1 " DTrace D script syntax file. To avoid confusion with the D programming
2 " language, I call this script dtrace.vim instead of d.vim.
3 " Language: D script as described in "Solaris Dynamic Tracing Guide",
4 " http://docs.sun.com/app/docs/doc/817-6223
5 " Version: 1.5
6 " Last Change: 2008/04/05

33 " Probe descriptors need explicit matches, so that keywords in probe
34 " descriptors don't show up as errors. Note that this regex detects probes
35 " as "something with three ':' in it". This works in practice, but it's not
36 " really correct. Also add special case code for BEGIN, END and ERROR, since
37 " they are common.
38 " Be careful not to detect '/*some:::node*/\n/**/' as probe, as it's
39 " commented out.
40 " XXX: This allows a probe description to end with ',', even if it's not
41 " followed by another probe.
42 " XXX: This doesn't work if followed by a comment.

46 " Note: We have to be careful to not make this match /* */ comments.
47 " Also be careful not to eat `c = a / b; b = a / 2;`. We use the same
48 " technique as the dtrace lexer: a predicate has to be followed by {, ;, or
49 " EOF. Also note that dtrace doesn't allow an empty predicate // (we do).
50 " This regex doesn't allow a divison operator in the predicate.
51 " Make sure that this matches the empty predicate as well.
52 " XXX: This doesn't work if followed by a comment.

56 " Pragmas.
57 " dtrace seems not to support whitespace before or after the '='. dtrace
58 " supports only one option per #pragma, and no continuations of #pragma over
59 " several lines with '\'.
60 " Note that dtrace treats units (Hz etc) as case-insenstive, we allow only
61 " sane unit capitalization in this script (ie 'ns', 'us', 'ms', 's' have to be
62 " small, Hertz can be 'Hz' or 'hz')
