Martin Fowler and Markus Völter on DSLs

Martin Fowler and Markus Völter on DSLs - JAOO Conference Somewhat interesting discussion by some DSL leaders. There is a small bias around a specific vendor's software, but interesting to listen too.

What they talked about, my notes:
DSLs:
- Internal
- External
- IDE/Language Workbench
- MDA is vaporware
Eclipse GMF/EMF/Textual Languages
CASE Tools, COBOL, Fantasy that programmers are not needed.
Levels of DSL/DSM tooling - Documentation/Testing/Execution
Custom Syntax (External DSL) vs Internal Syntax (Internal DSL , Lisp/Ruby)
Method Chaining, Cool!
1 notation or many notations
(Excel, Boxes and Lines, etc) Power in how to combine the notations.
Divergence, Experimentation, and then Convergence.
UML is not a factor, so they think.

Here is the book in progress that Martin Fowler references, it was in draft form at time of my writing this post. Fowler's DSL book draft

Configuring Javascript SyntaxHighligher 3+ in a Blogger site

Image
In this post I tactically outline a quality way to configure the Javascript based SyntaxHighlighter library into a Blogger site. The configuration below makes use of the recent autoloader available in version 3 and greater of the SyntaxHighlighter.  The configuration code below is in fact using the SyntaxHighlighter which incidentally allows you to copy the code examples quickly.  Check out this very popular library here . Configuration: 1.  Login into blogger.com and click/select the site you want to configure ( http://www.blogger.com/home ) to support syntax highlighting.  Generally if there are multiple sites you would like to enable each site's template will need to be configured individually. 2.  Click the Template link from the sidebar of the Blogger Site main page shown below. 3.  Save the template, if you choose, by clicking on Backup/Restore in the upper righthand corner and following the instructions.  Better to be safe rather t...

Common Misunderstanding of UML

Over at Stack Overflow a question was posted " Is UML practical? ". The question itself is fine, but several of the answers were so narrowly focused. I believe that the everyday developer only sees UML as only a common set of shapes drawing a picture. Granted it has a common set of shapes for notation, but UML is first and foremost about modeling. (Big surprise coming from a Modeling Website). Where did this dis-information come from? In my experience the UML for diagrams message comes from schools/universities and popular UML books. Schools will often only teach UML as a way to diagram the solution you and your team of group participants are going to code up. Well of course it seems a little redundant in that contrived learning environment. UML's concepts are to large to teach in the same class as project management 101 or multi-developer projects 101. Most people just don't go any further with it and thus the collective knowledge is that UML is for making d...

DSMForum.org great resources, worth a look.

I have followed the DSM (Domain specific modeling) happenings online for sometime now and at best the community is scattered and most discussions/happenings limited to conferences. However, the DSMForum.org pulls this information together for easy consumption. Don't be fooled by the dated last century website design, all nerdy modeling website look that way. The DSM Publications page provides the best set of links for DSMs on the web, including podcast, conferences, and papers. Dispite one of the co-founders working for MetaCase a tool I am not currently focusing I found their coverage not too biased. The tools page they provide is nearly accurate, playing down eclipse and rational contributions a little bit, but the list represents the major players to my knowledge. RSM/RSA now has a UML Profile Tooling capability and eclipse GMF has beta WYSISYG editor the list could use rework, but a minor complaint. They also have a Linked-in group, although it is not that active.
