Zip Files in a Date Range

See more Zip Examples

Demonstrates how to use the Zip.MinDate and Zip.MaxDate properties to zip 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 requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

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

    const zip_path = "c:/temp/qa_output/out.zip";

    // Initialize the zip object with the path of the .zip to be created.
    zip.newZip(zip_path) catch {};

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

    // Also, only append 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 appending files.

    // Recursively append to the zip object the paths of the files and directories in a directory tree.
    // At this point we are not creating the .zip, nor are we reading the contents of the files.
    // We are simply appending references to the files and directories in the local filesystem
    // that will get processed when WriteZip is called.
    const recurse = true;
    zip.appendFiles("c:/temp/files_to_zip", recurse) catch {
        std.debug.print("{s}\n", .{try zip.getLastErrorText(alloc)});
        return;
    };

    zip.setFileName(zip_path);
    zip.writeZip() catch {
        std.debug.print("{s}\n", .{try zip.getLastErrorText(alloc)});
        return;
    };

    zip.closeZip();

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