| -- This package contains the routines to output error messages for the binder |
| -- and also the routines for handling fatal error conditions in the binder. |
| |
| with Types; use Types; |
| |
| package Binderr is |
| |
| Errors_Detected : Int; |
| -- Number of errors detected so far |
| |
| Warnings_Detected : Int; |
| -- Number of warnings detected |
| |
| Info_Prefix_Suppress : Boolean := False; |
| -- If set to True, the normal "info: " header before messages generated |
| -- by Error_Msg_Info will be omitted. |
| |
| --------------------------------------------------------- |
| -- Error Message Text and Message Insertion Characters -- |
| --------------------------------------------------------- |
| |
| -- Error message text strings are composed of letters, digits and the |
| -- special characters space, comma, period, colon and semicolon, |
| -- apostrophe and parentheses. 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; |
