I like the idea, as dealing with all the different options is indeed painful for script writers. On the other hand, it's not that by setting this flag, you can now completely forget about the differences; it depends on what your function is actually doing, there may be other options affecting your functions, and sometime you do want to observe e.g. the 'ignorecase' setting. Add to that that for backwards compatibility, scripts have to accommodate the various settings for a long time to come, and it's less helpful - at least in the near time frame. Also note that resetting 'selection' may help with making and modifying a selection entirely within your function, but based on my experience, when you want to work on an existing selection made by the user or leave a selection behind (as in a text object), you have to consider the actual 'selection' value, as the end position '> is not automatically adjusted when the option changes. -- regards, ingo -- You received this message from the "vim_dev" maillist.
