Zig Requires Chilkat v11.0.0+

Delete All IMAP Email

Demonstrates two ways to delete all email in a mailbox on an IMAP server. 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 imap = try chilkat.Imap.init();
    defer imap.deinit();

    // Turn on session logging:
    imap.setKeepSessionLog(true);

    // Connect to an IMAP server.
    // Use TLS
    imap.setSsl(true);
    imap.setPort(993);
    imap.connect("imap.example.com") catch {
        std.debug.print("{s}\n", .{try imap.getLastErrorText(alloc)});
        return;
    };

    // Login
    imap.login("myLogin", "myPassword") catch {
        std.debug.print("{s}\n", .{try imap.getLastErrorText(alloc)});
        return;
    };

    // Select an IMAP mailbox
    imap.selectMailbox("Inbox.RubyMail") catch {
        std.debug.print("{s}\n", .{try imap.getLastErrorText(alloc)});
        return;
    };

    // Get the complete set of Uids for email in the selected mailbox.
    const message_set = try chilkat.MessageSet.init();
    defer message_set.deinit();
    imap.queryMbx("ALL", true, message_set) catch {
        std.debug.print("{s}\n", .{try imap.getLastErrorText(alloc)});
        return;
    };

    // Set the Deleted flag for each message.
    // (ExpungeAndClose must be called to finalize the delete.)
    imap.setFlags(message_set, "Deleted", 1) catch {
        std.debug.print("{s}\n", .{try imap.getLastErrorText(alloc)});
        return;
    };

    // Alternatively, the Deleted flag may be set for each UID
    // individiually, but this is less efficient:
    var i: i32 = 0;
    const n = message_set.getCount();
    while (i < n) {
        imap.setFlag(message_set.getId(i), message_set.getHasUids(), "Deleted", 1) catch {
            std.debug.print("{s}\n", .{try imap.getLastErrorText(alloc)});
            return;
        };

        i = i + 1;
    }

    // Expunge and close the mailbox.
    imap.expungeAndClose() catch {
        std.debug.print("{s}\n", .{try imap.getLastErrorText(alloc)});
        return;
    };

    // Display the session log.
    std.debug.print("{s}\n", .{try imap.getSessionLog(alloc)});

    // Disconnect from the IMAP server.
    try imap.disconnect();
