Hi,

I'm having a little issue with Lists in xtend. Here is my problem:

I have these functions:

String transformDec(ada::single_task_declaration task) :
	"task "+task.identifier+" is\n"+task.entryDec.transformDec()
	+"end "+task.identifier+";\n"
;

String transformDec(ada::entry_declaration entry) :
	"entry "+entry.identifier+";\n"
;

entryDec is a List of objects of type entry_declaration and the generated code is like this:

task Component_acces1 is
[entry r1_reponsePositive;
, entry r1_reponseNegative;
, entry r1_voitureArrive;
]end Component_acces1;

I don't need the brackets and commas, i want it to be like this :

task Component_acces1 is
entry r1_reponsePositive;
entry r1_reponseNegative;
entry r1_voitureArrive;
end Component_acces1;

Your help is much appreciated!

hello,

just call toString("") on your list: task.entryDec.transformDec().toString("")

You should use Xpand to generate the code.

«DEFINE transformDec FOR ada::single_task_declaration-»
task «this.identifier» is
«FOREACH this.entryDec AS entry-»
  «entry.identifier»;
«ENDFOREACH-»
end «this.identifier»;
