Halt does not terminate jq

[smac89]

Describe the bug
From the v1.6 jq docs, it says that halt does the following:

Stops the jq program with no further outputs. jq will exit with exit status 0

However, from my testing of both halt and halt_error, neither of them causes jq to terminate with no further outputs.

To Reproduce
Input:

{"value":{"error":"no such element","message":"no such element: xxx"}}
{"value":null}

Command:

jq '.value | if .error then "\(.message)\n" | halt_error(1) else "" end'

Output:

no such element: xxx
""

Expected behavior
There should only be one output, seeing as after reading the first object, it causes halt_error to run

Environment (please complete the following information):

Distributor ID: Ubuntu
Description:    Ubuntu 21.10
Release:        21.10
Codename:       impish

• jq version 1.6

Additional context

[smac89]

Just as I posted this, I found a solution here. However, I think the docs need to be expanded on those two functions (halt, and halt_error) to explain that they only work when jq is run with -n.

@smac89 - The issue you raise could be regarded entirely as a documentation issue. Indeed, the jq developers have generally been quite definite about not wanting to break the stream-processing character of jq - i.e., assuming that input has not been "slurped", and that each input is well-formed, each input is processed separately.
