This patch removes the weird behaviour of jv_invalid_with_msg(jv_null())
that returns jv_invalid() (i.e. empty), instead of a boxed jv_null().
The previous behaviour of null|error was obviously unintentional, and
allowing is jv_invalid_with_msg() to return values on which you can't
call jv_invalid_get_msg() is only error prone.
This patch exports all the binary operator builtins functions from
builtin.c and uses them for constant folding in the parser, allowing
constant folding to work will all kinds and combinations of constants.
Now string*number, $ARGS+$ARGS, string/string, etc will also be
constant folded and the implementation of constant folded operators and
runtime operators will be the same.
And thanks to the new ERRORK bytecode operation, errors are constant
folded too! (e.g. 1 / 0 [] * {} etc)
Use a StringStart component that is either FORMAT QQSTRING_START or
QQSTRING_START instead of having two similar rules for String.
This is simpler and avoids having to use an untyped mid-rule action
component to copy FORMAT at the top of the stack before QQString, and
having to use jv_free($<literal>3) instead of jv_free($1) just to make
bison not complain about the "unused" mid-rule component.
For some reason, the env vars are set correctly without refering the variable in `matrix` case-sensitvely:

For clarify, we update them to match the definitions. Besides, `CXX` is
not needed and removed.
Previously constant folding of zero division (e.x. 1/0) produces a
compile error. This was incorrectly implemented by checking if the
division result is infinite, so produces wrong results compared to the
query where no constant folding is processed (e.x. 1e308/0.1). This
patch delays the operation when the divisor is zero. This makes the
results more consistent, but changes the exit code on zero division from
3 to 5. Also 0/0 now produces the zero division error, not NaN.
This patch also fixes the modulo operation. Previously constant folding
logic does not take care of the % operator, but now it folds if the both
dividend and divisor are safe numbers to cast to the integer type, and
the divisor is not zero. This patch also fixes some code that relies on
undefined cast behaviors in C. The modulo operation produces NaN if
either the dividend or divisor is NaN.
You only need to specify the return type in a function pointer
declaration in C.
If you use () in the declaration, the function pointer can be called
with any arguments, and the type of the arguments is decided for each
function call based on the types of the arguments used for the call.
(To declare a function pointer for a function with no arguments, you use
`(void)'.)
Since all the cfunction structs have a fptr that points to a functions
that return jv, not void, we can we can just declare cfunction.fptr as
jv (*)() and avoid having those annoying and technically not C-standard
compliant casts everywhere.
* Bump up Bootstrap to v5.3.1, Bootstrap Icon to v1.10.5.
* Use autoComplete.js to drop dependency on jQuery and typeahead.js.
* Support dark mode.
* New svg logo and icon with responsive color mode support.
* Normalize section ids to lower kebab-case for easiness of linking.
* Use relative paths for links for local development (--root /output).
* Various markup cleanups and accessibility improvements.
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.
RS should only only have special meaning when parsing json-seq.
Before this fix, RS was sometimes treated as a value terminator, causing
weird results.
