|
|
|
-- This package provides a stand alone capability for scanning a gnat.adc
|
|
-- file for Source_File_Name pragmas. This is for use in tools other than
|
|
-- the compiler, which want to scan source file name pragmas without the
|
|
-- overhead of the full compiler scanner and parser.
|
|
|
|
-- Note that neither the package spec, nor the package body, of this
|
|
-- unit contains any with statements at all. This is a completely
|
|
-- independent package, suitable for incorporation into tools that do
|
|
-- not access any other units in the GNAT compiler or tools sources.
|
|
|
|
-- This package is NOT task safe, so multiple tasks that may call the
|
|
-- Scan_SFN_Pragmas procedure at the same time are responsible for
|
|
-- avoiding such multiple calls by appropriate synchronization.
|
|
|
|
package SFN_Scan is
|
|
|
|
-- The call to SFN_Scan passes pointers to two procedures that are
|
|
-- used to store the results of scanning any Source_File_Name pragmas
|
|
-- that are encountered. The following access types define the form
|
|
-- of these procedures:
|
|
|
|
type Set_File_Name_Ptr is access
|
|
procedure
|
|
(Typ : Character;
|
|
U : String;
|
|
F : String;
|
|
Index : Natural);
|
|
-- The procedure with this profile is called when a Source_File_Name
|
|
-- pragma of the form having a unit name parameter. Typ is 'b' for
|
|
-- a body file name, and 's' for a spec file name. U is a string that
|
|
-- contains the unit name, exactly as it appeared in the source file,
|
|
-- and F is the file taken from the second parameter. Index is taken
|
|
-- from the third parameter, or is set to zero if no third parameter.
|
|
|
|
type Set_File_Name_Pattern_Ptr is access
|
|
procedure (Pat : String; Typ : Character; Dot : String; Cas : Character);
|
|
-- This is called to process a Source_File_Name pragma whose first
|
|
-- argument is a file pattern. Pat is this pattern string, which
|
|
-- contains an asterisk to correspond to the unit. Typ is one of
|
|
-- ('b'/'s'/'u') for body/spec/subunit, Dot is the separator string
|
|
-- for child/subunit names (default is "."), and Cas is one of
|
|
-- ('l'/'u'/'m') indicating the required case for the file name.
|
|
-- The default setting for Cas is 'l' if no parameter is present.
|
|
|
|
Cursor : Natural;
|
|
-- Used to record the cursor value if a syntax error is found
|
|
|
|
Syntax_Error_In_GNAT_ADC : exception;
|
|
-- Exception raised if a syntax error is found
|
|
|
|
procedure Scan_SFN_Pragmas
|
|
(Source : String;
|
|
SFN_Ptr : Set_File_Name_Ptr;
|
|
SFNP_Ptr : Set_File_Name_Pattern_Ptr);
|
|
-- This is the procedure called to scan a gnat.adc file. The Source
|
|
-- parameter points to the full text of the file, with normal line end
|
|
-- characters, in the format normally read by the compiler. The two
|
|
-- parameters SFN_Ptr and SFNP_Ptr point to procedures that will be
|
|
-- called to register Source_File_Name pragmas as they are found.
|
|
--
|
|
-- If a syntax error is found, then Syntax_Error_In_GNAT_ADC is raised,
|
|
-- and the location SFN_Scan.Cursor contains the approximate index of
|
|
-- the error in the source string.
|
|
--
|
|
-- The scan assumes that it is dealing with a valid gnat.adc file,
|
|
-- that includes only pragmas and comments. It does not do a full
|
|
-- syntax correctness scan by any means, but if it does find anything
|
|
-- that it can tell is wrong it will immediately raise the exception
|
|
-- to indicate the approximate location of the error
|
