It also -- contains the auxiliary routines used to record data from the pragmas. -- Note: the reason we split this into a child unit is that the routines -- for unit name translation have a significant number of additional -- dependencies, including osint, and hence sdefault. There are a number -- of tools that use utility subprograms in the Fname parent, but do not -- need the functionality in this child package (and certainly do not want -- to deal with the extra dependencies). with Casing; use Casing; with Types; use Types; package Fname.UF is ----------------- -- Subprograms -- ----------------- type Expected_Unit_Type is (Expect_Body, Expect_Spec, Unknown); -- Return value from Get_Expected_Unit_Type function Get_Expected_Unit_Type (Fname : File_Name_Type) return Expected_Unit_Type; -- If possible, determine whether the given file name corresponds to a unit -- that is a spec or body (e.g. by examining the extension). If this cannot -- be determined with the file naming conventions in use, then the returned -- value is set to Unknown. function Get_File_Name (Uname : Unit_Name_Type; Subunit : Boolean; May_Fail : Boolean := False) return File_Name_Type; -- This function returns the file name that corresponds to a given unit -- name, Uname. The Subunit parameter is set True for subunits, and false -- for all other kinds of units. The caller must ensure that the unit name -- meets the requirements given in package Uname. -- -- When May_Fail is True, if the file cannot be found, this function -- returns No_File. When it is False, if the file cannot be found, -- a file name compatible with one pattern Source_File_Name pragma is -- returned. function Get_Unit_Index (Uname : Unit_Name_Type) return Nat; -- If there is a specific Source_File_Name pragma for this unit, then -- return the corresponding unit index value. Return 0 if no index given. procedure Initialize; -- Initialize internal tables.

The unit name here is not encoded as a Unit_Name_Type, but is -- rather just a normal form name in lower case, e.g. "xyz.def". procedure Set_File_Name (U : Unit_Name_Type; F : File_Name_Type; Index : Nat); -- Make association between given unit name, U, and the given file name, -- F.

Pat is this pattern string, -- which contains an asterisk to correspond to the unit.
