The default values shown here correspond to no style - -- checking. If any of these values is set to a non-default value, - -- then Opt.Style_Check is set True to active calls to this package. - - -- The actual mechanism for setting these switches to other than - -- default values is via the Set_Style_Check_Option procedure or - -- through a call to Set_Default_Style_Check_Options. They should - -- not be set directly in any other manner. - - Style_Check_Attribute_Casing : Boolean := False; - -- This can be set True by using the -gnatg or -gnatya switches. If - -- it is True, then attribute names (including keywords such as - -- digits used as attribute names) must be in mixed case. - - Style_Check_Blanks_At_End : Boolean := False; - -- This can be set True by using the -gnatg or -gnatyb switches. If - -- it is True, then spaces at the end of lines are not permitted. - - Style_Check_Blank_Lines : Boolean := False; - -- This can be set True by using the -gnatg or -gnatyu switches. If - -- it is True, then multiple blank lines are not permitted, and there - -- may not be a blank line at the end of the file. - - Style_Check_Comments : Boolean := False; - -- This can be set True by using the -gnatg or -gnatyc switches. If - -- it is True, then comments are style checked as follows: - -- - -- All comments must be at the start of the line, or the first - -- minus must be preceded by at least one space. - -- - -- For a comment that is not at the start of a line, the only - -- requirement is that a space follow the comment characters. - -- - -- For a coment that is at the start of the line, one of the - -- following conditions must hold: - -- - -- The comment characters are the only non-blank characters on the line - -- - -- The comment characters are followed by an exclamation point (the - -- sequence --! is used by gnatprep for marking deleted lines). - -- - -- The comment characters are followed by two space characters - -- - -- The line consists entirely of minus signs - -- - -- The comment characters are followed by a single space, and the - -- last two characters on the line are also comment characters. - -- - -- Note: the reason for the last two conditions is to allow "boxed" - -- comments where only a single space separates the comment characters. - - Style_Check_DOS_Line_Terminator : Boolean := False; - -- This can be set true by using the -gnatg or -gnatyd switches. If - -- it is True, then the line terminator must be a single LF, without an - -- associated CR (e.g. DOS line terminator sequence CR/LF not allowed). - - Style_Check_End_Labels : Boolean := False; - -- This can be set True by using the -gnatg or -gnatye switches. If - -- it is True, then optional END labels must always be present. - - Style_Check_Form_Feeds : Boolean := False; - -- This can be set True by using the -gnatg or -gnatyf switches. If - -- it is True, then form feeds and vertical tabs are not allowed in - -- the source text. - - Style_Check_Horizontal_Tabs : Boolean := False; - -- This can be set True by using the -gnatg or -gnatyh switches. If - -- it is True, then horizontal tabs are not allowed in source text. - - Style_Check_If_Then_Layout : Boolean := False; - -- This can be set True by using the -gnatg or -gnatyi switches. If - -- it is True, then a THEN keyword may not appear on the line that - -- immediately follows the line containing the corresponding IF. - -- - -- This permits one of two styles for IF-THEN layout. Either the - -- IF and THEN keywords are on the same line, where the condition - -- is short enough, or the conditions are continued over to the - -- lines following the IF and the THEN stands on its own. For - -- example: - -- - -- if X > Y then - -- - -- if X > Y - -- and then Y < Z - -- then - -- - -- are allowed, but - -- - -- if X > Y - -- then - -- - -- is not allowed. - - Style_Check_Indentation : Column_Number range 0 .. 9 := 0; - -- This can be set non-zero by using the -gnatg or -gnatyn (n a digit) - -- switches. If it is non-zero it activates indentation checking with - -- the indicated indentation value. A value of zero turns off checking. - -- The requirement is that any new statement, line comment, declaration - -- or keyword such as END, start on a column that is a multiple of the - -- indentiation value. - - Style_Check_Keyword_Casing : Boolean := False; - -- This can be set True by using the -gnatg or -gnatyk switches. If - -- it is True, then keywords are required to be in all lower case. - -- This rule does not apply to keywords such as digits appearing as - -- an attribute name. - - Style_Check_Max_Line_Length : Boolean := False; - -- This can be set True by using the -gnatg or -gnatym/M switches. - -- If it is True, it activates checking for a maximum line length of - -- Style_Max_Line_Length characters. - - Style_Check_Max_Nesting_Level : Boolean := False; - -- This can be set True by using -gnatyLnnn with a value other than - -- zero (a value of zero resets it to False). If True, it activates - -- checking the maximum nesting level against Style_Max_Nesting_Level. - - Style_Check_Mode_In : Boolean := False; - -- This can be set True by using -gnatyI. If True, it activates checking - -- that mode IN is not used on its own (since it is the default). - - Style_Check_Order_Subprograms : Boolean := False; - -- This can be set True by using the -gnatg or -gnatyo switch. If it - -- is True, then names of subprogram bodies must be in alphabetical - -- order (not taking casing into account). - - Style_Check_Pragma_Casing : Boolean := False; - -- This can be set True by using the -gnatg or -gnatyp switches. If - -- it is True, then pragma names must use mixed case. - - Style_Check_Layout : Boolean := False; - -- This can be set True by using the -gnatg or -gnatyl switches. If - -- it is True, it activates checks that constructs are indented as - -- suggested by the examples in the RM syntax, e.g. that the ELSE - -- keyword must line up with the IF keyword. - - Style_Check_References : Boolean := False; - -- This can be set True by using the -gnatg or -gnatyr switches. If - -- it is True, then all references to declared identifiers are - -- checked. The requirement is that casing of the reference be the - -- same as the casing of the corresponding declaration. - - Style_Check_Specs : Boolean := False; - -- This can be set True by using the -gnatg or -gnatys switches. If - -- it is True, then separate specs are required to be present for - -- all procedures except parameterless library level procedures. - -- The exception means that typical main programs do not require - -- separate specs. - - Style_Check_Standard : Boolean := False; - -- This can be set True by using the -gnatg or -gnatyn switches. If - -- it is True, then any references to names in Standard have to be - -- in mixed case mode (e.g. Integer, Boolean). - - Style_Check_Tokens : Boolean := False; - -- This can be set True by using the -gnatg or -gnatyt switches. If - -- it is True, then the style check that requires canonical spacing - -- between various punctuation tokens as follows: - -- - -- ABS and NOT must be followed by a space - -- - -- => must be surrounded by spaces - -- - -- <> must be preceded by a space or left paren - -- - -- Binary operators other than ** must be surrounded by spaces. - -- There is no restriction on the layout of the ** binary operator. - -- - -- Colon must be surrounded by spaces - -- - -- Colon-equal (assignment) must be surrounded by spaces - -- - -- Comma must be the first non-blank character on the line, or be - -- immediately preceded by a non-blank character, and must be followed - -- by a blank. - -- - -- A space must precede a left paren following a digit or letter, - -- and a right paren must not be followed by a space (it can be - -- at the end of the line). - -- - -- A right paren must either be the first non-blank character on - -- a line, or it must be preceded by a non-blank character. - -- - -- A semicolon must not be preceded by a blank, and must not be - -- followed by a non-blank character. - -- - -- A unary plus or minus may not be followed by a space - -- - -- A vertical bar must be surrounded by spaces - -- - -- Note that a requirement that a token be preceded by a space is - -- met by placing the token at the start of the line, and similarly - -- a requirement that a token be followed by a space is met by - -- placing the token at the end of the line. Note that in the case - -- where horizontal tabs are permitted, a horizontal tab is acceptable - -- for meeting the requirement for a space. - - Style_Check_Xtra_Parens : Boolean := False; - -- This can be set True by using the -gnatg or -gnatyx switch. If true, - -- then it is not allowed to enclose entire conditional expressions - -- in parentheses (C style). - - Style_Max_Line_Length : Int := 0; - -- Value used to check maximum line length. Gets reset as a result of - -- use of -gnatym or -gnatyMnnn switches (or by use of -gnatg). This - -- value is only read if Style_Check_Max_Line_Length is True. - - Style_Max_Nesting_Level : Int := 0; - -- Value used to check maximum nesting level. Gets reset as a result - -- of use of the -gnatyLnnn switch. This value is only read if - -- Style_Check_Max_Nesting_Level is True. - - ----------------- - -- Subprograms -- - ----------------- - - procedure Set_Default_Style_Check_Options; - -- This procedure is called to set the default style checking options - -- in response to a -gnaty switch with no suboptions. - - Style_Msg_Buf : String (1 .. 80); - Style_Msg_Len : Natural; - -- Used to return - - procedure Set_Style_Check_Options - (Options : String; - OK : out Boolean; - Err_Col : out Natural); - -- This procedure is called to set the style check options that correspond - -- to the characters in the given Options string. If all options are valid, - -- they are set in an additive manner: any previous options are retained - -- unless overridden. - -- - -- If all options given are valid, then OK is True, Err_Col is set to - -- Options'Last + 1, and Style_Msg_Buf/Style_Msg_Len are unchanged. - -- - -- If an invalid character is found, then OK is False on exit, and Err_Col - -- is the index in options of the bad character. In this case Style_Msg_Len - -- is set and Style_Msg_Buf (1 .. Style_Msg_Len) has a detailed message - -- describing the error. - - procedure Set_Style_Check_Options (Options : String); - -- Like the above procedure, but used when the Options string is known to - -- be valid. This is for example appopriate for calls where the string == - -- was obtained by Save_Style_Check_Options. - - procedure Reset_Style_Check_Options; - -- Sets all style check options to off - - subtype Style_Check_Options is String (1 .. 64); - -- Long enough string to hold all options from Save call below - - procedure Save_Style_Check_Options (Options : out Style_Check_Options); - -- Sets Options to represent current selection of options. This - -- set can be restored by first calling Reset_Style_Check_Options, - -- and then calling Set_Style_Check_Options with the Options string. - -end Stylesw; |
