No need to apologise for deeply-held convictions :-) The important issue is that the "official style" as described here: http://www.rebol.com/docs/core23/rebolcore-5.html isn't used by all of us. So a pretty-printer that can convert between the major styles will be of use to us all. Carl is on record as saying it isn't possible to do one. But I think he's looking from a purist computer science perspective. From an engineering perspective, we could easily do something that handles 95% of all practical cases. *** There are two big problems: First words *may* be redefined: if a = 1 [ print true ] [print false] Is correctly indented according to the official style. Unless it were preceded by if: :either when it should be if a = 1 [ print true ][ print false ] And what if it is in a loop -- how best to stylise this code? loop 2 [ if a = 1 [print true][print false] if: :either ] The best engineering solution to problem 1 is to ignore it. Same as Carl's code coloring scripts do. Treat the source as seen when statically loaded. *** Problem 2 is that the guidelines assume start and end block characters, but they are not always needed: if 1 = 2 load "do [print 'different]" Or should 'load be treated as if were the open square bracket? if 1 = 2 load "do [print 'different]" Again, the best thing to do is ignore that. Anyone with that problem would be welcome to extend the code to handle it. *** I'd welcome a strong (as in powerful) prettyprinter that can convert between different styles. The those of us who publish scripts can happily write them our way, and publish them to the official style.
