I'm trying to use (debug-repl) in the following simple program:
#lang racket
(require debug/repl)
(define (add a b)
(debug-repl)
(+ a b))
(add 4 5)
If I run this in Dr. Racket, then I get a repl prompt as expected.
However, I'm using Greg Hendershott's racket-mode for emacs, where it blows
up with the following:
;
; Welcome to Racket v7.8.
;
>
; cache-set!: contract violation
; expected: path-string?
; given: #f
; in: the 6th argument of
; (->
; path?
; syntax?
; syntax?
; string?
; namespace?
; path-string?
; any)
; contract from: (function cache-set!)
; blaming:
d:\data\prj\EmacsUnification\emacs\home\.emacs.d\elpa\racket-mode-20200924.1506\racket\syntax.rkt
; (assuming the contract is correct)
; at:
d:\data\prj\EmacsUnification\emacs\home\.emacs.d\elpa\racket-mode-20200924.1506\racket\syntax.rkt:89.18
I'm not sure if this is a bug or a setup issue. FWIW, I'm setting up
racket-mode in my .emacs file as follows:
(use-package racket-mode)
(add-to-list 'auto-mode-alist '("\\.rkt\\'" . racket-mode))
(require 'racket-xp)
(add-hook 'racket-mode-hook #'racket-xp-mode)
(add-hook 'racket-xp-mode-hook
(lambda ()
(remove-hook 'pre-redisplay-functions
#'racket-xp-pre-redisplay
t)))
Has anyone had any luck getting these two things to play nice?
