-- This package is the Project File Pretty Printer.
-- It is used to output a project file from a project file tree.
-- It is used by gnatname to update or create project files.
-- It is also used GLIDE2 to display project file trees.
-- It can also be used for debugging purposes for tools that create project
-- file trees.

-- The following access to procedure types are used
-- to redirect output when calling Pretty_Print.
type Write_Char_Ap is access procedure (C : Character);

-- Output a project file, using either the default output
-- routines, or the ones specified by W_Char, W_Eol and W_Str.
--
-- Increment is the number of spaces for each indentation level.
--
-- W_Char, W_Eol and W_Str can be used to change the default output
-- procedures. The default values force the output to Standard_Output.
--
-- If Eliminate_Empty_Case_Constructions is True, then case constructions
-- and case items that do not include any declarations will not be output.
--
-- If Minimize_Empty_Lines is True, empty lines will be output only
-- after the last with clause, after the line declaring the project name,
-- after the last declarative item of the project and before each
-- package declaration. Otherwise, more empty lines are output.

procedure Output_Statistics;
-- This procedure can be used after one or more calls to Pretty_Print
-- to display what Project_Node_Kinds have not been exercised by the
-- call(s) to Pretty_Print. It is used only for testing purposes.
