I've reviewed this plugin's code, and there is one major issue with it, namely this line: system("hnb '$params{page}.hnb' 'go root' 'export_html $tmp' > /dev/null"); This could potentially allow execution of artibtary shell code, if the filename contains a single quote. Which ikiwiki doesn't allow by default, but I prefer to never involve a shell where one is not needed. The otl plugin is a good example of how to safely fork a child process without involving the shell. Other problems: * Use of shell mktemp from perl is suboptimal. File::Temp would be better. * The htmlize hook should not operate on the contents of `$params{page}.hnb`. The content that needs to be htmlized is passed in to the hook in `$params{content}`. If these problems are resolved and a copyright statement is added to the file, I'd be willing to include this plugin in ikiwiki. --[[Joey]]
