(For some reason the mail I sent to users<at>racket-lang.org last week never
made it to the Google Group, so I'm posting directly...)
I'm a 2nd year PhD student working with Shriram Krishnamurthi on improving
Redex's testing/checking performance and capabilities.
I was looking to use LambdaJS (http://cs.brown.edu/research/plt/dl/jssem/v1/)
as a case study, but unfortunately jscore.ss does not compile under the latest
version of Redex.
The shortcut used in the eval reduction relation
[(--> (σ (in-hole E e_1)) (σ (in-hole E e_2)))
(==> e_1 e_2)]))
now throws an error "reduction-relation: shortcut name may not be a
non-terminal in: e_1."
I believe this was caused by the following change
changed shortcuts in --> so that non-terminals are no
longer allowed for the names in the shortcut "parameters"
These shortcut names were never constrained to actually be
non-terminals, so this change is intended entirely to be
able to give a helpful error message in an attempt to avoid
As a Redex novice, I'm failing to avoid confusion in this case. Any advice on a
simple way to change the shortcut / reduction relation to respect this change
in Redex is greatly appreciated.
Thanks for the help!
