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 7" Maintainer: Nicolas Weber <[email protected]> 8 9" dtrace lexer and parser are at 10" http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/lib/libdtrace/common/dt_lex.l 11" http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/lib/libdtrace/common/dt_grammar.y 12 13" quit when a syntax file was already loaded 14if exists("b:current_syntax") 15 finish 16endif 17 18" Read the C syntax to start with 19runtime! syntax/c.vim 20unlet b:current_syntax 21 22syn clear cCommentL " dtrace doesn't support // style comments 23 24" First line may start with #!, also make sure a '-s' flag is somewhere in 25" that line. 26syn match dtraceComment "\%^#!.*-s.*" 27 28" Probe descriptors need explicit matches, so that keywords in probe 29" descriptors don't show up as errors. Note that this regex detects probes 30" as "something with three ':' in it". This works in practice, but it's not 31" really correct. Also add special case code for BEGIN, END and ERROR, since 32" they are common. 33" Be careful not to detect '/*some:::node*/\n/**/' as probe, as it's 34" commented out. 35" XXX: This allows a probe description to end with ',', even if it's not 36" followed by another probe. 37" XXX: This doesn't work if followed by a comment. 38let s:oneProbe = '\%(BEGIN\|END\|ERROR\|\S\{-}:\S\{-}:\S\{-}:\S\{-}\)\_s*' 39exec 'syn match dtraceProbe "'.s:oneProbe.'\%(,\_s*'.s:oneProbe.'\)*\ze\_s\%({\|\/[^*]\|\%$\)"' 40 41" Note: We have to be careful to not make this match /* */ comments. 42" Also be careful not to eat `c = a / b; b = a / 2;`. We use the same 43" technique as the dtrace lexer: a predicate has to be followed by {, ;, or 44" EOF. Also note that dtrace doesn't allow an empty predicate // (we do). 45" This regex doesn't allow a divison operator in the predicate. 46" Make sure that this matches the empty predicate as well. 47" XXX: This doesn't work if followed by a comment. 48syn match dtracePredicate "/\*\@!\_[^/]*/\ze\_s*\%({\|;\|\%$\)" 49 "contains=ALLBUT,dtraceOption " this lets the region contain too much stuff 50 51" Pragmas. 52" dtrace seems not to support whitespace before or after the '='. dtrace 53" supports only one option per #pragma, and no continuations of #pragma over 54" several lines with '\'. 55" Note that dtrace treats units (Hz etc) as case-insenstive, we allow only 56" sane unit capitalization in this script (ie 'ns', 'us', 'ms', 's' have to be 57" small, Hertz can be 'Hz' or 'hz') 58" XXX: "cpu" is always highlighted as builtin var, not as option 59 60" auto or manual: bufresize 61syn match dtraceOption contained "bufresize=\%(auto\|manual\)\s*$" 62 63" scalar: cpu jstackframes jstackstrsize nspec stackframes stackindent ustackframes 64syn match dtraceOption contained "\%(cpu\|jstackframes\|jstackstrsize\|nspec\|stackframes\|stackindent\|ustackframes\)=\d\+\s*$" 65 66" size: aggsize bufsize dynvarsize specsize strsize 67" size defaults to something if no unit is given (ie., having no unit is ok) 68syn match dtraceOption contained "\%(aggsize\|bufsize\|dynvarsize\|specsize\|strsize\)=\d\+\%(k\|m\|g\|t\|K\|M\|G\|T\)\=\s*$" 69 70" time: aggrate cleanrate statusrate switchrate 71" time defaults to hz if no unit is given 72syn match dtraceOption contained "\%(aggrate\|cleanrate\|statusrate\|switchrate\)=\d\+\%(hz\|Hz\|ns\|us\|ms\|s\)\=\s*$" 73 74" No type: defaultargs destructive flowindent grabanon quiet rawbytes 75syn match dtraceOption contained "\%(defaultargs\|destructive\|flowindent\|grabanon\|quiet\|rawbytes\)\s*$" 76 77 78" Turn reserved but unspecified keywords into errors 79syn keyword dtraceReservedKeyword auto break case continue counter default do 80syn keyword dtraceReservedKeyword else for goto if import probe provider 81syn keyword dtraceReservedKeyword register restrict return static switch while 82 83" Add dtrace-specific stuff 84syn keyword dtraceOperator sizeof offsetof stringof xlate 85syn keyword dtraceStatement self inline xlate this translator 86 87" Builtin variables 88syn keyword dtraceIdentifier arg0 arg1 arg2 arg3 arg4 arg5 arg6 arg7 arg8 arg9 89syn keyword dtraceIdentifier args caller chip cpu curcpu curlwpsinfo curpsinfo 90syn keyword dtraceIdentifier curthread cwd epid errno execname gid id ipl lgrp 91syn keyword dtraceIdentifier pid ppid probefunc probemod probename probeprov 92syn keyword dtraceIdentifier pset root stackdepth tid timestamp uid uregs 93syn keyword dtraceIdentifier vtimestamp walltimestamp 94syn keyword dtraceIdentifier ustackdepth 95 96" Macro Variables 97syn match dtraceConstant "$[0-9]\+" 98syn match dtraceConstant "$\(egid\|euid\|gid\|pgid\|ppid\)" 99syn match dtraceConstant "$\(projid\|sid\|target\|taskid\|uid\)" 100 101" Data Recording Actions 102syn keyword dtraceFunction trace tracemem printf printa stack ustack jstack 103 104" Process Destructive Actions 105syn keyword dtraceFunction stop raise copyout copyoutstr system 106 107" Kernel Destructive Actions 108syn keyword dtraceFunction breakpoint panic chill 109 110" Special Actions 111syn keyword dtraceFunction speculate commit discard exit 112 113" Subroutines 114syn keyword dtraceFunction alloca basename bcopy cleanpath copyin copyinstr 115syn keyword dtraceFunction copyinto dirname msgdsize msgsize mutex_owned 116syn keyword dtraceFunction mutex_owner mutex_type_adaptive progenyof 117syn keyword dtraceFunction rand rw_iswriter rw_write_held speculation 118syn keyword dtraceFunction strjoin strlen 119 120" Aggregating Functions 121syn keyword dtraceAggregatingFunction count sum avg min max lquantize quantize 122 123syn keyword dtraceType int8_t int16_t int32_t int64_t intptr_t 124syn keyword dtraceType uint8_t uint16_t uint32_t uint64_t uintptr_t 125syn keyword dtraceType string 126syn keyword dtraceType pid_t id_t 127 128 129" Define the default highlighting. 130" We use `hi def link` directly, this requires 5.8. 131hi def link dtraceReservedKeyword Error 132hi def link dtracePredicate String 133hi def link dtraceProbe dtraceStatement 134hi def link dtraceStatement Statement 135hi def link dtraceConstant Constant 136hi def link dtraceIdentifier Identifier 137hi def link dtraceAggregatingFunction dtraceFunction 138hi def link dtraceFunction Function 139hi def link dtraceType Type 140hi def link dtraceOperator Operator 141hi def link dtraceComment Comment 142hi def link dtraceNumber Number 143hi def link dtraceOption Identifier 144 145let b:current_syntax = "dtrace" 146
