VIM Disable Automatic Newline At End Of File

Question

So I work in a PHP shop  and we all use different editors  and we all have to work on windows  I use vim  and everyone in the shop keeps complaining that whenever I edit a file there is a newline at the bottom   I ve searched around and found that this is a documented behavior of vi  amp  vim    but I was wondering if there was some way to disable this feature    It wouldbe best if I could disable it for specific file extensions    If anyone knows about this  that would be great

Would it be possible for you to use a special command for saving these files?

If you do :set binary, :w and :set nobinary the file will be written without newline if there was none to start with.

This sequence of commands could be put into a user defined command or a mapping, of course.

Maybe you could look at why they are complaining  If a php file has a newline after the ending     php will output it as part of the page  This is not a problem unless you try to send headers after the file is included   However  the    at the end of a php file is optional  No ending     no problem with a newline at the end of the file

I have not tried this option  but the following information is given in the vim help system  i e  help eol     endofline   eol    boolean  default on              local to buffer              not in Vi   When writing a file and this option is off and the  binary  option is on  no  lt EOL gt  will be written for the last line in the file   This option is automatically set when starting to edit a new file  unless the file does not have an  lt EOL gt  for the last line in the file  in which case it is reset         Normally you don t have to set or   reset this option   When  binary  is   off the value is not used when writing   the file   When  binary  is on it is   used to remember the presence of a    for the last line in the file    so that when you write the file the   situation from the original file can   be kept   But you can change it if you   want to    You may be interested in the answer to a previous question as well   Why should files end with a newline

Try to add in  vimrc set binary

I think I ve found a better solution than the accepted answer  The alternative solutions weren t working for me and I didn t want to have to work in binary mode all the time  Fortunately this seems to get the job done and I haven t encountered any nasty side-effects yet  preserve missing end-of-line at end of text files  I just added the whole thing to my    vimrc

And for vim 7 4  you can use  preferably on your  vimrc   thanks to     for that last bit of news     set nofixendofline  Now regarding older versions of vim  Even if the file was already saved with new lines at the end  vim -b file and once in vim   set noeol  wq  done  alternatively you can open files in vim with  e   bin file Yet another alternative   set binary  set noeol  wq  see more details at Why do I need vim in binary mode for   39 noeol  39  to work

There is another way to approach this if you are using Git for source control  Inspired by an answer here  I wrote my own filter for use in a gitattributes file   To install this filter  save it as noeol filter somewhere in your  PATH  make it executable  and run the following commands   git config --global filter noeol clean noeol filter git config --global filter noeol smudge cat   To start using the filter only for yourself  put the following line in your  GIT DIR info attributes     php filter noeol   This will make sure you do not commit any newline at eof in a  php file  no matter what Vim does   And now  the script itself      usr bin python    a filter that strips newline from last line of its stdin   if the last line is empty  leave it as-is  to make the operation idempotent   inspired by  https   stackoverflow com questions 1654021 how-can-i-delete-a-newline-if-it-is-the-last-character-in-a-file 1663283 1663283  import sys  if   name         main         try          pline   sys stdin next       except StopIteration            no input  nothing to do         sys exit 0         spit out all but the last line     for line in sys stdin          sys stdout write pline          pline   line        strip newline from last line before spitting it out     if len pline   gt  2 and pline endswith   r n            sys stdout write pline  -2       elif len pline   gt  1 and pline endswith   n            sys stdout write pline  -1       else          sys stdout write pline

Add the following command to your  vimrc to turn of the end-of-line option   autocmd FileType php setlocal noeol binary fileformat dos   However  PHP itself will ignore that last end-of-line - it shouldn t be an issue  I am almost certain that in your case there is something else which is adding the last newline character  or possibly there is a mixup with windows unix line ending types   n or  r n  etc    Update   An alternative solution might be to just add this line to your  vimrc   set fileformats  dos

I ve implemented Blixtor s suggestions with Perl and Python post-processing  either running inside Vim  if it is compiled with such language support   or via an external Perl script  It s available as the PreserveNoEOL plugin on vim org

User · Answer

OK  you being on Windows complicates things     As the  binary  option resets the  fileformat  option  and writing with  binary  set always writes with unix line endings   let s take out the big hammer and do it externally   How about defining an autocommand   help autocommand  for the BufWritePost event  This autocommand is executed after every time you write a whole buffer  In this autocommand call a small external tool  php  perl or whatever script  that strips off the last newline of the just written file   So this would look something like this and would go into your  vimrc file   autocmd     Remove all autocmds  for current group   see below  autocmd BufWritePost   php  your-script  lt afile gt    Be sure to read the whole vim documentation about autocommands if this is your first time dealing with autocommands  There are some caveats  e g  it s recommended to remove all autocmds in your  vimrc in case your  vimrc might get sourced multiple times
