[ANN] MorphicDoc : A project to document Morphic

by kilon alios

One of the frequent questions we get asked is how to use Morphic. Unfortunately there is very little documentation for Morphic around and barely touches the most interesting concepts. I decided to start my own project called MorphicDoc . MorphicDoc is very easy to install with Configuration Browser and it works in 2 ways. a) open the Help tool (World Menu => Help => Help Browser ) and there you will find a new section called "Morphic Doc by Kilon" b) open System Browser go to MorphicDoc package and look at the class side of MorphicDocExamples class , each method is an example taken from the tutorial in help tool and you can easily execute by clicking the green arrow next to its name. Right now only 3 pages have been added but slowly and steadily more will be added. To get new pages and even new chapters make sure you reinstall the same very simple way like installing just open Configuration Browser and click "Install Stable Version" after you selected MorphicDoc. I will try to add 1 page per day and at least 1 page per week depending on my free time. So make sure you update at least once per week to get the latest version of MorphicDoc. You can report issues , advice and requests at the project page in https://github.com/kilon/MorphicDoc. Of course pull requests are more than welcomed.

Metadata is in JSON at the start of the content file. - I use Seaside's HTML rendition engine. Entire site is rendered in Smalltalk code, like how a Seaside application does. Currently calls out to the Discount C library's executable through PipeableOSProcess to get HTML from the Markdown content. I seem to recall that Petit Markdown exists, but haven't tried it. - I found Seaside's HTML-in-code style not so convenient when trying to implement one particular fine looking open source Bootstrap skin. Maybe using a templating mechanism like Mustache will make it easier. - Because my site is small, SmallCMS1 reads the entire content directory tree into a tree-like (duh) structure. URLs are matched by walking the in-memory tree using simple string matching. I was going to say this prevents the dot dot trick, but I thought I'd verify. Putting a halt in my code, I now notice that Firefox processes ".." before it sends the request, so SmallCMS1 doesn't see the ".." at all, at least when using Firefox. - Comment system is outsourced to Disqus. - I VNC into the image and use inspectors, workspaces, and browsers as SmallCMS1's admin interface. I run my own VPS so I have Unix command line access to the content directory. SmallCMS1 is thus quite tied to the way I work. I have not published SmallCMS1. Maybe SmallCMS2, if it ever happens... :-) Pierce

I appreciate GitHub's issue tracker. However, I'm not ready to move development to Git right now. And having only issues on github feels strange. Moreover, I think having the list of projects on pillar's website is clearer. Something you could do however is to add links for each project in the todo: these links go target mailing list discussions (or a github tracker or both if we go that way). -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm." --Winston Churchill

Superb Now what would be great is to continue to story to make sure that Pharo and roassal can be used for real. Having a streaming API for files is apparently a first step.
