-- Implements the parsing of project files into a tree
with Prj.Tree; use Prj.Tree;
package Prj.Part is
procedure Parse
(In_Tree : Project_Node_Tree_Ref;
Project : out Project_Node_Id;
Project_File_Name : String;
Always_Errout_Finalize : Boolean;
Packages_To_Check : String_List_Access := All_Packages;
Store_Comments : Boolean := False);
-- Parse project file and all its imported project files and create a tree.
-- Return the node for the project (or Empty_Node if parsing failed). If
-- Always_Errout_Finalize is True, Errout.Finalize is called in all cases,
-- Otherwise, Errout.Finalize is only called if there are errors (but not
-- if there are only warnings). Packages_To_Check indicates the packages
-- where any unknown attribute produces an error. For other packages, an
-- unknown attribute produces a warning. When Store_Comments is True,
-- comments are stored in the parse tree.
type Extension_Origin is (None, Extending_Simple, Extending_All);
-- Type of parameter From_Extended for procedures Parse_Single_Project and
-- Post_Parse_Context_Clause. Extending_All means that we are parsing the
-- tree rooted at an extending all project.

Depth : Natural);
-- Parse a project file.
-- Recursive procedure: it calls itself for imported and extended
-- projects. When From_Extended is not None, if the project has already
-- been parsed and is an extended project A, return the ultimate
-- (not extended) project that extends A. When In_Limited is True,
-- the importing path includes at least one "limited with".
-- When parsing configuration projects, do not allow a depth > 1.
