Visualisation time and date Question

So probably a very basic question. i have done the 1 day basic nac and shac programming course so i have a basic understanding. One thing that i guess was not covered that i am struggling to find any information on was a time and date timestamp that i could have on a theme to display on the header of every page. I believe it must be coded as i have tried creating an object "user Parameter/TimeDate" but this is just static text. I have seen some images with time and date stamps on some Clipsal themes here.

thanks.

 

To show the time and date, we have done this;

1. Create three string User Parameters(i.e. named Viz_Time, Viz_Date, Viz_AMPM)



2. Create Resident script with 60 second interval


3. With script contents of this;
SetUserParam('Local', 'Viz_Time', os.date("%I:%M"))
SetUserParam('Local', 'Viz_AMPM', os.date("%p"))
SetUserParam('Local', 'Viz_Date', os.date("%A, %B %d, %Y"))

4. We also put this line into the Startup script to make sure the date is updated on NAC power up;
SetUserParam('Local', 'Viz_Date', os.date("%A, %B %d, %Y"))

5. Then in the Visualisation add objects to show the values of the new User Parameters

 

I'm sorry, I'm very new to all of this....Has anyone been able to get this script to work?
Questions:

1. In Step 3 is this one script or one script for each of the parameters?
2. In Step 3 is this script correct? When I paste it into the contents of the script I get the following error. The script cannot be saved "Lua syntax error at line 1: unfinished string near '"%I:%M'"
3. Also in Step 4 where do, I put the startup script?

 

Step 3 is one script. Select Scripting, then Resident Scripts. Add all three lines in.
The forum screws up quoted strings. It should read:

Code:

SetUserParam('Local', 'Viz_Time', os.date("%I:%M"))

SetUserParam('Local', 'Viz_AMPM', os.date("%p"))

SetUserParam('Local', 'Viz_Date', os.date("%A%d, %Y"))

Under scripting, select Start UP (Init) Script.

If anyone reads this and is pasting scripts. Please use the CODE formatting option

 

Thanks for your update I was able to get through that step.
I have also added this script to the start-up and run it.
The final part adding the Visualisation is not giving me the current date and time, do you have any idea why this would be?

 

I'm still having trouble with this script. The date seems to be working fine just not the time. When I put the script for Viz_Time into the screen it works. However, when I go via the actual editor I get errors. Any help wopuld be appreciated.

 

i do it in a resident script with 0 delay like this which updates the time to user parameter with type string when the seconds hit 00 have a look at https://www.lua.org/pil/22.1.html for all the variants on the time and date etc

if os.date("%S") == '00' then
SetUserParam('Local', 'Time', os.date("%H:%M"))
end

 

Hi Guys,
I managed to make a date/time from your instruction,whoever i needed to do some changes to work
SetUserParam('<mynetwork>', 'Viz_Time', os.date("%I:%M"))
SetUserParam('<mynetwork>', 'Viz_AMPM', os.date("%p"))
SetUserParam('<mynetwork>', 'Viz_Date', os.date("%A %d, %Y"))

<mynetwork>= my cbus network name

Thanks Dic

 

Hi Ashley,
this is my very first scripting attempt and I seem to be having the same problem as Antdwyer3875 and coming up with this error "Lua syntax error at line 1: unfinished string near '"%I:%M'".

first question what is "CODE formatting option" ?
second question 'local' = my network? which in my case is 'Cbus SHAC' so I'm assuming that I just replace 'local' with 'Cbus SHAC' ?
Ive tried every combination but continually return "Lua syntax error at line 1: unfinished string near '"%I:%M'"

I would like to feel like I'm moving forward with this but its a slow process
Ash

 

Lua strings can be enclosed in either single quotes (i.e apostrophes) or double quotes, but you must be consistent. Your string mixes these up.

This is a forum option (like quotes) that formats code for readability when posting on the forum. It does a better job (although not perfect) of preserving special characters often used in code. Without it, quote characters are often corrupted. This is a bug in the forums that has never been fixed.

'local' refers to which cbus network the command is destined for. The default network (the one your SHAC is connected to) is called 'local' by default. Most domestic installs will only have a single network and it should be called 'local', so just use 'local' whenever you see a 'net' parameter. If you have renamed your local cbus network to 'Cbus SHAC' use that, but I don't recommend this as you will just confuse anyone else looking at your system.

If you have a coding error, you need to post the actual code in error. Just posting the error message doesn't help us helping you (And when you post it, make sure the forum hasn't mangled it)

 

thank you Ashley
Ive tried to cut and paste the 3 lines from point 3 in dic's post.

SetUserParam('Local', 'Viz_Time', os.date("%I:%M
SetUserParam('Local', 'Viz_AMPM', os.date("%p
SetUserParam('Local', 'Viz_Date', os.date("%A%d, %Y"))

not sure if its meant to be 1 line of script ( I have tried as 1 line of script)
is it meant to be 3 separate lines in a single script as you stated above ? ( I have tried that as well)

still getting error report Lua syntax error at line 1: unfinished string near '"%I:%M'

 

They are 3 separate lines.

The problem is the forum screws up the end of the statements.

The first 2 lines need a double quote (i.e. a single character, not 2 single quotes) and 2 closing brackets on the end
The third line needs a double quote between the %d and the 2 closing brackets.

 

Thank you Ashley, now it makes complete sense.

 

Hi Ashley,
I've got no idea about Lua and the difference in double quote, single character and 2 single quotes, would it be possible to clarify it for me?

 

You can use either single quotes or double quotes to surround a string but the start and end quote must be the same character. This is handy if the string contains a quote charater, just use the other one to enclose the string. Two single quotes are only ever used to create an empty string (and you can also use 2 double quotes for the same purpose.) If you google "lua quote characters" you will gets lots of examples.

 

Hi all,

I'm new to Shac and lua coding so pardon my ignorance.

I've been working on a project were I need to display time and date on a third party screen I have.
I have followed above posts/replies but still cant get it to work.

My progress so far:

Setup 3 x user parameters.



Setup init script.



and resident script.



Errors im getting in script error logs.



Can someone please help!!!!!

 

You have created Vis_ with an s and then access it with Viz with a z

 

Thank You Ashley.

That worked !!!

Now I'm totally embarrassed.
