for example, I want to comment out all printLog() functions in a file:
//printLog();
printLog();
//printLog();
but some printLog() are already comment out, and replacing printLog() with //printLog() directly would result in:
////printLog();
//printLog();
////printLog();
is it possible to replace "printLog();" into "//printLog();" but not "printLog();" originally in "//printLog();"?
