<p>I am looking for code that can parse json metadata to create Go structs which can in turn be used to extract data from the network. Anyone have links to one?</p>

Hadn't seen that before. Very handy.</p></pre>DeedleFake: <pre><p>That's a neat one. Unfortunately, it doesn't seem to handle everything properly. Try this one: <code>[{"id": "test", "value": 3}, {"id": "second", "value": "This is another test."}]</code></p></pre>mwholt: <pre><p>It's a <a href="https://github.com/mholt/json-to-go/issues/6" rel="nofollow">known issue</a> when an array does not contain consistently-typed values.</p>
<p>Pull requests welcome.</p></pre>itsmontoya: <pre><p>If your value types are changing for the same keys, I would re-evaluate the values you are storing. </p></pre>DeedleFake: <pre><p>You may not have a choice. What if you're dealing with someone else's API?</p>
<p>Either way, though, <code>encoding/json</code> can handle <a href="https://play.golang.org/p/GOv_08OMAJ" rel="nofollow">this particular case</a> just fine.</p>

<p>Disclaimer: I'm the author of that website.</p></pre>dharanimo: <pre><p>The jsontuils seems a good starting point. I might have to do changes to what is there. Here is my problem. We express metadata of our data model in json. Here is a simple example:</p>
<pre><code>{
"name": "Resource",
"pluralName": "Resources",
"parent": "Base",
"description": "This is the parent class of all resources with some default attributes defined",
"fields": {
"healthState": {
"mandatory": true,
"description": "",
"dataType": "enumeration",
"enumValues": [ "healthy", "error", "probation", "maintenance", "unknown"],
"defaultValue" : "unknown"
},
"policyGroups" : {
"description": "The policy group associated with this resource",
"dataType": "relationship",
"relationType": "Reference",
"refDataType": "PolicyGroup",
"cardinality": "Many"
}
}
}
</code></pre>
<p>I would like the mapping to be</p>
<pre><code>// Comments from description
type Resource struct {
Base
// Comments from description
healthState string
//My comment: All references become strings which has the id of the object
policyGroups [] string
}
</code></pre>
<p>The above mapping would be super useful for me to extract instances of resource coming on the wire from http calls. Does my problem makes sense? Is there a better way to do it?</p></pre>tclineks: <pre><p>$ go get <a href="https://github.com/tmc/json-to-struct" rel="nofollow">github.com/tmc/json-to-struct</a></p></pre>omginternets: <pre><p>I hate to be that guy, but <a href="http://lmgtfy.com/?q=json+to+go+struct+parser" rel="nofollow">come on</a>...</p></pre>dharanimo: <pre><p>Hmm..
