CMlyst is a Web Content Management System built using Cutelyst, it was initially inspired by WordPress and then Ghost. So it’s a mixture of both.
Two years ago I did it’s first release, and since them I’ve been slowly improving it, it’s been on production for that long providing www.cutelyst.org web site/blog. The 0.2.0 release was a silent one which marks the transition from QSettings storage to sqlite.
Storing content on QSettings is at first quite interesting since it’s easy to use but it showed not suitable very fast, first it kept leaving .lock files, then it’s not very fast to access so I had used a cache with all data, and a notifier updated that when something changed on the directory, but this also didn’t properly triggered QFileSystemWatcher so once a new page was out the cache wasn’t properly updated.
Once it was ported to sqlite, I decided to study how Ghost worked, this was mainly due many Qt/KDE developer switching to it. Ghost is quite simplistic, so it was very easy to try to provide something quite compatible with it, porting a Ghost theme to CMlyst requires very little changes due it’s syntax being close to Grantlee/Django.
Due porting to sqlite it also became clear that an export/import tool was needed, so you can now import/export it in JSON format, pretty close to Ghost, actually you can even import all you Ghost pages with it, but the opposite won’t work, and that’s because we store pages as HTML not Markdown, my feeling about markdown is that it is simple to use, convenient to geeks but it’s yet another thing to teach users which can simply use a WYSIWYG editor.
Security wise you need to be sure that both Markdown and HTML are safe, and CMlyst doesn’t do this, so if you put it on production be sure that only users that know what they are doing use it, you can even break the layout with a not closed tag.
But don’t worry, I’m working on a fix for this, html-qt is a WHATWG HTML5 specification parser, mostly complete, but the part to have a DOM, is not done yet, with it, I can make sure the HTML won’t break layout and remove unsafe tags.
Feature wise, CMlyst has 80% of Ghost features, if you like it please help add missing features to Admin page.
