    OK. I asked before so this is a repost... (so sue me...) Is there a plain (text) editor which can remove empty lines ? It would be nice to add as "plug in" into my "development tool"... Thanks

      Specifically, for most files replace '\r\n' with nothing, and select 'Extended' in the options

      No, that'll collapse everything to a single line! To remove blank lines, in Regular Expression mode replace \r\n(\r\n)+ with \r\n That assumes that the blank lines don't have any whitespace. If they might, then replace \r\n(\s*\r\n)+ with \r\n

        Nice. I copied about 4000 lines of code and copied it back to my .cpp file. I will try to see how my current messy " under construction " file looks now ,,, I would probably do "CodeBeautifier" when my code gets too messy... about hourly... just kidding Thanks

          If you're looking to reformat your code, you might want to take a look at [ClangFormat — Clang 18.0.0git documentation](https://clang.llvm.org/docs/ClangFormat.html) Depending on which IDE you're using, you may find that others have already created plug-ins for it. A quick google around suggests that Visual Studio and QtCreator both have instructions on how to integerate.

            Thanks! I was being brain dead. I have removed blank lines the way you showed before but dyslexia kicked in.

              VIM or NeoVim can do this. [https://stackoverflow.com/questions/706076/vim-delete-blank-lines#706083\](https://stackoverflow.com/questions/706076/vim-delete-blank-lines#706083) When I first started with VI I hated it. The more I learn though, the better it is. It's my editor of choice now, but I confess I don't use it enough to keep all the goodness in my head, and I often need a few moments to get into the VIM headspace when I start.

                Or 'Edit' -> 'Line Operations' -> 'Remove Empty Lines'

                      I have a little note for that for VS Code:

                      vscode: ^$\n (to remove empty lines)

                      And I don't believe it was with any particular extension.

                        That's what I was thinking; you don't need a separate tool to remove blank lines; a regex search and replace ought to do it. My real question (to the OP) is, does he want the editor to keep the blank lines but just not show them, or really remove them altogether?

                            Don't know (and IDC) about plugin into any development system, but for years, I am using PsPad as my go-to plain text editor on Windows, and it has a function to remove blanks lines (and many other options)...
