This adds `input_filename` and `input_line_number` built-in functions
for use in, for example, `error` messages.
Example:
$ printf '{"a":1}\n{"a":2}\n' > 4.json
$ printf '{"a":"hello"}\n' > 5.json
$ ./jq '{ "file":input_filename, "line":input_line_number, "value":.a }' 4.json 5.json
{
"file": "4.json",
"line": 1,
"value": 1
}
{
"file": "4.json",
"line": 2,
"value": 2
}
{
"file": "5.json",
"line": 1,
"value": "hello"
}
Documentation
The jq website, manpages and some of the tests are generated from this
directory. The directory holds a Bonsai
website, and the manual is a YAML file in content/3.manual.
To build the documentation (including building the jq manpage), you'll need a working Ruby setup. The easiest way to get one is to install RVM and Ruby 1.9.3 like so:
\curl -L https://get.rvm.io | bash -s stable --ruby=1.9.3
After that finishes installing, you'll need to make sure RVM is on
your path by doing source $HOME/.rvm/scripts/rvm, or just opening a
new shell. See http://rvm.io for more info on RVM.
Once RVM is installed, you can install all the dependencies for jq's
documentation build by running this from the docs directory:
bundle install
When bundle manages to install the dependencies, rerun ./configure
in the jq root directory and then the Makefile will be able to
generate the jq manpage.
