Is there any way I could use folding to do this: 1. Fold all lines in a file that contain only comments.
2. Optionally delete all the lines that have previously been folded. I have a feeling I am looking for something less sophisticated than the fold feature where I could remove all lines that contain a given pattern - say, # or /* in col. 1, from a buffer and I am not sure folding is the feature I should be looking at. An example of possible use: I would find this useful when trying to prune some configuration file that has some ten lines of comments for every entry so that I can have more or less the entire configuration file fit on one screen instead of fifteen or twenty. A more general definition of this need/problem might be to 'remove all lines that match a certain pattern from the buffer - and optionally from the file itself'. Thanks. cga
