This module is imported into global table and available in any module through variable m. It allows you to access basic features of Miranda NG core.
Parameters written in bold italics are obligatory.
Constants
NULL
Null pointer.
- Type: light userdata
INVALID_HANDLE_VALUE
Invalid descriptor.
- Type: light userdata
CALLSERVICE_NOTFOUND
Result of service call when service does not exist.
- Type: number
Named events
CreateHookableEvent
Creates a hookable event.
- Parameters
- name
- Type: string
- Event name.
- Result
- Type: light userdata
- Returns event handle if event was created successfully, otherwise nil.
- Example
local hEvent = m.CreateHookableEvent('MyEvent')
if hEvent == m.NULL then
print('Event handle is empty!')
end
HookEvent
Sets a callback function ("hook") to react to event call. Hook are called one by one in the order they were added to the sequence.
Hook signature: function (wParam, lParam) return 0 end
.
Correct result for a trap is 0. When 1 is returned, the following hooks in a sequence won't be called.
- Parameters
- name
- Type: string
- Event name.
- hook
- Type: function
- Hook function to be called when event occurs.
- Result
- Type: light userdata
- Returns trap handle if trap was created successfully, otherwise nil.
- Example
local hHook = m.HookEvent('MyEvent', function(w, l)
print('MyEvent is raised!')
end)
UnhookEvent
Removes hook from event call sequence.
- Parameters
- hEvent
- Type: light userdata
- Event descriptor received on CreateHookableEvent call.
- Result
- Type: boolean
- Returns true if trap function was removed successfully, otherwise false.
- Example
m.UnhookEvent(hHook)
NotifyEventHooks
Calls all hooks of event call sequence one by one.
- Parameters
- hEvent
- Type: light userdata
- Event descriptor received on CreateHookableEvent call.
- wParam
- lParam
- Result
- Type: boolean
- Returns true if all hooks were called, otherwise false.
- Example
m.NotifyEventHooks(hEvent)
Named service functions
CreateServiceFunction
Creates a service function ("service")
- Parameters
- name
- Type: string
- Service name.
- Result
- Type: light userdata
- Returns service handle if service was created successfully, otherwise nil.
- Example
local hService = m.CreateServiceFunction('MyService', function(w, l)
print('MyServiceis called!')
end)
CallService
Calls service with parameters.
- Parameters
- name
- Type: string
- Service name.
- wParam
- lParam
- Result
- Type: number
- Returns result of service execution or CALLSERVICE_NOTFOUND
- Example
local result = m.CallService('MyService')
if result == m.CALLSERVICE_NOTFOUND then
print('Service is not found!')
end
ServiceExists
Checks if service exists by its name.
- Parameters
- name
- Type: string
- Service name.
- Result
- Type: boolean
- Returns true if service exists, otherwise false
- Example
if m.ServiceExists('MyService') then
m.CallService('MyService')
end
DestroyServiceFunction
Destroys a service function.
- Parameters
- hService
- Type: light userdata
- Service descriptor received on CreateServiceFunction call.
- Example
m.DestroyServiceFunction(hService)
Others
IsPluginLoaded
Checks if plugin is loaded by its UUID.
- Parameters
- uuid
- Type: string
- Plugin UUID in format xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx.
- Result
- Type: boolean
- Returns true if plugin is loaded, otherwise false.
- Example
if m.IsPluginLoaded('{F0FDF73A-753D-499d-8DBA-336DB79CDD41}') then
print('Advanced auto away plugin is loaded!')
end
Utf8DecodeA
Converts Lua string contents to ANSI (codepage of the current langpack is used).
- text
- Type: string
- Result
- Type: string
- Example
m.CallService("Quotes/Import", 0, Utf8DecodeA('c:\\quotes.xml'))
Utf8DecodeW
Converts Lua string contents to Unicode (UTF-16).
- text
- Type: string
- Result
- Type: string
- Example
m.CallService("Popup/ShowMessageW", m.Utf8DecodeW('Hello, World!'), 2)
Translate
Translates a string into the language of the current langpack.
- text
- Type: string
- Result
- Type: string
- Example
m.Translate('Exit')
ReplaceVariables
Replaces Miranda NG variables in a string.
- text
- Result
- Type: string
- Example
local profileName = m.ReplaceVariables('%miranda_profilename%')
