+ Ruby: Folding ~
 
-Highlighting of special identifiers can be disabled by removing the
-rubyIdentifier highlighting: >
+Folding can be enabled by defining "ruby_fold": >
 
-	:hi link rubyIdentifier NONE
+	:let ruby_fold = 1
 <
-This will prevent highlighting of special identifiers like "ConstantName",
-"$global_var", "@@class_var", "@instance_var", "| block_param |", and
-":symbol".
+This will set the value of 'foldmethod' to "syntax" locally to the current
+buffer or window, which will enable syntax-based folding when editing Ruby
+filetypes.
+
+						*ruby_foldable_groups*
+Default folding is rather detailed, i.e., small syntax units like "if", "do",
+"%w[]" may create corresponding fold levels.
 
-Significant methods of Kernel, Module and Object are highlighted by default.
-This can be disabled by defining "ruby_no_special_methods": >
+You can set "ruby_foldable_groups" to restrict which groups are foldable: >
 
-	:let ruby_no_special_methods = 1
+        :let ruby_foldable_groups = 'if case %'
 <
-This will prevent highlighting of important methods such as "require", "attr",
-"private", "raise" and "proc".
+The value is a space-separated list of keywords:
+
+    keyword       meaning ~
+    --------  ------------------------------------- ~
+    ALL        Most block syntax (default)
+    NONE       Nothing
+    if         "if" or "unless" block
+    def        "def" block
+    class      "class" block
+    module     "module" block
+    do         "do" block
+    begin      "begin" block
+    case       "case" block
+    for        "for", "while", "until" loops
+    {          Curly bracket block or hash literal
+    [          Array literal
+    %          Literal with "%" notation, e.g.: %w(STRING), %!STRING!
+    /          Regexp
+    string     String and shell command output (surrounded by ', ", `)
+    :          Symbol
