Erasing blank lines

[xavekinho]

Hi, I like the EditDelLine command, but is there a similar command to erase all the blank lines of the active document?

Also, is there a simple command to erase all white spaces in the end of lines? This is because sometimes I paste a list in a txt file, but the source had one or a couple of blank spaces at the end of each line.

Thanks in advance!

1.) replace

Code: Select all

\n\n

by

Code: Select all

\n

(Regex!) repeatedly till it finds no more.

2.) there is an option to strip trailing whitespace on saving. You can set this per document class, go to Configure - Preferences - Document Classes - <yourdocumentclass>, then in the righthand side of the dialog search for the checkbox "Strip trailing spaces from lines when saving".

Could not find such Regular Expression! A piece of the text I was trying to apply was:

Code: Select all

        4  Standstill
        2  Umezawa's Jitte
//  29 other spells


//  Sideboard

SB:  3  Annul
SB:  1  Blue Elemental Blast
SB:  3  Engineered

To replace all trailing spaces at the end of line:

Search for: _*\n
Replace with: \n
( Using "_" to represent the space character )

---------------------------

To replace all blank liines:
Search for: \n\n
Replace with: \n

===========================================
Use the following settings:
-----------------------------------------
[X] Regular expression
Replace All
-----------------------------------------
Configure | Preferences | Editor
[X] Use POSIX regular expression syntax
-----------------------------------------

Like I said, for some reason it's not finding that regex..

To replace all trailing spaces at the end of line:

Search for: _*\n

( Using "_" to represent the space character )

Thanks!!

Maybe the blank lines are not blank?

Have you turned on visibility for all characters? Maybe spaces or tabs are there?

Have you tried to remove trailing spaces on the "blank lines" first? Remove the blank spaces on all lines, then try searching for \n\n. And make sure there are no leading/trailing spaces in the search phrase \n\n.

Hmm, that's it! There are actually tab spaces! But they aren't visible, so is there another trick to get get rid of all blank lines, including the ones with white spaces or tabs?

Find what: ^[ \t]*\n
Replace with: [nothing]

[X] Regular expression

Replace All

This ends the discussion!
Thanks!

Or you could search for

^[[:blank:]]*\n

saving you the 'hassle' of remembering what's a white space
