| |
| -- This child package contains a routine to read and process Source_File_Name |
| -- pragmas from the gnat.adc file in the current directory. In order to use |
| -- the routines in package Fname.UF, it is required that Source_File_Name |
| -- pragmas be processed. There are two places where such processing takes |
| -- place: |
| |
| -- The compiler front end (par-prag.adb), which is the general circuit |
| -- for processing all pragmas, including Source_File_Name. |
| |
| -- The stand alone routine in this unit, which is convenient to use |
| -- from tools that do not want to include the compiler front end. |
| |
| -- Note that this unit does depend on several of the compiler front-end |
| -- sources, including osint. If it is necessary to scan source file name |
| -- pragmas with less dependence on such sources, look at unit SFN_Scan. |
| |
| package Fname.SF is |
| |
| procedure Read_Source_File_Name_Pragmas; |
| -- This procedure is called to read the gnat.adc file and process any |
| -- Source_File_Name pragmas contained in this file. All other pragmas |
| -- are ignored. The result is appropriate calls to routines in the |
| -- package Fname.UF to register the pragmas so that subsequent calls |
| -- to Get_File_Name work correctly. |
| -- |
| -- Note: The caller must have made an appropriate call to the |
| -- Osint.Initialize routine to initialize Osint before calling |
| -- this procedure. |
| -- |
| -- If a syntax error is detected while scanning the gnat.adc file, |
| -- then the exception SFN_Scan.Syntax_Error_In_GNAT_ADC is raised |
| -- and SFN_Scan.Cursor contains the approximate index relative to |
| -- the start of the gnat.adc file of the error. |
