<php> <?php

  1. xmlWiki - MediaWiki XML Hack
  2. Nad - 2005-05-18
  3. TODO:
  4. - Move xwskin.php into xmlwiki dir, and make admin copy it into skins dir
  5. Security:
  6. - xml:article - holds article perms, it doesn't have perms of its own (owner, read-groups, write-groups)
  7. - xml:user - r/w by user, not currently used, but for xmlWiki prefs etc
  8. - sys:user - r/w by admin only, holds users groups and other system info like stats
  9. Publish:
  10. - xml:article - holds article publish-list
  11. Transforms:
  12. - xml:article - now transforms are in here (main article is now like <body>)
  13. - so we don't do the "its one of ours" thing anymore
  14. Raw as Default:
  15. - Need to mod the article-link so it has action=view
  1. LATER:
  2. - allow XIncludes to build large docs from others
  3. - allow docBook and DSSSL content
  4. - Maybe only use XML transforms and use PHP via PI's
  1. ---------------------------------------------------------------------------------------------------------------------- #
  2. INIT
  1. Exit if not included from index.php

defined('MEDIAWIKI') or die('xmlwiki.php must be included from MediaWiki\'s index.php!');

  1. TODO: ensure $_REQUEST['action'] is valid, unset if not
  2. otherwise, our hooks are bypassed
  1. Otherwise set up xmlWiki global environment ready for input and output processing

$xwEdit = isset($_REQUEST['action']) && ($_REQUEST['action'] == 'edit'); $xwView = (!isset($_REQUEST['action']) || (isset($_REQUEST['action']) && ($_REQUEST['action'] == 'view'))); $xwRaw = isset($_REQUEST['action']) && ($_REQUEST['action'] == 'raw'); $xwPreview = isset($_REQUEST['wpPreview']); $xwSave = isset($_REQUEST['wpSave']); $xwUserName = $wgUser->mName; $xwArticleTitle = $wgTitle->getPrefixedURL(); $xwArticleCache = array(); $xwArticleLinks = array(); $xwUserLinks = array(); $xwMessages = array();

  1. Get articles and attempt to Domificate

if ($xwArticle = $wgArticle->getContent(false)) xwDomificateArticle($xwArticle, $xwArticleTitle); if ($xwArticleXML = xwArticleContent("xml:$xwArticleTitle")) xwDomificateArticle($xwArticleXML, "xml:$xwArticleTitle"); if ($xwUserXML = xwArticleContent("xml:$xwUserName")) xwDomificateArticle($xwUserXML, "xml:$xwUserName"); if ($xwUserSYS = xwArticleContent("sys:$xwUserName")) xwDomificateArticle($xwUserSYS, "sys:$xwUserName");

  1. Security

if (ereg('^xml:(.+)$', $xwArticleTitle)) { # This is an xml-pseudo-namespace # - get perms from associated article/user } elseif (ereg('^sys:(.+)$', $xwArticleTitle)) { # This is an sys-pseudo-namespace # - only admin can read/write sys: } elseif (is_object($xwArticleXML)) { # Get perms from xml:article } else $xwReadable = $xwWritable = true;

  1. ---------------------------------------------------------------------------------------------------------------------- #
  2. INPUT
  1. No input processing for now
  2. - used later for custom edit forms (database table article will need it)
  1. Parse and process input from forms

function xwProcessInput() {

global $xwArticle, $xwArticleTitle, $xwReadable, $xwWritable; global $xwSave;

# If article is being updated, if ($xwSave) { #global $_POST; if (!$xwReadable || !$xwWritable) { # Not writable, change action to view xwMessage("I'm sorry Dave, I'm afraid I can't do that.", 'red'); global $action; $action='view'; } }

}

  1. ---------------------------------------------------------------------------------------------------------------------- #
  2. OUTPUT
  1. Generate new output to send back to browser
  2. - if article is not XML, then wikiOut is used

function xwProcessOutput() {


global $wgOut, $wgUser; global $xwArticle, $xwArticleXML, $xwArticleTitle, $xwReadable, $xwWritable; global $xwView, $xwPreview, $xwSave, $xwRaw, $xwUserLinks, $xwArticleLinks;

# First trap Wiki output and extract content and links (should use $ver like Admin Page) ob_start(); $wgUser->setOption('skin', 'xwskin'); $wgOut->output(); $wikiOut = ob_get_contents(); $xwUserLinks = preg_match('/id="p-personal"(.+?)<\/div>/s', $wikiOut, $m) ? xwExtractHrefs($m[1]) : array(); $xwArticleLinks = preg_match('/id="p-cactions"(.+?)<\/div>/s', $wikiOut, $m) ? xwExtractHrefs($m[1]) : array(); ob_end_clean();

# If no read-access, clear output if (!$xwReadable) { $wikiOut = $xwArticle = ; xwMessage('Unable to comply.', 'red'); }

# If no write-access, remove edit link if (!$xwWritable) unset($xwArticleLinks['Edit']);

# If Viewing, # - if DOM, transform else extract marked-up content from wikiOut

# save-match: (preg_match('/^(.+\\s*

)(.+)(<\\/p>\\s*.+)$/ms', $wikiOut, $m)) if ($xwView) { xwMessage('Viewing Page...'); if (is_object($xwArticle)) xwTransformArticle($xwArticle); else if (preg_match('/^(.+)(.+)(.+)$/ms', $wikiOut, $m)) $xwArticle = $m[2]; else xwMessage('xmlWiki couldn\'t match view-output!', 'red'); } # If Previewing, we can get our raw content from inside the <textarea> # old-match: (preg_match('/^(.+.+Remember.+saved!.+?<\\/p>)(.+?)(
.+)(.+)$/s', $wikiOut, $m)) elseif ($xwPreview) { xwMessage('Previewing Page...'); if (preg_match('/^.+(.+Remember.+saved!.+?<\\/p>)(.+?)(
.+<textarea.+?>\\s*(.+)<\\/textarea>.+).+$/s', $wikiOut, $m)) { xwDomificateArticle($xwArticle = html_entity_decode($m[4])); if (is_object($xwArticle)) { xwTransformArticle($xwArticle); $xwArticle = $m[1].$xwArticle.$m[3]; } else $xwArticle = $m[1].$m[2].$m[3]; } else xwMessage('xmlWiki couldn\'t match preview-output!', 'red'); } # If saving, check the publishing list # - pblish info should be in $articleMeta elseif (false && $xwSave && count($xwArticlePublish)) { xwMessage('Publishing...', 'purple'); xwTransformArticle($xwArticle, $xwArticleTitle); # Publish each item foreach ($xwArticlePublish as $url) { if ($FH = fopen($url, 'a')) { fwrite($FH, $xwArticle); fclose($FH); xwMessage("Article published to $url"); } else xwMessage("Failed to publish to $url", 'red'); } } else { # This is probably a special page # - we'll just extract the content and leave as-is if (preg_match('/^(.+)(.+)(.+)$/ms', $wikiOut, $m)) $xwArticle = $m[2]; else xwMessage('xmlWiki couldn\'t match special-output!', 'red'); } # Apply xmlwiki-environment-transforms to output unless 'raw' requested if (!$xwRaw) { xwTransformWikiMarkup(); xwTransformGeshi(); xwTransformAddMessages(); xwTransformPageLayout(); xwTransformPageStyle(); } # And finally, output the sunovabitch print $xwArticle; }

  1. ---------------------------------------------------------------------------------------------------------------------- #
  2. ARTICLE FUNCTIONS
  1. Retreive wiki-article as raw text

function xwArticleContent($articleTitle) { # Return with results if already cached global $xwArticleCache; if (isset($xwArticleCache[$articleTitle])) return $xwArticleCache[$articleTitle]; # Get wiki article content (or use global if no article passed) if ($article = new Article(Title::newFromText($articleTitle))) $article = $article->getContent(false); if ($article == '(There is currently no text in this page)') return false; if ($articleTitle) $xwArticleCache[$articleTitle] = $article; return $article; }

  1. Decide kind of article from content and title

function xwArticleType($title, $article) { # Name based matches if (ereg('\\.php$', $title)) return 'php'; if (ereg('\\.css$', $title)) return 'css'; if (ereg('\\.as$', $title)) return 'actionscript'; if (ereg('\\.py$', $title)) return 'python'; if (ereg('\\.java$', $title)) return 'java'; if (ereg('\\.(cpp)|(h)$', $title)) return 'cpp'; if (ereg('\\.js$', $title)) return 'javascript'; if (ereg('\\.css$', $title)) return 'css'; # Content based matches if (preg_match('/^<\\?xml.+?\\?>\\s*<xsl:stylesheet/', $article)) return 'xslt'; if (ereg('^<\\?xml', $article)) return 'xml'; if (ereg('^<\\?html', $article)) return 'html4strict'; if (ereg('^#![/a-zA-Z0-9]+\\/perl', $article)) return 'perl'; if (ereg('^#![/a-zA-Z0-9]+sh', $article)) return 'bash'; }

  1. Convert passed article to a DOM object
  2. - Article is unchanged if not valid XML

function xwDomificateArticle(&$article, $id = ) { xwMessage("Domificating $id"); ob_start(); if ($dom = domxml_open_mem($article)) $article = $dom; else { # Could not convert, extract error messages from output xwMessage("   Failed :-(", 'red'); $err = preg_replace("/<.+?>/", "", ob_get_contents()); $err = preg_replace('/ in .+? on line.+?[0-9]+/', , $err); $err = preg_replace('/Warning.+?\\(\\): /', , $err); foreach (split("\n", $err) as $msg) if ($msg) xwMessage("   $msg", 'red'); } ob_end_clean(); }

  1. Reduce article to a string if it's a DOM object
  2. - ie if all xslt's had xml-output-method

function xwUndomificateArticle(&$article, $id = ) { if (!is_object($article)) return false; xwMessage("Undomificating $id"); # Validate, report errors # xwApplyXSLT($article, $xslt) if xml referrs one # Convert DOM back to XML if still an object if (is_object($article)) $article = $article->dump_mem(true); return true; }

  1. Apply XSLT to article-dom
  2. - if output-method is html, article will get stringified

function xwApplyXSLT(&$article, &$xslt) { xwMessage('Processing XSLT'); ob_start(); $tObject = domxml_xslt_stylesheet($xslt); $tResult = $tObject->process($article); # If output-method is html, use XSLT's dump_mem to create an html-string if (preg_match('/<xsl:output +?method *= *"html"/i', $xslt)) $tResult = $tObject->result_dump_mem($tResult); $err = preg_replace("/<.+?>/", "", ob_get_contents()); $err = preg_replace('/ in .+? on line.+?[0-9]+/', , $err); $err = preg_replace('/Warning.+?\\(\\): /', , $err); foreach (split("\n", $err) as $msg) if ($msg) xwMessage("   $msg", 'red'); ob_end_clean(); if ($tResult) $article = $tResult; else return false; return true; }

  1. Transform an article object
  2. - Article must be an xmlwiki:* DOM object to be transformable
  3. - Article is undomificated if DOM but not xmlwiki:*
  4. - Article remains unchanged if not DOM

function xwTransformArticle(&$article) { # Get doc info or exit if not one of ours if (!is_object($article)) return false; $aType = $article->doctype(); $aType = $aType->name; $aRoot = $article->document_element(); if (!ereg('^xmlwiki:', $aType)) return false; # this must change to meta article xwMessage("Transforming doctype \"$aType\""); # Loop thru transforms applying each foreach ($aRoot->get_elements_by_tagname('transform') as $tElement) { $tName = $tElement->get_content(); if (ereg('^(.+)\\(\\)$', $tName, $m)) { # Transform is "name()" format, try to execute from a local function declaration # - probably this is not needed soon, only accept article-transforms $tName = $m[1]; if ($tResult = @call_user_func("xwTransform_$tName", $article)) $article = $tResult; else xwMessage("   Unknown transform \"$tName\"!", 'red'); } else { # Get transform-article and apply to $article if ($tText = xwArticleContent($tName)) { # Get transform type $tType = xwArticleType($tName, $tText); if ($tType == 'xslt') xwApplyXSLT($article, $tText); elseif ($tType == 'php') { # php, check perms and execute (trapping errors for reporting - unless fatal) if ($perms_check_out_ok) { ob_start(); eval($tText); $err = preg_replace("/<.+?>/", "", ob_get_contents()); foreach (split("\n", $err) as $msg) if ($msg) xwMessage($msg, 'red'); ob_end_clean(); } } elseif ($tType == 'css') { # include CSS ref in content } } else xwMessage("   No such transform-article \"$tName\"!", 'red'); } } # If article is still a DOM object, stringify it again xwUndomificateArticle($article); return true; }

  1. ---------------------------------------------------------------------------------------------------------------------- #
  2. TRANSFORMS
  3. - these transforms are only temporarily here - they should be articles
  4. - we should use DTD's for each kind: document, image, layout, table
  1. Do wiki markup on content

function xwTransformWikiMarkup() { }

  1. Include Geshi syntax highlighting
  2. NOTE: Geshi can be installed the normal way too now!
  3. because transforms don't use wikiOut

function xwTransformGeshi() { return; global $xwArticle, $xwArticleTitle; # First check for entire article highlighting # Highlight entire article if xwLang has been set if ($xwLang) { $xwGeshi = new GeSHi($xwArticle, $xwLang, "extensions/geshi/geshi"); $xwGeshi->set_tab_width(4); $geshi->set_keywords_style(1, 'font-weight: 100;', true); #$geshi->set_comments_style #$geshi->set_escape_char_style #$geshi->set_brackets_style #$geshi->set_strings_style #$geshi->set_numbers_style #$geshi->set_methods_style #$geshi->set_symbols_style #$geshi->set_regexps_style #$geshi->set_script_style #$xwArticle = $xwGeshi->parse_code(); } }

  1. Append messages to content

function xwTransformAddMessages() { global $xwArticle, $xwMessages; $xwArticle .= join("\n", $xwMessages); }

  1. This is the default postTransform which surrounds the page
  2. - most transforms do not reference the global-current-article like this one
  3. - this is a special transform, because it affects all pages, even special pages

function xwTransformPageLayout() { global $xwArticle, $xwArticleTitle, $xwUserLinks, $xwArticleLinks; xwMessage("Hi defaultTransform here :-)"); $xwArticle = "

xmlWiki - $xwArticleTitle
".join('
',$xwArticleLinks)."
\"xmlWiki\"
$xwArticleTitle
$xwArticle

"; }

  1. Apply styling to page

function xwTransformPageStyle() { global $xwArticle; $xwArticle = preg_replace("/(

)(.+?)(<\\/p>)/", '

   $2   

', $xwArticle);

}

function xwTransform_document_xxx() { # documents are built from parts, # the parts are a tree in its body # includes 'edit' link for each (like section, and also like table) }

  1. A document object is finalised by transforming it to its body's text

function xwTransform_document_render() { global $xwArticle; $root = $xwArticle->document_element(); $body = $root->get_elements_by_tagname('body'); if (count($body)) $xwArticle = $body[0]->dump_mem(true); }

function xwTransform_layout_xxx() { # for layout container style article }

function xwTransform_image_xxx() { # object contains properties for loading and transforming an image # image needs no body # Get the global image on which imageTransforms work global $xwArticleImage; }

  1. Converts the in-memory-working image into article content

function xwTransform_image_render() { global $xwArticle, $xwArticleTitle, $xwArticleImage, $xwRaw; if ($xwRaw) { # render article directly if 'raw' request imagePng($xwArticleImage); # Clear article or it will render as xml $xwArticle = ; # set header to image header("Content-type: image/png"); }

else { # the raw image is not being requested, render image in-page with info instead $xwArticle = "<img src=\"$xwArticleTitle?action=raw\" alt=\"$xwArticleTitle\"/>"; } }

  1. A table object is an interface to a database table
  2. - this can't be implimented fully until the 'edit' hook is done
  3. - the query result is a list in document body, so any normal document transforms can follow it

function xwTransform_table_xxx() { # - view lists the table/result with links to edit each (like a normal composition-doc) # - also form for create/edit/edlete # - result rows are in document body (just like a content-tree in a document would be)

# NODE-LIKE-DB

# - if all tables have GUID for pri-key, # - and all have time/duration (or cycle?), # - and we have master list of cols-to-table # - then we could create a meta-query (resulting in pri-key-list of all matches)

}

  1. Transform the body content to a xtml/javascript tree

function xwTransform_tree() { # import php-tree-component }

  1. ---------------------------------------------------------------------------------------------------------------------- #
  2. UTILITY FUNCTIONS
  1. Return a list of the hrefs found in the passed content

function xwExtractHrefs($content) { preg_match_all('/(<a.+?>(.+)<\/a>)/', $content, $match); $hrefs = array();

for ($i = 0; $i < count($match[0]); $i++) $hrefs[$match[2][$i]] = $match[1][$i]; return $hrefs; }

  1. Add message to queue

function xwMessage($msg, $col = 'blue') { global $xwMessages;

return $xwMessages[] = "

$msg

\n";

}
