" 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. " XXX: This doesn't work if followed by a comment. let s:oneProbe = '\%(BEGIN\|END\|ERROR\|\S\{-}:\S\{-}:\S\{-}:\S\{-}\)\_s*' exec 'syn match dtraceProbe "'.s:oneProbe.'\%(,\_s*'.s:oneProbe.'\)*\ze\_s\%({\|\/[^*]\|\%$\)"' " 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.

" 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') " XXX: "cpu" is always highlighted as builtin var, not as option " auto or manual: bufresize syn match dtraceOption contained "bufresize=\%(auto\|manual\)\s*$" " scalar: cpu jstackframes jstackstrsize nspec stackframes stackindent ustackframes syn match dtraceOption contained "\%(cpu\|jstackframes\|jstackstrsize\|nspec\|stackframes\|stackindent\|ustackframes\)=\d\+\s*$" " size: aggsize bufsize dynvarsize specsize strsize " size defaults to something if no unit is given (ie., having no unit is ok) syn match dtraceOption contained "\%(aggsize\|bufsize\|dynvarsize\|specsize\|strsize\)=\d\+\%(k\|m\|g\|t\|K\|M\|G\|T\)\=\s*$" " time: aggrate cleanrate statusrate switchrate " time defaults to hz if no unit is given syn match dtraceOption contained "\%(aggrate\|cleanrate\|statusrate\|switchrate\)=\d\+\%(hz\|Hz\|ns\|us\|ms\|s\)\=\s*$" " No type: defaultargs destructive flowindent grabanon quiet rawbytes syn match dtraceOption contained "\%(defaultargs\|destructive\|flowindent\|grabanon\|quiet\|rawbytes\)\s*$" " Turn reserved but unspecified keywords into errors syn keyword dtraceReservedKeyword auto break case continue counter default do syn keyword dtraceReservedKeyword else for goto if import probe provider syn keyword dtraceReservedKeyword register restrict return static switch while " Add dtrace-specific stuff syn keyword dtraceOperator sizeof offsetof stringof xlate syn keyword dtraceStatement self inline xlate this translator " Builtin variables syn keyword dtraceIdentifier arg0 arg1 arg2 arg3 arg4 arg5 arg6 arg7 arg8 arg9 syn keyword dtraceIdentifier args caller chip cpu curcpu curlwpsinfo curpsinfo syn keyword dtraceIdentifier curthread cwd epid errno execname gid id ipl lgrp syn keyword dtraceIdentifier pid ppid probefunc probemod probename probeprov syn keyword dtraceIdentifier pset root stackdepth tid timestamp uid uregs syn keyword dtraceIdentifier vtimestamp walltimestamp syn keyword dtraceIdentifier ustackdepth " Macro Variables syn match dtraceConstant "$[0-9]\+" syn match dtraceConstant "$\(egid\|euid\|gid\|pgid\|ppid\)" syn match dtraceConstant "$\(projid\|sid\|target\|taskid\|uid\)" " Data Recording Actions syn keyword dtraceFunction trace tracemem printf printa stack ustack jstack " Process Destructive Actions syn keyword dtraceFunction stop raise copyout copyoutstr system " Kernel Destructive Actions syn keyword dtraceFunction breakpoint panic chill " Special Actions syn keyword dtraceFunction speculate commit discard exit " Subroutines syn keyword dtraceFunction alloca basename bcopy cleanpath copyin copyinstr syn keyword dtraceFunction copyinto dirname msgdsize msgsize mutex_owned syn keyword dtraceFunction mutex_owner mutex_type_adaptive progenyof syn keyword dtraceFunction rand rw_iswriter rw_write_held speculation syn keyword dtraceFunction strjoin strlen " Aggregating Functions syn keyword dtraceAggregatingFunction count sum avg min max lquantize quantize syn keyword dtraceType int8_t int16_t int32_t int64_t intptr_t syn keyword dtraceType uint8_t uint16_t uint32_t uint64_t uintptr_t syn keyword dtraceType string syn keyword dtraceType pid_t id_t " Define the default highlighting.
