I am interested in reading a schemas(json formatted text file) and unmarshall it as schemas (for which i have some JSON structures defined in a .GO file) and For each type of structure in the Schema, I want to generate a corresponding .go file which has the code for performing CRUD operations using the template package (http://golang.org/pkg/text/template/) to generate these files.
Example of a structure in a schema file - {
type struct XYZ {
Type string `json:"type,omitempty"`
ResourceType string `json:"resourceType,omitempty"`
Links map[string]string `json:"links,omitempty"`
}
The text file has a JSON structured data which is something of this form -
{
"type": "collection",
"resourceType": "schema",
"links": {
"self": "…/v1/schemas",
},
"createTypes": { },
"actions": { },
"data": [ 86 items
{
"id": "schema",
"type": "schema",
"links": {
"self": "/schemas/schema",
"collection": "…/schemas",
},
...
}
}
Could somebody help me how could i possibly generate the code for these CRUD operations for different structs using the GO template package.
You might find go generate useful.
New go tool subcommand proposed for Go 1.4. Please see the design document and comment in this thread.

Introduction
The go build command automates the construction of Go programs but sometimes preliminary processing is required, processing that go build does not support. Motivating examples include:
- yacc: generating .go files from yacc grammar (.y) files
- protobufs: generating .pb.go files from protocol buffer definition (.proto) files
- Unicode: generating tables from UnicodeData.txt
- HTML: embedding .html files into Go source code
- bindata: translating binary files such as JPEGs into byte arrays in Go source
There are other processing steps one can imagine:
- string methods: generating String() string methods for types used as enumerated constants
- macros: generating customized implementations given generalized packages, such as sort.Ints from ints
This proposal offers a design for smooth automation of such processing.
