45 -- Error Message Text and Message Insertion Characters --
46 ---------------------------------------------------------
47
48 -- Error message text strings are composed of letters, digits and the
49 -- special characters space, comma, period, colon and semicolon,
50 -- apostrophe and parentheses. Special insertion characters can also
51 -- appear which cause the error message circuit to modify the given
52 -- string as follows:
53
54 -- Insertion character { (Left brace: insert file name from Names table)
55 -- The character { is replaced by the text for the file name specified
56 -- by the File_Name_Type value stored in Error_Msg_File_1. The name is
57 -- always enclosed in quotes. A second { may appear in a single message
58 -- in which case it is similarly replaced by the name which is
59 -- specified by the File_Name_Type value stored in Error_Msg_File_2.
60
61 -- Insertion character $ (Dollar: insert unit name from Names table)
62 -- The character $ is replaced by the text for the unit name specified
63 -- by the Name_Id value stored in Error_Msg_Unit_1. The name is always
64 -- enclosed in quotes. A second $ may appear in a single message in
65 -- which case it is similarly replaced by the name which is specified
66 -- by the Name_Id value stored in Error_Msg_Unit_2.
67
68 -- Insertion character # (Pound: insert non-negative number in decimal)
69 -- The character # is replaced by the contents of Error_Msg_Nat_1
70 -- converted into an unsigned decimal string. A second # may appear
71 -- in a single message, in which case it is similarly replaced by
72 -- the value stored in Error_Msg_Nat_2.
73
74 -- Insertion character ? (Question mark: warning message)
75 -- The character ?, which must be the first character in the message
76 -- string, signals a warning message instead of an error message.
77
78 -----------------------------------------------------
79 -- Global Values Used for Error Message Insertions --
80 -----------------------------------------------------
81
82 -- The following global variables are essentially additional parameters
83 -- passed to the error message routine for insertion sequences described
84 -- above. The reason these are passed globally is that the insertion
85 -- mechanism is essentially an untyped one in which the appropriate
86 -- variables are set depending on the specific insertion characters used.
87
88 Error_Msg_Name_1 : Name_Id;
89 -- Name_Id value for % insertion characters in message
90
91 Error_Msg_File_1 : File_Name_Type;
92 Error_Msg_File_2 : File_Name_Type;
93 -- Name_Id values for { insertion characters in message
94
95 Error_Msg_Unit_1 : Unit_Name_Type;
96 Error_Msg_Unit_2 : Unit_Name_Type;
97 -- Name_Id values for $ insertion characters in message
98
99 Error_Msg_Nat_1 : Nat;
100 Error_Msg_Nat_2 : Nat;
101 -- Integer values for # insertion characters in message

107 procedure Error_Msg (Msg : String);
108 -- Output specified error message to standard error or standard output
109 -- as governed by the brief and verbose switches, and update error
110 -- counts appropriately
111
112 procedure Error_Msg_Info (Msg : String);
113 -- Output information line. Indentical in effect to Error_Msg, except
114 -- that the prefix is info: instead of error: and the error count is
115 -- not incremented. The prefix may be suppressed by setting the global
116 -- variable Info_Prefix_Suppress to True.
117
118 procedure Error_Msg_Output (Msg : String; Info : Boolean);
119 -- Output given message, with insertions, to current message output file.
120 -- The second argument is True for an info message, false for a normal
121 -- warning or error message. Normally this is not called directly, but
122 -- rather only by Error_Msg or Error_Msg_Info. It is called directly
123 -- when the caller must control whether the output goes to stderr or
124 -- stdout (Error_Msg_Output always goes to the current output file).
125
126 procedure Finalize_Binderr;
