I've been thinking about your proposed patch and I would have one problem with it: it doesn't seem intuitive and although I do work with software projects with quite large amounts of source code, I don't think I would use it much (because I wouldn't be able to remember all the quirks of the command). However, I think that there is a very simple solution to your problem which does not require changing the behaviour of Vim itself: create a command in VimL which will do everything you need. For this command I would use the following: - input() – for getting the name of the tag to jump to, - taglist() – to get a list of tags matching what the user chose to view, - input() – to get the name of the class, - input() – to get the file name pattern, - match() – to filter the tag list returned by taglist() with the criteria based on the values input by the user, - setqflist(), setloclist() – to create a list displayed in the quickfix window (:copen, :lopen), - inputlist() – perhaps instead of using setqflist() to make the experience akin to using :tselect. I believe that using such a command should be much more pleasant than poring through hundreds of lines of output generated by grep. And it has the potential of being more user-friendly – whenever you use input(), you can help the user by providing a hint in the prompt. What do you think? I'll be happy to hear from you. -- Cheers, Lech -- -- You received this message from the "vim_dev" maillist. Do not top-post! Type your reply below the text you are replying to.
