need a loop for reading messages for logging [Solved]

[pvklink]

it is the dashticz environment....

[pvklink]

in the domoticz env it is ok...
strange thing is that my old scripts also write to this text device with

msgtxt = 'Alarm is uitgezet, scenes worden gedeactiveerd....'
timertekst = dz.time.rawDate .. ' ' .. dz.time.rawTime .. ' : ' .. msgtxt .. '<br>' .. dz.devices('timerlog').text
dz.devices('timerlog').updateText(timertekst)

and with this it works in dashticz and domoticz...

Lines attached is only when the script has executed more than one
globalMessage(add, message .. ' AVOND AAN: huiskamerverlichting wordt AAN gezet...')

before globalMessage() -- dump

When it concerns only one globalMessage(add, message .. ' AVOND AAN: huiskamerverlichting wordt AAN gezet...')
all went OK!

ok, that did not work even... my domoticz textfield gets extra linefeeds....

I have one config that both domoticz and dashticz are ok:
It works, so no need for digging

I have still two other issues:
one is releated to this log functionality.
When my script logs with ADD messages and calls another script with the same add messages calls, i loose some info....
looks difficult to solve that! a script can add more then one logs and write onetime and calls another script that also has more logs and also writes onetime. Logging must work in comination and seperate...

other is a new topic and more an advise how to split my script in parts
I will post it after my son is ready (needs my pc for exams..)

Logging works OK!
I am rewriting all my scripts to use this..

Only with ifttt control var script i cant find why it is missing a value!
i renamed action to actionx because ifttt and globalmessage uses action

I think that it has something to do with global_data
local trigger = item.isDevice and (", Device: " .. item.name ) or (", Timer: " .. item.trigger)
iftttvar i not a device or timer..

Only with ifttt control var script i cant find why it is missing a value!
I think that it has something to do with global_data
local trigger = item.isDevice and (", Device: " .. item.name ) or (", Timer: " .. item.trigger)
iftttvar i not a device or timer..

Yes, that is indeed why you see the error. Try and replace that part of global data with

Code: Select all

addMessage = 
        function(dz, item, info, message, messages)
            local trigger  
            if item.isDevice then trigger = ", Device: " .. item.name
            elseif item.isTimer then trigger = ", Timer: " .. item.trigger 
            elseif item.isVariable then trigger = ", Variable: " .. item.name 
            else trigger = ", Unknown trigger"
            end    
            messages[#messages + 1] = {}
            messages[#messages].log  = 'scriptname: ' .. info.scriptName .. trigger .. ' ' .. message
            messages[#messages].text = dz.time.rawDate .. '  ' .. dz.time.rawTime .. ' : ' .. message 
            --messages[#messages].text = dz.time.rawDate .. '  ' .. dz.time.rawTime .. ' : ' .. message .. '<br>'
            return messages
        end,

Yessssssssss, IFTTT now also works with the new logging...

Also made a script with a command to clean the log..

dz.devices('timerlog').updateText(dz.time.rawDate .. ' ' .. dz.time.rawTime .. ' :' .. ' TIMERLOG CLEAN: timerlog wordt geschoond...')

Or is it better to place this in your helper function ?

local function globalMessage(action, message )
if action == add then
messageTable = dz.helpers.addMessage(dz, item, info, message, messageTable )
elseif action == del then
dz.devices('timerlog').updateText(message)
else
dz.helpers.dumpMessages(dz, messageTable)
end
end

or even in the global_data ?

logging looks great!

looks great!

Last problem, is a hard one.
I have nested scripts an both scripts uses the globamessages at their own and in combination.
When this test scripts calls the usb lamp, only the usb lamps logs are shown not 0-1-2 from the testscript and when i remark the usb lamp, i do get the 0-1-2 from the testscript/

I thought this was easy to fix by adding extra globalMessage() -- dump before calling the nested script so all the current logs where written...
but no !

Code: Select all

return {
    on = { devices = { 'test' }},
    
    execute = function(dz, item, info)

    local messageTable = {}
    local add = 'add'
        
    local function globalMessage(action, message )
        if action == add then
            messageTable = dz.helpers.addMessage(dz, item, info, message, messageTable )
        else
            dz.helpers.dumpMessages(dz, messageTable)
        end
    end        -- dz.devices('timerlog').updateText(dz.time.rawDate .. '  ' .. dz.time.rawTime .. ' : leeg')

        globalMessage(add, ' test 0 voor usb')

        --globalMessage() -- dump
    
        dz.devices('usb lamp').switchSelector(40)   -- the script for usb lamp also writes to the log !!!when is is not remarked out the other logs are not visible
        --dz.devices('Bewegingsservice').switchOff()
        
        globalMessage(add, ' test 1 na usb')
        globalMessage(add, ' test 2 na usb')

        globalMessage() -- dump

end
}

}

A temporary solution for the nested scripts is to set some logging off
logcode 0 message rule not written, 1 = dom log, 2 txtbox log, 3 =all written
dont now if this is the way to do it....

global_data

Code: Select all

addMessage = 
        function(dz, item, info, message, messages, logcode)
	-- logcode 0=no message written, 1= message domoticz log written, 2 =message = textbox, 3= all written
	-- what if logcode nil is, then default = 3
	if logcode > 0 then
	            local trigger  
	            if item.isDevice then 
		trigger = ", Device: " .. item.name
	            elseif item.isTimer then 
		trigger = ", Timer: " .. item.trigger 
	            elseif item.isVariable then 
		trigger = ", Variable: " .. item.name 
	            else trigger = ", Unknown trigger"
	            end    
	            messages[#messages + 1] = {}
		if logcode =1 or logcode = 3 then
		            messages[#messages].log  = 'scriptname: ' .. info.scriptName .. trigger .. ' ' .. message
		if logcode =2 or logcode = 3 then
		            messages[#messages].text = dz.time.rawDate .. '  ' .. dz.time.rawTime .. ' : ' .. message 
		            --messages[#messages].text = dz.time.rawDate .. '  ' .. dz.time.rawTime .. ' : ' .. message .. '<br>'
		end
	end 
           return messages
        end,
    
    dumpMessages = 
        function(dz, messages)
            local textDevice = dz.devices('timerlog')
            local currentText = textDevice.text
            local newText = currentText
	    local lf = '<br>'
            --local lf = "\n"
            --local lf = "\r\n"
            local maxLines = 8
            
            for i, record in ipairs(messages) do
                dz.log(record.log, dz.LOG_INFO) 
                newText = record.text .. lf .. newText
            end
            
            dz.log(newText, dz.LOG_INFO)
            
            if newText ~= currentText then
                --lines = dz.utils.stringSplit(newText, lf)  -- create lines table from newText string
                --newText = table.concat(lines, lf, 1, (math.min(maxLines,#lines))) -- recreate newText string from first maxLines 
                textDevice.updateText(newText) 
            end    
        end,

Last problem, is a hard one.
I have nested scripts an both scripts uses the globamessages at their own and in combination.

There is no such thing as nested scripts in the domoticz Eventsystem.
The Eventsystem is single threaded meaning that a script needs to be finished before a next script can start.

[pvklink]

mmm,strange my testscript writes log messages ok when activate test and disabling the usb lamp that is calling its own script also with log messages...
but when enabling the usb lamp in the test script, the test logs get lost and only the usb lamp one appear
see the test script above...

mmm,strange my testscript writes log messages ok when activate test and disabling the usb lamp that is calling its own script also with log messages...

Probably because they both use the same domoticz object so there 'currenttext' is the same for both. A way to prevent this type of conflict is to get 'currenttext' from a variable in global data and not from the text device.

Got it working! THANKS again @WAAREN
The usb logging is showing up now!
Strange thing is that the USB logs are logged later!

1. is this a good way to add the delete function ? it is working...
2. do i need the dz parameter in
globalMessage(dz,del, dz.time.rawDate .. ' ' .. dz.time.rawTime .. ' :' .. ' TIMERLOG CLEAN: timerlog wordt geschoond...') -- delete
3. last thing is to add logcode 1,2,3 to addMessage to 1= log domoticz.log, 2= log global, 3 log both

then time for a holiday and no more scripting. I can check remote (via logs) if everything works ok!

2. do i need the dz parameter in

No. You don't need it.
don't forget to remove it from both the calls to the function and from the function declaration.

Works!

Busy with the last part.

want to call the logfunctie with the logcode: 0 no log, 1 = domoticz log, 2 = global var log, 3 = all
0 and 3 works ok!

globalMessage(add, ' BASISVOORZIENING AAN: ...',1)

this is the function:

Code: Select all

    local logcode = 3
    local messageTable = {}
    local add = 'add'
    local del = 'del'
    local chg = 'chg'
        
    local function globalMessage(action, message, logcode)
 
        if logcode == nil then logcode = 3 end
 
        if action == add and logcode > 0 then
            messageTable = dz.helpers.addMessage(dz, item, info, message, messageTable, logcode)
        elseif action == del then

        elseif action == chg then 
            dz.helpers.dumpMessages(dz, messageTable)
        end

logcode = 0 is working ok.

When using the parm 1, you don't enter anything in the text field of the messages record in function addMessage but in function dumpMessages you still expect something to be there. dzVents (Lua) is quite powerful but without a wand it cannot perform magic

Just curious why you would want to use these functions if you only want to send something to the logfile.

i have lot of devices (100) and lot of scripts and i am rewriting them all in dzvents, 99% is working but can be organized better...
so no more groups, triggers timers in domoticz, all in dzvents
So i have made a lot of checkpoints where i write to the logs when testing my script.
I write to domoticz (but that has a lot of entries and hard to search and i have my own log with the most important entries, events etc.

Some events i want to see in domoticz, some in my log and sometime when scripts are not working ok, i changes these logrules from ,0 to ,3 to see what is going wrong..

I am very happy with it and it works ok!
i understand the problem with value 1 and 2 now...when only write to domoticz and not to global i dont get something back...
so my local logging function has to split domoticz and global logging in two executing parts...?
