Apparently there is an interaction with the root directives.��

Now I tried to hook modifier logic to test and I cannot have two modifiers.

I thought that��

modifiers��

: modifier 'modifier'

| modifiers modifier 'modifier'

;

allows one to have 'public static' but apparently not so I'm totally confused.

Hi john

I'm learning smacc as a challenge :) I read a review the tutorial that we extracted form your doc.

I have the following expression��

FunctionTypeName = 'function' TypeNameList ( 'internal' | 'external' | 'constant' | 'payable' )* ( 'returns' TypeNameList )?

and I started to handle the 'internal'....

Now my grammar does not succeed to parse

��(self parser parseFunctionTypeNameOptions: 'internal payable')

Attempt one: did not work

===================

FunctionTypeNameOptions

: {{}}

| ��FunctionTypeNameOptions "internal" 'option' {{}}

| ��FunctionTypeNameOptions "external" 'option' {{}}

| ��FunctionTypeNameOptions "constant" 'option' {{}}

| ��FunctionTypeNameOptions "payable" 'option' {{}}

Attempt two: did not work

===================

FunctionTypeNameOptions

:��

| FunctTypeNameOptions

;

FunctTypeNameOptions

: ��FunctTypeNameOptions "internal" 'option' {{}}

| ��FunctTypeNameOptions "external" 'option' {{}}

| ��FunctTypeNameOptions "constant" 'option' {{}}

| ��FunctTypeNameOptions "payable" 'option' {{}}

;

Attempt three: did not work

=====================

FunctionTypeNameOptions

:��

| FunctTypeNameOptions

;

FunctTypeNameOptions

: FunctTypeNameOption 'option'

| FunctTypeNameOptions FunctTypeNameOption 'option'

;

FunctTypeNameOption

: ��"internal" 'option' {{}}

| ��"external" 'option' {{}}

| ��"constant" 'option' {{}}

| ��"payable" 'option' {{}}

;

I studied the JavaParser and I do not get why my version does not work��

modifiers_opt

:

| modifiers��

;

modifiers��

: modifier 'modifier'

| modifiers modifier 'modifier'

;

modifier��

: "public" 'token' {{Modifier}}

| "protected" 'token' {{Modifier}}

| "private" 'token' {{Modifier}}

| "static" 'token' {{Modifier}}

;

Thanks in advance. I could have try to do it in petitParser but I want to have a real experience with Smacc.��
