CONSOLE TO PRINT THE DATA OF LOCAL VARIABLE

Is there any feasability to print the value of a local variable in the runtime & the value it has in the console. (Like other programming languages for debugging)

Hi [mention:7512a2ef378b4c43b97ae5b058da940b:e9ed411860ed4f2ba0265705b8793d05] what is your requirement initially, why would you like to print value in runtime. AFAIK I wouldn't be possible print the value of a local variable directly during runtime. Appian doesn't provide a built-in console for real-time debugging.

Can you tell me where you expect runtime values in the code, and What do you want to achieve it? An example would be great.

I don't have any specific requirement for that; I was just wondering if it exists.

While performing actions on the site, we can observe the values that local variables hold and how routing occurs based on the print statements.

Runtime printed values aid in faster debugging.

Hopefully, this tool will evolve to include a console in upcoming releases.

No built-in console printing for local variables, but workarounds exist
Display value in Interface, Add text/paragraph component showing the variable value(Mostly developer follow this for interface debugging)

What kind of variables and which runtime do you mean?

If you are saying that in expression rule you want to get an output through localvarible yes that is possible but I am not sure what do you mean by runtime

you may do it like

a!localVariables(

local!a: 4,

local!b: 5,

local!c: local!a +local!b,

local!c

)

this will print the local!c in the output in expression rule

In addition, If you want to print local variable value in logs, you can try logmessage plug-in (community.appian.com/.../log-a-message).

a!localVariables(
  local!data: "Message printed by logmessage function..........",
  local!info: logmessage("ERROR", local!data),
  local!data
)

Output:

The following will be printed in tomcat-stdOut.log file:
2024-06-11 07:24:30,614 [http-nio-8080-exec-995] ERROR com.incessant.plugins.logMessageMain.LogMessage - Message printed by logmessage function..........

I hope this helps.
