Editing: dtrace.vim
" 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 " http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/lib/libdtrace/common/dt_grammar.y " quit when a syntax file was already loaded if exists("b:current_syntax") finish endif " Read the C syntax to start with runtime! syntax/c.vim unlet b:current_syntax syn clear cCommentL " dtrace doesn't support // style comments " First line may start with #!, also make sure a '-s' flag is somewhere in " that line. syn match dtraceComment "\%^#!.*-s.*" " 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.

" 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.
