First, it looks like this will fold more than you want, but just in case it
is acceptable to you, have you tried the Ruby syntax folding?
See :help ruby.vim for the options on Ruby syntax. Near the end are the
folding options ruby_fold and ruby_no_comment_fold.
If all you want is the specific blocks you mention, and if you're not too
worried about being precisely correct, you could make a foldexpr which
depends on not only the beginning of the match but also the end being in the
first column. Something like:
fun! MyFoldBlocks()
if getline(v:lnum)=~'\v^(if|(\S&.*\{)|SomeOtherBlockBeginning)'
return ">1"
elseif getline(v:lnum)=~'\v^(end|\}|SomeOtherBlockEnding)'
return "<1"
else
return "="
endif
endfun
setl foldexpr=MyFoldBlocks() fdm=expr
