Original purpose

The library was built awaiting a jq module/package system, but also to collect shell utils for JSON manipulation. Some of these utils can be converted to packages, while others rely on external programs such as the bash shell.

Dependencies

Most utils were written for jq v1.4, and some can be probably be significantly improved with v1.5+ features. When the time comes, the plan is to maintain a branch per jq version for backwards compatibility.

jq-hopkok's runtime dependencies:

• jq v1.4+
• bash v4+

Some utils also use:

• GNU parallel

See also

• jqnpm for jq modules/packages.
• The jq wiki's cookbook for examples and smart solutions.
• har-dulcify for the origin of some utils, as well as example usage -- especially of the parallelism utils.
• ep-erroneous-votes for the origin of some utils, and example usage.

TODO

Patches/pull requests welcome!

• Write tests.
• Break out jq scripts from shell scripts.
• Split up files into smaller parts.
