-
- procedure Parse_String_Type_List (First_String : out Project_Node_Id);
- -- Get the list of literal strings that are allowed for a typed string.
- -- On entry, the current token is the first literal string following
- -- a left parenthesis in a string type declaration such as:
- -- type Toto is ("string_1", "string_2", "string_3");
- -- On exit, the current token is the right parenthesis.
- -- The parameter First_String is a node that contained the first
- -- literal string of the string type, linked with the following
- -- literal strings.
- --
- -- Report an error if
- -- - a literal string is not found at the beginning of the list
- -- or after a comma
- -- - two literal strings in the list are equal
-
- procedure Start_New_Case_Construction (String_Type : Project_Node_Id);
- -- This procedure is called at the beginning of a case construction
- -- The parameter String_Type is the node for the string type
- -- of the case label variable.
- -- The different literal strings of the string type are stored
- -- into a table to be checked against the case labels of the
- -- case construction.
-
- procedure End_Case_Construction;
- -- This procedure is called at the end of a case construction
- -- to remove the case labels and to restore the previous state.
- -- In particular, in the case of nested case constructions,
- -- the case labels of the enclosing case construction are restored.
-
- procedure Parse_Choice_List
- (First_Choice : out Project_Node_Id);
- -- Get the label for a choice list.
- -- Report an error if
- -- - a case label is not a literal string
- -- - a case label is not in the typed string list
- -- - the same case label is repeated in the same case construction
-
- procedure Parse_Expression
- (Expression : out Project_Node_Id;
- Current_Project : Project_Node_Id;
- Current_Package : Project_Node_Id);
- -- Parse a simple string expression or a string list expression.
- -- Current_Project is the node of the project file being parsed.
- -- Current_Package is the node of the package being parsed,
- -- or Empty_Node when we are at the project level (not in a package).
- -- On exit, Expression is the node of the expression that has
- -- been parsed.
-
- procedure Parse_Variable_Reference
- (Variable : out Project_Node_Id;
- Current_Project : Project_Node_Id;
- Current_Package : Project_Node_Id);
- -- Parse a variable or attribute reference.
- -- Used internally (in expressions) and for case variables (in Prj.Dect).
- -- Current_Package is the node of the package being parsed,
- -- or Empty_Node when we are at the project level (not in a package).
- -- On exit, Variable is the node of the variable or attribute reference.
- -- A variable reference is made of one to three simple names.
- -- An attribute reference is made of one or two simple names,
- -- followed by an apostroph, followed by the attribute simple name.
