VectorSpace.pm on OS X
I wanted to run my VectorSpace.pm based similar entries script (here's the original article on Perl.com) on my local MacOS X TiBook for almost as long as I have that laptop, now almost 1 3/4 years. I had problems running the script on the webserver for some time longer, going for a Linux box at my former office and uploading results from there. Having VectorSpace.pm run on my TiBook would have been a nice solution... but that never really worked out. Today it did.
The problem with the code and MacOS X is it's dependancy on Perl's PDL module. Trying to install PDL via the CPAN shell is a nightmare, period. The full PDL module has tons of GUI/OpenGL and plotting features that all rely on libs that are difficult to have on OS X. And frankly I had zero use for them in any way so going down the fink path with houra of downloads was no option.
Today I finally tried it the 'hard' way. Downloading the CPAN tarball and installing it by hand via the "perl Makefile.PL; make; make test; sudo make install" route. Reading through the README told me there would be a file named perlpdl.config I could edit to omitt unwanted features. VOILA!
Telling the build process to ignore all graphic/3D features left me with a perfectly useable PDL installation.
So now I can tweak and compare different approaches for my paper w/o annoying anybody on our server.
- refactoring similar entries
- screen zoom in windows
- tracking external links with(out) AJAX
- fetters, chains
