18 " d_comment_strings - Set to highlight strings and numbers in comments.

|
19 "
|
|
2043
|
20 " d_hl_operator_overload - Set to highlight D's specially named functions
|
|
|
21 " that when overloaded implement unary and binary operators (e.g. opCmp).

|
22 "
|
|
|
23 " Todo:
|
|
2043
|
24 " - Determine a better method of sync'ing than simply setting minlines
|
|
|
25 " to a large number.
|
|
7
|
26 "
|
|
2043
|
27 " - Several keywords (e.g., in, out, inout) are both storage class and
|
|
|
28 " statements, depending on their context. Perhaps use pattern matching to
|
|
|
29 " figure out which and highlight appropriately. For now I have made such
|
|
|
30 " keywords storage classes so their highlighting is consistent with other
|
|
|
31 " keywords that are commonly used with them, but are true storage classes,
|
|
|
32 " such as lazy. Similarly, I made some statement keywords (e.g. body) storage
|
|
|
33 " classes.
|
|
7
|
34 "
|
|
|
35 " - Mark contents of the asm statement body as special
|
|
|
36 "
|
|
2043
|
37 " - Maybe highlight the 'exit', 'failure', and 'success' parts of the
|
|
|
38 " scope() statement.
|
|
|
39 "
|
|
|
40 " - Highlighting DDoc comments.
