This works. Something I do in my config or css must be interfering. Below is a Markup example to show that it works.

Avatar is the result of many years of work and play by
literally hundreds of people.  We hope that you enjoy
playing the game as much as we have enjoyed creating it.


The game offers fun to the beginner and has enough
complexity to keep the expert challenged.  One of the
most important aspects of the game is the interaction
between the players.  The players make this game.

The game is based on many "dungeon games" that have
come before it and adds many new ideas.  There is no
absolute goal to the game; the players generally make
their own goals.  You will probably pick and change
goals throughout your lifetime in the game.

Don't delete the markup markup. It differentiates content from the example.  -- gnuzoo April 24, 2024, at 07:30 PM
HansB: gnuzoo, the script enabled here is not the same as my latest version. It also does not quite work, see my example below. If you have trouble on your site please check the skin css. What skin do you use? Might it work with pmwiki standard skin (no $Skin var set)?

Here whitespace-php7.phpΔ is enabled. --Petko April 24, 2024, at 07:13 AM
This version has some differences to the newest updated whitespace.phpΔ --HansB

HansB: I am confused as to what version is enabled where: the Talk page and the Recipe page.
The whitespace-php7.php version was enabled on LiteralWhiteSpace, now also here on the talk page. It has some line-height and spacing configured that don't match what is enabled in the skin, so the lines in your table cells were not aligned. Here are the corrected styles. --Petko April 24, 2024, at 10:31 AM

 $HTMLStylesFmt['vspace'] = "  
  .halfline { height: 10px; font-size: 10px; line-height: 1;}
  .vspace { margin-top:0; line-height: inherit; }
  ";

HansB: thanks Petko! But the whitespace-php7.php version does not contain the fix I added for th ebug which adds an extra empty line above if the paragraph starts with a  text indent (empty space(s) at start of line). I fixed that in version 2024-03-17. And in the latest I tried to fix vertical spacing for extra empty lines, and tried to get vspace alignment more precise. But yes, it depends a lot on the skin css as well. I include example here [and what produces the grey stroke lines when half-line markup >>-<< is used? I also switched in the vspace markup definition <p class='vspace'>&nbsp;</p> to <div class='vspace'></div>, which I am not sure is an improvement or not (avoiding the &nsp; additions):
Using table with two cells. There should be line alignment.

(:table:)
(:cell:)
1
2
3
4
5
6
7
8
9
10
11
(:cell:)
1. first text line
2. second text line

   4. third indented text line, one empty line above


7. two empty lines above
>>-<<
9. half height empty line above
>>-<<
10. half height empty line above
(:tableend:) 

 if (@$MarkupFrame[0]['is'][$depth] == $icol) { echo "depth=$depth";

Please fix this. --gnuzoo April 12, 2024, at 03:35 AM
HansB: thanks for noticing. removed that debug snippet. 2024-04-12

> bug which adds an extra empty line if a new paragraph after an empty line starts with empty spaces at the beginning of the line.
Instead of solving the problem of not having to use ugly markup all over the place, this recipe bug introduces too much whitespace which can be just as annoying and impossible to remove.  Petko, can you please fix this bug? --gnuzoo March 12, 2024, at 08:03 PM
HansB: Fixed with latest update. 2024-03-17

I put 2 paragaphs under "Normal text ↑" in the sandbox on the main page and it puts too much vertical whitespace in front of the 2 paragraphs. --gnuzoo March 18, 2024, at 06:20 PM
HansB: PmWiki adds vertical space under heading 4 !!!!Normal Text, and you add an extra empty line space, therefore you got too much vspace. - 2024-04-24

diff whitespace.php whitespace.bak 
27c27
< Markup('^ws', '<^img', '/^(\\s+)(.*?)/', "WSIndent2($m[1])");
---
> Markup('^ws', '<^img', '/^(\\s+)(.*?)/e', "WSIndent2('$1')");

< Markup('spacing', '>style', "/(\\s{2,7})(?![^<]*>)/", "WSReplace($m[1])");
---
> Markup('spacing', '>style', "/(\\s{2,7})(?![^<]*>)/e", "WSReplace('$1')");

update: spoke too soon. Will have to revisit
(Ross Grady, Nov 8, 2015)
You probably don't need to quote $m[1], see the corrected lines of code. --Petko November 08, 2015, at 11:50 AM

Near the middle of this script there is a commented out line of code:

    # honour empty lines
    #Markup(':vspace', 'fulltext','/<:vspace>/',"<p class='vspace'>&nbsp;</p>");

Why is this commented out?  PMWiki does not allow more than 1 break. (PITS 1503) Do you know how to fix that? --gnuzoo April 20, 2024, at 08:17 PM
HansB: Fixed in update 2024-04-24

It would be really nice if this recipe defined a new markups to turn itself on and off for pages or sections of pages.  Or does it does do this already, and I'm just missing it?  Francis

How can I paste content into a page, which originates from emails and word processors, where text spacing is achieved by using spaces, tabs and empty lines?

• Well, you can also use [@preformatted text block@] markup if this is all you want to do - you don't need this recipe. See the text formatting rules.        Francis

Is there any way to use this recipe (or any other recipe for that matter) on certain pages only? I love the recipe and have been waiting for something like that for a long time, but I only need it on specific pages.

See GroupCustomizations. It also explains per page customisations. You would need to include the recipe on  a local Group.PageName.php file. HansB

--- Thanks.

Also, I tried pasting a formatted, tabbed text from a word document and the formatting was not even close to the original. Am I missing something ?? G.
