1) This formula links the latest version of the Asymptote LaTeX and ConTeXt
|
|
packages into:
|
|
|
|
#{HOMEBREW_PREFIX}/share/texmf
|
|
|
|
In order for these packages to be visible to TeX compilers, the above
|
|
directory will need to be added to the TeX search path:
|
|
|
|
sudo tlmgr conf texmf TEXMFHOME "~/Library/texmf:#{HOMEBREW_PREFIX}/share/texmf"
|
|
|
|
|
|
2) If you want to have Asymptote compiled with support for fftw or gsl
|
|
(fast fourier transforms or the GNU Scientific Library) they must be
|
|
manually installed first:
|
|
|
|
brew install fftw
|
|
brew install gsl
|
|
|
|
They are not compiled by default because they take a long time to compile
|
|
and they are not required by most users. (And they're not included in the
|
|
TeX Live build of Asymptote.)
|
|
|
|
|
|
3) If you wish to use xasy, you must first install the Python Imaging
|
|
Library (PIL):
|
|
|
|
easy_install http://effbot.org/downloads/Imaging-1.1.7.tar.gz
|
|
|
