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: tool_fs_cat.go
    path of file: ./repos/bud/internal/cli
    
    the code of the file until where you have to start completion: package cli

import (
	"context"
	"fmt"
	"io/fs"
	"path"
	"path/filepath"

	"github.com/livebud/bud/framework"
	"github.com/livebud/bud/package/virtual"
)

type ToolFsCat struct {
	Flag *framework.Flag
	Path string
}

func (c *CLI) ToolFsCat(ctx context.Context, in *ToolFsCat) error {
	
    
func (c *CLI) ToolFsCat(ctx context.Context, in *ToolFsCat) error {
	// Generate bud files
	generate := &Generate{Flag: in.Flag}
	if err := c.Generate(ctx, generate); err != nil {
		return err
	}
	abs, err := filepath.Abs(c.Dir)
	if err != nil {
		return err
	}
	fsys := virtual.OS(abs)

	// Read the file out
	code, err := fs.ReadFile(fsys, path.Clean(in.Path))
	if err != nil {
		return err
	}

	// Print it out
	fmt.Fprintln(c.Stdout, string(code))
	return nil
}
