|
9 " d_comment_strings - set to highlight strings and numbers in comments
|
|
|
10 "
|
|
|
11 " d_hl_operator_overload - set to highlight D's specially named functions
|
|
|
12 " that when overloaded implement unary and binary operators (e.g. cmp).

|
14 " Todo:
|
|
|
15 " - Allow user to set sync minlines
|
|
|
16 "
|
|
|
17 " - Several keywords (namely, in and out) are both storage class and
|
|
|
18 " statements, depending on their context. Must use some matching to figure
|
|
|
19 " out which and highlight appropriately. For now I have made such keywords
|
|
|
20 " statements.
|
|
|
21 "
|
|
|
22 " - Mark contents of the asm statement body as special
