curly braclet in a StringTemplate

Question

The following StringTemplate gives me an "invalid character '}'" exception because of the closing curly brace after return null;:

$StatementList:{statement | 
public T $statement$(X x) { return null; }  }$

I want to have an output like:

public T statement1(X x) {return null; }
public T statement2(X x) {return null; }

How can I escape this closing curly brace?

Answer 1

I couldn't find a way of escaping characters, but I did manage to get it to work using the unicode character for curly braces instead.

statementTemplate(StatementList) ::= <<
<StatementList:{statement | 
public T <statement>(X x) <\u007B> return null; <\u007D> }>
>>

which produced:

public T statement1(X x) { return null; } 
public T statement2(X x) { return null; } 
public T statement3(X x) { return null; }

Answer 2

Backslash (\) worked for me:

$StatementList:{statement | 
public T $statement$(X x) { return null; \}  }$

It seems it is not necessary to escape the opening curly bracket.
