====== Non-breaking Space Syntax PlugIn ====== ---- plugin ---- description: Use non-breaking spaces author : Matthias Watermann email : support@mwat.de type : syntax lastupdate : 2020-10-07 compatible : Frusterick Manners, Greebo, Hogfather depends : conflicts : similar : tags : typography downloadurl: https://github.com/turnermm/convenience/archive/nbsp.zip ---- ===== About ===== ==== Upgrade ==== The above download version has been updated to work with hogfather by --- [[user>turnermm|turnermm]] //2020-10-07 18:36//. Any issues go to the forum, not to turnermm. Note on upgrade to version 2020-10-07: On some machines it appeared necessary to disable and re-enable the plugin after the update. ---[[user>JoeT]] 2022-07-14 ==== Background ==== A so-called //non-breaking space//((NBSP: ISO-8859-1 char #160 and UTF-8 char-sequence #194#160)) is a character which is rendered visually just as the usual spaces((''space'': ASCII char #32 --- not to be confused with ''blanks'', ASCII char #255)) are. The whole point in using this unusual character (in­stead of an ordinary ''space'') is, that it is //not// considered a word delimiter. In other words: It's supposed to be handled like a normal character which just happens to have no visible points.((In consequence it will //not// be used to break lines (word wrap) and it won't get expanded if the renderer is going to justify text by moving words in a line of text.)) While the NBSP character is quite often abused for nothing more than de­sign pur­po­ses((which are usually dealt with better by use of CSS)) there are a few occasions for its legitimate use. Con­si­de­ring, how­ever, today's keyboards and/or writing habits, it's not that easy to actually type in the NBSP character where it's needed. This is especially true if one's going to write text which is to be stored in UTF-8 format((which is the default text format used for DokuWiki's pages)) because here are even //two// bytes used to represent the NBSP: byte #194 im­me­dia­te­ly fol­lo­wed by byte #160. While modern textprocessing software((e.g. [[http://www.openoffice.org/|OpenOffice.org]] and most GNU/Linux editors)) often supports UTF-8 characters, Do­ku­Wi­ki pages are usually written and edited using a simple web-browser with (X)HTML input forms where it can get quite difficult to insert such a cha­rac­ter((see the [[bomfix|BOMfix]] plugin for another way to edit)). --- This [[#Plugin Source|plugin]] tries to solve the problem. Note from the comments: You can get most of the effect of this by simply creating a ''conf/entities.local.conf'' file and adding a line like this to it: (nbsp)   Same way you can add %%(tab)%% for 3-4 spaces and using an indented paragraph. ===== Usage ===== The markup syntax implemented by this [[#Plugin Source|plugin]] is quite simple and looks like either \  (i.e. a ''backslash''((''backslash'': ASCII char #92)) character followed by a ''space'')((One could call this an "''escaped space''")) or ~~SP~~ (for those of you who'd rather a more expressive markup). Whenever one of the­se cha­rac­ter sequences((you may use whichever variant you like and may even mix them in the same page)) is found it will be replaced by the appropriate UTF-8 cha­rac­ters. That's all. Personally I'd recommend to use the first variant (i.e. ''__%%\ %%__'') as it both seems to be more intuitive and needs less characters to type and store. Both ways of mark­up, how­ever, are replaced by the UTF-8 character sequence exactly the same. ===== Installation ===== Search and install the plugin using the [[plugin:extension|Extension Manager]]. Refer to [[:Plugins]] on how to install plugins manually. * http://dev.mwat.de/dw/syntax_plugin_nbsp.zip ===== Plugin Source ===== Here comes the [[http://www.gnu.org/licenses/gpl.html|GPLed]] PHP source((The comments within the [[#Plugin Source|source]] file are suitable for the OSS [[http://www.stack.nl/~dimitri/doxygen/index.html|doxygen]] tool, a do­cu­men­ta­tion sy­stem for C++, C, Java, Ob­jec­tive-C, Python, IDL and to some extent PHP, C#, and D. --- Since I'm working with dif­fe­rent pro­gram­ming lan­gua­ges it's a great ease to have one tool that handles the docs for all of them.)) for those who'd like to scan it be­fore actu­ally in­stal­ling it: syntax_plugin_nbsp.php - A PHP4 class that provides the * ability to insert non-breaking spaces in DokuWiki page. * *

* To actually use this plugin just add \\ (i.e. backslash * space) or ~~SP~~ in a DokuWiki page. This will be expanded * to the UTF-8 character sequence. *

... * Before writing this little plugin I tried to use the file ''conf/custom.conf'' for this task. But this didn't work because for one reason or the other that file isn't used at all by DokuWiki (2005-07-13). ''Grep''ing the sources showed that the file isn't referenced anywhere. I dunno whether this is a bug or in­ten­ded be­ha­viour. ---- You can get most of the effect of this by simply creating a conf/entities.local.conf file and adding a line like this to it. -- //[[http://adam.shand.net/|Adam Shand]] 2007-01-29// > (nbsp)   I am new to DokuWiki (7days). I installed your plugin in a locally installed DokuWiki and a test one available on the net. Since then, when there is the letter "à" (à), this letter is replaced by a space or a question mark followed by a space according to the browser used. All my files are in UTF-8. The funny thing is that you are detecting the sequence "C2A0" and this letter is "C3A0" in UTF-8. You can have a look to the page http://carnetweb.info/wiki/doku.php?id=developement at the end of the line starting with "nbsp" there is the sequence "aàa". > Thanks for spotting this!

My intention (as stated in the source comment) was to replace chr(160) occurences which where not proper UTF-8 encoded. But, alas, it didn't come to my mind at that time, that chr(160) can be part of another UTF-8 sequence. So while your suggestion would (X)HTML encode the correct ''nbsp'' UTF-8 sequence (which is a good thing in itself) it does //not// was I intended in the first place, it's in fact the opposite: while I wanted to say "find all #160 that are //not// UTF-8 encoded" your proposal says "find #160 that //is// UTF-8 encoded". --- As about the chr(194) (0xC2): it was not supposed to "hanging on its own" as the RegEx means that chr(194) must not in front of chr(160) and, as Francois reported, the RegEx as such does do exactly that, with the unintended side effects he mentioned :-(\\ //--- [[support@mwat.de|Matthias Watermann]] 2005-09-26 07:44// >>> It was late :? (and I just realised there is no oops smiley in Dokuwiki) I went by the comments without paying enough attention to the regex. I guess you need a more complex pattern that attempts to match invalid UTF-8 byte sequences or do away with that pattern altogether. I guess from a conceptual point of view a plugin shouldn't really have to validate the byte sequence used in raw wiki page - especially when it is outside the syntax proposed by the plugin. --- //[[chris@jalakai.co.uk|Christopher Smith]] 2005-09-26 09:40// Had UTF-8 problems with this one.
