Log Message:
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
