go-crossplane

An unofficial Go port of the NGINX config/JSON converter crossplane.

Parse

This is an example that takes a path to an NGINX config file, converts it to JSON, and prints the result to stdout.

package main

import (
    "encoding/json"
    "fmt"
    "os"

    "github.com/aluttik/go-crossplane"
)

func main() {
    path := os.Args[1]

    payload, err := crossplane.Parse(path, &crossplane.ParseOptions{})
    if err != nil {
        panic(err)
    }

    b, err := json.Marshal(payload)
    if err != nil {
        panic(err)
    }

    fmt.Println(string(b))
}

Build

This is an example that takes a path to a JSON file, converts it to an NGINX config, and prints the result to stdout.

package main

import (
    "bytes"
    "encoding/json"
    "fmt"
    "io/ioutil"
    "os"

    "github.com/aluttik/go-crossplane"
)

func main() {
    path := os.Args[1]

    file, err := os.Open(path)
    if err != nil {
        panic(err)
    }

    content, err := ioutil.ReadAll(file)
    if err != nil {
        panic(err)
    }

    var payload crossplane.Payload
    if err = json.Unmarshal(content, &payload); err != nil {
        panic(err)
    }

    var buf bytes.Buffer
    if err = crossplane.Build(&buf, payload.Config[0], &crossplane.BuildOptions{}); err != nil {
        panic(err)
    }

    fmt.Println(buf.String())
}
