VCL parser written in Go

Usage

Decode

Let's say you have a VCL file.

acl purge_ip {
    "localhost";
    "127.0.0.1";
}

Define a go struct how you what to retrieve the VCL expressions and attributes.

type Root struct {
    ACLs []*ACL `vcl:"acl,block"`
}

type ACL struct {
    Type      string   `vcl:"type,label`
    Endpoints []string `vcl:",flat"`
}  

Then decode your like following.

var r Root
err := vcl.Decode(b, &r)
fmt.Println(r.ACLs[0].Type)
fmt.Println(r.ACLs[0].Endpoints)

$ go run main.go
=> "purge_ip"
=> []string{"localhost","127.0.0.1"}

Supported tags

I am not a VCL master so there may be not supported features.

There are struct tags you can use for you input.

• block: Represents a unit of your block like acl, sub, etc...
• label: The label of your block.
• flat: Represents a expression field
• comment: Get comments
• attr: (Default) Attribute of your block
