Hi��

I'm trying to understand what are the idioms in Smacc when converting from

ANTLR

######### the case of * ########################

Function = ���(��� (',' Arguments )* ���)���

�� �� ��should be transformed into��

Function

: <name> "(" 'leftParen' _ArgumentsOption ��")" 'rightParen' {{}}

;

_ArgumentsOption

:

| Arguments��

;

Arguments

: Expression 'argument'

| Arguments "," Expression 'argument'

;

Here since there is a recursion in Arguments��

the instance variable containing a list of argument will be added to the FunctionNode

Pay attention that Expression 'argument' should not have a {{}} nor its parent rule.

######### the case of + ########################

Function = ���(��� ��Arguments + ���)���

�� �� ��should be transformed into��

Function

: <name> "(" 'leftParen' _ArgumentsOption ��")" 'rightParen' {{}}

;

_ArgumentsOption

: Arguments��

;

Arguments

: Expression 'argument'

| Arguments "," Expression 'argument'

;

######### the case of ? ########################

Function = ���(��� ��Arguments+ ���)���

�� �� ��should be transformed into��

Function

: <name> "(" 'leftParen' _ArgumentsOption ��")" 'rightParen' {{}}

;

_ArgumentsOption

:

| Arguments��

;

Arguments

: Expression 'argument'��

;

Is there a more compact way to express?

Thierry do you have example of *, + , ? in the grammar?
