I've had a bug in one of my plugins that I finally traced to what appears to be a bug in Vim (8.0.1257): a substitution on one line of a closed fold affects all lines in that fold.
Here's an example. Create a file, fold_test, as shown. ---------------------------- fold_test ---------------------------- {{{1 line 2 line 3 line 4 line 5 }}}1 line 7 line 8 line 9 line 10 vim: fdm=marker ------------------------------------------------------------------- Then edit that file as follows. $ vim -N -u NONE -i NONE fold_test Note that lines 1 through 6 are folded. Do the following. :3s/line/dog/ zR Note that "line" has been changed to "dog" in lines 2 through 5. Then do the following. :3s/dog/cat/ Note that "dog" has been changed to "cat" in only line 3, as expected. The result looks like this. {{{1 dog 2 cat 3 dog 4 dog 5 }}}1 line 7 line 8 line 9 line 10 vim: fdm=marker That an explicit substitution on one line affects all lines in the closed fold looks like a bug to me. It is certainly unexpected. Regards, Gary -- -- You received this message from the "vim_dev" maillist. Do not top-post! Type your reply below the text you are replying to.
