PlantUML Remote don't work but I patch the code

[gmarchand]

Hi

i patch the code

You have to modify default.php with this conf

$conf['remote_url']='http://plantuml.com/plantuml/img/';

and modify syntax.php with

    /**
     * Render the output remotely at plantuml.no-ip.org
     */
    function _remote($data, $in, $out) {
        if (!file_exists($in)) {
            dbglog($in, 'No such plantuml input file');
            return false;
        }

        $http = new DokuHTTPClient();
        $http->timeout = 30;

        $remote_url = $this->getConf('remote_url');
        // strip trailing "/" if present
        $base_url = preg_replace('/(.+?)\/$/', '$1', $remote_url);

        $java = $this->getConf('java');
        if ($java) {
            // use url compression if java is available
            $jar = $this->getConf('jar');
            $jar = realpath($jar);
            $jar = escapeshellarg($jar);

            $command = $java;
            $command .= ' -Djava.awt.headless=true';
            $command .= ' -Dfile.encoding=UTF-8';
            $command .= " -jar $jar";
            $command .= ' -charset UTF-8';
            $command .= ' -encodeurl';
            $command .= ' ' . escapeshellarg($in);
            $command .= ' 2>&1';

            $encoded = exec($command, $output, $return_value);

            if ($return_value == 0) {
               $url = "$base_url/image/$encoded"; 
            } else {
                dbglog(join("\n", $output), "Encoding url failed: $command");
