17. Projects: manipulating gpr filesΒΆ

The package GNATCOLL.Projects provides an extensive interface to parse, manipulate and edit project files (.gpr files).

Although the interface is best used using the Ada05 notation, it is fully compatible with Ada95.

Here is a quick example on how to use the interface, although the spec file itself contains much more detailed information on all the subprograms related to the manipulation of project files:

pragma Ada_05;
with GNATCOLL.Projects; use GNATCOLL.Projects;
with GNATCOLL.VFS;      use GNATCOLL.VFS;

procedure Test_Project is
   Tree  : Project_Tree;
   Files : File_Array_Access;
begin
   Tree.Load (GNATCOLL.VFS.Create (+"path_to_project.gpr"));

   --  List the source files for project and all imported projects

   Files := Tree.Root_Project.Source_Files (Recursive => True);
   for F in Files'Range loop
      Put_Line ("File is: " & Files (F).Display_Full_Name);
   end loop;

   Tree.Unload;
end Test_Project;
