/*
 | 
						|
 | 
						|
A few words about features of the new completely rewritten LexPascal...
 | 
						|
 | 
						|
Generally speaking LexPascal tries to support all available Delphi features (up
 | 
						|
to Delphi XE4 at this time).
 | 
						|
 | 
						|
~ 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")
 | 
						|
5. Forward (disp)interface declarations ("type IMyInterface = interface;") are
 | 
						|
ignored as fold points
 | 
						|
 | 
						|
- 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
 | 
						|
XE4):
 | 
						|
 | 
						|
- Keywords: absolute abstract and array as asm assembler automated begin case
 | 
						|
cdecl class const constructor delayed deprecated destructor dispid dispinterface
 | 
						|
div do downto dynamic else end except experimental export exports external far
 | 
						|
file final finalization finally for forward function goto helper if
 | 
						|
implementation in inherited initialization inline interface is label library
 | 
						|
message mod near nil not object of on operator or out overload override packed
 | 
						|
pascal platform private procedure program property protected public published
 | 
						|
raise record reference 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 winapi 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
