You can't. When reading the undo history, vim checks, that the checksum between the undo-file and the current open file match and that their line numbers are the same, if not, Vim will complain with an error (if you have set verbose to a value larger than zero). Even if you'd patch vim, to not check the hash size and number of lines it wouldn't work, because the undo file does not contain the whole file content, but only the content that changed between each file change. So if you changed the source of vim, you could only recover the lines that you actually changed, but all the lines that were not changed (and therefore not recorded in the undofile) would still be lost. That would only work, if you had previously reloaded your whole buffer using :e! and 'undoreload' was set to a negative number (or you file contained less than that number of lines). If you know, the whole file content was previously saved in your undofile and you'd like to try out reloading your changes, let me know. I made a patch, that enables you to force reloading the undo history, which you could try out if you want. But that is not very useful by itself. regards, Christian -- You received this message from the "vim_use" maillist. Do not top-post! Type your reply below the text you are replying to.
