jspect v0.0.8

jspect

installation

Install jspect globaly.

npm i jspect -g

Wat

jspect is an easy way to inspect JSON or .js files from the command line.

Usage

Log out a json file.

jspect ./package.json
// will log the whole file

Log out a property on a json file.

jspect ./package.json -p version
// -> 0.0.4

Log out a deeper property

jspect ./package.json -p dependencies.gedi
// -> 0.12.1

Run up a module and print its module.exports: (I'll use gedi-paths as an example)

jspect ./paths.js
// will log the whole exports

Log out a property on a module.

jspect ./paths.js -p is
// -> [Function]

Log out a deeper property

jspect ./paths.js -p constants.separator
// -> /

MOAR POWER!

jspect uses gedi to parse expressions, so you can do some pretty cool things like...

Run up the module, and get the keys on a property:

jspect ./paths.js -e "(keys [constants])"
// ->   [ 'separator',
//        'upALevel',
//        'currentKey',
//        'root',
//        'start',
//        'end',
//        'wildcard' ]

Filter the keys where the key starts with s:

jspect ./paths.js -e "(filter (keys [constants]) {key (== (slice 0 1 key) 's')})"
// ->   [ 'separator', 'start' ]

Filter the keys where the key starts with s and add their lengths:

jspect ./paths.js -e "(length (apply join (concat (array '') (filter (keys [constants]) {key (== (slice 0 1 key) 's')}))))"
// ->   14

But that would be silly..
