-- This package implements parsing of string expressions in project files
with Prj.Tree; use Prj.Tree;

procedure Parse_String_Type_List
(In_Tree : Project_Node_Tree_Ref;
First_String : out Project_Node_Id;
Flags : Processing_Flags);
-- 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
(In_Tree : Project_Node_Tree_Ref;
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
(Check_All_Labels : Boolean;
Case_Location : Source_Ptr;
Flags : Processing_Flags);
-- 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. When When_Others is False and we are not in
-- quiet output, a warning is emitted for each value of the case variable
-- string type that has not been specified.
procedure Parse_Choice_List
(In_Tree : Project_Node_Tree_Ref;
First_Choice : out Project_Node_Id;
Flags : Processing_Flags);
-- 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

(In_Tree : Project_Node_Tree_Ref;
Expression : out Project_Node_Id;
Current_Project : Project_Node_Id;
Current_Package : Project_Node_Id;
Optional_Index : Boolean;
Flags : Processing_Flags);
-- 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
(In_Tree : Project_Node_Tree_Ref;
Variable : out Project_Node_Id;
Current_Project : Project_Node_Id;
Current_Package : Project_Node_Id;
Flags : Processing_Flags);
-- Parse 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 apostrophe, followed by the attribute simple name.
