You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: alpaca.go
    path of file: ./repos/alpaca/alpaca
    
    the code of the file until where you have to start completion: package alpaca

import (
	"bitbucket.org/pkg/inflect"
	"fmt"
	"os"
	"path/filepath"
	"strings"
)

const (
	Version = "0.2.1"
)

var (
	LibraryRoot string
	FormatList  []string
)

type Data struct {
	Pkg PkgStruct
	Api ApiStruct
	Doc map[string]DocClass

	Fnc map[string]interface{}

	Version string    /* Alpaca version to be us
    
func WriteLibraries(opts *LanguageOptions) {
	data := ReadData()
	ModifyData(data)

	if !opts.Php {
		HandleError(CheckPhp(data))
		FunctionsPhp(data.Fnc)
		WritePhp(data)
	}

	if !opts.Python {
		HandleError(CheckPython(data))
		FunctionsPython(data.Fnc)
		WritePython(data)
	}

	if !opts.Ruby {
		HandleError(CheckRuby(data))
		FunctionsRuby(data.Fnc)
		WriteRuby(data)
	}

	if !opts.Node {
		HandleError(CheckNode(data))
		FunctionsNode(data.Fnc)
		WriteNode(data)
	}
}
