Special insertion characters can also -- appear which cause the error message circuit to modify the given -- string as follows: -- Insertion character % (Percent: insert file name from Names table) -- The character % is replaced by the text for the file name specified -- by the Name_Id value stored in Error_Msg_Name_1. The name is always -- enclosed in quotes. A second % may appear in a single message in -- which case it is similarly replaced by the name which is specified -- by the Name_Id value stored in Error_Msg_Name_2. -- Insertion character & (Ampersand: insert unit name from Names table) -- The character & is replaced by the text for the unit name specified -- by the Name_Id value stored in Error_Msg_Name_1. The name is always -- enclosed in quotes. A second & may appear in a single message in -- which case it is similarly replaced by the name which is specified -- by the Name_Id value stored in Error_Msg_Name_2. -- Insertion character # (Pound: insert non-negative number in decimal) -- The character # is replaced by the contents of Error_Msg_Nat_1 -- converted into an unsigned decimal string. A second # may appear -- in a single message, in which case it is similarly replaced by -- the value stored in Error_Msg_Nat_2. -- Insertion character ? (Question mark: warning message) -- The character ?, which must be the first character in the message -- string, signals a warning message instead of an error message. ----------------------------------------------------- -- Global Values Used for Error Message Insertions -- ----------------------------------------------------- -- The following global variables are essentially additional parameters -- passed to the error message routine for insertion sequences described -- above. The reason these are passed globally is that the insertion -- mechanism is essentially an untyped one in which the appropriate -- variables are set dependingon the specific insertion characters used. Error_Msg_Name_1 : Name_Id; Error_Msg_Name_2 : Name_Id; -- Name_Id values for % insertion characters in message Error_Msg_Nat_1 : Nat; Error_Msg_Nat_2 : Nat; -- Integer values for # insertion characters in message ------------------------------ -- Error Output Subprograms -- ------------------------------ procedure Error_Msg (Msg : String); -- Output specified error message to standard error or standard output -- as governed by the brief and verbose switches, and update error -- counts appropriately procedure Error_Msg_Info (Msg : String); -- Output information line. Indentical in effect to Error_Msg, except -- that the prefix is info: instead of error: and the error count is -- not incremented. The prefix may be suppressed by setting the global -- variable Info_Prefix_Suppress to True. procedure Error_Msg_Output (Msg : String; Info : Boolean); -- Output given message, with insertions, to current message output file. -- The second argument is True for an info message, false for a normal -- warning or error message. Normally this is not called directly, but -- rather only by Error_Msg or Error_Msg_Info. It is called directly -- when the caller must control whether the output goes to stderr or -- stdout (Error_Msg_Output always goes to the current output file). procedure Finalize_Binderr; -- Finalize error output for one file procedure Initialize_Binderr; -- Initialize error output for one file end Binderr;
