JV_PRINT_COLOUR was part of the public libjq headers and was removed as
part of 2d05b54. While JV_PRINT_COLOR is definitely the preferred
spelling this side of the pond, we shouldn't just remove otherwise
exposed enum values.
Attempting to use the existing FORK_OPT opcode resulted in difficulty
knowing when to pop an error message off the stack and when not to. This
commit makes DESTRUCTURE_ALT a real opcode that is identical to
FORK_OPT, except for never pushing the error message onto the stack when
continuing from an error backtrack.
Some small changes were necessary to the DUP/POP behavior surrounding
destructuring to accomodate this.
Not all stdio implementations disallow one to open a directory with
fopen(3) and so we specifically check for directories as it is also
in the standard search path.
This reverts commit e24af3c78e.
While the semantics are desirable, there is no way to implement them
efficiently. The reason is that in order to handle backtracking (empty)
from the state update expression, we have to retain a reference to the
reduction state value in order to restore it upon backtracking.
Retaining a reference to the reduction state kills performance by
causing lots of additional memory allocations and garbage because the
input to the update expression will always have at least two references,
thus no changes to it can be done in-place, and all changes end up being
CoW changes.
Avoiding this is the very reason for the LOADVN instruction (leaving
`null` in the variable loaded from).
This has been a complicated issue to fix for a number of reasons.
The core of it is that the behavior is different between different
versions of macOS, some of which set possible-but-incorrect values.
This commit addresses the issue by always using our computation for
tm_wday and tm_yday on macOS. As a side-effect, strptime format
strings that specify %u and %j will no longer work on macOS.
As noted by @nicowilliams, `tostream` used `keys`,
which sorts the keys in alphabetical order, instead
of `keys_unsorted`, which preserves the parsing order.
Fixes#1541.
strptime() on OS X and *BSDs (reputedly) does not set tm_wday and
tm_yday unless corresponding %U and %j format specifiers were used.
That can be... surprising when one parsed year, month, and day anyways.
Glibc's strptime() conveniently sets tm_wday and tm_yday in those cases,
but OS X's does not, ignoring them completely.
This commit makes jq compute those where possible, though the day of
week computation may be wrong for dates before 1900-03-01 or after
2099-12-31.
OS X (and *BSD) strptime() does not set tm_wday nor tm_yday unless
corresponding format options are used. That means we must call timegm()
to set them.
The conditional expression in if-then-elif-else-end cannot contribute to
path expressions because it doesn't change the input to any of the then/
elif/else expressions. These must be generated via gen_subexp().
See also #1366.
It needs to be possible to do something like
getpath($paths[]) += 1
meaning: increment all the paths in . that are listed in $paths[].
In order to do this getpath() needs to update the jq->path and
jq->value_at_path as necessary.
