The option naming --nul-output was confusing, especially when we have a
similar option for input stream in the future (--nul-input vs --null-input).
Based on the observation of other command line tools, we rename the option
to --raw-output0. We also drop the short option -0 to avoid confusion on
introducing the NUL-delimited input option.
Unlike the other command line tools outputting file names with NUL delimiter,
jq deals with JSON, and its strings may contain NUL character. To protect
users from the risk of injection attacks, we abort the program and print an
error message before outputting strings including NUL character. Closes#2683.
* Set default error code to -4 in main(), Fixes#1142
* fix --exit-code with more than one object in input, Fixes#1139
- Return code 1 or 4 based on last output, not last input.
Rather than testing that a constant expression produces so many
instructions, test that a variety of of such expressions produce the
same number of instructions. This will make future changes in the
compiler less likely to break this test.
Allow a continuation on a comment immediately after a shebang to make
this traditional hack possible:
#!/bin/sh
# this next line is ignored by jq \
exec jq -f "$0" "$@"
# jq code follows
But continue only on the first line following a shebang, and only if
it's a comment.
