&quot; Some Clean-keywords
syn keyword cleanConditional if case
syn keyword cleanLabel let! with where in of
syn keyword cleanSpecial Start
syn keyword cleanKeyword infixl infixr infix
syn keyword cleanBasicType Int Real Char Bool String
syn keyword cleanSpecialType World ProcId Void Files File
syn keyword cleanModuleSystem module implementation definition system
syn keyword cleanTypeClass class instance export

&quot; Import highlighting
syn region cleanIncludeRegion start=&quot;^\s*\(from\|import\|\s\+\(as\|qualified\)\)&quot; end=&quot;\n&quot; contains=cleanIncludeKeyword keepend
syn keyword cleanIncludeKeyword contained from import as qualified

&quot; To do some Denotation Highlighting
syn keyword cleanBoolDenot True False
syn region cleanStringDenot start=+&quot;+ skip=+\(\(\\\\\)\+\|\\&quot;\)+ end=+&quot;+ display
syn match cleanCharDenot &quot;'\(\\\\\|\\'\|[^'\\]\)\+'&quot; display
syn match cleanIntegerDenot &quot;[\~+-]\?\&lt;\(\d\+\|0[0-7]\+\|0x[0-9A-Fa-f]\+\)\&gt;&quot; display
syn match cleanRealDenot &quot;[\~+-]\?\d\+\.\d\+\(E[\~+-]\?\d\+\)\?&quot; display

&quot; To highlight the use of lists, tuples and arrays
syn region cleanList start=&quot;\[&quot; end=&quot;\]&quot; contains=ALL
syn region cleanRecord start=&quot;{&quot; end=&quot;}&quot; contains=ALL
syn region cleanArray start=&quot;{:&quot; end=&quot;:}&quot; contains=ALL
syn match cleanTuple &quot;([^=]*,[^=]*)&quot; contains=ALL

&quot; To do some Comment Highlighting
syn region cleanComment start=&quot;/\*&quot;  end=&quot;\*/&quot; contains=cleanComment,cleanTodo fold
syn region cleanComment start=&quot;//.*&quot; end=&quot;$&quot; display contains=cleanTodo
syn keyword cleanTodo TODO FIXME XXX contained

&quot; Now for some useful type definition recognition
syn match cleanFuncTypeDef &quot;\([a-zA-Z].*\|(\=[-~@#$%^?!+*&lt;&gt;\/|&amp;=:]\+)\=\)\s*\(infix[lr]\=\)\=\s*\d\=\s*::.*-&gt;.*&quot; contains=cleanSpecial,cleanBasicType,cleanSpecialType,cleanKeyword


&quot; Define the default highlighting.
&quot; Only when an item doesn't have highlighting yet
