guntagger

based and expanded upon Labelmaker by Jesse Gibson aka PsychoLama

Organize your data by tags

guntagger is made for gunDB

What it is

If you need to organize your data with tags/labels this might be usefull. guntagger enables you to tag and untag nodes to custom tags/labels

Note: you cannot tag primitives. For that, use .key.

How to use it

Node.js

npm install guntagger

to install it, then you can require it from your app:

var guntagger = require('./lib/guntagger')

guntagger works with gun version 0.3, and makes use of the chaining system provided by Gun

var Gun = require('gun')
guntagger(Gun)
// You now have tag support!

Browser

For the browser, it's much simpler, since your version of gun is exported as a global. Just include it as a script tag, and labelmaker takes care of the rest.

<script src="node_modules/guntagger/guntagger.min.js"></script>
<!-- all done! -->

or install only the browser version with Bower

bower install guntagger

and then

<script src="bower_components/guntagger/guntagger.min.js"></script>

Yeah Polymer

I like Polymer and so guntagger also comes as a polymer element. You do need the polymer element for gun also ....have to publish that first...dangit

API

Three methods are exposed for your gun instances:

• .tag
• .untag
• .tagged

gun.tag(name[, name...])

You can pass .tag multiple names to index a node under. When called, it will try to read out your current context, index it under each tag, and then place each tag under a master list of every tag ever used. @tag can be a list ('one','two','three',...)
an Array (['one','two','three']) or a single String ('one')

gun.put({
  name: 'Bob',
  profession: 'developer'
}).tag(
  'members',
  'javascript developers',
  'gunDB developers',
  'examples'
)

gun.untag(name[, name...])

You can pass .untag multiple names to untag a node. When called, it will try to read out your current context, and untag each tag. @untag can be a list ('one','two','three',...)
an Array (['one','two','three']) or a single String ('one')

gun.get(<key>).untag(
  'members',
  'javascript developers')

gun.tagged()

When no arguments are provided you get the full tag list

gun.tagged().val(cb)

gun.tagged(,cb)

Provide a tagname and a callback to get all valid members of that tag. The callback will also return all tags for that tagmember

gun.tagged('gunDb').val(function(tagmember,tags){
    console.log(tagmember,tags)
})

gun.tagged(,cb,showUntagged)

@showUntagged Boolean returns also the members who where tagged to this tag before

gun.tagged('gunDb').val(function(tagmember,tags){
    console.log(tagmember,tags)
},true)
