I am using 2.0.5.1 on a windows XP OS. I have MikTeX 2.9 installed.

I am trying to use the needspace package. As such I have opened MikTex installed it , then refreshed FNDB via the 'Settings' in admin mode.

I then open LyX, load my document and have entered 

\usepackage{needspace}
\needspace{5\baselineskip}

in the preamble and hit the 'reconfigure' option in Lyx.

Problem is it appears that Lyx does not 'register' the needspace package as my lines are running over pages etc.

My question is how would I apply the \needspace{5\baselineskip} to the whole document so that LyX knows that I dont want paragraphs drifting between pages...either the paragraph stops before the end of a page or starts on a new page if the space is less than 5

    You need to place the \needspace{5\baselineskip} LaTeX macro where you need it, not in the preamble... – Werner Aug 16 '13 at 06:27
  • Thanks for reply ...is there anyway of applying this to the whole document ?? it seems like I could just use 'clear page' or something ?? – barsil sil Aug 16 '13 at 06:40
  • Note that you do need to run reconfigure in LyX after you add a package but (assuming you already did that) running reconfigure after you edit the preamble does nothing. – scottkosty Aug 16 '13 at 08:29

    @barsilsil So that @Werner sees your message, you need to address it to him. Put @Werner at the start of your comment. – scottkosty Aug 16 '13 at 08:30

  • @scottkosty I have done all the usual things that are normally recommended for installing a package via MikTex. My question is how would I apply the \needspace{5\baselineskip} to the whole document so that Lyx knows that I dont want paragraphs drifting between pages...either the paragraph stops before the end of a page or starts on a new page if the space is less than 5 – barsil sil Aug 16 '13 at 09:33
  • @barsilsil: You could try \everypar{\needspace{5\baselineskip}}; not tested though... – Werner Aug 16 '13 at 12:37
  • @Werner Tried it in the preamble ...no effect and then I placed it at the beginning of the document and it seemed to take out the pdf viewer, which returned after deleting the ERT and restarting – barsil sil Aug 16 '13 at 13:02
  • @Werner...my noob guess is something via the Local Layout Tab ...but i am too much of a beginner to attempt at the moment. – barsil sil Aug 16 '13 at 13:31

Using \needspace before a paragraph can't be done with \everypar, because the tokens in \everypar are inserted after the paragraph has started.

You need to set \clubpenalties, rather than \widowpenalties, if you want that a paragraph is split across pages only after the fifth line:

\clubpenalties 5 10000 10000 10000 10000 0

and, of course, 

\raggedbottom

With the first line (in the document preamble), TeX will insert infinite penalties between the first five lines, and no penalty after the fifth line and onwards. The normal setting of \clubpenalty will be overridden, but not the setting of \widowpenalty, so this will discourage splitting before the last line nonetheless.

The \raggedbottom declaration is in force with the standard classes in oneside mode, so it's necessary only for the twoside mode, where this setting of paragraphs would be dubious anyway.

  • So \clubpenalities <N> <val1> <val2> ... <valN> refers to a \clubpenalty of <val1> if the paragraph is broken exactly after the first line; <val2> if the paragraph is broken exactly after the second line; ... <valN> if the paragraph is broken exactly after the Nth line? TeX by Topic just lists \clubpenalty. – Werner Sep 17 '13 at 22:28
  • @Werner Yes; and the last specification is repeated as many times as needed. This is an e-TeX extension and is not covered in TeX by Topic and the TeXbook, but texdoc etex is your friend. – egreg Sep 17 '13 at 22:29
