=====The Cross Syntax Cheat Sheet: DokuWiki versus AsciiDoc Markups=====

====Introduction====
At time of writing, [[http://docs.slackware.com/|SlackDocs]] uses a DokuWiki engine to convert the wiki pages (plain text including markup) to xhtml text.

Converting the DokuWiki markup to AsciiDoc markup can ease the work of translators of DokuWiki pages, as the application po4a, that allows to produce PO files ready for translation, can handle the AsciiDoc markup but not the DokuWiki markup.

This conversion should be "bi-directional":

DokuWiki source page => AsciiDoc source page => PO file => Translated PO file => AsciiDoc translated page => Dokuwiki translated page.

The ''convtags'' converter written by Didier Spaier is available [[http://slint.fr/misc/convtags|here]]. This converter takes the form of a set of UTF-8 encoded sed scripts. For instance to convert a page from this wiki to AsciiDoc, display the result in Firefox, translate it then convert it back to DokuWiki:
  * create a new (empty) text file
  * click "edit this page" or "show pagesource" in the page you want to convert and translate
  * select the whole source text with Ctrl+Shift+A
  * copy and paste it in the text file
  * save the text file as e.g. ''genuine.txt'' then run:<code>
convtags da genuine.txt genuine.asc # convert to AsciiDoc
convtags aw genuine.asc genuine.html # if you want to make a static web page (to run this command you need AsciiDoc) 
firefox genuine.html # if you want to check the rendering of the static web page
po4a-gettextize -f asciidoc -m genuine.asc -M UTF8 -p genuine.po # to make a PO file containing only the text to translate
lokalize genuine.po # to translate. You could also use emacs or vim in PO mode, or poedit available @ slackbuilds.org
po4a-translate -f asciidoc -m genuine.asc -p genuine.po -l translated.asc # to make an asciidoc file from your translation 
convtags ad translated.asc translated.txt # convert back your translation to DokuWiki
</code>
You can then copy/paste the text of translated.txt as the source of the translated page. 

Asciidoc and Firefox are included in a full Slackware installation.\\
In addition, you will need to make and install a package [[http://slackbuilds.org/repository/14.1/development/source-highlight/|source-highlight]].

There are some limitations to the conversion from DokuWiki to AsciiDoc, see the [[http://slint.fr/misc/convtags/README|README]].

In addition to easing the translation, the converter could be used e.g. to convert a static website build from AsciiDoc source pages to a Wiki powered by DokuWiki or reverse.

The table below summarizes the rules set up for the conversion.

This table can **not** be used as an AsciiDoc Cheat Sheet because it includes only the markup needed for bi-directional conversion: the AsciiDoc syntax is far richer. This also implies that only this subset of the Asciidoc markup can be automatically converted to DokuWiki.

A few DokuWiki markups are not included in the table because they have no direct counterpart in AsciiDoc.

Setting this conversion table was not straightforward as AsciiDoc lacks a "real" formal definition of its syntax in the [[http://www.methods.co.nz/asciidoc/userguide.html|AsciiDoc User Guide]] and even worse the [[http://docs.slackware.com/wiki:syntax|DokuWiki formatting syntax]] just provides examples.

In the "Notes" column, D: stands for DokuWiki and A: for AsciiDoc.

|**Item** |**Dokuwiki**|**Asciidoc**|**Notes**|
|Emphasized     | %%//%%  |%%__%% | D: rendered as //italic//. Does not span across paragraphs.((If used across paragraphs, merges them. I consider this as a bug in DokuWiki -- Didier Spaier.)) \\ Several text decorations (emphasized, strong, monospaced, underlined, strike through) can be nested in both syntax. Quoting cannot be overlapped. |
|Strong         | %%**%%  | %%**%%            | D: rendered as **bold**. Does not span across paragraphs.|
|Monospaced     | %%''%% | ++|A: other syntax ` but only on word boundaries, implies no further expansion. \\ Does not span across paragraphs.|

|Double quotation marks| %%"text"%% | %%``text''%%|Rendering: “text”((“ is U+201C, ” is U+201D)). \\ D: replacement depends on 'typography' setting in configuration file.\\  A: only on word boundaries, no span across paragraphs.|
|Single quotation marks   | %%'text'%%   | %%`text'%%  |Rendering: ‘text’((‘ is U+2018,  ’ is U+2019)). \\ D: replacement depends on 'typography' setting in configuration file.\\  A: only on word boundaries, no span across paragraphs.|
|No formatting (passthrough)   | <nowiki>%%text with markup%%</nowiki> or: \\ %%<nowiki>text with markup</nowiki>%%| %%$$text with markup$$%%|A: provides also a  syntax for passthrough blocks of text, but useless for the conversion, as practically in Dokuwiki the markup should not span over paragraphs((Because that results in a merge of these paragraphs)) |
