--- This package contains the routines to output error messages and the scanner
--- for the project files. It replaces Errout and Scn. It is not dependent on
--- the GNAT tree packages (Atree, Sinfo, ...). It uses exactly the same global
--- variables as Errout, located in package Err_Vars. Like Errout, it also uses
--- the common variables and routines in package Erroutc.
---
--- Parameters are set through Err_Vars.Error_Msg_File_* or
--- Err_Vars.Error_Msg_Name_*, and replaced automatically in the messages
--- ("{{" for files, "%%" for names).
---
--- However, in this package you can configure the error messages to be sent
--- to your own callback by setting Report_Error in the flags. This ensures
--- that applications can control where error messages are displayed.

-
- procedure Clear_Source_File_Table;
- -- This procedure frees memory allocated in the Source_File table (in the
- -- private part of package Sinput). It should only be used when it is
- -- guaranteed that all source files that have been loaded so far will not
- -- be accessed before being reloaded. It is intended for tools that parse
- -- several times sources, to avoid memory leaks.
-
- function Load_Project_File (Path : String) return Source_File_Index;
- -- Load the source of a project source file into memory and initialize the
- -- Scans state.
-
- procedure Reset_First;
- -- Indicate that the next project loaded should be considered as the first
- -- one, so that Sinput.Main_Source_File is set for this project file. This
- -- is to get the correct number of lines when error finalization is called.
-
- function Source_File_Is_Subunit (X : Source_File_Index) return Boolean;
- -- This function determines if a source file represents a subunit. It works
- -- by scanning for the first compilation unit token, and returning True if
- -- it is the token SEPARATE. It will return False otherwise, meaning that
- -- the file cannot possibly be a legal subunit. This function does NOT do a
- -- complete parse of the file, or build a tree. It is used in gnatmake and
- -- gprbuild to decide if a body without a spec in a project file needs to
- -- be compiled or not. Returns False if X = No_Source_File.
