[mcclim-devel] Freetype for SBCL

[Brian Mastenbrook]

Hello,

Since I'm under the impression that code in the Experimental directory is, 
well, experimental, I've committed a version of the experimental freetype 
bindings which works on SBCL. I've optimized away the %SAP-ALIEN problems, 
and the end product is reasonably usable. It's a bit laggy until the glyph 
cache warms up, but after that it's just fine.

Here's a gratuitous screenshot:

I'm pretty sure that this doesn't work on CMUCL anymore, as CMUCL has 
slightly different names (DEF-ALIEN-TYPE and -ROUTINE), but a little 
macrology should restore CMUCL workingness if anybody's interested in 
giving it a try.

In order to use this under SBCL, you must use the .asd file, as there's a 
little ASDF muckery in there to work around the fact that compiling the 
freetype-ffi file currently stuffs up in SBCL. After the rest of the code 
finishes compiling, you should see a message about setting 
mcclim-freetype:*freetype-font-path* - set this to a directory containing 
the Bitstream Vera fonts, and don't forget the final / on the pathname or 
else merge-pathnames is not going to be happy.

Comments and patches welcome, especially from CMUCL users.
