-- General wrapper for the parsing of project files
with Prj.Tree;
package Prj.Pars is
procedure Set_Verbosity (To : Verbosity);
-- Set the verbosity when parsing the project files
procedure Parse
(In_Tree : Project_Tree_Ref;
Project : out Project_Id;
Project_File_Name : String;
Packages_To_Check : String_List_Access;
Reset_Tree : Boolean := True;
In_Node_Tree : Prj.Tree.Project_Node_Tree_Ref := null;
Env : in out Prj.Tree.Environment);
-- Parse and process a project files and all its imported project files, in
-- the project tree In_Tree.
--
-- All the project files are parsed (through Prj.Tree) to create a tree in
-- memory. That tree is then processed (through Prj.Proc) to create a
-- expanded representation of the tree based on the current external
-- references. This function is only a convenient wrapper over other
-- services provided in the Prj.* package hierarchy.
--
-- If parsing is successful, Project is the project ID of the root project
-- file; otherwise, Project_Id is set to No_Project. Project_Node_Tree is
-- set to the tree (unprocessed) representation of the project file. This
-- tree is permanently correct, whereas Project will need to be recomputed
-- if the external references change.
--
-- Packages_To_Check indicates the packages where any unknown attribute
-- produces an error. For other packages, an unknown attribute produces a
-- warning.
--
-- When Reset_Tree is True, all the project data are removed from the
-- project table before processing.
--
-- In_Node_Tree (if given) must have been Initialized. The main reason to
-- pass an existing tree, is to pass the external references that will then
-- be used to process the tree.
