The EBNF grammar will be fixed in the next release of sudo. |
In the EBNF for the Default keyword in the sudoers manpage is found the following BNF: Default_Type ::= 'Defaults' || 'Defaults' '@' Host || 'Defaults' ':' User || 'Defaults' '>' RunasUser Default_Entry ::= Default_Type Parameter_List Parameter ::= Parameter '=' Value || Parameter '+=' Value || Parameter '-=' Value || '!'* Parameter || The 'Default_Entry' line references a Parameter_List, but Parameter_List is not defined anywhere in the manpage. The Suggested BNF should (possibly) look like this: Default_Type ::= 'Defaults' || 'Defaults' '@' Host || 'Defaults' ':' User || 'Defaults' '>' RunasUser Default_Entry ::= Default_Type Parameter_List Parameter ::= Parameter '=' Value || Parameter '+=' Value || Parameter '-=' Value || '!'* Parameter || Parameter_List ::= Parameter | Parameter ',' Parameter_List Also, there is an apparent descrepency of usage for the 'or' pipe in the BNF found with the Default parameter versus other parameters (i.e. User_List). In Default, double-pipes are used to specify 'or', where everyplace else uses the single-pipe. I suggest the Default parameter contains the improper 'or' pipes because of this line near the top of the manpage in the 'Quick Guide to EBNF' section: symbol ::= definition | alternate1 | alternate2 ...
