+-- This generic package collects the routines used for style checking, as
+-- activated by the relevant command line option. These are gathered in
+-- a separate package so that they can more easily be customized. Calls
+-- to these subprograms are only made if Opt.Style_Check is set True.
+-- Styleg does not depends on the GNAT tree (Atree, Sinfo, ...).
+
+-- For the compiler, there is also a child package Styleg.C that depends
+-- on the GNAT tree.

+ with procedure Error_Msg (Msg : String; Flag_Location : Source_Ptr);

+ procedure Check_Abs_Not;
+ -- Called after scanning an ABS or NOT operator to check spacing
+
+ procedure Check_Apostrophe;
+ -- Called after scanning an apostrophe to check spacing
+
+ procedure Check_Arrow;
+ -- Called after scanning out an arrow to check spacing
+
+ procedure Check_Attribute_Name (Reserved : Boolean);
+ -- The current token is an attribute designator. Check that it
+ -- is capitalized in an appropriate manner. Reserved is set if
+ -- the attribute designator is a reserved word (access, digits,
+ -- delta or range) to allow differing rules for the two cases.
+
+ procedure Check_Box;
+ -- Called after scanning out a box to check spacing
+
+ procedure Check_Binary_Operator;
+ -- Called after scanning out a binary operator other than a plus, minus
+ -- or exponentiation operator. Intended for checking spacing rules.
+
+ procedure Check_Exponentiation_Operator;
+ -- Called after scanning out an exponentiation operator. Intended for
+ -- checking spacing rules.
+
+ procedure Check_Colon;
+ -- Called after scanning out colon to check spacing
+
+ procedure Check_Colon_Equal;
+ -- Called after scanning out colon equal to check spacing
+
+ procedure Check_Comma;
+ -- Called after scanning out comma to check spacing
+
+ procedure Check_Comment;
+ -- Called with Scan_Ptr pointing to the first minus sign of a comment.
+ -- Intended for checking any specific rules for comment placement/format.
+
+ procedure Check_Dot_Dot;
+ -- Called after scanning out dot dot to check spacing
+
+ procedure Check_EOF;
+ -- Called after scanning out EOF mark
+
+ procedure Check_HT;
+ -- Called with Scan_Ptr pointing to a horizontal tab character
+
+ procedure Check_Indentation;
+ -- Called at the start of a new statement or declaration, with Token_Ptr
+ -- pointing to the first token of the statement or declaration. The check
+ -- is that the starting column is appropriate to the indentation rules if
+ -- Token_Ptr is the first token on the line.
+
+ procedure Check_Left_Paren;
+ -- Called after scanning out a left parenthesis to check spacing
+
+ procedure Check_Line_Max_Length (Len : Int);
+ -- Called with Scan_Ptr pointing to the first line terminator character
+ -- terminating the current line. Used to check for appropriate line length.
+ -- The parameter Len is the length of the current line.
+
+ procedure Check_Line_Terminator (Len : Int);
+ -- Called with Scan_Ptr pointing to the first line terminator terminating
+ -- the current line, used to check for appropriate line terminator usage.
+ -- The parameter Len is the length of the current line.
+
+ procedure Check_Pragma_Name;
+ -- The current token is a pragma identifier. Check that it is spelled
+ -- properly (i.e. with an appropriate casing convention).
+
+ procedure Check_Right_Paren;
+ -- Called after scanning out a right parenthesis to check spacing
+
+ procedure Check_Semicolon;
+ -- Called after scanning out a semicolon to check spacing
+
+ procedure Check_Then (If_Loc : Source_Ptr);
+ -- Called to check that THEN and IF keywords are appropriately positioned.
+ -- The parameters show the first characters of the two keywords. This
+ -- procedure is called only if THEN appears at the start of a line with
+ -- Token_Ptr pointing to the THEN keyword.
+
+ procedure Check_Unary_Plus_Or_Minus;
+ -- Called after scanning a unary plus or minus to check spacing
+
+ procedure Check_Vertical_Bar;
+ -- Called after scanning a vertical bar to check spacing
+
+ procedure Check_Xtra_Parens (Loc : Source_Ptr);
+ -- Called after scanning a conditional expression that has at least one
+ -- level of parentheses around the entire expression.
+
+ function Mode_In_Check return Boolean;
+ pragma Inline (Mode_In_Check);
+ -- Determines whether style checking is active and the Mode_In_Check is
+ -- set, forbidding the explicit use of mode IN.
+
+ procedure No_End_Name (Name : Node_Id);
+ -- Called if an END is encountered where a name is allowed but not present.
+ -- The parameter is the node whose name is the name that is permitted in
+ -- the END line, and the scan pointer is positioned so that if an error
+ -- message is to be generated in this situation, it should be generated
+ -- using Error_Msg_SP.
+
+ procedure No_Exit_Name (Name : Node_Id);
+ -- Called when exiting a named loop, but a name is not present on the EXIT.
+ -- The parameter is the node whose name should have followed EXIT, and the
+ -- scan pointer is positioned so that if an error message is to be
+ -- generated, it should be generated using Error_Msg_SP.
+
+ procedure Non_Lower_Case_Keyword;
+ -- Called if a reserved keyword is scanned which is not spelled in all
+ -- lower case letters. On entry Token_Ptr points to the keyword token.
+ -- This is not used for keywords appearing as attribute designators,
+ -- where instead Check_Attribute_Name (True) is called.
+
+ function RM_Column_Check return Boolean;
+ pragma Inline (RM_Column_Check);
+ -- Determines whether style checking is active and the RM column check
+ -- mode is set requiring checking of RM format layout.
