-
-A few words about features of the new completely rewritten LexPascal...
-
-Generally speaking LexPascal tries to support all available Delphi features (up
-to Delphi 2009 at this time), including .NET specific features.
-
-~ HIGHLIGHTING:
-
-If you enable "lexer.pascal.smart.highlighting" property, some keywords will
-only be highlighted in appropriate context. As implemented those are keywords
-related to property and DLL exports declarations (similar to how Delphi IDE
-works).
-
-For example, keywords "read" and "write" will only be highlighted if they are in
-property declaration:
-
-property MyProperty: boolean read FMyProperty write FMyProperty;
-
-~ FOLDING:
-
-Folding is supported in the following cases:
-
-- Folding of stream-like comments
-- Folding of groups of consecutive line comments
-- Folding of preprocessor blocks (the following preprocessor blocks are
-supported: IF / IFEND; IFDEF, IFNDEF, IFOPT / ENDIF and REGION / ENDREGION
-blocks), including nesting of preprocessor blocks up to 255 levels
-- Folding of code blocks on appropriate keywords (the following code blocks are
-supported: "begin, asm, record, try, case / end" blocks, class & object
-declarations and interface declarations)
-
-Remarks:
-
-- Folding of code blocks tries to handle all special cases in which folding
-should not occur. As implemented those are:
-
-1. Structure "record case / end" (there's only one "end" statement and "case" is
-ignored as fold point)
-2. Forward class declarations ("type TMyClass = class;") and object method
-declarations ("TNotifyEvent = procedure(Sender: TObject) of object;") are
-ignored as fold points
-3. Simplified complete class declarations ("type TMyClass = class(TObject);")
-are ignored as fold points
-4. Every other situation when class keyword doesn't actually start class
-declaration ("class procedure", "class function", "class of", "class var",
-"class property" and "class operator")
-
-- Folding of code blocks inside preprocessor blocks is disabled (any comments
-inside them will be folded fine) because there is no guarantee that complete
-code block will be contained inside folded preprocessor block in which case
-folded code block could end prematurely at the end of preprocessor block if
-there is no closing statement inside. This was done in order to properly process
-document that may contain something like this:
-
-type
-{$IFDEF UNICODE}
- TMyClass = class(UnicodeAncestor)
-{$ELSE}
- TMyClass = class(AnsiAncestor)
-{$ENDIF}
- private
- ...
- public
- ...
- published
- ...
-end;
-
-If class declarations were folded, then the second class declaration would end
-at "$ENDIF" statement, first class statement would end at "end;" statement and
-preprocessor "$IFDEF" block would go all the way to the end of document.
-However, having in mind all this, if you want to enable folding of code blocks
-inside preprocessor blocks, you can disable folding of preprocessor blocks by
-changing "fold.preprocessor" property, in which case everything inside them
-would be folded.
-
-~ KEYWORDS:
-
-The list of keywords that can be used in pascal.properties file (up to Delphi
-2009):
-
-- Keywords: absolute abstract and array as asm assembler automated begin case
-cdecl class const constructor deprecated destructor dispid dispinterface div do
-downto dynamic else end except export exports external far file final
-finalization finally for forward function goto if implementation in inherited
-initialization inline interface is label library message mod near nil not object
-of on or out overload override packed pascal platform private procedure program
-property protected public published raise record register reintroduce repeat
-resourcestring safecall sealed set shl shr static stdcall strict string then
-threadvar to try type unit unsafe until uses var varargs virtual while with xor
-
-- Keywords related to the "smart highlithing" feature: add default implements
-index name nodefault read readonly remove stored write writeonly
-
-- Keywords related to Delphi packages (in addition to all above): package
-contains requires
