Previously, the @uri example didn't match the actual behavior of the current jq, as exclamation marks do not need to be encoded in URIs. Replace the example with an input that needs encoding, and is encoded by jq.
jq
jq is a command-line JSON processor.
If you want to learn to use jq, read the documentation at http://stedolan.github.io/jq. This documentation is generated from the docs/ folder of this repository.
If you want to hack on jq, feel free, but be warned that its internals are not well-documented at the moment. Bring a hard hat and a shovel. Also, read the wiki: http://github.com/stedolan/jq/wiki
If you're building directly from the latest git, you'll need flex and bison installed. To build, run:
autoreconf -i
./configure
make
After make finishes, you'll be able to use ./jq. You can also
install it using:
sudo make install
If you're not using the latest git version but instead building a
released tarball (available on the website), then you won't need to
run autoreconf (and shouldn't), and you won't need flex or bison.
