Re: vim can't find carriage returns

Hi JP Lew,

 

Your discovery works great:

:g/^$/d

Depending what you consider a "blank line", you may want:

:g/^\s*$/d

 

If you want to delete runs of blank lines over a threshhold, that can be done as well.  One way to do it is a search-and-replace command like:

:%s/\n\{2,\}/\r\r/

 

I'm not sure why I have to search FOR multiple \n and replace WITH the \r.  That may be a vi-thing, a Vim-thing, or a quirk / detail of my platform (Windows 7, using the prebuilt gVim, using :set ff=unix line endings).  Hmmm, I never thought about that discrepancy before.  The help on it...

:help sub-replace-special

...doesn't really explain the discrepancy.  My speculation is that the discrepancy probably has to do with Vim ingesting a text file as strings, and those lines are stripped of the line endings and are '\0' terminated.  Which would make the discrepancy an implementation detail.

 

There are a lot of powerful editors available.  Vim is more than a powerful editor.  Vim is zen editing.  Vim lets me become one with my keyboard and edit my document; all the while the editor is not a distracting interface but rather is unobtrusive.

 

Happy Vim-ming!

Eljay
