Changes for jq:
Update to version 1.7.1:
- Make the default background color more suitable for bright backgrounds.
- Allow passing the inline jq script after --.
- Fix possible uninitialised value dereference if jq_init() fails
- Simplify paths/0 and paths/1.
- Reject U+001F in string literals.
- Remove unused nref accumulator in block_bind_library.
- Remove a bunch of unused variables, and useless assignments.
- main.c: Remove unused EXIT_STATUS_EXACT option.
- Actually use the number correctly casted from double to int as index.
- src/builtin.c: remove unnecessary jv_copy-s in type_error/type_error2.
- Remove undefined behavior caught by LLVM 10 UBSAN.
- Convert decnum to binary64 (double) instead of decimal64. This makes jq behave like the JSON specification suggests and more similar to other languages.
- Fix memory leaks on invalid input for ltrimstr/1 and rtrimstr/1.
- Fix memory leak on failed get for setpath/2.
- Fix nan from json parsing also for nans with payload that start with 'n'.
- Allow carriage return characters in comments.
- Generate links in the man page.
- Add extern C for C++.
- Make object key color configurable using JQ_COLORS environment variable.
- Change the default color of null to Bright Black.
- Respect NO_COLOR environment variable to disable color output.
- Improved --help output. Now mentions all options and nicer order.
- Fix multiple issues of exit code using --exit-code/-e option.
- Add --raw-output0 for NUL (zero byte) separated output.
- Fix assert crash and validate JSON for --jsonarg.
- Remove deprecated --argfile option.
- Use decimal number literals to preserve precision. Comparison operations respects precision but arithmetic operations might truncate.
- Adds new builtin pick(stream) to emit a projection of the input object or array.
- Adds new builtin…
