Unzip all Files to a Single Directory (Ignoring Subdirectories in Zip)

See more Zip Examples

Demonstrates how to unzip all files into a single directory, ignoring the internal directory structure of the files in the .zip. Zig

const std = @import("std");
const chilkat = @import("chilkat");

pub fn main(init: std.process.Init) !void {
    const alloc = init.arena.allocator();

    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    const out_dir = "c:/temp/testUnzipDir";

    // Make sure our output directory exists.
    const fac = try chilkat.FileAccess.init();
    defer fac.deinit();
    fac.dirEnsureExists(out_dir) catch {
        std.debug.print("{s}\n", .{try fac.getLastErrorText(alloc)});
        return;
    };

    const zip = try chilkat.Zip.init();
    defer zip.deinit();

    // In this example, the xml_files.zip contains some files in the subdirectories "dir1" and also "dir2/dir3".

    // a1.xml
    // b1.xml
    // c1.xml
    // dir1/a2.xml
    // dir1/c2.xml
    // dir2/dir3/c3.xml

    zip.openZip("qa_data/zips/xml_files.zip") catch {
        std.debug.print("{s}\n", .{try zip.getLastErrorText(alloc)});
        return;
    };

    // Unzip all files into the directory c:/temp/testUnzipDir
    const num_unzipped = zip.unzipInto(out_dir);
    if (num_unzipped < 0) {
        std.debug.print("{s}\n", .{try zip.getLastErrorText(alloc)});
        return;
    }

    std.debug.print("Num unzipped = {d}\n", .{num_unzipped});

    // After unzipping via UnzipInto, we have this:

    // c:\temp\testUnzipDir\a1.xml
    // c:\temp\testUnzipDir\b1.xml
    // c:\temp\testUnzipDir\c1.xml
    // c:\temp\testUnzipDir\a2.xml
    // c:\temp\testUnzipDir\c2.xml
    // c:\temp\testUnzipDir\c3.xml

    zip.closeZip();

    std.debug.print("Success.\n", .{});
