my following time. since the mappings weigh more than others for me, so I may still put energy into that part.

I tried different Racket versions.

Ming works on Linux/racket-8.7 and doesn't work on WIndows/racket-8.9

./raco pkg install ming

from my trying with a Windows, this is related to the difference of Windows path from the UNIX system. Even though I can fix that part of code, it's better for me to refactor it by explicitly defining them.

please try it again, it works on my PC now.

Now it works.

谢谢
