Using RingZip

In this chapter we will learn about using RingZip

Create Zip File

Example : Create myfile.zip contains 4 files

load "ziplib.ring"
oZip = zip_openfile("myfile.zip",'w')
zip_addfile(oZip,"test.c")
zip_addfile(oZip,"zip.c")
zip_addfile(oZip,"zip.h")
zip_addfile(oZip,"miniz.h")
zip_close(oZip)

Extract Zip File

Example : Extract myfile.zip to myfolder folder.

load "ziplib.ring"
zip_extract_allfiles("myfile.zip","myfolder")

Print Files in Zip file

Example : Print file names in the myfile.zip

load "ziplib.ring"
oZip = zip_openfile("myfile.zip",'r')
for x=1 to zip_filescount(oZip)
       see zip_getfilenamebyindex(oZip,x) + nl
next
zip_close(oZip)

Using RingZip Classes

The RingZip library comes with two classes. The Zip class and the ZipEntry class.

Example (1):

load "ziplib.ring"

new Zip {
        setFileName("myfile.zip")
        open("w")
        newEntry() {
                open("test.c")
                writefile("test.c")
                close()
        }
        close()
}

Example (2):

load "ziplib.ring"

new Zip {
        SetFileName("myfile.zip")
        Open("w")
        AddFile("test.c")
        AddFile("zip.c")
        AddFile("zip.h")
        AddFile("miniz.h")
        Close()
}

Example (3):

load "ziplib.ring"

new zip {
        SetFileName("myfile.zip")
        ExtractAllFiles("myfolder")
}

Example (4):

load "ziplib.ring"

new Zip {
        SetFileName("myfile.zip")
        Open("r")
        see FilesCount()
        Close()
}

Example (5):

load "ziplib.ring"

new Zip {
        SetFileName("myfile.zip")
        Open("r")
        for x = 1 to filescount()
                See GetFileNameByIndex(x) + nl
        next
        Close()
}
