Hi All,

Is there a way to see the result of the annotation made by errortrace?

(I think I missing something obvious).

Re: [racket-users] Re: Boot To Racket

2017-07-09 Thread John Berry
I've had a wish recently to try and turn Heresy into something like this,
with an RPi booting straight to a Heresy shell+editor interface akin to old
8-bit computers, complete with some kind of custom framebuffer 80-column
display (as I have an RPi1 and Xorg is hella slow).
It could all still be Linux underneath, but probably just sandboxed and
with the env. booting straight to it.
Sadly I've not got round to really working on that part yet.

I don't think there's a simple way, but if you want to see a single
module, then you can try replacing

 #lang 

with

 #lang errortrace 

and then use `raco expand`.

Works fine for my purpose.
