" For version 5.x: Clear all syntax items

" Don't ignore case (Modula-2 is case significant). This is the default in vim

syn region modula2Keyword start="END" end=";" contains=ALLBUT,modula2Ident oneline

" Some very important keywords which should be emphasized more than others:
|
|
syn keyword modula2AttKeyword CONST EXIT HALT RETURN TYPE VAR
|
|
" All other keywords in alphabetical order:
|
|
syn keyword modula2Keyword AND ARRAY BY CASE DEFINITION DIV DO ELSE

syn keyword modula2Keyword ELSIF EXPORT FOR FROM IF IMPLEMENTATION IMPORT
|
|
syn keyword modula2Keyword IN LOOP MOD NOT OF OR POINTER QUALIFIED RECORD

" The following may be discussed, since NEW and DISPOSE are some kind of
|
|
" special builtin macro functions:
|
|
syn keyword modula2StdFunc NEW DISPOSE
|
|
" The following types are added later on and may be missing from older
|
|
" Modula-2 Compilers (they are at least missing from the original report
|
|
" by N.Wirth from March 1980 ;-) Highlighting should apply nevertheless:
|
|
syn keyword modula2Type BYTE LONGCARD LONGINT LONGREAL PROC SHORTCARD SHORTINT
|
|
" same note applies to min and max, which were also added later to m2:
|
|
syn keyword modula2StdFunc MAX MIN
|
|
" The underscore was originally disallowed in m2 ids, it was also added later:
|
|
syn match modula2Ident " [A-Z,a-z][A-Z,a-z,0-9,_]*" contained
|
|
|
|
" Comments may be nested in Modula-2:

syn keyword modula2Todo contained TODO FIXME XXX
