LUA, include file

[gertlind1]

I have a bunch of functions() that i use in my LUA scripts.
Is it possible to have those in a separate file instead of copy them to all my LUA scripts?

I have recently started to use the the built in LUA editor if that matters.

I don't know for built in editor. But with file, you can do like this :
json = (loadfile "/home/pi/domoticz/scripts/lua/json.lua")() -- For Linux
json = (loadfile "D:\\Domoticz\\scripts\\lua\\json.lua")() -- For Windows

See example here : https://www.domoticz.com/wiki/Lua_-_json.lua

I dont think the lua editor actually saves files on the filesystem, so your lua include is going to have to be maintained externally..

for me I created a folder /usr/local/share/lua/5.2 and linked a file called libs.lua into that folder.

see: https://github.com/nayrnet/domoticz-scr ... a/libs.lua

then here is an example usage in a script:
https://github.com/nayrnet/domoticz-scr ... ntdoor.lua

Thanks guys.
i will play around with it,

Of course I can't get it to work.

Created the /usr/local/share/lua/lua5.2/
Created a file there named libs.lua

Code: Select all

local libs = {};

function GroupState(sArray)
        -- v1.0. 2016-01-18
        -- Checks the state of a group of swithces.
        -- USAGE   : GroupState({'Switch1','Switch2','Switch3','Switch4','Switch5',more switches})
        -- RETURNS : 'On'       if all switches are on.
        --         : 'Off'      if all switches are off.
        --         : 'Mixed"    if one or more, but not all switches are on.
        --
        local iState = 0
        local iCount = 0
        local sState = ''
        for i,light in pairs(sArray) do
                if (otherdevices[light] == 'On') then
                        iState = iState + 1
                end
        iCount = iCount + 1
        end
        if(iState == 0) then sState = "Off" end
        if(iState > 0) then sState = 'Mixed' end
        if(iState == iCount) then sState = 'On' end
--      print("iCount   : " .. iCount)
--      print("iState   : " .. iState)
--      print("sState   : " .. sState)
        print "LIBS LUA"
        return sState
end

return libs

made the soft link in my /domoticz/scripts/lua/

Code: Select all

libs.lua -> /usr/local/share/lua/5.2/

calling it from here

Code: Select all

commandArray = {}
libs = require("libs")
aLivingroom = {'Hörnbord','Soffbord','Blomma','Fönster','Bokhylla'}
sCounterName = 'Rörelse räknare'

if (devicechanged['Rörelse'] == 'On' and libs.GroupState(aLivingroom) == 'Off') then
        time = os.date("*t")
        if (SunSet() < 60 and time.hour <= 20) then
                commandArray['Group:Alla Vardagsrum']='On'
        end
        if(time.hour >= 21) then
            commandArray['Hörnbord']='On FOR 1'
        end
else
        difference = TimeDifference('Rörelse')
        myTime = SecondsToClock(tostring(difference))
        commandArray['UpdateDevice'] = '10|0|'..myTime..' sedan senaste rörelsen.'
end
return commandArray

Getting this error:

Code: Select all

Error: EventSystem: in /home/pi/domoticz/scripts/lua/script_device_motion.lua: /home/pi/domoticz/scripts/lua/script_device_motion.lua:75: attempt to call field 'GroupState' (a nil value)

[gertlind1]

Forget it.
I cannot read or my glasses are dirty.

missed this
function lGroupState(sArray)

Did not add the "libs."GroupsState(sArray)

Works fine now.
Will move all my functions to libs.lua.

Tanks for the tip and the instruction.

Scripts created through the script editor are stored in the database but the only difference is how they are loaded by Domoticz prior to being handed to the Lua engine. Functionally external file inclusion should work the same way regardless of where the script is stored.

Yes, works fine.

Added a lua script in the Domoticz internal editor

Code: Select all

libs = require("libs")

commandArray = {}
if (otherdevices['Rörelse'] == 'On') then
    print ('Time to Sunset : ' .. libs.SecondsToClock(tostring(libs.SunSet())))
end
return commandArray

Works as a charm.

Code: Select all

2016-03-12 16:09:23.602  LUA: Time to Sunset : 00:01:33

Would it be possible to have the "functions file" libs.lua in the internal editor also?
That would be great.

Maybe if libs.lua is put in domoticz/scripts/lua
and the soft link that points to lib.lua is in the /usr/local/share/lua/lua5.2/

??
