Just for fun… sffern computes “fractal ferns”. See an example in rsf/rsf/fractal and an animated gif.

Checking parameters

July 10, 2006 Examples No comments

It its now possible to check parameters for Madagascar programs in SCons flows using CHECKPAR option like this: scons CHECKPAR=y <target> Here is what happened when I first ran an example from rsftour: 

bash$ scons CHECKPAR=y 
scons: Reading SConscript files ... 
No parameter "n2" in sfwindow 
Failed on "window n2=10 min1=0.4 max1=0.8"

After fixing self-documentation for sfwindow: 

bash$ scons CHECKPAR=y 
scons: Reading SConscript files ... 
No parameter "nc" in sfwiggle 
Failed on "wiggle transp=y poly=y yreverse=y pclip=100 nc=100 allpos=n "

Fixing that one requires changing the SConstruct file.

CHECKPAR is an experimental option and will be enhanced in the future to include parameter ranges and other safety checks. Another useful option is TIMER.

Wiki fun

July 8, 2006 Documentation 2 comments

Several new wiki pages appear now on the web site:

The last three are latex2wiki (scons wiki) conversions of the earlier LaTeX documents.
The last one also uses a new feature of sfdoc, which can now output

  • command-line selfdoc (by default)
  • fancy HTML pages (sfdoc -w)
  • LaTeX documents(sfdoc -l)
  • MediaWiki-formatted documents (sfdoc -m)

Please feel free to edit, expand, and correct the wiki pages. Have fun.

latex2wiki

June 26, 2006 Documentation No comments

A new documentation command scons wiki translates a LaTeX source into a MediaWiki formatted file.
An example: RSF Installation Instructions were generated by running scons install.wiki in book/rsf/rsf/ directory. The latex2wiki script is primitive but will be extended later as more files get translated.

Stable version released

June 10, 2006 Celebration No comments

It has finally happened!

  • RSF/Madagascar was publicly announced today in Vienna, and a stable version was released on Sourceforge.
    The stable version has vplot pens (vppen, pspen, xtpen, and ppmpen) integrated to make Madagascar a self-contained package. The vplot part may contain some bugs and is a temporary solution at best because of the licensing issues. Thanks to Joe Dellinger for permission to use his codes and for helping to integrate and test them!
  • Please check out the RSF Camp web page. A registration form is provided. The School and workshop program will be added in July.
