Unhandled exception #72

Closed SymbolixAU closed 3 years ago

SymbolixAU commented 6 years ago

The code I've written is almost certainly not valid, but, I'm pointing out this issue as it may be something to resolve at the C level to prevent a crash?

While playing about with this SO question I wrote the following which crashes my R / RStudio

library(jqr)
js1 <- '{"value": ["1","2","3"]}'
js2 <- '{"value": ["4","5","6"]}'
js <- paste(js1, js2)
jqr::jq(js, '[inputs]')

not sure why that fails. it does seem to be in the jq documentation.

jeroen commented 6 years ago

What is the expected output of this jq program?

SymbolixAU commented 6 years ago

I've no idea. I was just messing about with commands to see what they did.

sckott commented 5 years ago

seems inputs is usually used along with the -n flag https://github.com/stedolan/jq/wiki/FAQ - not sure what to do about this though
