Overview ¶
This class implements a reader that can extract the content of individual files inside a ZIP archive. See also ZIPPacker.
package main
import (
"path/filepath"
"strings"
"graphics.gd/classdb/DirAccess"
"graphics.gd/classdb/FileAccess"
"graphics.gd/classdb/ZIPReader"
)
func ReadZipFile() []byte {
var reader = ZIPReader.New()
var err = reader.Open("user://archive.zip")
if err != nil {
return nil
}
var res = reader.ReadFile("hello.txt")
reader.Close()
return res
}
// Extract all files from a ZIP archive, preserving the directories within.
// This acts like the "Extract all" functionality from most archive managers.
func ExtractAllFromZip() {
var reader = ZIPReader.New()
reader.Open("res://archive.zip")
// Destination directory for the extracted files (this folder must exist before extraction).
// Not all ZIP archives put everything in a single root folder,
// which means several files/folders may be created in `root_dir` after extraction.
var rootDir = DirAccess.Open("user://")
var files = reader.GetFiles()
for _, filePath := range files {
// If the current entry is a directory.
if strings.HasSuffix(filePath, "/") {
rootDir.MakeDirRecursive(filePath)
continue
}
// Write file contents, creating folders automatically when needed.
// Not all ZIP archives are strictly ordered, so we need to do this in case
// the file entry comes before the folder entry.
rootDir.MakeDirRecursive(filepath.Base(filepath.Join(rootDir.GetCurrentDir(), filePath)))
var file = FileAccess.Open(filepath.Join(rootDir.GetCurrentDir(), filePath), FileAccess.Write)
var buffer = reader.ReadFile(filePath)
file.StoreBuffer(buffer)
}
}

Types ¶
type Advanced ¶
type Advanced = class
Advanced exposes a 1:1 low-level instance of the class, undocumented, for those who know what they are doing.
type Extension ¶
Extension can be embedded in a new struct to create an extension of this class. T should be the type that is embedding this Extension
func (*Extension[T]) AsRefCounted ¶
func (self *Extension[T]) AsRefCounted() [1]gd.RefCounted
func (*Extension[T]) AsZIPReader ¶
type ID ¶
ID is a typed object ID (reference) to an instance of this class, use it to store references to objects with unknown lifetimes, as an ID will not panic on use if the underlying object has been destroyed.
type Instance ¶
Instance of the class with convieniently typed arguments and results.
var Nil Instance
Nil is a nil/null instance of the class. Equivalent to the zero value.
func (Instance) AsRefCounted ¶
func (self Instance) AsRefCounted() [1]gd.RefCounted
func (Instance) AsZIPReader ¶
func (Instance) FileExists ¶
Returns true if the file exists in the loaded zip archive.
Must be called after Open.
func (Instance) GetCompressionLevel ¶
Returns the compression level of the file in the loaded zip archive. Returns -1 if the file doesn't exist or any other error occurs. Must be called after Open.
func (Instance) GetFiles ¶
Returns the list of names of all files in the loaded archive.
Must be called after Open.
func (Instance) MoreArgs ¶
MoreArgs enables certain functions to be called with additional 'optional' arguments.
type MoreArgs ¶
MoreArgs is a container for Instance functions with additional 'optional' arguments.
func (MoreArgs) FileExists ¶
Returns true if the file exists in the loaded zip archive.
Must be called after Open.
func (MoreArgs) GetCompressionLevel ¶
Returns the compression level of the file in the loaded zip archive. Returns -1 if the file doesn't exist or any other error occurs. Must be called after Open.
