Adding multiple mailaddresses to lain imap widget in awesome wm - imap

Question

I'd like to get help with configuring the lain imap widget in awesome wm. While I actually have 3 email addresses to care about I'd like to configure the lain widget, so that I have only one Mail-icon and three initialized imap widgets, who sum up the widgets mailcount variable, sending that to the widget.
The current state is this:
local mailicon = wibox.widget.imagebox(theme.widget_mail)
mailicon:buttons(awful.util.table.join(awful.button({ }, 1, function () awful.spawn(mailclient) end)))
local mail = lain.widget.imap({
timeout = 60,
server = mailserver,
mail = mailaddress,
password = mailpass,
is_plain = true,
settings = function()
if mailcount > 0 then
widget:set_text(" " .. mailcount .. " ")
mailicon:set_image(theme.widget_mail_on)
else
widget:set_text("")
mailicon:set_image(theme.widget_mail)
end
end
})
But I thought about something like this:
local mailicon = wibox.widget.imagebox(theme.widget_mail)
mailicon:buttons(awful.util.table.join(awful.button({ }, 1, function () awful.spawn(mailclient) end)))
local mail = lain.widget.imap({
timeout = 60,
server = mailserver,
mail = mailaddress,
password = mailpass,
is_plain = true,
settings = function()
--> local mailsum = mailcount
if mailsum > 0 then
widget:set_text(" " .. --> mailsum .. " ")
mailicon:set_image(theme.widget_mail_on)
else
widget:set_text("")
mailicon:set_image(theme.widget_mail)
end
end
})
local mail2 = lain.widget.imap({
timeout = 60,
server = "SECOND SERVER",
mail = "SECOND ADDRESS",
password = "SECOND PASS",
is_plain = true,
settings = function()
--> local mailsum = mailsum + mailcount
if mailsum > 0 then
widget:set_text(" " .. --> mailsum .. " ")
mailicon:set_image(theme.widget_mail_on)
else
widget:set_text("")
mailicon:set_image(theme.widget_mail)
end
end
})
(changes marked with --> ) Where a "mailsum" variable sums up the "mailcount" of every server. But I'm pretty new at lua coding and don't know how.
So the state I want to have in the end is one mail icon, and if I have one unread mail on first server and two on second, there should spawn a "3" behind the icon.
Can you help me?

Answer 1

If I understand you correctly mail2 should sum up the mail count for both mail addresses. The easiest solution would be to declare a variable outside of the widgets. So write something like local mailsum = 0 before declaring local mail. Both following mail widgets have access to the mailsum variable.
