12 A few words about features of the new completely rewritten LexPascal...
14 Generally speaking LexPascal tries to support all available Delphi features (up
15 to Delphi XE4 at this time).
17 ~ HIGHLIGHTING:
19 If you enable "lexer.pascal.smart.highlighting" property, some keywords will
20 only be highlighted in appropriate context. As implemented those are keywords
21 related to property and DLL exports declarations (similar to how Delphi IDE
22 works).
24 For example, keywords "read" and "write" will only be highlighted if they are in
25 property declaration:
27 property MyProperty: boolean read FMyProperty write FMyProperty;
29 ~ FOLDING:
31 Folding is supported in the following cases:
33 - Folding of stream-like comments
34 - Folding of groups of consecutive line comments
35 - Folding of preprocessor blocks (the following preprocessor blocks are
36 supported: IF / IFEND; IFDEF, IFNDEF, IFOPT / ENDIF and REGION / ENDREGION
37 blocks), including nesting of preprocessor blocks up to 255 levels
38 - Folding of code blocks on appropriate keywords (the following code blocks are
39 supported: "begin, asm, record, try, case / end" blocks, class & object
40 declarations and interface declarations)
42 Remarks:
44 - Folding of code blocks tries to handle all special cases in which folding
45 should not occur. As implemented those are:
47 1. Structure "record case / end" (there's only one "end" statement and "case" is
48 ignored as fold point)
49 2. Forward class declarations ("type TMyClass = class;") and object method
50 declarations ("TNotifyEvent = procedure(Sender: TObject) of object;") are
51 ignored as fold points
52 3. Simplified complete class declarations ("type TMyClass = class(TObject);")
53 are ignored as fold points
54 4. Every other situation when class keyword doesn't actually start class
55 declaration ("class procedure", "class function", "class of", "class var",
56 "class property" and "class operator")
57 5. Forward (disp)interface declarations ("type IMyInterface = interface;") are
58 ignored as fold points
60 - Folding of code blocks inside preprocessor blocks is disabled (any comments
61 inside them will be folded fine) because there is no guarantee that complete
62 code block will be contained inside folded preprocessor block in which case
63 folded code block could end prematurely at the end of preprocessor block if
64 there is no closing statement inside. This was done in order to properly process
65 document that may contain something like this:
67 type
68 {$IFDEF UNICODE}
69 TMyClass = class(UnicodeAncestor)
70 {$ELSE}
71 TMyClass = class(AnsiAncestor)
72 {$ENDIF}
73 private
74 ...
75 public
76 ...
77 published
78 ...
79 end;
81 If class declarations were folded, then the second class declaration would end
82 at "$ENDIF" statement, first class statement would end at "end;" statement and
83 preprocessor "$IFDEF" block would go all the way to the end of document.
84 However, having in mind all this, if you want to enable folding of code blocks
85 inside preprocessor blocks, you can disable folding of preprocessor blocks by
86 changing "fold.preprocessor" property, in which case everything inside them
87 would be folded.
89 ~ KEYWORDS:
91 The list of keywords that can be used in pascal.properties file (up to Delphi
92 XE4):
94 - Keywords: absolute abstract and array as asm assembler automated begin case
95 cdecl class const constructor delayed deprecated destructor dispid dispinterface
96 div do downto dynamic else end except experimental export exports external far
97 file final finalization finally for forward function goto helper if
98 implementation in inherited initialization inline interface is label library
99 message mod near nil not object of on operator or out overload override packed
100 pascal platform private procedure program property protected public published
101 raise record reference register reintroduce repeat resourcestring safecall
102 sealed set shl shr static stdcall strict string then threadvar to try type unit
103 unsafe until uses var varargs virtual while winapi with xor
105 - Keywords related to the "smart highlithing" feature: add default implements
106 index name nodefault read readonly remove stored write writeonly
108 - Keywords related to Delphi packages (in addition to all above): package
109 contains requires
