Query returns CamelCase string [message #1830098]

Hi,

I have a question regarding an Acceleo query to convert a snake to camel case string. I have problems to find the correct regex replace expression.

e.g.
snake_string = "camel_case" to CamelCase

[query public convertToCamelCase(snakeCase : String) : String = snakeCase.replaceAll('_([a-z])', '\\U$1').toUpperFirst()/]

with that query I get
CamelUcase. It seems '\\U$1' is the wrong expression. The 'U' is not recognized to convert the backtrace $1.

Best regards
Michael

Hi

I suggest you debug it in Java / ask on a Java forum since the Acceleo implementation almost certainly just calls a Java routine mindlessly.

Hi Ed,

I have checked the replaceAll(...) function in a Java wrapper. The same behavior, it seems, it is not foreseen to manipulate the backtrack $1 in such a way.
I write an own function to do this.
