jq: update to 1.7.
# 1.7
Since the last stable release many things have happened:
- jq now lives at <https://github.com/jqlang>
Full commit log can be found at \
<https://github.com/jqlang/jq/compare/jq-1.6...jq-1.7> but here are some \
highlights:
## CLI changes
- Make object key color configurable using `JQ_COLORS` environment variable. \
@itchyny @haguenau @ericpruitt #2703
```sh
# this would make "field" bold yellow (`1;33`, the last value)
$ JQ_COLORS="0;90:0;37:0;37:0;37:0;32:1;37:1;37:1;33" ./jq -n \
'{field: 123}'
{
"field": 123
}
```
- Change the default color of null to Bright Black. @itchyny #2824
- Respect `NO_COLOR` environment variable to disable color output. See \
<https://no-color.org> for details. @itchyny #2728
- Improved `--help` output. Now mentions all options and nicer order. @itchyny \
@wader #2747 #2766 #2799
- Fix multiple issues of exit code using `--exit-code`/`-e` option. @ryo1kato #1697
```sh
# true-ish last output value exits with zero
$ jq -ne true ; echo $?
true
0
# false-ish last output value (false and null) exits with 1
$ jq -ne false ; echo $?
false
1
# no output value exists with 4
$ jq -ne empty ; echo $?
4
```
- Add `--binary`/`-b` on Windows for binary output. To get `\n` instead of \
`\r\n` line endings. @nicowilliams 0dab2b1
- Add `--raw-output0` for NUL (zero byte) separated output. @asottile @pabs3 \
@itchyny #1990 #2235 #2684
```sh
# will output a zero byte after each output
$ jq -n --raw-output0 '1,2,3' | xxd
00000000: 3100 3200 3300 1.2.3.
# can be used with xargs -0
$ jq -n --raw-output0 '"a","b","c"' | xargs -0 -n1
a
b
c
$ jq -n --raw-output0 '"a b c", "d\ne\nf"' | xargs -0 \
printf '[%s]\n'
[a b c]
[d
e
f]
# can be used with read -d ''
$ while IFS= read -r -d '' json; do
> jq '.name' <<< "$json"
> done < <(jq -n --raw-output0 '{name:"a b \
c"},{name:"d\ne\nf"}')
"a b c"
"d\ne\nf"
# also it's an error to output a string containing a NUL when using NUL separator
$ jq -n --raw-output0 '"\u0000"'
jq: error (at <unknown>): Cannot dump a string containing NUL with \
--raw-output0 option
```
- Fix assert crash and validate JSON for `--jsonarg`. @wader #2658
- Remove deprecated `--argfile` option. @itchyny #2768
- Enable stack protection. @nicowilliams #2801
## Language changes
- Use decimal number literals to preserve precision. Comparison operations \
respects precision but arithmetic operations might truncate. @leonid-s-usov \
#1752
```sh
# precision is preserved
$ echo '100000000000000000' | jq .
100000000000000000
# comparison respects precision (this is false in JavaScript)
$ jq -n '100000000000000000 < 100000000000000001'
true
# sort/0 works
$ jq -n -c '[100000000000000001, 100000000000000003, 100000000000000004, \
100000000000000002] | sort'
[100000000000000001,100000000000000002,100000000000000003,100000000000000004]
# arithmetic operations might truncate (same as JavaScript)
$ jq -n '100000000000000000 + 10'
100000000000000020
```
- Adds new builtin `pick(stream)` to emit a projection of the input object or \
array. @pkoppstein #2656 #2779
```sh
$ jq -n '{"a": 1, "b": {"c": 2, "d": \
3}, "e": 4} | pick(.a, .b.c, .x)'
{
"a": 1,
"b": {
"c": 2
},
"x": null
}
```
- Adds new builtin `debug(msgs)` that works like `debug` but applies a filter on \
the input before writing to stderr. @pkoppstein #2710
```sh
$ jq -n '1 as $x | 2 | debug("Entering function foo with $x == \
\($x)", .) | (.+1)'
["DEBUG:","Entering function foo with $x == 1"]
["DEBUG:",2]
3
$ jq -n '{a: 1, b: 2, c: 3} | debug({a, b, sum: (.a+.b)})'
["DEBUG:",{"a":1,"b":2,"sum":3}]
{
"a": 1,
"b": 2,
"c": 3
}
```
- Adds new builtin `scan($re; $flags)`. Was documented but not implemented. \
@itchyny #1961
```sh
# look for pattern "ab" in "abAB" ignoring casing
$ jq -n '"abAB" | scan("ab"; "i")'
"ab"
"AB"
```
- Adds new builtin `abs` to get absolute value. This potentially allows the \
literal value of numbers to be preserved as `length` and `fabs` convert to \
float. @pkoppstein #2767
- Allow `if` without `else`-branch. When skipped the `else`-branch will be `.` \
(identity). @chancez @wader #1825 #2481
```sh
# convert 1 to "one" otherwise keep as is
$ jq -n '1,2 | if . == 1 then "one" end'
"one"
2
# behaves the same as
$ jq -n '1,2 | if . == 1 then "one" else . end'
"one"
2
# also works with elif
$ jq -n '1,2,3 | if . == 1 then "one" elif . == 2 then \
"two" end
"one"
"two"
3
```
- Allow use of `$binding` as key in object literals. @nicowilliams 8ea4a55
```sh
$ jq -n '"a" as $key | {$key: 123}'
{
"a": 123
}
# previously parentheses were needed
$ jq -n '"a" as $key | {($key): 123}'
{
"a": 123
}
```
- Allow dot between chained indexes when using `.["index"]` \
@nicowilliams #1168
```sh
$ jq -n '{"a": {"b": 123}} | .a["b"]'
123
# now this also works
$ jq -n '{"a": {"b": 123}} | .a.["b"]'
123
```
- Allow dot for chained value iterator `.[]`, `.[]?` @wader #2650
```sh
$ jq -n '{"a": [123]} | .a[]'
123
# now this also works
$ jq -n '{"a": [123]} | .a.[]'
123
```
- Fix try/catch catches more than it should. @nicowilliams #2750
- Speed up and refactor some builtins, also remove `scalars_or_empty/0`. \
@muhmuhten #1845
- Now `halt` and `halt_error` exit immediately instead of continuing to the next \
input. @emanuele6 #2667
- Fix issue converting string to number after previous convert error. @thalman #2400
- Fix issue representing large numbers on some platforms causing invalid JSON \
output. @itchyny #2661
- Fix deletion using assigning empty against arrays. @itchyny #2133
```sh
# now this works as expected, filter out all values over 2 by assigning empty
$ jq -c '(.[] | select(. >= 2)) |= empty' <<< '[1,5,3,0,7]'
[1,0]
```
- Allow keywords to be used as binding name in more places. @emanuele6 #2681
- Allow using `nan` as NaN in JSON. @emanuele6 #2712
- Expose a module's function names in `modulemeta`. @mrwilson #2837
- Fix `contains/1` to handle strings with NUL. @nicowilliams 61cd6db
- Fix `stderr/0` to output raw text without any decoration. @itchyny #2751
- Fix `nth/2` to emit empty on index out of range. @itchyny #2674
- Fix `implode` to not assert and instead replace invalid unicode codepoints. \
@wader #2646
- Fix `indices/1` and `rindex/1` in case of overlapping matches in strings. \
@emanuele6 #2718
- Fix `sub/3` to resolve issues involving global search-and-replace (gsub) \
operations. @pkoppstein #2641
- Fix `significand/0`, `gamma/0` and `drem/2` to be available on macOS. @itchyny \
#2756 #2775
- Fix empty regular expression matches. @itchyny #2677
- Fix overflow exception of the modulo operator. @itchyny #2629
- Fix string multiplication by 0 (and less than 1) to emit empty string. \
@itchyny #2142
- Fix segfault when using libjq and threads. @thalman #2546
- Fix constant folding of division and reminder with zero divisor. @itchyny #2797
- Fix `error/0`, `error/1` to throw null error. @emanuele6 #2823
- Simpler and faster `transpose`. @pkoppstein #2758
- Simple and efficient implementation of `walk/1`. @pkoppstein #2795
- Remove deprecated filters `leaf_paths`, `recurse_down`. @itchyny #2666

Log message:
jq: Update devel/jq to 1.6
pkgsrc changes:
- Use GITHUB_RELEASE instead of GITHUB_TAG because the former does not need
auto* tools (despite we need auto* tools for patches/, hopefully one day they
will be applied!)
- Remove no longer needed SUBST_*, `git describe' is no longer used
- Remove patch-src_jv__parse.c and patch-src_jv__print.c, they are
present in 1.6
- Rename and readjust patch-Makefile.in to patch-Makefile.am
(pre-configure target rewrote it due `autoreconf')
Changes:
1.6
---
New in this release since 1.5:
- Destructuring Alternation
- New Builtins:
* builtins/0
* stderr/0
* halt/0, halt_error/1
* isempty/1
* walk/1
* utf8bytelength/1
* localtime/0, strflocaltime/1
* SQL-style builtins
* and more!
- Add support for ASAN and UBSAN
- Make it easier to use jq with shebangs (8f6f28c)
- Add $ENV builtin variable to access environment
- Add JQ_COLORS env var for configuring the output colors
Bug fixes:
- Calling jq without a program argument now always assumes . for the program,
regardless of stdin/stdout. (5fe0536)
- Make sorting stable regardless of qsort. (7835a72)
- Adds a local oniguruma submodule and the
`./configure --with-oniguruma=builtin' option to make it easier to build
with oniguruma support on systems where you can't install system-level
libraries. (c6374b6 and 02bad4b)
- And much more!
