Remove empty lines from code

Hello. I can't find action in PHPStorm to remove empty lines from code.
I get project that have many empty lines that are unused.
If I run reformat code action this empty lines are not removed.
How to remove them from file ?

Hi,

maybe you can search for \n\n and Replace it by \n

It depends what kind of empty lines they are. Single empty line inside the code (function body etc) will most likely will never be removed as it is very often used to visually separate the code a bit, but things like double empty line, or multiple empty lines between methods etc can be removed if configured to do so -- make sure that you configured it at "Settings | Code Style | PHP | Blank Lines".

Also make sure that "Settings | Code Style | PHP | Wrapping and braces | Keep when reformatting | Line breaks" is unchecked -- it may affect other settings as well.

Other than that -- Replace \n\n by \n as suggested above (this will remove all empty lines).

After download code from server I get something like this below.
After everyline of code is one empty line. Code is mixed with css, html and PHP.
I am terribly annoyed with it and I can not imagine manually delete these empty rows:

I see. That's a bit different storry -- see this ticket: http://youtrack.jetbrains.com/issue/WI-9103

It seems that these empy lines are added by PhpStorm during file transfer (most likely when uploading to remote host).

Hi, anther developer was working on the project and he used FileZilla to download and upload files. when i connected remove host i found some files were having empty line like above.

i solved this with a trick

  1. First if pressed [ctrl]+[shift]+J to remove lines and created a single line code.
  2. Then I pressed [ctrl]+[alt]+L to reindent all the code.

The other options didn't work for me.  This removed empty lines using replace :

1. start replace ( command R )

2. select Regex replace

3. search for:    ^\s*^

4. replace with:   ( leave it empty )

5. click replace all.

 

explanation

^ ( carrot / shift 6 in regex == start of line )

\s* ( back slash s asterisk == any number of white space )

^\s*^ == start of line followed by any number of white space followed by start of line

^$ ( carrot followed by dollar sign ) == line with nothing
