+" DTrace D script syntax file. To avoid confusion with the D programming
+" language, I call this script dtrace.vim instead of d.vim.
+" Language: D script as described in "Solaris Dynamic Tracing Guide",
+"           http://docs.sun.com/app/docs/doc/817-6223
+" Version: 1.5
+" Last Change: 2008/04/05
+" Maintainer: Nicolas Weber <nicolasweber@gmx.de>
+
+" dtrace lexer and parser are at
+" http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/lib/libdtrace/common/dt_lex.l

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

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

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