Unzip Files in a Date Range

See more Zip Examples

Demonstrates how to use the Zip.MinDate and Zip.MaxDate properties to unzip only those files with a last-modified date within a date range.

Note: This example requires Chilkat v10.0.0 or greater.

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

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

    // The MinDate and MaxDate properties use the timestamp date/time string format.
    // Here are some examples:
    // YYYY-MM-DD (e.g., 2024-07-31)
    // YYYY-MM-DDTHH:MM:SS�HH:MM (e.g., 2024-07-31T12:34:56+02:00)
    // 2024-07-31T12:34:56Z (the "Z" denotes Zulu time, or UTC)

    // Only unzip files having a last-modified date greater than 1-Jan-2017
    zip.setMinDate("2017-01-01T00:00:00Z");

    // Also, only unzip files having a last-modified date less than the end of 2020
    zip.setMaxDate("2020-12-31T23:59:59Z");

    // You don't need to specify both MinDate and MaxDate.
    // You can specify only one or the other if needed.

    // The MinDate/MaxDate properties apply to all of the Chilkat methods for unzipping.

    const num_unzipped = zip.unzip("c:/temp/unzipDir");
    if (num_unzipped < 0) {
        std.debug.print("{s}\n", .{try zip.getLastErrorText(alloc)});
        return;
    }

    zip.closeZip();
