| io_sweepNS($id, $basedir = 'datadir') X-Ref |
| Removes empty directories Sends IO_NAMESPACE_DELETED events for 'pages' and 'media' namespaces. Event data: $data[0] ns: The colon separated namespace path minus the trailing page name. $data[1] ns_type: 'pages' or 'media' namespace tree. param: string $id - a pageid, the namespace of that id will be tried to deleted param: string $basedir - the config name of the type to delete (datadir or mediadir usally) return: bool - true if at least one namespace was deleted author: Andreas Gohr <andi@splitbrain.org> author: Ben Coburn <btcoburn@silicodon.net> |
| io_readWikiPage($file, $id, $rev = false) X-Ref |
| Used to read in a DokuWiki page from file, and send IO_WIKIPAGE_READ events. Generates the action event which delegates to io_readFile(). Action plugins are allowed to modify the page content in transit. The file path should not be changed. Event data: $data[0] The raw arguments for io_readFile as an array. $data[1] ns: The colon separated namespace path minus the trailing page name. (false if root ns) $data[2] page_name: The wiki page name. $data[3] rev: The page revision, false for current wiki pages. param: string $file filename param: string $id page id param: bool|int|string $rev revision timestamp return: string author: Ben Coburn <btcoburn@silicodon.net> |

| io_readFile($file, $clean = true) X-Ref |
| Returns content of $file as cleaned string. Uses gzip if extension is .gz If you want to use the returned value in unserialize be sure to set $clean to false! param: string $file filename param: bool $clean return: string|bool the file contents or false on error author: Andreas Gohr <andi@splitbrain.org> |
| bzfile($file, $array = false) X-Ref |

| io_writeWikiPage($file, $content, $id, $rev = false) X-Ref |
| Used to write out a DokuWiki page to file, and send IO_WIKIPAGE_WRITE events. This generates an action event and delegates to io_saveFile(). Action plugins are allowed to modify the page content in transit. The file path should not be changed. (The append parameter is set to false.) Event data: $data[0] The raw arguments for io_saveFile as an array. $data[1] ns: The colon separated namespace path minus the trailing page name.

| _io_saveFile($file, $content, $append) X-Ref |
| Internal function to save contents to a file. param: string $file filename path to file param: string $content param: bool $append return: bool true on success, otherwise false author: Andreas Gohr <andi@splitbrain.org> |
| io_saveFile($file, $content, $append = false) X-Ref |
| Saves $content to $file. If the third parameter is set to true the given content will be appended. Uses gzip if extension is .gz and bz2 if extension is .bz2 param: string $file filename path to file param: string $content param: bool $append return: bool true on success, otherwise false author: Andreas Gohr <andi@splitbrain.org> |
| io_replaceInFile($file, $oldline, $newline, $regex = false, $maxlines = 0) X-Ref |
| Replace one or more occurrences of a line in a file. The default, when $maxlines is 0 is to delete all matching lines then append a single line. A regex that matches any part of the line will remove the entire line in this mode. Captures in $newline are not available. Otherwise each line is matched and replaced individually, up to the first $maxlines lines or all lines if $maxlines is -1. If $regex is true then captures can be used in $newline. Be sure to include the trailing newline in $oldline when replacing entire lines.
