After a five year hiatus we're back with a GitHub organization, with new admins and new maintainers who have brought a great deal of energy to make a long-awaited and long-needed new release.
Since the last stable release many things have happened:
amd64, arm64, armel, armhf, i386, mips, mips64, mips64el, mips64r6, mips64r6el, mipsel, mipsr6, mipsr6el, powerpc, ppc64el, riscv64 and s390xamd64 and arm64i386 and amd64linux/386, linux/amd64, linux/arm64, linux/mips64le, linux/ppc64le, linux/riscv64 and linux/s390xghcr.io/jqlang/jq instead of docker hub. @itchyny #2652Full commit log can be found at https://github.com/jqlang/jq/compare/jq-1.6...jq-1.7 but here are some highlights:
Make object key color configurable using JQ_COLORS environment variable. @itchyny @haguenau @ericpruitt #2703
# this would make "field" yellow (33, the last value) $ JQ_COLORS="1;30:0;37:0;37:0;37:0;32:1;37:1;37:1;33" ./jq -n '{field: 123}' { "field": 123 }
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 #2747 #2766
Last output value can now control exit code using --exit-code/-e. @ryo1kato #1697
# 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. 0dab2b1 @nicowilliams
Add --raw-output0 for NUL (zero byte) separated output. @asottile @pabs3 @itchyny #1990 #2235 #2684
# 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 '%q\n' 'a b c' 'd'$'\n''e'$'\n''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
Use decimal number literals to preserve precision. Comparison operations respects precision but arithmetic operations might truncate. @leonid-s-usov #1752
# precision is preserved $ jq -n '100000000000000000' 100000000000000000 # comparison respects precision (this is false in JavaScript) $ jq -n '100000000000000000 < 100000000000000001' true # 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
$ 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
$ 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
# 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
# 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. 8ea4a55 @nicowilliams
$ 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
$ jq -n '{"a": {"b": 123}} | .a["b"]' 123 # now this works also $ jq -n '{"a": {"b": 123}} | .a.["b"]' 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
Make 0 divided by 0 result in NaN consistently. @itchyny #2253
Fix issue representing large numbers on some platforms causing invalid JSON output. @itchyny #2661
Fix deletion using assigning empty against arrays. @itchyny #2133
# 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]
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
Simpler and faster transpose. @pkoppstein #2758
Allow keywords to be used as binding name in more places. @emanuele6 #2681
Allow using nan as NaN in JSON. @emanuele6 #2712
Fix indices/1 and rindex/1 in case of overlapping matches in strings. @emanuele6 #2718
Enable significand/0, gamma/0 and drem/2 on macOS. @itchyny #2756 #2775
Fix segfault when using libjq and threads. @thalman #2546
Fix sub/3 to resolve issues involving global search-and-replace (gsub) operations. @pkoppstein #2641
