n.b.: { $__loc__: "foo" } is still not allowed.
$__loc__ cannot be overwritten, and it is always an object.
Using { $x: "foo" } where $x is not a string is an error, so there is
not much of a point in supporting that.
Previously, bindings were parsed as the combination of two tokens:
'$' IDENT
This meant that using a keyword as variable name (e.g. $then, $label)
did not work.
Attempts were made to allow $keyword to work by adding some '$' Keyword
rules in the parser, but this did not allow $keyword in all places:
jq --arg label foo -n '$label' # ok
jq -n '"foo" as $label | .' # error
Treating $foo as a single token is much simpler, in my opinion.
This patch also changes how LOC is lexed: "$__loc__" instead of as
"__loc__" that gets combined with '$' in the parser.
This patch also disallows having spaces after '$' when recalling a
variable `$ foo' since that was probably just an unintentional side
effect of the implementation, and it was not documented.
Fixes#2675
The primary purpose of this commit is to rectify most problems with
`gsub` (and also `sub` with the `g` option), in particular fix#1425 ('\b'),
fix#2354 (lookahead), and fix#2532 (regex == `"^(?!cd ).*$|^cd "`).
This commit also partly resolves#2148 and resolves#1206 in that
`gsub` no longer loops infinitely; however, because the new `gsub`
depends critically on `match/2`, the behavior when regex == `""` is
sometimes non-standard.
The documentation has been updated to reflect the fact that `sub`
and `gsub` are intended to be regular in the second argument.
Also, `_nwise/1` has been tweaked to take advantage of TCO.
* Release pipeline
* Group CI builds for different OSes into `ci.yml`.
* Add release job to release `jq` when tag is in the format of v*.
* Use `clang` as the only compiler on CI.
* Provide extensible matrix for future cross-compile builds, e.g.
for https://github.com/jqlang/jq/pull/2618.
* Locate bison for Windows build
* Also install flex for Windows build
* Add matrix to test all available GH Actions images
* Enable all tests for Windows
* Run `brew update-reset` when `brew update` fails
`brew update` can fail for "Error: Fetching /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask failed!"

* Select gcc binaries to release
* Only enable CI when push to master & tag
* Try out statick build
* No need to enforce the same `AM_INIT_AUTOMAKE` version for MacOS
* Disable static build for ubuntu-20.04
