66 -- Information about an imported project, to be put in table Withs below
75 -- Table used to store temporarily paths and locations of imported
76 -- projects. These imported projects will be effectively parsed later: just
77 -- before parsing the current project for the non limited withed projects,
78 -- after getting its name; after complete parsing of the current project
79 -- for the limited withed projects.
95 -- This table is used to detect circular dependencies
96 -- for imported and extended projects and to get the project ids of
97 -- limited imported projects when there is a circularity with at least
98 -- one limited imported project file.
107 -- Hash table to store the node ids of projects for which a virtual
108 -- extending project need to be created. The corresponding value is the
109 -- head of a list of WITH clauses corresponding to the context of the
110 -- enclosing EXTEND ALL projects. Note: Default_Element is Project_Node_
111 -- High_Bound because we want Empty_Node to be a possible value.
120 -- Hash table to store the project process when looking for project that
121 -- need to have a virtual extending project, to avoid processing the same
122 -- project twice.

146 -- extending-all project.

154 procedure Check_Import_Aggregate
158 -- Check that a non aggregate project does not import an aggregate project
160 procedure Create_Virtual_Extending_Project
165 -- Create a virtual extending project of For_Project. Main_Project is
166 -- the extending all project. Extension_Withs is the head of a WITH clause
167 -- list to be added to the created virtual project.
168 --
169 -- The String_Value_Of is not set for the automatically added with
170 -- clause and keeps the default value of No_Name. This enables Prj.PP

181 -- imports may need to be virtually extended.

212 -- If Implicit_Project is True, change the Directory of the project node
213 -- to be the Current_Dir. Recursive calls to Parse_Single_Project are
214 -- always done with the default False value for Implicit_Project.
216 procedure Pre_Parse_Context_Clause
221 -- Parse the context clause of a project. Store the paths and locations of
222 -- the imported projects in table Withs. Does nothing if there is no
