1" Vim syntax file 2" Language: CSP (Communication Sequential Processes, using FDR input syntax) 3" Maintainer: Jan Bredereke <[email protected]> 4" Version: 0.6.0 5" Last change: Mon Mar 25, 2002 6" URL: http://www.tzi.de/~brederek/vim/ 7" Copying: You may distribute and use this file freely, in the same 8" way as the vim editor itself. 9" 10" To Do: - Probably I missed some keywords or operators, please 11" fix them and notify me, the maintainer. 12" - Currently, we do lexical highlighting only. It would be 13" nice to have more actual syntax checks, including 14" highlighting of wrong syntax. 15" - The additional syntax for the RT-Tester (pseudo-comments) 16" should be optional. 17 18" quit when a syntax file was already loaded 19if exists("b:current_syntax") 20 finish 21endif 22 23" case is significant to FDR: 24syn case match 25 26" Block comments in CSP are between {- and -} 27syn region cspComment start="{-" end="-}" contains=cspTodo 28" Single-line comments start with -- 29syn region cspComment start="--" end="$" contains=cspTodo,cspOldRttComment,cspSdlRttComment keepend 30 31" Numbers: 32syn match cspNumber "\<\d\+\>" 33 34" Conditionals: 35syn keyword cspConditional if then else 36 37" Operators on processes: 38" -> ? : !
