Feature #8321

Updated by nobu (Nobuyoshi Nakada) over 8 years ago

 Ripper gives the (({[line, column]})) [line, column] coordinates for identifiers, strings, and numbers. 

 I would like it if it appended those coordinates to most of the block keywords, 
 including (({:program})), (({:if})), (({:while})), (({:unless})), (({:end})), (({:def})), (({:class})), (({:module})), :program, :if, :while, :unless, :end, :def, :class, :module, etc.    As with the 
 identifiers, it should go at the end.    So an (({if}))-block if-block would be represented as 
 [0] :if 
 [2] BLOCK 
 [3] [:elsif, ...] || [:else, ...] || nil 
 [4] [lineNo, colNo] # location of the leading :if/:elsif/:else/:unless 

 I currently get the first coordinate of ((%CONDITION%)), CONDITION, and then look up the preceding 
 (({:if}))/(({:elsif}))/(({:else})) :if/:elsif/:else using (({Ripper.lex(src).find_all{|posn Ripper.lex(src).find_all{|posn kwd name| kwd == :on_kw && %w/if else elsif/.include?(name) }})) } 

 So the info is in Ripper.    It would be more convenient if I could get that info in the src tree. 

 Note that my suggestion won't break (most) existing code, as the new data goes at the end 
 of the list. 

 The same would be useful for other keywords, including (({:module})) (({:class})) (({:def})) (({:try})) (({:catch})) (({:begin})) (({:rescue})). 
 :module :class :def :try :catch :begin :rescue
