Mail Framework

Here's a listing of all the important pieces of the Mail Agent framework as implemented in Frontier.

  1. suites.mail.init

    if double (string.mid (Frontier.version (), 1, 3)) < 4.1
    scriptError ("The mail suite requires Frontier 4.1 or greater.")
    if not defined (user.mail)
    new (tabletype, @user.mail)
    if not defined (user.mail.agents)
    new (tabletype, @user.mail.agents)
    user.mail.agents.defaultFilter = mail.traps.defaultFilter
    if not defined (user.mail.prefs)
    new (tabletype, @user.mail.prefs)
    if not defined (user.mail.prefs.msgcount)
    user.mail.prefs.msgcount = 0
    if not defined (user.mail.prefs.enabled)
    user.mail.prefs.enabled = false
    if not defined (system.verbs.traps.CSOm)
    new (tabletype, @system.verbs.traps.CSOm)
    if not defined (system.verbs.traps.CSOm.eNot)
    system.verbs.traps.CSOm.eNot = mail.traps.CSOmeNot
    if not defined (system.startup.mail)
    system.startup.mail = mail.traps.startup
    if not defined (system.shutdown.mail)
    system.shutdown.mail = mail.traps.shutdown

  2. mail.traps.defaultFilter

    on defaultFilter (mailerappname, whatEvent, theList)
    «this is the default mail filter script
    «it just displays the message counter in Frontier's main window
    «we'll leave it to later (and others) to provide cool mail filters
    «whatEvent can take on the following values:
    «wHCn - hasConnected
    «wArv - mailArrives
    «wSnt - mailSent
    «wFil - opensFilters
    «wWcn - willConnect
    local (directionstring)
    case whatEvent «we only handle in and out events
    'wHCn'
    'wFil'
    'wWcn'
    return (true)

    directionstring = "in"
    'wSnt'
    directionstring = "out"
    if sizeof (thelist) > 0 «for debugging, if there's a problem we can repeat it in debugger
    scratchpad.enotlist = theList
    local (i, mailmsg)

    mail.otherRoot.close ()
    return (true)
    «bundle «test code
    «defaultFilter ("Eudora", 'wArv', scratchpad.enotlist)

  3. mail.traps.CSOmeNot

    on eNot (whatEvent, theList)

    local (i)
    for i = 1 to sizeOf (user.mail.agents)
    local (adr = @user.mail.agents [i])

    return (true)

  4. mail.traps.startup

    mail.init ()

    for i = 1 to sizeof (mail.drivers)
    try {mail.drivers [i].setNotification (true)}

  5. mail.traps.shutdown

    local (i)
    for i = 1 to sizeof (mail.drivers)
    try {mail.drivers [i].setNotification (false)}

  6. mail.enableFiltering

    on enableFiltering (fl) «if true, enable filtering; if false disable
    if user.mail.prefs.enabled == fl «nothing to do
    return
    user.mail.prefs.enabled = fl
    if fl «enabling
    mail.traps.startup ()
    else «disabling
    mail.traps.shutdown ()
    «bundle «test code
    «enableFiltering (true)

  7. suites.mail.drivers.Eudora.getMessageTable

    on getMessageTable (cookie, adrtable)
    local (s)
    with objectmodel, eudora, eventinfo
    s = get (cookie)
    «toys.newtextobject (s, @scratchpad.s) «for debugging

    bundle «special code that finds the text of the message
    if (sizeof (label) == 0) or (label contains cr)
    adrtable^.text = s
    return (false)

    «edit (@scratchpad.t)
    «window.zoom (@scratchpad.t)

  8. suites.mail.drivers.Eudora.setNotification

    on setNotification (flturnon)
    if flturnon
    Eudora.turnNotificationOn ()
    else
    Eudora.turnNotificationOff ()
