Send Email with a vCard

Demonstrates how to create a simple email, attach a vcard, and send it. 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.

    // The mailman object is used for sending and receiving email.
    const mailman = try chilkat.MailMan.init();
    defer mailman.deinit();

    // Set the SMTP server.
    mailman.setSmtpHost("smtp.chilkatsoft.com");

    // Set the SMTP login/password (if required)
    mailman.setSmtpUsername("myUsername");
    mailman.setSmtpPassword("myPassword");

    // Create a new email object
    const email = try chilkat.Email.init();
    defer email.deinit();

    email.setSubject("This is a vcard test");
    email.setBody("This is a vcard test");
    email.setFrom("Chilkat Admin <admin@chilkatsoft.com>");
    try email.addTo("Chilkat Support", "support@chilkatsoft.com");
    // To add more recipients, call AddTo, AddCC, or AddBcc once per recipient.

    // A vCard is an email attachment having a Content-Type = "text/x-vcard".
    // Call AddStringAttachment to add a vcard from an in-memory string.
    // The filename should have a ".vcf" file extension.  Chilkat will automatically
    // recognize it and set the content-type to "text/x-vcard";

    // Your application is responsible for providing the vcard formatted string.  For example:
    // See http://en.wikipedia.org/wiki/VCard
    //
    // begin:vcard
    // fn:Matt Smith
    // n:Smith;Matt
    // org:Chilkat Software, Inc.
    // tel;work:630-784-9670
    // url:http://www.chilkatsoft.com
    // version:2.1
    // end:vcard

    const vcard = "begin:vcard ...";
    email.addStringAttachment("admin.vcf", vcard) catch {
        std.debug.print("{s}\n", .{try email.getLastErrorText(alloc)});
        return;
    };

    // Call SendEmail to connect to the SMTP server and send.
    // The connection (i.e. session) to the SMTP server remains
    // open so that subsequent SendEmail calls may use the
    // same connection.
    mailman.sendEmail(email) catch {
        std.debug.print("{s}\n", .{try mailman.getLastErrorText(alloc)});
        return;
    };

    // Some SMTP servers do not actually send the email until
    // the connection is closed.  In these cases, it is necessary to
    // call CloseSmtpConnection for the mail to be  sent.
    // Most SMTP servers send the email immediately, and it is
    // not required to close the connection.  We'll close it here
    // for the example:
    mailman.closeSmtpConnection() catch {
        std.debug.print("Connection to SMTP server not closed cleanly.\n", .{});
    };

    std.debug.print("Mail with vCard Sent!\n", .{});
