jq() paste bare numbers together

[mgirlich]

The following code returns "12" instead of "1" and "2" separately

as.character(jqr::jq(c("1", "2")))
#> [1] "12"
# expected
# [1] "1" "2"

thanks for this @mgirlich

jq expects JSON as the input as the documentation states, so this works as expected i think

jq(jsonlite::toJSON(c("1", "2")))
#> [
#>     "1",
#>     "2"
#> ]

[mgirlich]

bare numbers are also valid json (see standard and try out at jsonlint). My workflow is something like in the following code

x <- jqr::jq(c('{"a": 1}', '{"a": 2}'), '.a')
x
#> [
#>     1,
#>     2
#> ]
jqr::jq(x)
#> 12

@jeroen any thoughts on this issue. seems that it shouldn't combine the numbers together

echo '"1" "2"' | jq .
# "1"
# "2"

[sckott]

@mgirlich Sorry about the delay. We have limited bandwidth to work on this. Fastest way is if you have submit a PR with a fix/change

Hello,

I encountered a similar strange behavior with arrays of numbers:

> vv
[
    102,
    123
]
> kk
[
    "2019-01-01T00:00:14",
    "2019-01-01T00:01:15"
]
> paste0(kk) # ok
[1] "[\"2019-01-01T00:00:14\",\"2019-01-01T00:01:15\"]"
> paste0(vv) # weird
[1] "102" "123"
> vv %>% tostring() # very weird
"102123"
> kk %>% tostring() # ok
"[\"2019-01-01T00:00:14\",\"2019-01-01T00:01:15\"]"

[sckott]

thanks @stla but the above eg is not reproducible. what are vv and kk in reproducible code

[stla]

Ah yes, sorry.

str <- '{"2019-01-01T00:00:14":102,"2019-01-01T00:01:15":123}'
kk <- str %>% keys()
vv <- str %>% index()

[sckott]

that is weird. if you do it all in one go it turns out as expected i think:

str <- '{"2019-01-01T00:00:14":102,"2019-01-01T00:01:15":123}'
w <- str %>% index() %>% tostring()
w
#> [
#>     "102",
#>     "123"
#> ]

can you do it that way?
