A very simple approach would be technically incorrect in some cases but may work for your needs: :%s#if\s*(\_[^)]*)\zs\s*\(.*;\)#\r\1 This will separate any single-condition if statements from code on the same line. You will then need to re-indent. You could do this with gg=G for the whole file, or be smarter and only reindent the line after any "if" statement with: :g#\<if\>#+norm! == If your actual code is more complex than that (including nested parentheses), then there is no good way to match arbitrary levels of nested parentheses using regular expression find+replace. For this one method would be to record a macro to search for an if statement and fix it, then go to the beginning of the file and apply it as many times as needed. You can do "as many times as needed" in a way that stops when done by setting 'nowrapscan' and running the macro an excessive number of times. For example: qa/\<if\>.*;<Enter>f(%lr<Enter>==q :set nowrapscan gg 9999999@a :set wrapscan " optional Unlike using a substitute command, this uses the % command to move to the matching parenthesis, instead of attempting to write a regex to count parentheses. -- -- You received this message from the "vim_use" maillist.
