This is so basic that I thought I should be able to find a solution, but I have not.
What I want to do is parse a text string into separate parts.
Is there a way in dzVents to do this?

Hi, I think there are specific additions to Lua in dzVents for string manipulation in domoticz.utils._
See https://www.domoticz.com/wiki/Lodash_documentation
There are also the lua language string manipulation functions documented http://lua-users.org/wiki/StringLibraryTutorial and for splitting strings, see http://lua-users.org/wiki/SplitJoin

Can you please elaborate a bit on this question It's now too generic to give a conclusive answer.
Maybe domoticz.utils.stringSplit(string, seperator) function is what you are looking for ?

I want to separate the return text from an "uptime" command in my Raspberry.
It returns this:

Code: Select all

01:26:00 up 7 days, 10:32, 0 users, load average: 0.21, 0.14, 0.10

I want to keep only this part:

Code: Select all

01:26:00 up 7 days, 10:32

So a simple split on the second comma would do it, I think

local result = "01:26:00 up 7 days, 10:32, 0 users, load average: 0.21, 0.14, 0.10"

local splittedResult = domoticz.utils.stringSplit(result,',')  -- split string into (table) parts with , as separator
domoticz.log(splittedResult[1] .. ',' .. splittedResult[2], domoticz.LOG_FORCE) -- first two parts

Great... I had to modify the code a little to work:

Code: Select all

        local utils = require("Utils") 
        local splittedResult = utils.stringSplit(uptime,',')

With this, it works fine.
Thanks!

@manjh, if you're interested in the uptime... May I suggest to look at this plugin https://github.com/Xorfor/Domoticz-PiMonitor-Plugin. It contains als gives you a device with the uptime and a lot of other info to monitor the health of your pi.

You should never have to require("Utils") in dzVents scripts.

Probably your first parm to execute = function is not domoticz but dz
Then the call become

Code: Select all

        local splittedResult = dz.utils.stringSplit(uptime,',')

I installed the plugin. Very interesting! There's a lot of information here... thanks!
