Lua Requires Chilkat v11.0.0+

Sorting Email

Demonstrates how to sort an email bundle. Lua

local chilkat = require("chilkat")

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

local imap = chilkat.Imap.new()

-- Connect to the IMAP server.
-- Use TLS
imap.ssl = true
imap.port = 993
local success = imap:connect("imap.example.com")
if not success then
    print(imap.last_error_text)
    return
end

-- Login
success = imap:login("myLogin", "myPassword")
if not success then
    print(imap.last_error_text)
    return
end

-- Select an IMAP mailbox
success = imap:select_mailbox("Inbox")
if not success then
    print(imap.last_error_text)
    return
end

local fetchUids = true
local messageSet = chilkat.MessageSet.new()
success = imap:query_mbx("ALL", fetchUids, messageSet)
if not success then
    print(imap.last_error_text)
    return
end

-- Fetch the email headers into a bundle object:
local bundle = chilkat.EmailBundle.new()
local headersOnly = true
success = imap:fetch_msg_set(headersOnly, messageSet, bundle)
if not success then
    print(imap.last_error_text)
    return
end

-- Sort the email bundle by date, recipient, sender, or subject:
local ascending = true
bundle:sort_by_date(ascending)

-- To sort by recipient, sender, or subject, call
-- SortBySender, SortByRecipient, or SortBySubject.

-- Display the Subject and From of each email.
local email = chilkat.Email.new()
local i = 0
while i < bundle.message_count do
    bundle:email_at(i, email)

    print(email:get_header_field("Date"))
    print(email.subject)
    print(email.from)
    print("--")

    i = i + 1
end

-- Disconnect from the IMAP server.
success = imap:disconnect()
