A fast command-line utility for dealing with JSON
json-quick provides one fast, easy-to-use command for dealing with JSON
on the command line.
Currently, json-quick must be cloned via Git and compiled from source.
See the project README
for more detailed instructions.
json-quick’s features are separated into a number of commands. Currently,
the following commands are available:
help - Displays usage and version information.prettify - Pretty-prints any JSON given as input.select - Selects a subset of JSON given as input.verify - Verifies that and JSON given as input is
specification-conformant.These options are available for any command:
--in <file>, -i <file>: Reads input from <file> instead of stdin.--out <file>, -o <file>: Writes output to <file> instead of
stdout.Displays general and command-specific usage and version information.
Options:
--with <command>, -w <command>: Displays usage information for
<command>.Pretty-prints any JSON given as input. Currently, this command always indents with two spaces. However, options to customize indentation will be available in the future.
Selects a subset of the JSON that is given as input. Uses selection syntax for patterns.
Options:
--pattern <pattern>, -p <pattern>: Selects using <pattern>. If no
pattern is specified, the entire JSON object is selected.Ensures that its input is valid JSON (conformant to the official specification). Returns with a zero exit code and prints “Valid JSON” to output if the JSON is valid. Returns with a non-zero exit code and prints an error to stderr if the JSON is not valid.
To select part of a JSON object, you can use dot-separated parts. Each part can be a double-quoted property name, a non-quoted property name, or an asterisk, which matches all property names.
For example, the syntax my_property."a.key".0" would select an object’s
my_property property, then the a.key property of that object, and finally
the first element of that array.
