" Vim syntax file " Language: CSP (Communication Sequential Processes, using FDR input syntax) " Maintainer: Jan Bredereke <brederek@tzi.de> " Version: 0.6.0 " Last change: Mon Mar 25, 2002 " URL: http://www.tzi.de/~brederek/vim/ " Copying: You may distribute and use this file freely, in the same " way as the vim editor itself. " " To Do: - Probably I missed some keywords or operators, please " fix them and notify me, the maintainer. " - Currently, we do lexical highlighting only. It would be " nice to have more actual syntax checks, including " highlighting of wrong syntax. " - The additional syntax for the RT-Tester (pseudo-comments) " should be optional. " For version 5.x: Clear all syntax items " For version 6.x: Quit when a syntax file was already loaded if version < 600 syntax clear elseif exists("b:current_syntax") finish endif " case is significant to FDR: syn case match " Block comments in CSP are between {- and -} syn region cspComment start="{-" end="-}" contains=cspTodo " Single-line comments start with -- syn region cspComment start="--" end="$" contains=cspTodo,cspOldRttComment,cspSdlRttComment keepend " Numbers: syn match cspNumber "\<\d\+\>" " Conditionals: syn keyword cspConditional if then else " Operators on processes: " -> ? : !
