Tabs v spaces As Peter said, the most important part is consistency. Mixing tabs and spaces together makes no one happy. I will throw out a couple arguments for tabs here: Indentation of code, markup language, et. cetera is meant to show the structure of whatever. Tabs are a logical, structural element. Spaces are physical. Different users may want different sizes of indentation. If i want 4 character indentation and my coworker wants 2, tabs can be set to show our preferred width. Seems for the most part that spaces are winning out though.

Hello, @alan-kilborn, You said : For clarity for future readers of this thread, which method is this one? I was referring to these steps : First, run a Edit > Blank Operations > TAB to Space option Then run the regex replacement below, where C represents the maximum number of chars after you want a line-break : SEARCH [\x20\r\n]*\z|(?-s)^(?=.{C+1,}).{1,C}\K(?:\x20*\R|\x20+) REPLACE \r\n for Windows files    or    \n for Unix files Finally, run a Edit > Blank operations > Trim Trailing Space option You then said : And, because I’m currently away from my Notepad++ and can’t try it myself, why are these "must be OFF"s? I must apologize because I was mistaken ! I did some other tests and it happens that the status of the View > Word wrap does not matter But I confirm that showing the line-endings chars breaks the correct spliting of text when using the Edit > Line Operations > Split Lines option STR : In Settings > Preferences... > Margins/Border/Edge > Vertical Edge Settings insert the value 78 , ONLY For clarity, just uncheck the View > Word wrap option and the View > Show Symbol option Paste the beginning of the License.txt file, below, in a new tab : COPYING -- Describes the terms under which Notepad++ is distributed.
