Cobra Q & A
Posted: Tue Jul 21, 2009 3:20 amI've been emailing with a new user and some questions came up. I'm posting them here with answers:

Not present. I use a classic hand-coded recursive descent parser for Cobra. You can find it in workspace/Source/CobraParser.cobra. I attempted to push reusable bits up to Parser.cobra, but have not tried it out on other projects.
> * support for (mathematical) matrices (compare MatPy)
I'm sure there will be .NET/Mono libs for this. You might try http://www.google.com/search?hl=en&q=C%23+matrices and other searches. Cobra can use any library that C# and VB.NET can use.

http://cobra-language.com/samples/Download/
Note that most of that code is command line argument handling. Grabbing the contents of a URL is very easy.

Yes! I intended to work on the Reference Manual a little bit each week, but it turned out I'm too busy on coding. I think we should move those pages into the wiki. I think "Additional Documentation" is a poor name and we need a little reorg. Maybe something like:
LanguageReference
LibraryGuide -- with topics like read/write files, xml, json, get url contents, etc.
LearningGuide -- show a trail of topics as well as TO DO items to check off like reading each How To, reading each Sample, etc.
Help in this area is greatly appreciated.
