Folks,
I am trying to embed perl syntax, but it seems that somehow my new cluster
contains definitions from the perl.vim that were already contained. I think
that doesn't make sense, or at least, when I figured out to remove them from
the cluster, things started working:
syntax include @perlOnly syntax/perl.vim
let b:current_syntax = "calibre"
syntax cluster perlOnly
remove=perlAnglesDQ,perlAnglesSQ,perlArrow,perlBracesDQ,perlBracesSQ,perlBracketsDQ,perlBracketsSQ,perlElseIfError,perlFiledescStatement,perlFiledescStatementComma,perlFiledescStatementNocomma,perlFormatField,perlFormatName,perlFunctionName,perlFunctionPRef,perlGenericBlock,perlMethod,perlNotEmptyLine,perlPackageRef,perlParensDQ,perlParensSQ,perlSpecialMatch,perlSpecialString,perlSpecialStringU,perlSpecialStringU2,perlStatementPackage,perlSubAttributes,perlSubAttributesCont,perlSubError,perlSubName,perlSubPrototype,perlSubPrototypeError,perlSubstitutionGQQ,perlSubstitutionSQ,perlTodo,perlTranslationGQ,perlVStringV,perlVarMember,perlVarSimpleMember,perlVarSimpleMemberName
syntax region calibrePerl matchgroup=Structure start=/\[\[/ end=/\]\]/
contains=@perlOnly
The list of removed sections is created simply from
grep "\<contained\>" perl.vim | while read line; do echo perl${line#*perl}};
done | cut -f 1 -d\ | sort -u | tr "\\n" ","
The documentation states:
All syntax items declared in the included file will have the
"contained" flag added. In addition, if a group list is specified,
all top-level syntax items in the included file will be added to
that list. >
So, if I'm reading that correctly (and I'm very new at this, I could be
entirely in the wrong tree), it does seem to imply that syntax elements that
already have "contained" in the syntax included file should NOT be placed in to
the new list name. This makes sense, I think, because they expect to be
included ONLY in regions/clusters/etc that are defined internally in the
perl.vim file. I suspect this revolves around this in the perl.vim:
syn cluster perlTop contains=TOP
... but I don't know how to really explore what's going on.
Any advice here would be appreciated!
