In the CindyScript input window you find a console for text output. For most practical purposes this will not be used for the final construction. However, it is extremely useful for debugging.


Printing text: print(<expr>)




Description: This operator prints the result of evaluating <expr> to the console.




Printing text: err(<expr>)




Description: Prints the result of evaluating <expr> to the console. If <expr> is a variable, the variable name is printed as well. Very useful for debugging.




Printing text: println(<expr>)




Description: This operator prints the result of evaluating <expr> to the console and adds a newline character to the end of the text.



Printing a newline: println()




Description: This operator prints a newline character to the console.




Clearing the console: clearconsole()




Description: Removes all text from the console.




Conditional print: assert(<bool>,<expr>)




Description: This operator is mainly meant for convenience purpose when generating own error mesages. it is equivalent to if(!<bool>,println(<expr>)). It can be used to test wheter a condition is met and otherwise generate an error message.



Example: A typical usage of this operator is the following:

assert(isinteger(k),"k is not an integer");




Output a status message: message(<expr>)




Description: This operator shows the result of evaluating <expr> in the status line of the application, or in the status line of the browser for Cinderella applets.
