vim-racket interacts poorly with syntastic

[ezyang]

(Don't know if I should file a bug at syntastic instead.) When I have both syntastic and vim-racket in my bundle directory (vanilla install, no extra .vimrc configuration besides pathogen infect), running ':w' on even a small Racket file, e.g.

#lang racket
(require redex)

results in vim hanging for a few seconds. I don't really know how you'd go about debugging this, but removing either syntastic or vim-racket resolves the problem.

@ezyang Did you ever find a satisfactory solution to this? I just hit upon the same behavior, did some rudimentary debugging and narrowed it down to having let g:syntastic_enable_racket_racket_checker = 1 in my .vimrc.

Whatever Racket file is being edited, writing (:w) causes it to be executed - side effects and all 😱

Demo:

$ cat foo.rkt
#lang racket

(display-to-file "bar" "foo")

$ cat foo
cat: foo: No such file or directory

$ vim -c 'wq' foo.rkt

$ cat foo
bar

I noticed the behavior when editing a file with an infinite loop ... :)

I set it to 0 in the meantime, BTW.

Yep, known issue with syntastic: vim-syntastic/syntastic#1773
